Trading with comparative and absolute advantage (cooperative learning, experiment) Students are separated into groups, representing different countries, and given worksheets with production information. One country has an absolute advantage in both goods. Groups choose resource allocations to maximize utility and then can trade with the other country. 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. There are many variations of this available (for example, see here, and here)   ... View more

Double-oral auction (experiment) The grand-daddy of economics experiments! Students are assigned roles as buyers and sellers, and trade in a simulated market. There are many, many variations of this activity (see, for example, here or here). Extensions can include shifting supply or demand, imposing price controls, taxes, or trade barriers. For very large classes, this activity may be best done using online tools, such as Veconlab or Moblab ... View more

Feeding students candy (experiment) Have students rate their happiness (utility) as they consume more and more chocolate. For larger classes, can be done with a sub-set of students as a demonstration for the rest of the class. Have students predict what will happen between rounds. here are many ways to vary this activity with different goods (e.g., have students consume marshmallows instead of chocolate).   ... View more

Deriving a demand curve (experiment) Instructor asks the class how many students would be willing to pay various prices for a specific good. Results are tabulated into a demand curve. Extensions include changing the conditions to shift the curve (e.g., would demand for a cold soda change if the day were hotter/colder). or larger classes, can be done with a sub-set of students as a demonstration for the rest of the class, or results can be collected with clickers. Salemi, Jee 2009, describes similar activity but asks students to name their price (i.e., runs an auction) for a unique good, rather than naming price and tabulating quantity. This focuses attention on reservation prices.   ... View more

Demand for champagne (context-rich problem) Students must analyze a situation in which a newspaper article confuses movements along the demand curve with shifts in the curve. For larger classes, could be done with a sub-set of students as a demonstration for the rest of the class. Follow-up questions for a representative graph could be asked using clickers.   ...

Deriving a supply curve (experiment, demonstration) Instructor asks students the minimum price they would accept in order to shave their head. Alternatively, instructor could name prices and ask class how many students would be willing to shave their head at each price. Either way, results are tabulated into a supply curve. For larger classes, can be done with a sub-set of students as a demonstration for the rest of the class, or results can be collected with clickers. ... View more

Many people do not realize that Hawaii is the world's largest producer of farmed shrimp. In 2014, shrimp was Hawaii's largest export (and not pineapples as commonly assumed). Much of this shrimp goes to Asia, where some end up in factories where low-wage laborers peel and process the shrimp. This has led to some debate regarding the fate of laborers (some of whom were enslaved) to process seafood that is eventually exported back to the United States. This is a good topic to discuss when covering international trade, production, and labor markets.

Asymmetric Information, Bargaining, and Comparative Advantage in Trade Relationships Southern Economic Journal Vol. 74 No. 2 (October 2007) by Eric Chiang Description of Game The concept of comparative advantage is a fundamental tool in economics. Yet, it is a concept that new students of economics frequently find challenging to grasp. In this interactive classroom game, three essential lessons of comparative advantage are emphasized: 1) individuals can have a comparative advantage (and thus benefit from specialization) in an activity despite not having an absolute advantage, 2) the gains from specialization are greatest when individuals have the most heterogeneous skill sets, and 3) the extent of each individual’s share of the gains from specialization is often left to negotiation, with asymmetric information playing an influential role. This classroom game allows each player to possess a unique production function, thus better resembling the diverse pool of potential trade partners that characterizes real-life trade.     ...
