Market Equilibrium and the Effect of Market Interventions

MobLab Game: Competitive Market

Key Teaching Points:

  • Experience the “invisible hand” of the market; individual profit maximization leads to competitive-market equilibrium.
  • Show that the competitive-market equilibrium maximizes total surplus (absent external costs or benefits).
  • Explore the equilibrium effects of either supply or demand shifts.
  • Demonstrate the equilibrium and surplus effects of common government interventions: per-unit taxes and subsidies, price ceilings and floors.

Utility Maximization

MobLab Game: Consumer Choice: Cobb-Douglas

Key Teaching Points:

  • When allocating a fixed budget, sequentially choosing the item offering the highest marginal utility per dollar will generally lead to the utility-maximizing budget allocation.
  • Students will gain familiarity with some of the implications of the Cobb Douglas utility function, including the result that an item’s optimal budget share is equal the ratio of its exponent to the sum of all exponents.
  • A monotonic transformation of a utility function does not affect the utility-maximizing consumption bundle.

    Utility Maximization

    MobLab Game: Consumer Choice: Cobb-Douglas

    Key Teaching Points:

    • When allocating a fixed budget, sequentially choosing the item offering the highest marginal utility per dollar will generally lead to the utility-maximizing budget allocation.
    • Students will gain familiarity with some of the implications of the Cobb Douglas utility function, including the result that an item’s optimal budget share is equal the ratio of its exponent to the sum of all exponents.
    • A monotonic transformation of a utility function does not affect the utility-maximizing consumption bundle.

    MobLab Game: Bertrand

    Key Teaching Points:

    • When selling an undifferentiated product without capacity constraints, firms have strong short-run incentives to engage in vigorous price competition.
    • Marginal-cost pricing may arise in markets with as few as two firms.
    • Use of Bertrand Competition allows instructor to focus on factors facilitating collusion in repeat interactions.

    MobLab Game: Stakelberg

    Key Teaching Points:

    Public Goods

    MobLab Game: Public Good: Linear

    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.

    MobLab Game: Public Good: Punishment and Reward

    Key Teaching Points:

    • Some will pay a cost to punish free riders or to reward contributors, resulting in increased voluntary contributions.
    • Reporting each individual’s contribution likely increases voluntary contributions to a public good

    MobLab Game: Public Good: (Discrete) Threshold

    Key Teaching Points:

    • Highlights the features of public goods: non-rival and non-excludable.
    • Highlights the coordination aspect of the free-rider problem.
    • Allow players to explore the collective action problem, where more diffuse benefits lead to lower overall contributions.

    Public Choice

    MobLab Game: R&D Race (All Pay English) and R&D Race (All Pay Sealed Bid)

    Key Teaching Points:

    • Explore how rent-seeking behavior emerges in all pay auctions.

    MobLab Game: Multilateral Bargaining

    Key Teaching Points:

    • The importance of organizing coalitions.
    • Explore how majority rule may lead to unequal distribution of resources.

    MobLab Game: Two-Candidate Election

    Key Teaching Points:

    • Explain clustering by political candidates and retailers.
    • Develop the Median Voter Theorem and predictions.
    • Polling-data option allows exploration of policy changes due to new information.

    Asymmetric Information

    MobLab Game: Market for Lemons

    Key Teaching Points:

    • Experience in an environment with asymmetric information.
    • Demonstrates how asymmetric information may lead to adverse selection and market failure.

    Externalities

    MobLab Game: Externalities (Judge Me Not)

    Key Teaching Points:

    • Why profit maximization may “force” individual firms to choose polluting technologies.
    • Highlights the tension between what is good for the individual and what is good for society.
    • Explore what is an “optimal” level of pollution.

    MobLab Game: Externalities with Policy Interventions

    Key Teaching Points:

    • Market failure in a competitive market for an externality-generating good.
    • For a negative externality, reducing transactions via a tax or tradable permit may increase surplus.
    • By increasing transactions, a subsidy corrects a positive externality.

    Decision Making Under Uncertainty

    MobLab Game: Bomb Risk Game

    Key Teaching Points:

    • Individuals differ in their risk tolerance. Risk preferences displayed in one environment can carry over to other environments.
    • Individuals who open fewer than 50 boxes can be said to be risk averse. Those who open more can be said to be risk seeking.

    Additional Risk Preference Surveys: Risk Preferences: Holt Laury and Risk Preferences: Binswanger/ Eckel and Grossman

    Auctions and Incentive Compatibility

    MobLab Game: Common-Value English

    Key Teaching Points:

    Game Theory: Mixed Strategy Equilibria

    MobLab Game: Rock, Paper, Scissors

    Key Teaching Points:

    • While all games with a finite number of actions have a Nash equilibrium, not all games have an equilibrium in pure strategies. These games will have a mixed-strategy equilibrium.
    • In a mixed-strategy equilibrium, each player chooses the action mixture making the other player indifferent between the actions she (probabilistically) plays in equilibrium. Indifferent between these actions, a player is willing to play the mixture necessary to make the other indifferent.
