Introduction to Markets

Textbook Chapter: Chapter 3

MobLab Game: Private Value Sealed Bid auction

Key Teaching Points:

  • Learn how a basic exchange happens by participating in an auction.
  • Gains from trade (i.e., consumer surplus).
  • Price discovery: the transaction price results from the bids of other buyers.

Supply and Demand in a Competitive Market

Textbook Chapter: Chapter 4

MobLab Game: Competitive Market

Key Teaching Points:

  • The “invisible hand” of the market: how individual profit maximization leads to competitive market equilibrium.
  • Price discovery: the equilibrium market-clearing price results from the valuations of different buyers and costs of different sellers.
  • Gains from trade (i.e., consumer and producer surplus).
  • Shifts in either supply or demand change equilibrium outcomes.

Monopoly Pricing

Textbook Chapter: Chapter 11

MobLab Game: Cournot (with Group Size=1)

Key Teaching Points:

  • Monopolies restrict output in order to increase price.
  • The tension between the quantity price effects of increased output.

Game Theory

Textbook Chapter: Chapter 12

MobLab Game: Prisoner’s Dilemma

Key Teaching Points:

  • Key features of games: payoff matrices, best responses and dominant strategies.
  • Identification of the Nash equilibrium.
  • The (sometimes) conflicting incentives of cooperation and self-interest.
  • Repeated play may lead to more cooperative outcomes.

Oligopoly

Textbook Chapter: Chapter 12

MobLab Game: Cournot

Key Teaching Points:

  • The underlying logic of the Cournot model: how market price is determined by aggregate output.
  • The equilibrium outcomes of Cournot competition.
  • Repeat interaction may lead to collusive behavior.

Externalities

Textbook Chapter: Chapter 15

MobLab Game: Judge Me Not

Key Teaching Points:

  • When firms do not internalize external costs, profit maximization leads to inefficiently high levels of pollution.

Asymmetric Information (Adverse Selection)

Textbook Chapter: Chapter 15

MobLab Game: Market for Lemonsrom the valuations of different buyers and costs of different sellers.

  • Gains from trade (i.e., consumer and producer surplus).
  • Shifts in either supply or demand change equilibrium outcomes.

    Asymmetric Information (Adverse Selection)

    Textbook Chapter: Chapter 15

    MobLab Game: Market for Lemons

    Key Teaching Points:

    • Experience in a market with asymmetric information.
    • Asymmetric information may lead to adverse selection and market failure.

    Public Goods

    Textbook Chapter: Chapter 15

    MobLab Game: Discrete (Threshold) Public Goods

    Key Teaching Points:

    • Highlights the features of public goods: non-rival and non-excludable.
    • Demonstrates the distinction between private and social benefits of public goods.
    • Shows how individual profit maximization leads to the free-rider problem.

    Labor Markets

    Textbook Chapter: Chapter 19

    MobLab Game: Simple Labor Market

    Key Teaching Points:

    • When a perfectly competitive market determines wages, the equilibrium wage (per unit of labor) is equal to the value of the marginal product of labor of the last worker hired.

    Money & Banking
