  • The Apple Market: A simple trading-pit experiment
    This is a simple trading-pit experiment and is commonly used as the first encounter of students with an experiment in the classroom. It introduces the concepts of supply and the demand, as well as buyer surplus and seller profits.
  • The Fish Market: More is not always better
    This experiment explores the effects of a shift in the supply curve on price and quantity. It also introduces the notion of sunk costs.
  • A Tax in the Apple Market: Who pays the tax?
    This experiment introduces a per unit tax in the Apple Market, but with a richer distribution of types. It runs three sessions of the same market: without taxes, with an excise tax paid by sellers, and with an excise tax paid by buyers. It also helps on studying tax incidence and excess burden.
  • The Coal Market: Pollution, Pigouvian taxes and permits* [external link to Experiencing Economics]. 
    In this experiment, students experience the effects of a negative externality and observe how an appropriately chosen tax or a fixed supply of marketable pollution permits may recover efficiency.
