Market Efficiency: A Recap n Market efficiency occurs when individuals know the true opportunity cost of their actions. n The “invisible hand” of the marketplace helps to maximize total benefits to society. . . but market failures can still happen.

Market Failure n Market failure: an example No government regulation against pollution n A town with clean air n A steel mill opens and emits smoke that causes: n § more respiratory diseases § dirtier clothes, houses, cars, etc.

Market Failure n Market failure: an example Steel mill doesn’t pay for clean air n Costs of production have “spilled over” to the residents (third parties) n Lower production cost n More steel is produced than would otherwise be the case

Market Failure n When a market outcome affects parties other than the buyers and sellers in the market, side -effects are created called externalities. Externalities: the impact of one person’s actions on the well-being of a bystander. n Externalities cause markets to be inefficient, and thus fail.

Negative Externalities n The uncompensated costs that are imposed upon individuals who are not directly involved in the production or consumption of goods. äThe act of producing or consuming goods sometimes generates costs to those who are not paid for them. n Automobile exhaust n Cigarette smoking

Negative Externalities in Production o A negative externality like pollution results in a new supply curve. äThe cost to society is larger than the cost to the producer. äThe social cost includes the private costs plus the costs to those bystanders adversely affected by the pollution.

Externalities and Market Inefficiency o Positive externalities in production or consumption lead to market failure. äThe market produces a smaller quantity than is socially desirable. äThe social costs of production are less than the private cost to producers and consumers.
