Widget production Students have fixed capital and must create ëwidgetsí (folded and stapled paper); labor is increased in each round. Resulting production data is used to calculate total, marginal and average production and costs.  [decreasing marginal product/increasing marginal costs] For large classes, can be done with a sub-set of students as a demonstrations for the rest of the class. There are many ways to vary this activity by varying the good produced (e.g., this variation is about making peanut-butter and jelly sandwiches).   ... View more

Why are some nations wealthy? (cooperative learning) Students work in groups to analyze macro data and predict which nations are rich and which are poor. For larger classes, can have multiple groups for each country (just have an equal number of groups for each country) and then pair up groups for trading. With larger classes, could collect individual answers with clickers.   ... View more

At the start of each school term, office supply stores tend to offer fantastic deals on school supplies. The following ad is a great example to show. Show this ad after you discuss how elasticity affects total revenue, and then ask "If school supplies are an inelastic good, why would stores discount them instead of raise prices to maximize total revenue?" This is a good way to introduce the idea that office supply stores use these ads to draw customers into the store. Indeed, some customers will buy only the school supplies on sale, which would result in a loss for the store. But as long as one out of every 5 or 10 customers who comes in buys a printer, office chair, or other higher priced item, the store would more than make up for the loss leader. I then use this example to calculate the cross-elasticity of demand for substitutes and complements. ... View more

Market efficiency is perhaps one of the most important topics in any principles course.  Yet the very related concepts of consumer and producer surplus are two of the most difficult topics for students to grasp.  They are difficult because of the high level of abstraction required from students in order to master them; in particular consumer surplus. Yet, it is critical for students to understand these concepts well if they are to understand market efficiency and deadweight loss.  So I usually have one overriding goal when teaching market efficiency to principles students: how can I make the deadweight loss concrete enough for them? The case study of the market for organs (for instance the market for human kidneys), is a great way to achieve this goal.  I usually like to begin the discussion referring to a famous article in the NYTimes describing the now famous (or infamous), auction of a human kidney on ebay. After describing the auction for students, I present the following clicker question to them: Take a guess of how much was the bidding for this auction when e-bay took it down three days after it started: a) 25K b) 100K c) 200K d) 1 million e) More than 1 million Students are always shocked to learn the auction for a kidney had reached almost 6 million in two days! From this point the discussion could go in many different and very interesting directions: Why did ebay took down the auction? Answer: as you know, it is illegal in the U.S. to sell your organs. Why does the U.S. ban the sale of organs? Answer: many possible answers. But, probably the reason has to do more with ethics than with economics.  It is interesting, though, that the sale of blood is not prohibited. Is the market for organs in this country efficient? Clearly not.  Usually the number of donors is way below the number of people waiting for an organ.  In the market for kidneys, the waiting time is about 3.5 years, which is many times longer than what the patient could wait.  The best place to get data on this market is the Organ Procurement and Transplantation Network.  They offer real time data on the demand and supply data for human organs. What is consumer and producer surplus in the market for kidneys?  What happens to producer surplus when there is no way to legally profit from selling an organ? What can we do to increase the efficiency in this market? What is the deadweight loss in this market?  How does advances in medicine change the deadweight loss in this market? The answer to this last question is what makes this case study fundamentally useful to teach this concept. In this market, deadweight loss is not an abstract idea, but it is actually human lives! ...

Hamilton's National Bank In this lesson from the Federal Reserve Bank of St. Louis, students participate in two rounds of a role play to help them understand the role of banks in facilitating economic growth through loans. Round 1 is conducted without a bank. After the first round, students read excerpts from Secretary of the Treasury Alexander Hamilton’s 1790 report to Congress in which he proposes a national bank because the United States had few banks at the time. Students then conduct Round 2 of the role play with a bank. After the round, students read excerpts from and summaries of the statute creating a national bank, Thomas Jefferson’s opposition, and Hamilton’s rebuttal. Lesson Plan and PowerPoints Included. ...

As we all know, the theory of production can be applied to any production process, regardless of whether the output is sold in the market.  For instance, many of us use the production function for course performance to study economics education.  Using a noncommercial example to present the theory of production for the first time to students have many benefits: 1) students see how economics apply to their daily lives, and 2) students see how rules of production are independent of input costs. By far the most popular example I use in my class of noncommercial production is the production function for romantic partners. Since many of my students are usually engage in that production as they take my course, they can immediately identify with the case study.  So, here is a question I use to spark the discussion. Which of the following is the most Fixed input of in your production of romantic partners? a)    your chiseled abs b)    your cool haircut c)    your nice dancing skills d)    your pick-up line The idea here is for students to see that these inputs move from more fixed (abs) to more variable (pick-up line).  But, the point is not necessarily for students to identify the “best” answer, but more to see how production works and applies to their daily life.  I usually present this as a clicker question at the beginning of the class; let students vote once, and then allow them to think-pair-share and the vote again.  If I had assigned the question before class (as one could do using a system like FlipItecon.com), I could show some sample answers from students.  This allow the instructor to get the most of out of the classroom activity. Here are some of the best I have received from students over the years. For (a): “You can change the other things pretty quickly but you have to build abs over time.” For (c): “dancing skills take long to develop”. For (d): “my abs may fade, my hair may fall out, my body may become crippled, but i can always use my wit!” This student is clearly mixing the definition of a fixed input, so this wrong answer presents an excellent teaching moment for me. And, perhaps the best one of all: “You've got the curves to supply my demand.” I encourage you to use this, or any example that allow students to see how relevant economics is to their daily lives.   ...
