Understanding Market Structures and Economic Power Study Guide

This guide explains the fundamental economic principles behind government intervention in markets. It covers how taxes and subsidies affect market equilibrium, the concept of tax incidence and its relation to price elasticity, and the consequences of price ceilings, price floors, mandates, and quotas. Essential for understanding how government policies shape economic outcomes.

Government Intervention and Market Outcomes

Government Intervention: Taxes and Market Outcomes

Government can influence market outcomes through laws, regulations, and taxes that shape costs and benefits for buyers and sellers.

  • Taxes
  • Statutory burden
  • Economic burden
  • Tax incidence
  • Supply and demand
  • Elasticity
  • Subsidies
  • Price controls
  • Quantity regulations

Assessing the Impact of a Tax

Demonstrate the equivalence of a tax on buyers and sellers and assess the impact of tax incidence on market outcomes.

  • tax on sellers
  • tax on buyers
  • marginal costs
  • marginal benefits
  • supply curve shift
  • demand curve shift
  • market equilibrium
  • tax incidence
  • economic burden

Tax Incidence and Price Elasticity

Tax incidence is determined by the relative price elasticities of supply and demand, where the more inelastic party bears more of the economic burden.

  • tax incidence
  • economic burden
  • relative price elasticities
  • inelastic demand
  • elastic supply
  • market equilibrium
  • supply and demand curves

Impact of Government Taxes and Subsidies

Analyzing how taxes and subsidies shift supply and demand curves to determine market equilibrium, quantity changes, and economic burden based on relative price elasticities.

  • tax incidence
  • economic burden
  • subsidies
  • supply curve shifts
  • demand curve shifts
  • marginal cost
  • marginal benefit
  • price elasticity
  • market equilibrium

Price and Quantity Government Interventions

Analyze how government interventions like price ceilings, price floors, mandates, and quotas impact market equilibrium, shortages, and surpluses.

  • Price ceilings

  • Minimum wage
  • Surplus
  • Quantity regulation
  • Mandate
  • Quota
  • Binding mandate
  • Binding quota

Externalities, Market Failure, and Welfare Economics

Externalities and Market Failure

Externalities are side effects of an activity that affect bystanders, leading to market failure where private interests conflict with society's interest.

  • Negative externalities

  • Market failure
  • Marginal private cost
  • Marginal external cost
  • Marginal social cost
  • Marginal private benefit
  • Marginal external benefit
  • Marginal social benefit
  • Private interest versus society's interest

Analyzing Positive and Negative Externalities

This content analyzes how positive and negative externalities lead to market failure through overproduction or underproduction relative to the socially optimal quantity.

  • socially optimal quantity
  • marginal social benefit

  • negative externalities
  • positive externalities
  • market failure
  • overproduction
  • underproduction
  • marginal private benefit
  • marginal private cost
  • marginal external cost
  • marginal external benefit

Solving Externality Problems and Market Failure

Ways of getting others to internalize externalities include private bargaining, corrective taxes and subsidies, cap and trade, and laws, rules, and regulations.

  • Negative externalities
  • Positive externalities
  • Market failure
  • Marginal private costs
  • Marginal social costs
  • Marginal private benefits
  • Marginal social benefit
  • Internalize the externality
  • Private bargaining
  • Side payments
  • Corrective taxes
  • Corrective subsidies
  • Cap and trade
  • Quantity cap
  • Laws, rules, and regulations

Externality Problems and Nonexcludable Goods

Examine externality problems that arise when people cannot be excluded from using public goods and common resources.

  • Excludable
  • Nonexcludable
  • Rival
  • Private Goods
  • Public Goods
  • Common Resources
  • Free-rider problem
  • Tragedy of the commons

  • Ownership rights

Welfare Economics and Market Efficiency

Evaluating market efficiency and market failure through the lens of economic surplus, efficiency, and equity.

  • Positive and normative analysis
  • Efficiency and equity
  • Economic surplus
  • Economic efficiency
  • Welfare

Market Failure and Deadweight Loss

Market failure occurs when market forces of supply and demand lead to an inefficient outcome, measured by deadweight loss which represents how far economic surplus falls below the efficient outcome.

  • Market failure
  • Deadweight loss
  • Efficient quantity
  • Economic surplus
  • Market power
  • Externalities
  • Information problems
  • Irrationality
  • Government failure
  • Underproduction
  • Overproduction
  • Marginal benefit
  • Marginal cost
  • Distributional consequences
  • Ability to pay

Market Power, Profitability, and Economic Surplus

Market Structure and Degrees of Market Power

Market structure determines market power, which is the extent to which a seller can charge a higher price without losing many sales to competing businesses.

Market Power and Public Policy

Market power leads to higher prices, inefficiently smaller quantity, and larger economic profits, necessitating government policies to ensure competition thrives and minimize harm.
