Learning Objective 2.3

Property rights The rights individuals or firms have to the exclusive use of their property, including the right to buy or sell it.

The Legal Basis of a Successful Market System

The Market System

Protection of Private Property

Enforcement of Contracts and Property Rights

If property rights are not well enforced, fewer goods and services will be produced. This reduces economic efficiency, leaving the economy inside its production possibilities frontier.

–Perfectly competitive market A market in which there are many buyers and sellers, all the products are identical, and there are no barriers to new sellers entering the market.

Where Prices Come From: The Interaction of Demand and Supply

•Law of demand Holding everything else constant, when the price of a product falls, the quantity demanded of the product will increase, and when the price of a product rises, the quantity demanded of the product will decrease.

Learning Objective 3.4

Consumer surplus The difference between the highest price a consumer is willing to pay and the price the consumer actually pays.Marginal benefit The additional benefit to a consumer from consuming one more unit of a good or service.

Consumer Surplus and Producer Surplus

Learning Objective 4.1

Producer surplus The difference between the lowest price a firm would have been willing to accept and the price it actually receives.

Marginal cost The additional cost to a firm of producing one more unit of a good or service.

The Efficiency of Competitive Markets

FIGURE 4-6

Economic Surplus Equals the Sum of Consumer Surplus and Producer Surplus

Economic Surplus

Learning Objective 4.2

Economic surplus The sum of consumer surplus and producer surplus.

Learning Objective 4.1

Consumer surplus measures the net benefit to consumers from participating in a market rather than the total benefit. The net benefit equals the total benefit received by consumers minus the total amount they must pay to buy the good.

Producer surplus measures the net benefit received by producers from participating in a market, or the total amount firms receive from consumers minus the cost of producing the good.

When a Market Is Not in Equilibrium There is a Deadweight Loss

Deadweight Loss

Deadweight loss The reduction in economic surplus resulting from a market not being in competitive equilibrium.

Learning Objective 4.2

The Efficiency of Competitive Markets

Economic efficiency

A market outcome in which

1)the marginal benefit to consumers of the last unit produced is equal to its marginal cost of production and

2)the sum of consumer surplus and producer surplus is at a maximum.

Learning Objective 5.1

–Private cost The cost borne by the producer of a good or service.

–Social cost The total cost of producing a good, including both the private cost and any external cost.

Externalities and Economic EfficiencyExternalities May Result in Market Failure

Market failure A situation in which the market fails to produce the efficient level of output.

What Causes Externalities?

Property rights The rights individuals or businesses have to the exclusive use of their property, including the right to buy or sell it.

Private Solutions to Externalities: The Coase Theorem

Learning Objective 5.2

The Coase Theorem

Transactions costs The costs in time and other resources that parties incur in the process of agreeing to and carrying out an exchange of goods or services.

The Problem of Transactions Costs

Coase theorem The argument of economist Ronald Coase that if transactions costs are low, private bargaining will result in an efficient solution to the problem of externalities.

Learning Objective 5.3

Pigovian taxes and subsidies Government taxes and subsidies intended to bring about an efficient level of output in the presence of externalities.

Command and Control versus Tradable Emissions Allowances
