Start your class off with a timely topic with the #iclickerqoftheweek. Ask your students to read Election Infrastructure and the Market for Voting Technology from our friends at Econofact before class (https://econofact.org/election-infrastructure-and-the-market-for-voting-technology via @econofactorg). Kick-off your classroom discussion with these questions from o ur faculty advisor, Solina Lindahl , who teaches Principles of Economics at Cal Poly, SLO, shares questions related to the State of the Union address.  Let us know how you use these with your students!  *The correct answer is noted in bold. Topic: Election Infrastructure and the Market for Voting Technology Economic Concept: Types of Firms, Industrial Organization  What type of market best describes the suppliers of voting equipment? “Dominion Voting Systems, ES&S and Hart InterCivic acquired several of their smaller competitors in the first decade of the 2000s. Together, these three companies provide voting equipment to roughly 92 percent of the voting population in the United States, according to a 2017 report from the Penn Wharton School Public Policy Initiative” ( https://econofact.org/election-infrastructure-and-the-market-for-voting-technology ) Perfect Competition Monopolistic Competition Oligopoly Monopoly Topic: Election Infrastructure and the Market for Voting Technology Economic Concept: Markets In the “market” for voting technology, who are the demanders and who are the suppliers? The demanders are the voters, the suppliers are the local governments The demanders are the local governments, the suppliers are mostly private companies The demanders are mostly private companies, the suppliers are the local governments The demanders are the local governments, the suppliers are the voters Topic: Election Infrastructure and the Market for Voting Technology Economic Concept: Firms and Profit-Maximization What type of problem is likely to be created in markets such as those described below?   “Unlike other countries that have a centralized election authority, each individual state in the United States is responsible for setting their own election standards and procedures. In practice, the majority of election management functions are delegated to county and town governments in many states, which means that the potential customers for election technology number in the thousands with varying levels of resources and technical expertise.“( https://econofact.org/election-infrastructure-and-the-market-for-voting-technology )  The suppliers will have trouble meeting the exacting requirements of powerful, unified demanders The suppliers will face low profits since their products “homogeneous” (they are interchangeable with competitors) The market is so fragmented that suppliers will have trouble developing a consistent, safe and high-quality product The market is fragmented that buyers will face too many choices of products that fit their specifications, making a decision difficult Topic: Election Infrastructure and the Market for Voting Technology Economic Concept: Firms and Profit-Maximization If you were the CEO of a voting equipment firm who faces a market described by the following, what would be your most likely strategy? “States and counties often lock themselves into ten- or fifteen-year contracts for voting machines because of how expensive this equipment is and its lack of interoperability with other systems, which requires them to completely replace their equipment if they want to switch to a different vendor.” and “vendors report that acquiring EAC certification, which some states require, can take two years or more and can run above $1 million per voting system” ( https://econofact.org/election-infrastructure-and-the-market-for-voting-technology ),  To concentrate on investing in product improvement and safety  To stick with existing technologies and avoid changes that would require re-certification  To spend money lobbying and marketing in an effort to gain contracts To engage in litigation over unsuccessful bids B, C and D are correct ...

Monica Abbott led all pitchers of the the National Pro Fastpitch (NPF) league with 17 wins during the 2017 season. Since Abbott's team -- the Scrap Yard Dawgs -- only won 31 games that year, Abbott was apparently worth 55% of her team's wins. Of course, that can't be right.  Although people in softball (and baseball) routinely assign team wins to individual pitchers, it is incorrect to think a pitcher is the sole reason why a team wins (or loses). So that leaves us with a question. How many wins do pitchers in softball really produce? Similar to what has been done for hitters in softball , this question can be answered by looking at the box score statistics. The process for pitchers begins with the concept of Fielding Independent Pitching Earned Run Average (FIP ERA).  As detailed in Sports Economics , Earned Run Average (ERA) is not the best measure of a pitcher's performance. Because earned runs depend on the fielders around the pitcher, a pitcher's ERA is not simply about the pitcher's performance.  The better (or worse) the fielders around the pitcher perform the better (or worse) will be a pitcher's ERA. The problem with ERA was originally noted by Voros  McCracken .  And McCracken also devised a better approach.  This approach -- as detailed in Chapter Eight of Sports Economics -- was adapted to data from the NPF.  The specific model involves regressing a pitcher's ERA on defensive independent statistics -- specifically strike outs, walks, hit-by-pitch, and home runs -- and one defensive dependent measure.  This last measure was Hits per Ball in Play (HperBIP), which is calculated as follows: HperBIP = [Hits – Home Runs]/[Outs + Hits – Strike Outs – Home Runs] The data employed to estimate this model included every pitcher in the NPF from 2004 to 2018 who had at least 50 innings pitched in a single season. In all, there were 221 pitcher observations. The results -- reported in the table below -- indicate that 89% of the variation in pitcher's ERA is explained by these factors. To construct the FIP ERA, we simply multiply each pitcher's defensive independent statistic by the corresponding coefficient. We then use the average value for HperBIP in the aforementioned player sample to construct each player's FIP ERA.   The following example for Monica Abbot's 2017 season illustrates the process. In column (2) we have the value of each statistics for Monica Abbott in 2017 and in the third column are the coefficients from the aforementioned model.  Multiplying these two columns -- and then summing these values -- gives us Abbott's FIP ERA. As one can see, Abbott's FIP ERA was 1.47; or a bit worse than her actual ERA of 1.17. Of course, the objective is to measure Abbott's production of wins.  To do this we follow the following steps: For each pitcher we determine the number of earned runs the pitcher surrendered that can be attributed to each pitcher's FIP stats (i.e. strike outs, walks, hit-by-pitch, and home runs).  For Abbott in 2017, her FIP stats for the season were worth -3.95 runs for the season. Abbott pitched 144 innings in 2017.  The next step is to determine how many runs an average pitcher would have surrendered with her FIP stats in that many innings. From 2004 to 2018, NPF pitchers recorded 24,908.67 innings pitched and surrendered in these innings 3,998.4 FIP earned runs. This means that per inning, an average pitcher surrendered 0.16 runs.  So, in 144 innings an average pitcher's FIP stats would have led to 23.1 earned runs. In other words, Abbott surrendered 27.1 fewer runs than an average NFP pitcher. A regression of team winning percentage on runs scored per game and runs surrendered per game indicates that each additional run scored is worth 0.085 additional wins in the NPF. This means that Abbott produced 2.30 wins more than an average NFP pitcher (i.e. 0.085*27.1). From 2004 to 2018, NPF teams won 1950 games.  Let's assume hitters produce half a team's wins and pitching and defense produce the remaining half.  So, pitchers and the defensive players are credited with 975 wins. To split the credit for pitchers and the defenders around the pitchers we will look at total runs surrendered and FIP earned runs.  From 2004 to 2018, teams surrendered 12,038 total runs. But again, the FIP earned runs were only 3,998.41. Therefore, pitchers were only responsible for 33% of the runs allowed by NPF teams. And therefore, we can argue that pitchers are only responsible for 33% of the wins attributed to the pitchers and defense.  That means, pitchers are credited with 323.8 wins. Given the number of innings pitched, this means an average pitcher produced 0.013 wins per inning. Again, Abbott pitched 144 innings.  If she was average, she would have produced 1.87 wins.  Given that she produced 2.30 wins above average, we can now see that all these calculations indicate Abbott was worth 4.17 wins in 2017. Each of those steps were applied to all pitchers in the NPF from 2004 to 2018. What follows are the top 20 pitchers -- in Wins Produced -- from 2004 to 2018.   As one can see, Monica Abbott's 2017 performance ranks 3rd all-time in NPF history.  She is also listed five more times in the list of top 20 pitchers. She never did quite as well as Christa Williams in 2005 and Amanda Scott in 2004.  But Wins Produced suggests Abbott is likely the greatest pitcher in NPF history. ... View more

When a game ends we know which team won. What we don't know is how each player contributed to the outcome we observed. Coaches -- and perhaps some fans -- might want to think that teams win and lose entirely as a team.  But that is not exactly right. Some players clearly seem to matter more than others. In basketball -- as Sports Economics details -- we can convert the box score statistics into a measure of Win Produced. We can also do something similar -- as the discussion of Reggie Jackson in Sports Economics explains -- for hitters in baseball. And now we can do the same thing for hitters in softball. According to Softball America , the top returning hitter in college softball is Amanda Lorenz of the University of Florida. Lorenz's stats are impressive in 2018.   As Softball America notes , Lorenz posted the following numbers last year: Batting Average: 0.416 On-Base-Percentage: 0.582 Slugging Average: 0.753 Home Runs: 11 Those stats are impressive. But as noted in Sports Economics , we can do more than just look at the some numbers. Once again, the numbers tracked for players can be translated into a measure of how many wins each player produced. The process begins with measuring how many runs each player creates.  Following the methodology laid forth by Asher Blass in the Review of Economics and Statistics in 1992 , we begin by regressing how many runs a team scores per game on a collection of per-game team statistics.  This was applied to college softball with data from 2012 to 2018. The results -- reported below --indicate that 94.49% of the variation in team runs is explained by the thirteen box score statistics listed. Independent Variable Coefficient t-stat p-value Constant Term 1.25 8.37 0.00 Single 0.55 48.33 0.00 Double 0.88 30.44 0.00 Triple 1.39 17.65 0.00 Home Runs 1.46 57.79 0.00 Walks 0.41 35.57 0.00 Hit-by-Pitch 0.40 14.88 0.00 Stolen Bases 0.21 11.93 0.00 Caught Stealing -0.48 -7.49 0.00 Sacrifice Flies 0.81 9.34 0.00 Strike-outs -0.19 -19.05 0.00 Double-Plays -0.46 -7.10 0.00 Ground outs -0.14 -14.58 0.00 Fly outs -0.22 -23.64 0.00 R-squared 0.9449 As both the t-statistic and p-values indicate, the estimated coefficients are all significant at the 99% level.  These coefficients can also be used to measure how many runs Lorenz created in 2018. This involves multiplying Lorenz's production of each statistic by the corresponding coefficient.  For example, Lorenz had 40 singles and the above analysis says each single is worth 0.55 runs. Therefore, Lorenz is worth 21.8 runs (or 40 * 0.55). If we do this for every statistic (as one sees in the following table) Lorenz's stats were worth 72.4 runs in 2018. Variable Amanda Lorenz production Coefficient Runs Created (production * coefficient) Single 40 0.55 21.8 Double 19 0.88 16.7 Triple 4 1.39 5.5 Home Runs 11 1.46 16.1 Walks 70 0.41 28.4 Hit-by-Pitch 2 0.40 0.8 Stolen Bases 6 0.21 1.2 Caught Stealing 1 -0.48 -0.5 Sacrifice Flies 1 0.81 0.8 Strike-outs 16 -0.19 -3.0 Double-Plays 2 -0.46 -0.9 Ground outs 40 -0.14 -5.6 Fly outs 42 -0.22 -9.1 Total Runs Created 72.4 To convert these 72.4 Runs Created into a measure of Wins Created, we follow these steps (also detailed for Major League Baseball players in Sports Economics 😞 From 2012 to 2018, all softball hitters created 349,157.22 runs (following the methodology outlined above). These hitters also had 2,796,591 plate appearances. So, per plate appearance, an average hitter created 0.125 runs. Lorenz had 250 plate appearances in 2018. If she was average, she would have created 31.2 runs. In other words, Lorenz created 41.2 runs beyond average. A regression of team winning percentage on runs scored per game and runs surrendered per game indicates that each additional run scored is worth 0.076 additional wins. That means that Lorenz produced 3.114 wins beyond what an average hitter would have created (i.e. 0.076 * 41.2). If we assume hitters produced half of a team's wins (pitching and defense produce the remaining half), the average hitter from 2012 to 2018 produced 0.0096 wins per plate appearance. This means that an average player in Lorenz's plate appearances would have produced 2.409 wins (i.e. 0.0096*250). Putting steps #2 and #3 together, we see that Lorenz's hitting was worth 5.523 wins for the Florida Gators (i.e. 3.114 + 2.409). The Gators won 56 games in 2018.  The numbers indicate that Lorenz's hitting was worth nearly 10% of this total. We can repeat this exercise for every hitter in softball from 2012 to 2018. Here are the top 10 hitters from the Power 5 Conferences (ACC, Big 12, Big 10, Pac 12, and SEC): Lauren Chamberlain (Oklahoma, 2013): 8.395 Sierra Romero (Michigan, 2015): 7.485 Kasey Cooper (Auburn, 2016): 7.460 Sierra Romero (Michigan, 2014): 7.080 Maddie O'Brien (Florida State, 2014): 7.023 Katelyn Boyd (Arizona State, 2012): 7.022 Emily Carosone (Auburn, 2015): 6.830 Lauren Chamberlain (Oklahoma, 2015): 6.788 Valerie Arioto (California, 2012): 6.628 Sierre Romero (Michigan, 2016): 6.587 Sierra Romero shows up three times on this list and Lauren Chamberlain appears twice.  Today this duo is starring for the USSSA Pride of the National Pro Fastpitch league (NPF). In 2018 , USSSA Pride won the Cowles Cup and Romero and Chamberlain were a big part of that title team. Of course, they also had quite a bit of help (the Pride have many stars). Part of that help came from the Pride's pitchers. In a future post we will discuss how to measure wins for pitchers in softball. And yes, it involves more than just observing who won the game. ...

The NFC and AFC championship games are this weekend. The quarterbacks in these games -- Tom Brady, Patrick Mahomes, Drew Brees, and Jared Goff -- are the last signal callers playing and clearly must be the best quarterbacks in the game. Right? Although these quarterbacks are the only quarterbacks with something to play for anymore, the NFL marketplace did not rank them among the best before the season started. According to Spotrac, here were the top quarterbacks in average salary in 2018. Aaron Rodgers (Green Bay Packers): $33,500,000 Matt Ryan (Atlanta Falcons): $30,000,000 Kirk Cousins (Minnesota Vikings): $28,000,000 Jimmy Garoppolo (San Francisco 49ers): $27,500,000 Matthew Stafford (Detroit Lions): $27,000,000 Derek Carr (Oakland Raiders): $25,000,000 Not only are these quarterbacks not playing this weekend, none of these quarterbacks even made the playoffs. How can the quarterbacks the market decided were the best fail so miserably on the field? The appendix to Sports Economics provides one answer. NFL Quarterbacks are -- relative to basketball players and hitters in baseball -- remarkably inconsistent. Only 31.1% of a quarterback's current completion percentage is explained by what that same NFL quarterback did the previous season. For passing yards per attempt, only 22.1% of current performance is explained by last year. And for touchdowns per attempt, only 10.1% of a quarterback's current mark is linked to last year's performance. When we turn to interceptions we see predicting the future is almost impossible. Only 0.6% (i.e. less than 1%) of a quarterback's current interceptions per attempt are explained by what the quarterback did last year. This means that you can't know how many interceptions a quarterback will throw before the season starts. Salaries are a statement about a player's future performance. The salary paid to Aaron Rodgers in 2018 was determined before the 2018 season started. This salary was set so high because the Packers believed he would perform well. But as the data indicates, the performance of quarterbacks is immensely difficult to predict. In sum, it simply isn't possible for teams to know with certainty which quarterbacks will perform well. Why is a quarterback's performance so difficult to predict? A quarterback's passes depend on his offensive line, his receivers, the quality of his running game, the plays that are called by his coaches, and the quality of the opposing defense. In sum, quarterbacks do not act by themselves and the quality of everyone else on the field -- and the coaches off the field -- dramatically impact the outcomes we assign to quarterbacks. Given all this, as chapter two notes, payroll in the NFL explains less than 3% of wins in the NFL. Yes, predicting outcomes in the NFL is very difficult. So, maybe it isn't surprising the highest paid quarterbacks are watching the playoffs this weekend. When it comes to player pay in football, teams definitely do not have a crystal ball. And the inability to predict the future will mean we will see cases where the market tells one story while the outcomes on the field tell a very different tale. ... View more

The NBA season begins this week. In most sports, the start of a new season is time for optimism.  But in the NBA --   as I detail in my latest for Forbes   -- for most teams, there isn't much reason to be optimistic. At least, if by optimism we mean "there is hope your favorite team can win a championship in 2019" then for most teams there is no real hope. This conclusion is based on the story told in Chapter Five of   Sports Economics. Basketball suffers from a "short supply of tall people." As detailed in the book, the average height of an NBA player (which is about 6-7) is somewhat rare in the world.  And 7-foot tall players - who are somewhat common in the NBA -- are immensely hard to find. Because the NBA is drawing on a very small population, the supply of tremendously gifted basketball players -- like LeBron James, Kevin Durant, Ben Simmons, etc... -- is quite limited. This means that most NBA teams must fill out their rosters with less gifted players. And the teams with less gifted players really don't have a chance. Or in other words, the NBA lacks competitive balance. Of course -- again, as detailed in Chapter Five -- the NBA has adopted quite a few institutions to address the lack of competitive balance. The NBA has a reverse-order draft, a cap on payrolls, a cap on individual salaries, and a luxury tax.  All of these institutions are designed to improve competitive balance. But because balance appears to be about the underlying population of talent --which the NBA can't change -- these institutions do not have much impact on the NBA's competitive balance problem. Fortunately for the NBA -- again, as detailed in Chapter Five -- it doesn't appear a lack of competitive balance really has much impact on demand.  So although the NBA season lacks the drama we see in other sports, we can still expect fans to enjoy watching the games and the NBA to do quite well.  But we can also expect that if you are not a fan of the few teams that are truly going to contend, the ending for your team is likely a foregone conclusion.  ...

A few more thoughts on my latest for Forbes: Few Would Take The Nobel Prize Selection Process Seriously If Applied To Sports In sports -- as noted in Chapter Six -- we have a number of metrics to answer that question. But this class isn't just about sports. It's also about economics. When people ask the question "who is the best?" in economics, often they turn to   Svergiges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel (i.e. the Nobel Prize in Economics). Economists who receive this prize are often thought of as "the best". But as detailed in my latest for Forbes, the methodology used to determine this award seems a bit suspect. Specifically, it appears the Nobel Prize is determined by less than ten people primarily from Sweden. To put that in perspective, imagine if the NFL's Hall of Fame -- located in Canton, Ohio -- was entirely determined by six people from Canton, Ohio. Or members to baseball's Hall of Fame-- located in Cooperstown, New York -- was selected by six people from Cooperstown. One suspects that many people might wonder if each Hall of Fame was really selecting "the best" with this approach. Perhaps the issues with the Nobel Prize selection played a role in the interesting story told in Chapter Four.  As the book notes, Ronald Coase received a Nobel Prize (in 1991) for the Coase Theorem. But as the book notes, what Coase said was originally said about sports by Simon Rottenberg in 1956 (well, sort of -- Rodney Fort stated more clearly what Rottenberg was saying). and as Paul Samuelson notes, the Coase Theorem wasn't really said by Coase. It was originally said by George Stigler (who also was given a Nobel Prize in 1982 -- but not for this). Yes, it is a bit confusing. But one could argue that Coase's Nobel Prize could have gone to Rottenberg. Or maybe Rod Fort! Regardless, the story of the Nobel Prize in Economics does give us an opportunity to think about how we measure performance. This is a crucial topic in economics (not just sports economics) because by being able to measure performance we can discuss a host of issues including the existence of discrimination (race, gender, nationality, etc...), whether or not workers are exploited, how managers impact performance, and many more. ...

Exploitation was defined by Joan Robinson as a worker being paid a wage less than their marginal revenue product. As noted in Sports Economics , we expect this to happen if the worker's bargaining power is limited by an employer with monopsonistic power. A good example was Major League Baseball prior to the enactment of free agency in the mid-1970s.  Another good example is college sports in the United States. The NCAA limits a college athlete's compensation to the cost of attendance. The existence of such a limit suggests a college athlete would be exploited. In fact, if that wasn't the case then we would wonder why the limit was even necessary. Although exploitation happens outside the world of sports, the world of sports gives us an opportunity to measure the size of the effect.  The first approach to measuring exploitation in sports came from Gerald Scully. In 1974 , Gerald Scully empirically examined how the reserve clause -- which forced Major League Baseball players to only negotiate with one team -- led to the exploitation of professional baseball players. The Scully approach involves estimating two relationships. First, one looks at the link between team revenue, team wins, and a collection of control variables.  From this model, we derive the dollar value of a team win. One then examines the link between team wins and player statistics.  This model is used to measure how many wins a player creates. The Scully model has been used in a number of academic articles. Despite its repeated use, though, it has some serious flaws.  For example, there is no value in the Scully model for participating in practice. A player is only given credit for producing wins in the actual games. But practice is a large part of what any athlete does and those players who don't produce wins do provide economic value to a team.  In other words, contrary to the words of Allen Iverson , it is likely practice matters. There is also an issue with the revenue model.  As detailed in Sports Economics (and a working paper I wrote with Anthony Krautmann), the value of a win in baseball changes dramatically over time.  Specifically, if we look back to the original sample Scully considered from the late 1960s, the value of a win is so large that the amount of revenue Scully attributes to the players exceeds all the revenue in the league.  In more recent years -- as noted in a paper I wrote with Michael Leeds and Peter von Allmen (and also noted in Sports Economics ) -- the impact of fixed revenues (i.e. revenues that are not impacted by wins such as broadcasting revenues), causes the estimated value of a wins to be so low that it appears most (if not all) players are now dramatically overpaid. Given the problems with the Scully model, an alternative approach is needed.  In the Marquette Sports Law Review -- and yes, in Sports Economics  -- the following method for college basketball was briefly described. We begin by looking at how pay is allocated in the National Basketball Association. As Larry Coon's NBA Salary Cap FAQ details , the NBA pays about 50% of league revenue to its players.  In addition, the average minimum pay in the first year of a contract is currently $1.71 million (minimum pay varies by years of experience). Since average pay -- or total revenue shared with players divided by the number of players in the league -- was $4.24 million in 2017-18, the NBA currently sets its minimum pay at about 35% of its average pay.   One can think of minimum pay as what a player gets for practice.  Again, practice matter. So, everyone's pay should begin with this payment. Of course, some players also produce wins and those players should be paid more. Here are the specific steps one follows to allocate revenue in terms of how many wins each player produces. For illustrative purposes, the 2017-18 women's basketball team at South Carolina University is examined. Determine how much revenue should be paid to the players : According to the Department of Education , the South Carolina's women's basketball team reported $2,046,234 in revenue in 2016-17 (this is the last year data was available). If we assume revenue was the same in 2017-18 (likely it was higher -- as revenues grow over time), and the South Carolina Gamecocks gave 50% of its revenue to its players, then the players in 2017-18 would be splitting $1,023,117. Determine average and minimum pay :  In 2017-18, there were 10 players who logged minutes for the Gamecocks. So, if the players received $1,023,117 then the average player would be paid $102,312.  In addition, if players are guaranteed 35% of the average, then minimum pay would be $35,809. Determine how much revenue will be allocated by a player's production of wins : If each player is paid at least $35,809, then the summation of minimum pay across all players is $358,091. This number is subtracted from $1,023,117 (i.e. the total allocation to players) to determine how much revenue will be allocated by wins produced.  The result of this subtraction is $665,026. Address players who produce negative wins : A player's production of wins can be measured in basketball (again, this is detailed in Sports Economics and in other places for the NBA and WNBA ). Some players, though, have an estimated negative impact. If we believe all players should be guaranteed a minimum wage, we need to address this issue.  The approach taken is to sum the wins production of all players who produced a positive quantity of wins. For the Gamecocks in 2017-18, the summation of wins for all players who produced a positive quantity of wins is 28.92.  The value of each of these wins is then $22,997 (i.e. $665,026 divided by 28.92). Determine how much revenue should be paid to each player : A'Ja Wilson -- the number one pick in the 2018 WNBA draft -- produced 7.71 wins for the Gamecocks in 2017-18.  Wilson's estimated value would then be as follows: Wilson's Economic Value: 7.71 * $22,997 + $35,809 = $213,049 In words… a player's value is simply the value of their wins production (or wins produced time the value of a win) plus the value of the minimum wage.  If a player didn't produce wins, or their wins production was negative, then that player is simply worth the minimum wage. Here are the results for all players who logged minutes for South Carolina in 2017-18. Player Wins Produced Economic Value A'Ja Wilson 7.71 $213,049 Tyasha Harris 6.61 $187,880 Alexis Jennings 4.82 $146,765 Bianca Jackson 3.13 $107,871 Doniyah Cliney 2.64 $96,602 Mikiah Herbert Harrigan 1.59 $72,390 Lele Grissett 1.21 $63,733 Lindsey Spann 0.97 $58,150 Ladazhia Williams 0.22 $40,867 Victoria Patrick -0.28 $35,809 TOTALS 28.63 $1,023,117 South Carolina won 29 games in 2017-18.  So, the estimated wins are quite close to the actual total.  In addition, the summation of economic values exactly matches the 50% split of revenue determined in step one above. The cost of attending South Carolina for out-of-state students is $47,587. This cost is the sticker price, which generally is not paid by many students.  Nevertheless, if this value was taken as an estimate of what South Carolina is paying players, then we can see that eight of these ten players are -- by definition -- exploited. So, does this analysis suggest that Ladazhia Williams and Victoria Williams are not exploited? Well, maybe not.  There is an important impact of sports that are not captured in the revenue numbers submitted to the Department of Education . A universities' sports teams provide an immense amount of advertising for the school. This is especially true when we consider " the Flutie Effect "; or the impact athletic success has on a school's admissions. The analysis reported above ignore this effect, so what we are seeing above likely underestimates a player's value. In sum, it is likely all the players listed above are paid a wage that is less than their marginal revenue product. Of course, is the measure listed above really a player's marginal revenue product? The approach taken above assumes that players should be paid 50% of league revenues.  But that is based solely on current bargaining in the NBA. In the past, the NBA gave a higher percentage of revenue to its players. Furthermore, in European soccer in the past as much as 76% of its revenue went to its players . So, what is the "right" revenue split? It doesn't appear this can be determined. What we can do is say what a player would be paid if revenues were split in a certain fashion players were guaranteed a minimum wage players were generally paid for wins When we take that approach, it appears the basketball players for the women's basketball team at South Carolina in 2017-18 were generally underpaid.  In other words, exploitation was the norm. This is not an unusual story in college sports. Exploitation is not simply something that happens in men's basketball and football.  We can find players that would likely be paid more than the cost of attendance in a number of sports; if the NCAA had to pay like a professional sports league. Again, this is what economic theory would predict.  The advantage of sports is that we have the data to examine this prediction. ... View more

Chapter Nine of   Sports Economics   begins with a story many may know (or not!).    The highest paid public employee in most states is either a head coach in college football or college basketball.     When we looked at revenue in Chapter Nine of the book, though, the amount paid seemed somewhat odd.    For example, Pete Carroll was paid $7 million by the Seattle Seahawks of the NFL in 2015; a team that had $377 million in revenue. That same year Nick Saban was paid $7.1 million by the University of Alabama. But the football program at the University of Alabama only reported $97 million in revenue. While many of us think about the men's NCAA basketball tournament we should remember a similar revenue-salary story can be told in basketball.     USA Today   recently reported the salaries of the head coaches in men's college basketball.     According to this report, Mike Krzyzewski of Duke University, John Calipari of Kentucky, and Chris Holtmann of Ohio State are all paid more than $7 million per year.     HoopsHype, though, says only three NBA head coaches -- Gregg Popovich, Doc Rivers, and Tom Thibodeau -- are paid this well.     But just like college and professional football, if we look at the revenues of men's college basketball and the NBA it is hard to understand why coaches in both levels of competition would be paid similar wages. Well, it isn't that hard to understand.   NBA teams pay their players 50% of their revenue. The NCAA, though, significantly restricts payments to college athletes. Therefore the money in generated in college basketball has to go someplace else.     One "someplace else" is in the paychecks of the head coaches. Let's imagine a world, though, where college coaches were paid like the NBA.   According to Forbes.com, the average NBA team generated $245.6 million in revenue in 2016-17 while   HoopsHype   says the average head coach is paid $5.9 million per year.     So the NBA pays on average 2.4% of its revenue to its head coach.     What if men's college head coaches were paid in the same fashion? Universities report the revenue of each athletic team to   the U.S. Department of Education . The last year the data is reported is from 2016.     If we assume those revenue numbers haven't changed too much (which may not be a great assumption!), then we can use these 2016 revenue numbers to calculate what each head coach in men's basketball would be paid if their pay was restricted to 2.4% of team revenue.   For example, Duke University reported $34.3 million in revenue for men's basketball in 2016. If Coach Krzyzewski was paid 2.4% of team revenue his pay would be $823,498; or more than $8 million less than he is actually paid today. Once again,   USA Today reports   what college men's basketball coaches are actually being paid by their schools. And here is what the thirty highest paid college coaches would be paid if they were paid like NBA head coaches: Mike Krzyzewski (Duke University): $823,498 John Calipari (Kentucky University): $669,490 Chris Holtmann (Ohio State University): $436,908 Bill Self (Kansas University): $437,297 Tom Izzo (Michigan State University): $420,115 Sean Miller (Arizona University): $561,032 Bob Huggins (West Virginia University): $163,895 Larry Krystkowiak (University of Utah): $209,582 John Beilein (University of Michigan): $404,903 Archie Miller (Indiana University): $587,989 Shaka Smart (University of Texas): $420,578 Lon Kruger (University of Oklahoma): $315,788 Gregg Marshall (Wichita State): $177,784 Tony Bennett (University of Virginia): $204,811 Avery Johnson (University of Alabama): $359,189 Scott Drew (Baylor University): $217,789 Frank Martin (University of South Carolina): $286,055 Brad Underwood (University of Illinois): $378,902 Buzz Williams (Virginia Tech): $225,720 Mark Turgeon (University of Maryland): $424,729 Dana Altman (University of Oregon): $266,927 Cuonzo Martin (University of Missouri): $240,974 Steve Alford (UCLA): $321,201 Jay Wright (Villanova): $266,223 Mike Anderson (University of Arkansas): $391,011 Michael White (University of Florida): $339,960 Bruce Pearl (Auburn University): $237,022 Will Wade (LSU): $194,770 Matt Painter (Purdue University): $243,510 Mike Brey (Notre Dame): $93,289 A few notes on this list.     First, the average salary for this group is $3.5 million and this average pay works out to 27.1% of average reported revenues. If these coaches were paid like the NBA, though, the average pay of these coaches would only be $344,031.     So if these coaches were paid like NBA coaches then on average each would see a pay cut of about $3 million (similar to what I said about Sean Miller at the University of Arizona earlier this month). In addition, none of these head coaches would be paid as much as a million dollars per year. And Mike Brey's pay wouldn't be much different than a professor at Notre Dame. Brey's school only reported $3.9 million in revenue in 2016 from their men's basketball team and his currently salary is 61% of this total. But if NCAA paid like the NBA, Brey would receive less than $100,000 per year.  To the best of my knowledge, no college coach has come forward to advocate that the NCAA pay players and coaches as they are in the NBA.     And given these numbers, there isn't much incentive for any coach to advocate such a change.     But it is interesting to see what a less restricted market would look like.     The picture painted suggests that many NCAA coaches are not going to want to live in a world where NCAA athletes are better compensated for their efforts and coaches… well, they get much, much less. ...

One of the stories told in   Sports Economics   is that we can use data from sports to measure the economic value -- or what economists refer to as "marginal revenue product" -- of an athlete.     All one needs is a measure of a worker's productivity and data on revenue from the sport.     In fact --   as I recently demonstrated at Forbes.com   -- sometimes you can make an estimate with just data on revenue.      Sports Economics   reviews three different approaches to measuring a worker's value. The one I prefer is the approach taken in Chapter Nine to measure the economic value of each member of the men's basketball team at Duke University. Here is how this was measured: The U.S. Department of Education   reports that revenue for the men's basketball team at Duke University was $33.8 million in 2014. In the NBA (as well as the NHL), the players are paid 50% of league revenue.     If Duke University followed that approach, then $16.9 million would be paid to the players that season. If this revenue was allocated according to how many wins each player produced for this team, then a player like Jahill Okafor -- who produced 6.5 wins in 2014-15 -- would be worth more than $3 million. Obviously, this is far more than the cost of attending Duke University. And that means Okafor was paid less than the revenue he generated. That also means -- by definition -- he was exploited. In November I applied the same approach at Forbes.com   to the study of women's college basketball. This analysis indicated that Gabby Williams -- who produced 11.0 wins for the University of Connecticut in 2016-17 -- was worth about $550,000.     And once again -- as we saw with Okafor -- this means Williams was exploited. Then this past week I used a somewhat similar approach at Forbes.com   to measure the economic value of women in college hockey. Because I don't have data on how many wins each hockey player produces, though, I took a slightly different approach. If we assume the NHL can measure wins (not entirely sure that is correct!) and that the NHL is paying players for their wins production (not entirely sure that is correct!) then we can use the distribution of salaries in the NHL to see how revenue would be allocated in women's college hockey if colleges followed the NHL model. The results indicated that -- on average -- the women of Team USA generated more than $140,000 in revenue their last year in college. And given the value of a scholarship, that suggest many of these women were exploited. There have been two objections raised to this analysis.     First, people wonder about teams who have expenses greater than their revenues.     In discussing expense data in colleges we must first note -- as mentioned in Chapter Nine of Sports Economics   -- that this data seems problematic.     Specifically, for about half the women's college basketball teams analyzed the   revenue data self-reported to the U.S. Department of Education   was exactly equal to the expense data that was self-reported. This is odd because - as any student of economics should understand -- the process that determines a firm's revenue is largely independent from the process that determines its costs.     For these two numbers to be exactly equal suggests something unusual happening.   In   Sports Economics   it was argue that "something unusual" was related to the non-profit status of schools. Non-profits -- like universities -- have an incentive to spend all their revenues.     So as revenues rise so will expenses.     And if athletic departments can, they will spend even more than the revenues that are accrued.     In other words, expenses can exceed revenues. Can workers be exploited if expenses exceed revenues? Again -- as any student of economics should understand -- that is most definitely possible. A worker's value is a function of how much output that worker produces and the revenue that output generates. It is entirely possible for a firm to receive more revenue from a worker than it pays the worker in wages; and through mismanagement of the rest of the firm end up having total costs in excess of total revenues. When that happens, the worker is still exploited.   Let me give an example to illustrate this point. Imagine you worked for a firm and you generated $50,000 in value but the firm only paid you $30,000.     By definition, you are exploited.     But let's say your boss now told you that the firm was losing money. Does that mean you are no longer exploited?     Of course not. You are still generating more money than you are paid.     The fact your boss can't manage the firm doesn't change the definition of exploitation. Now that we understand what it means to be exploited we should emphasize that not all college athletes are producing more revenue than what they receive in a scholarship.     This leads to another issue people have raised.     Should players who are not exploited be paying for some of their college education? I imagine that is a possible outcome. But I think that's unlikely. One issue to remember is that the revenue numbers reported to   the U.S. Department of Education   are about ticket sales, broadcasting revenue and donations (yes, donations count!).     But these numbers do not include a measure of how sports promote the name of a university. For example, how many people in the nation would know about Gonzaga University without its men's basketball team?   That marketing effect is part of the value of athletics to a college. Therefore, it might make sense for a school to spend more on athletes than the explicit revenue the athletes generate. So how much should athletes ultimately be paid?     Patrick Hruby offered this answer to that question a few days ago. "So what is the best plan for paying players? No plan at all.   If Kentucky wants to offer basketball recruits $500,000 signing bonuses, fine. If  Notre Dame  doesn’t   want to offer football recruits a penny more than their athletic scholarships , that’s also fine." I would agree with this plan.     Outside of college sports firms and workers are free to negotiate any deal that is consistent with the nation's labor laws.     So, if Duke University wanted to pay Jahill Okafor $3 million, that should be fine.   Likewise, the University of Connecticut can pay Gabby Williams $550,000 and the University of Wisconsin can pay Meghan Duggan more than $230,000 or Hilary Knight more than $700,000. Of course, it's possible these athletes might also negotiate a salary that is less than these values. In the end, though, this should not be the business of the NCAA or the government.     What wage these athletes get paid should simply be the business of the schools and the athletes. Of course, if those deals result in an athlete generating more revenue than they are paid then once again, we would say they are exploited.     But the reason now would be different.     Now we know college athletes are exploited because of the rules created by the NCAA.     If exploitation existed when these rules were eliminated we would then have to think harder about what is going on in the labor market. And that will be a story we will discuss, if and when that ever happens! ... View more

The NBA season is grueling.     Players report in September and the season ends in April, Of course, if your team is successful you might compete until June.     But for most players, the entire season is not much more than six months long. For the women of the WNBA the story is different.     Training camps open in April and the season ends in September.   So like the NBA, the WNBA is about a six-month commitment. But when the WNBA season ends,   the majority of the players join a league in another country .     This means that for many women, professional basketball is a year-long job. Economists have a habit of thinking that money is the only thing that motivates people. Often that approach to human behavior is too simplistic.     But in the case of the women who play professional basketball, money really seems to be a huge issue. As noted in   Sports Economics   (and updated for   this article at Forbes ) there is a significant gender-wage gap between the NBA and WNBA. Give the WNBA's minimum ticket price, attendance, and television broadcasting deal the league earned at least $51.5 million in revenue in 2017. But the league paid less than $12 million to its players. So the players were paid less than 25% of the league's revenue.     And this is an overstatement of the amount received. In contrast, the NBA pays 50% of its revenue to its players.     The gap between the best players and the average player in the NBA is also much wider.     Steph Curry receives a maximum wage in the NBA.     But if this wage was determined as it is in the WNBA,   Curry's wage would fall from $34.7 million in 2017-18 to less than $5 million.     And that would be the outcome even if the NBA's revenue didn't change. In other words, the best players in the NBA have a huge incentive to solely focus on their NBA career. In contrast, players in the WNBA need to think of other ways -- besides playing for the WNBA -- to earn a living. As s consequence, we see labor market outcomes that are not found in other major men’s professional sports.     For example,   Diana Taurasi was paid by UMMC Ekaterinburg (the Russian team she also plays for) to NOT play in the WNBA in 2015. And now we are seeing something similar.   Emma Meesseman has been with the Washington Mystics   since 2013, playing primarily as the starting center since 2014.     From 2013 to 2017 she produced 17.6 wins (see   Sports Economics   and   The Ladies League   for how this is calculated).     This represents about 20% of the team's wins across these years.     In sum, Meesseman has consistently been a good player. But as   Ava Wallace of the Washington Post reports , Meesseman is not playing in the WNBA in 2018. As Mike Thibault -- General Manager of the Mystics -- stated:   “Emma has played year-round for almost six consecutive years, without time to rest her body from the wear and tear that results from that kind of schedule.” Meesseman is only 24 years old.     But playing year-round for six consecutive years takes it toll.     So now the WNBA will be missing out on one of its better players in 2018. The solution to this is simple. The WNBA has to follow the lead of UMMC Ekaterinburg and find a way to pay its players enough money to play less basketball. Such a move wouldn’t just make it better for WNBA players.     As I argued recently for Forbes,   higher pay for players is also in the interest of the league. More pay for players could lead more girls to devote time to playing basketball. As argued in   Sports Economics, expanding your talent pool leads to more competitive balance.     In sum, more pay today can make the WNBA better  tomorrow .     So, it’s in the WNBA’s interest to do what it can to make sure players like Meesseman do not make similar choices in the future.     But to make that happen, the WNBA has to get more money to its players today. ...

With less than three minutes to play in the Super Bowl, Tom Brady and the Patriots needed a touchdown to win the Super Bowl.   Last year Brady and the Patriots overcame a 28-3 deficit to win their fifth Super Bowl.   So many people watching were expecting yet another Brady comeback. Two plays later, though, disaster struck.   The Eagles sacked Brady and forced a fumble. A few plays later the Eagles kicked a field goal to give them an eight-point lead. But again, Brady got the ball back with over a minute to play.   Despite being given another chance, though, Brady couldn’t find any magic.   After not making much progress to move down the field a last second Hail Mary fell to the ground in the end zone.   And with that, Brady and the Patriots went home losers. So, what happened to Brady? If you think you know, check the data.   As the very last pages of Sports Economics reports, quarterbacks – no matter how you measure performance – are very inconsistent.   At least, relative to athletes in basketball, what a quarterback does from season-to-season is hard to predict. The reason for this is simple.   A quarterback’s performance depends on his teammates.   A quarterback requires linemen to block and receivers to catch for a pass play to work.     It also helps to have a reliable running game.     Plus the decisions of offensive coordinates – who often call the plays – also matters. A few things could have happened on Brady’s fumble. Maybe his line could have blocked better. Maybe his receivers could have done better to get open. Maybe the play could have been different. Or maybe everyone else was playing well and Brady simply didn’t pass the ball quick enough and/or didn’t maintain ball security. All of this means that researchers who wish to use American football data to answer questions in labor economics have a problem.   Researchers wish to use data from sports to measure the marginal productivity of athletes.   But because the stats we use to track individual performance in American football depend on the player’s teammates, this data really can’t be used to measure marginal productivity.   So, researchers who need marginal productivity data to answer economic questions… well, they might want to look for another sport!   ...

When I mentioned to friends that I was planning a trip to Kazakhstan, the most common response was “that’s where Borat is from”, referring to the fictional character portrayed by Sasha Baron Cohen in the popular 2006 comedy film. But unlike the impoverished backward nation portrayed in the movie, visitors to Kazakhstan will find a destination far different than one might imagine. Kazakhstan is a mountainous country, nestled in Central Asia with the Tai Shan Mountains serving as a backdrop to Almaty, its largest city. Economically, Kazakhstan had benefited tremendously in the late 2000s and early 2010s when the price of oil and natural gas (its most abundant resources) peaked. But unlike other developing countries which had squandered their oil wealth due to corruption, Kazakhstan invested heavily in infrastructure and education, leading to beautiful, modern cities with wide avenues and efficient public transportation systems. Kazakhstan’s emphasis on education, especially science and math, can be tied to its important role as the home and original launch site (which remains today as a result of a lease agreement between Kazakhstan and Russia) of the Russian Space Program. Ensuring all citizens have access to both primary and higher education is a key government priority that has led Kazakhstan to experience rapid economic growth. A visit to Astana, the capital, might confuse a weary traveler with other dynamically growing cities such as Dubai or Shanghai. Kazakhstan’s infrastructure development allowed it to bid for the 2022 Winter Olympic Games. Although it lost its bid to Beijing, Kazakhstan made a positive impression on the Olympic Committee, making a future bid more likely to be successful. And perhaps the most striking observation of Kazakhstan is its people. Most Kazakhs resemble the Chinese more than Russian in physical appearance. In terms of tourism, although there are plenty of hotels, modern airports, and beautiful attractions, one will find very few American and European tourists. For that reason, very few Kazakhs speak English, and English signs are not very common. But that should not deter one from visiting this beautiful country. Just turn on the Google Translate app, and venture out and interact with some of the most-friendly people in the world. - Eric Chiang, Author of Economics: Principles for a Changing World ...

Among the most famous and popular animals in the world is the panda bear, whose existence in the forests of central China had been threatened by deforestation and economic development throughout the 20th century. Since the 1970s, however, conservation efforts have allowed the panda population to nearly double, allowing scientists and tourists from around the world to observe their majestic qualities and playful personalities. On a recent visit to Chengdu (currently the fourth largest city in China with a population of over 14 million), I enjoyed a unique experience unavailable anywhere else in the world. In the foothills of the Qionglai mountains about an hour’s drive west of Chengdu is the Dujiangyan Panda Research Center, which is home to approximately 20 pandas including U.S.-born pandas Tai Shan (born in 2005) and Bao Bao (born in 2013), both of whom were born in the National Zoo in Washington D.C. and subsequently returned to China under the panda lease agreement. Unlike many zoos outside of China which are privileged to host usually at most two pandas at a time, the Dujiangyan Panda Center allows tourists to visit over a dozen pandas for a small admission fee of about $12. However, for a significantly larger “donation”, one can experience pandas much more up close. For a payment of about $120, one can become a “volunteer” for the day, helping to prepare food for the pandas and cleaning up their dens. But the ultimate experience requires one to plunk down an additional $300. This buys you 20 seconds to sit alone with and hug a panda cub, just enough time to capture priceless memories via photos and video. Despite the hefty fee, demand is very high and the experience (limited to 20 persons per day) sells out weeks in advance. All of the funds collected are used to advance further conservation efforts, which has recently allowed the panda to be removed from the endangered species list. - Eric Chiang, Author of Economics: Principles for a Changing World ...

Among my most memorable trips in recent years include visiting remote towns in the Arctic, where there are no roads connecting to other towns, and limited access to waterways due to the sea being frozen for much of the year. In two towns that I visited, Barrow, Alaska, and Iqaluit, Nunavut, the only viable means of transport for passengers and goods is by air. For most of us urban-dwellers and rural residents who live in towns connected to one another, we are accustomed to seeing prices of everyday consumption goods based on the cost of raw materials and other inputs that contribute to their wholesale price. The difference in retail prices between a department store in Akron and a convenience store in Los Angeles is based on factors such as competition, economies of scale, and taxes. But one input we often take for granted is the transportation cost, given the efficiencies of the shipping industry that allow goods to be transported quickly and efficiently throughout the country. However, in the Arctic north, prices are largely dependent on transportation costs, because everything other than the few locally-made items is delivered by air. Therefore, retail markups are largely calculated based on the wholesale price plus a large premium for the air freight. Consequently, prices for heavy household items such as laundry detergent and cat litter that typically sell for less than $10 at a Walmart or Target can be five to ten times that cost in Iqaluit. Moreover, heavy items that are also perishable such as orange juice and milk can have an even higher markup. Meanwhile, goods that are relatively light and have a longer shelf life, such as microwave popcorn, have prices that are much closer to what we are used to. Visiting towns that are largely cut off from the rest of the world provides a unique perspective to market pricing, which subsequently influences the goods that residents in these faraway places consume. ...

Well, sort of. Eric Chiang​ and I arrived in Dubai from South Africa late last night for our final and briefest stop on the Around the World tour. One of the first things I noticed when we arrived was this bottled water with the slogan, "water is life." Makes sense, I thought. Dubai is one of the United Arab Emirates on the Persian Gulf just East of Saudi Arabia, so got really salty water on one side and then one of the driest deserts in the world there, so a certain amount of reverence for fresh water is logical. One thing you need to know about Dubai is that everything is over the top. It's like Vegas meets New York City. The United Arab Emirates are of course extremely rich in oil (the federation is an OPEC country), and Dubai, recognizing that eventually the wells will dry up, has been in the process of reinventing itself as a cultural and banking hub in the middle east. Excess is everywhere, but it was still a bit surprising to find myself staring at a giant aquarium (complete with sharks) in the middle of the Dubai mall: If that wasn't enough, they've got a man made lake (with boats of course) and fountain shows every hour that put the Bellagio in Vegas to shame. For what a country with what I figured had a cultural reverence for fresh water, they seemed to be flaunting the water they did had, and that's the point. The reason we were there was to talk about factors of production. I mentioned this in my last post with the lions: basically the three main factors that go into producing anything are land, labor, and capital. Like South Africa, Dubai wanted to solve an economic problem and restructure its economy to not be as reliant on oil. So how did they do that with the production factors they had? Well they don't have much labor since the country's population is so small. In terms of land, they have a ton of oil which in turn generates lots of capital, but they don't have resources like fresh water to allow their city to grow, and they don't have a decent natural port to facilitate trade. Now there's kind of a 4th factor that's often lumped in with capital, and that's innovation or entrepreneurship, and Dubai has that in spades. Basically, they've done a lot of things right; one of first things the UAE did after its incorporation was to develop a comprehensive education system, including universities. They've also provided incentives for foreign schools like NYU, American University, and even the Sorbonne to set up campuses there. They used their investment capital to develop their intellectual capital (innovation). Need fresh water? Use both your capital and innovation to build desalinization plants. Need labor? Use your capital to provide incentives for labor forces from India, Pakistan, and Russia to work there (85% of Dubai's population is expats). Want to draw attention to your city as world hub? Use your innovation, capital, and new found labor to build the tallest building in the world (Burj Khalifa): If you've got enough capital and labor you can even build a port from scratch. The point is, if you use the production factors that you do have wisely, you can overcome deficits in factors you don't have. With a population of 2.5 million and a bustling tourist trade enjoying world class shopping and even an ice rink and man-made ski mountain in the middle of the desert, Dubai is a success story in that regard. Up next, planes, trains, automobiles, and the conclusion of this blog. ... View more

You might remember a short time ago there was somewhat of a controversy over a dentist from the US "mistakenly" killing a famed and beloved lion, Cecil, for sport. It was illegal both in Zimbabwe, where it occurred, and you can't import trophy animals into the US. The controversy stems from the fact that there's a strong economic argument for limited legalization of both these things. Ok, Econ 101. The three main factors of producing anything are land, labor, and capital. You can think of land as any natural resource, i.e. Lions (sorry, Cecil). If you're Zimbabwe or say, South Africa, and you have a major income inequality problem, and you're rich in both natural resources and labor, but have issues with the 3rd factor, how do you best use the resources that you have to solve the problem? One solution, favored by Kenya, is to sell a limited number of lion permits to hunters for a very high price. This revenue goes straight back to game parks to conserve the rest of lion population, the permits are ONLY for specific lions (these particular lions are chosen because they would have to removed from the population for biological reasons, anyway), and finally hunters of that wealth spend a lot of money on guides, etc. that goes directly to the local economy. They key is that this lion population has to be managed responsibly and the country needs to have solid institutions to make his work; Kenya has this, Zimbabwe does not. Of course, this is controversial even from an economics standpoint, and you can listen to the con argument on this great episode of Radio Lab. Of course, there's an alternative to utilizing your "lion resource" this way, and that's to rely on relatively low impact eco tourism as South Africa does. Eric Chiang​ and I actually didn't think we'd have enough time to explore the Johannesburg Lion Park, but Elias, being awesome, just said, "YAH! We can make that happen." So we went on "safari." It was an amazing experience. We saw springbok (South African national animal), zebras, water buffalo, cheetahs, wild dogs, and of course, lots of lions. I'll try to post as many photos as I can buy I want to point out two things. First, it wasn't a zoo, it was a game park; meaning that the animals had hundreds of acres of free range. Second, it seems to be run well and it was generating lots of income for the local economy both through admissions, photos, and souvenirs. Thomas Acox​, get ready for your new Zulu fly swatter. Your adventures Eric Chiang​ and Thomas Digiano​. By the way, the rumors are not true. Eric was not attacked by this lion cub, he was merely nibbled upon.

Johannesburg is a city of extremes. Within less than a mile of each other there are areas of affluence and areas of abject poverty. Without mincing words, it's a dangerous city. To be on the safe side, Eric Chiang​ and I stayed in one of the nicer areas, Sandton. Due to the generous exchange rate (15 rand = $1) we were able to stay at a pretty swanky hotel for less than $200. Why not just a normal Hilton? In order to visit the not-so-nice places like downtown Johannesburg, you need a hotel with a good concierge service to find you a driver/guide to take you there (they're supposedly that dangerous). I promised my fiancee I'd be back in one piece and I also promised my new bosses I'd bring Eric Chiang back in one piece, so we opted for a nice option and we got Elias, so good call there. Here's a picture of Mandela Square, which was right next to the hotel: Sandton has the look and feel of Beverly Hills, so we wanted get out and see what downtown Johannesburg was like. Typically highest crime and poverty rates are on the outskirts of townships, ironically called "suburbs", where truly low income individual were forced from government housing. Elias told us that the downtown of Joburg was actually a pretty nice place up until about 15 years ago, but when wealthy people flocked to areas like Sandton, where newer, bigger, and more luxurious housing could be had, it developed a serious case of urban blight. There are a few remnants of the former affluent culture: a heavily barred BMW dealership, but for the most part it's a lot of urban blight: Elias wouldn't let us out of the car here, but honestly I've seen areas of the Bronx and Brooklyn that looked just as rough if not rougher. Still, we didn't want to risk it, and after we got an impression of the place, we continued on to Soweto. As I've mentioned, Soweto is the area of Joburg where both Bishop Desmond Tutu and Nelson Mandela are from (the same street actually): Like some of the area names in New York (ie, SoHo), Soweto actually simply stands for Southwest Township. It's actually a collection of neighborhoods that were formally incorporated when the apartheid government decided to build tracts of ramshackle housing in order to relocate Bantu people from more desirable area. It's the largest township and was the seat of the anti-apartheid movement for almost 40 years. if the 2 mile or so distance between Sandton and downtown seemed like a case study for income inequality, then Soweto is a thesis in itself. The houses at the top of Soweto's sloping streets, are decent brick affairs that you might see in Southern California, except for the fact that they are all walled in and most have either razor wire or cameras on their exterior. Mandela's house is towards the bottom part of this neighborhood and it's interesting to see how a restaurants and shops have sprung up around it from the tourist dollars it draws in (the house is a museum). As you move down the hill, the houses turn to more regimented government-built affairs. Minimal electricity and running water, and to me at least, they look a bit like German POW camps from WWII: Finally, beyond these houses are the "suburbs" where the poorest of the poor have been relegated. These are the types of shanty towns you see in National Geographic: tin shacks, burning trash, goals and livestock roaming around, and one spigot to provide water for the whole village. I struggled with writing this post. We were being driven through these scenes in a new silver Mercedes with a driver who came from a similar area (the hotel owned the car). Part of me still feels guilt over this, but then the reason why we were there in the first place was to help educate people about terrible economic problems like this. Mandela's fame is obviously the big tourist draw for the area, but I know that we weren't the only tourists Elias drove through these other parts of Soweto, and I really think he does so for the harshness of the economic reality to hit home. I could hear it in his voice when he spoke about the place. The last I want to mention about Soweto is that the Chris Hani hospital is located there. This is the hospital I mentioned in my first Africa post - it's the third largest in the world. Like much of Africa, Johannesburg is suffering from an HIV epidemic, and the Hani hospital treats literally thousands of patients suffering from AIDS. Elias mentioned this as we drove by, and pointed out that it was visiting hours. On the bright side, we did see evidence of a pretty substantial government campaign promoting safe sex, and there were other clues as to the government's efforts to Reduce poverty and lessen the income gap. Next up, a lighter post: LIONS ! ... View more

I recognize this is supposed to be a live blog, but I have to be honest and let you know that I'm actually writing this while flying over the African continent on the way to Dubai. I'm letting you know this because the following posts are out of chronological order. Even though it wasn't the very first thing Eric Chiang and I did when we arrived in Johannesburg this morning, I need to start with our visit to the Apartheid Museum because apartheid really sets the stage for any discussion of economics in South Africa. First things first, this is our guide, Elias: Elias is amazing. He speaks 7 languages fluently, and is unfailingly polite, upbeat, and savvy. He knows the history of South Africa as someone who lived through some of its most tumultuous periods. He was born in 1976 in Alexandra, probably Johannesburg's second most famous township for reasons I'll get to in just a minute. On the way to the museum he told us about his own experiences with apartheid when he was at a government-run school: corporal punishment, cops shooting tear gas canisters in to classrooms - all really grim stuff. He basically told us that we'd feel terrible when we left the museum, and he was right. Here's an outside shot of the apartheid museum: The museum seeks to make an impact before you've even entered the doors... which are segregated. Here's my admission ticket (Eric Chiang's was for whites): In a lot of ways the museum is overwhelming, so let me try to distill it down to a few key points: 1.    Economics was a big part of apartheid. First, some of its roots start with the Boer War in the late 19th century, where the British colonial force came in and basically tried to wipe out the Zulu tribes and Boer (Dutch) settlers in the area. Why? They found diamonds in the Northern part of the country. This shattered any independence the Zulu kingdoms had and forced them into an uneasy colonial state with the Dutch settlers and the English. Second, gold was later discovered around Johannesburg. South Africa’s capital isn’t a port or on a trade route, it’s a mining town, and gold mines still dot its landscape. Here's one right beyond the soccer stadium built for the 2010 World Cup (the yellow mound): From here, you can probably piece it together. The white mine owners needed massive amounts of cheap labor to work the mines, which was in turn supplied by the Bantu (term for any native African), because they could no longer farm or support themselves independently under colonial rule. 2.    Apartheid was a codified set of laws: So wealthy [powerful] white mine owners really needed cheap Bantu labor to support the growth the mining industry, but they were concerned about being overrun since population-wise they were in a minority and were forcing deplorable conditions on the labor force. This is a common theme you hear in the interviews of the people who drafted the apartheid laws. As the industry grew, they drafted more and more laws to keep the Bantu population in check (most of which were aimed at keeping them from obtaining economic independence). Here’s a picture of a museum wall depicting all the laws: Side note: I felt inclined to draw comparisons with Jim Crow laws in the US, but most of these apartheid laws were drafted in the second half of the 20 th century. It's all so very recent. Additionally, Jim Crow laws just weren't nearly as extensive or instituted on a national level to specifically keep industry going. 3.    Apartheid was about displacement : Make no mistake, racism was of course the driving force behind apartheid. Wealthy whites did not want to live amongst their Bantu labor force, and as whites grew wealthier and the population grew, they continually forced large segments of the Bantu populations to townships like Elias’ Alexandra and Soweto, where Nelson Mandela was from. Not coincidentally, there were massive housing shortages, and the apartheid government built what were essentially slums to exercise further control over the population. So those are my takeaways from the museum. I'm definitely oversimplifying things, and I’m not any sort of an expert, but I hope I’ve gotten across just intertwined economics is in all of this. Up next, we got to the most famous Johannesburg township, home of Mandela and Bishop Desmond Tutu, Soweto. ... View more

"I bless the rains down in Africa / Gonna take some time to do the things we never had..." Aside from Toto making almost zero grammatical sense in their  famous 80's hit, I always thought they were singing that they missed the rains down in Africa. Makes me think of lush, verdant jungles or a soft rain on the Serengeti. I get that. What's with the beatitudes? Also, Hakuna Matata is a Swahili expression, and originates from somewhere around Kenya rather than way down in South Africa. They've got Zulus (warriors) down here, and I don't think those guys have too many delightful little quips that Disney is going to adopt any time soon. So if you forgive my little aside there (these posts are probably going to get weirder the more sleep deprived I become), I brought those things up because they're both misconceptions about Africa. More to the point, I think the average [American]  just doesn't know too much about Africa or South Africa in particular. At least I didn't. The other reason I wanted to start off with some levity is that we came to South Africa to examine the economic concept of income inequality here. That, in and of itself, can be a very difficult topic for many people to write about (myself included), and it's made even more difficult by just how incredibly stark the disparities in income are in South Africa. The economics behind  income inequality here in South Africa might not actually be that complex, but the socio/political history of course is. Take South African currency, the rand, for example. Who's the most famous South African you can think of? Former President and Nobel Peace Prize winner, Nelson Mandela, right? Well, all the paper money here has his face on one side, and only his face: The other side of the bills features different native wildlife - safe, non-political animals. Why the focus on Mandela? He certainly wasn't the only activist leader fighting apartheid; the Johannesburg airport is named after his partner in his law practice, O.R. Tambo. The largest hospital in Johannesburg (3rd largest in the world!) is named after assassinated SACP leader, Chris Hani. Mandela was undoubtedly a great man and did a great deal to end apartheid, but I think in some ways he's become a safe figurehead. South African history is bloody, complex, and many of its wounds are not too far in the past. I think it might be difficult to so prominently feature other leaders without aggravating some of these wounds. We had another whirlwind day in Johannesburg, so coming up I'll try to focus on the three major parts of our day here; the apartheid museum, a look at Soweto Township, and LIONS. ... View more

This afternoon, Jeffrey Young of The Chronicle of Higher Education, interviewed Christine Ortiz, dean of education at MIT, as a follow up to the article he wrote last month on a new nonprofit university she is leaving MIT to start, that provides students with a well-structured global education experience in a non-traditional format.  She shared some of her interdisciplinary vision via a slide that highlighted personalized learning in the knowledge domain, core science and engineering, and humanities, arts and social sciences (visualization credited to Jason Chuang).  Ortiz emphasized students being engaged, passionate, and that they would have flexibility in their day.  She sees the new classroom as focused on project-based learning and investigation to advance students to higher levels of learning, led by mentors (more one-on-one interactions versus standard lectures). The curriculum will not only be STEM but will incorporate the humanities, and it will have accreditation in place to insure quality.  How do you create global educational experiences in your classroom? What project based learning assignments have you done successfully? If you’re looking to incorporate more active learning in your economics classroom, Worth Economics supports your efforts with EconED Active, a site dedicated to open resources for active learning in your classroom.  And follow our author Eric Chiang and Marketing Manager Thomas Digiano  as they travel around the world to gather ideas for taking your Principles of Economics course global.

Before I leave our adventures in Brazil and turn to South Africa, I wanted to round back to on a point I made earlier about what effect the slow down of the Chinese economy might have on the Brazilian economy. Also, we just saw a guy literally jump off a bridge (he's ok): Eric Chiang​ being the consummate world traveler, actually researched how much the taxi ride from the airport would cost us: about 100 Brazilan reals or about $27. The cost ended up being 120 reals, and in fact we found that most prices were about 20% more than expected due to inflation. Historically, Brazil has had lots of problems with inflation. In fact, as recent as the early 1990's, they had hyperinflation, where average goods would costs millions of reals and the price would radically fluctuate to the point where consumers couldn't effectively shop. In short, they lost confidence in the stability of their currency (remember the ongoing theme about the importance of stable institutions) and the economy suffered. In 1994 the government decided to do something radical, and effectively "jump off a bridge" with its currency. They just up and invented a new kind of money that was strictly regulated and [initially] pegged to the US dollar. I'm oversimplifying, what's now a classic macroeconomic case study, but there's a great This American Life episode on it, that really brings it to life. Ok, but what does that have to do with China and paying more for a cab ride? Well, Brazil mainly exports things like transportation equipment, iron ore, soy beans, all of which are typically in heavy demand by their #1 trade partner, China (17% of exports). Unless you've been spending a lot of time in your bunker lately, you've probably heard that the Chinese economy has started to slow from its breakneck growth rate (check out Robert Feenstra's virtual EconED talk on 4/1 to hear why). As their economy slows, they buy less goods from Brazil, which in turn decreases the amount of revenue the government takes in through taxes. There are a lot of reasons why inflation can occur, and I won't pretend to know exactly why, but a couple of likely culprits are several tax hikes the Brazilian government instituted last year, as well as simply printing more currency to make up for the deficit. Paul Krugman​ talks about something similar with his  "stagnation" talk given at EconED 2014. Brazil's highest inflation in 12 years: Enough about inflation, one weird side note before I go: Volkswagen is the best known car brand in Brazil. They have 4 factories here and stopped manufacturing classics like the original "Beetle" and the "Microbus" 10 years after the rest of the world had stopped making them. You still see them all over the place and they seem to be the vehicle of choice for roadside vendors. Between the crazy street art and all the VW busses, Brazil might be the place for you if you're an aging hippie: Ok, on to a new continent. See you in 'Joburg. ... View more

In a plenary session on the first full day of events at SXSWedu, Temple Grandin, Professor of Animal Science at Colorado State University, focused participants on meeting the needs of every learner we touch.  The crowd cheered when she encouraged us to understand that people think differently and we need to bridge the gap between the field and academics.  “A lot of my work has been observation. Observation is a part of science.”  She went on to say, “When I learned how my visual thinking was different from verbal thinking, it gave me insight into how different people’s brains approach problem solving. If I don’t have a picture, I don’t have a thought.”  Drawing from her observations in the field, she cited her exposure to different experiences that created opportunities that some labeled students aren’t getting to. "How did I find my passion? I was exposed to it."  She showed real concern for obstacles education creates for students, like a student who was denied taking a biology class that she really wanted to take because she wasn’t able to first pass her algebra class.  The talk really left me thinking—what are we trying to accomplish in the economics classroom?  Are we preparing materials for different kinds of thinkers as we create our lessons?  Are there enough visuals to encourage the visual learners and enough content to support the language-based thinkers?  And, are we exposing students to enough economics to get them interested in the field?    ...

I'm a bit behind because Brazil was such a fast paced tour. We've got a bit more time in South Africa now, so hopefully I can catch up (technically I'm still writing about Brazil while I'm in Africa). Sao Paulo is certainly not Rio, we didn't see any "City of God" type slums, but that isn't to say it's a completely rosie picture. With cities its size, there's always going to be nice areas and some not so nice areas. One of the unique things about Sao Paulo is its graffiti, or a better term would perhaps be "street art." I think it's fair to say that it's a common form of expression in the lower income areas of the city we visited; some of it was satirical, some overtly political, some of it was simply "tagging" (just a publicly spray painted symbol or word denoting the tagger), but much of it was absolutely beautiful. One of the reasons we visited Sao Paulo is "Beco do Batman." or, Batman alley. One of the things the municipal government there has done is to commission accomplished street artists to paint the walls of this particular alley. This is so the alley will draw tourists, tourists will spend money in that area of the city, which in turn will spur economic growth and raise the living conditions for those living in that area of the city. It's a classic example of aggregate expenditure and the multiplier effect, and it will appear as an example of such in Eric Chiang​'s new upcoming 4th edition of Economics: Principles for a Changing World.  Bruce Wayne lives here: Just a few examples of the graffiti. I'll post the rest later: This is from Space Invader, a world-famous street artist who works in mosaics: Finally, the government spending might have worked too well: evidence of gentrification in this developers' notice: ...

As I've mentioned the main reason why Eric Chiang​ and I are on this adventure is to turn much of the material and experiences we're gathering into a new feature (Around the World) for his upcoming book, Economics: Principles for a Changing World 4e. At this point, I want to turn to turn to some economic issues that we've already planned on including in the book (I can say this with authority now that I'm the editor ). Bet you didn't know that Brazil has the largest population of people of Japanese descent outside of Japan - approximately 1.5 million. Just a weird fact? 'Course not. We're all about economics here. The reason why has everything to do with labor and our old pal, coffee. Check out this Japanese daruma doll our cab driver from the airport had on his dashboard: Back in the early 1900's, Brazil's main export was, you guessed it- coffee. At that time coffee was just starting to become extremely popular and its demand was increasing exponentially. Brazil needed labor to work its coffee plantations. This is around the same time that fuedalism in Japan formally ended, and all of the sudden a major labor force was looking for work. In 1907 Brazil and Japan signed a formal immigration treaty, and when both World Wars curtailed any european labor available for the coffee plantations, the Japanese immigration numbers boomed: That's just part of the story though, notice how immigration numbers fall off in the 60's. This is because Japan's economy took off after the US occupation ended and there was no longer an incentive for the Japanese labor force to emigrate. One of the unique things about the Japanese population in Japan is the depth to which they've been assimilated into the culture here (some would argue forceably). Much of the population is 4th or 5th generation by this point, no longer speaks Japanese, and identifies as Brazilian (though as you'll see, there are still many cultural markers of their heritage. Today, we trekked out to the Liberdade area of São Paulo, where much of this group is concentrated, to witness the first hand effects of a shift in the labor market: Up next, graffiti, inflation, and then South Africa! ...
