Document Summary

We see again that governments can sometimes improve market outcomes. The answer depends on the type of the good being considered. The price of ice cream cones adjusts to balance supply and demand, and this equilibrium maximizes the sum of producer and consumer surplus. But we cannot rely on the market to prevent aluminum manufacturers from polluting the air we breathe: buyers and sellers in a market typically do not take account of the external effects of their decisions. Markets work well when the good is ice cream, but they work badly when the good is clean air. Here we discuss the characteristics of different goods with a view to seeing what types of goods we may expect markets to provide efficiently and which goods may need to be provided by the government. In thinking about the various goods in the economy, it is useful to group them according to two characteristics:

D. In reality, it is hard to provide public goods efficiently.

3 points

Question 7

A. In reality, it is very hard (if not impossible) to accurately estimate the benefits of providing a public good.

B. A. In reality, there can be overruns in the cost of providing the public good.

B. Public policies protect cows from predators and diseases.

C. Cows are privately owned (private goods), whereas many endangered species are owned by no one (common resources).

D.There is a natural ecological balance between the birth rate of cows and human consumption.

3 points

Question 10

Which of the following statements about common resources is not true?

A. Due to the free-rider problem, common resources tend to be overused.

B. Because there is rivalry in the consumption of common resources, whenever one person uses a common resource it is imposing a negative externality on others who might also want to use it.

C. There are no private solutions to the management of common resources.

D. One of the solutions that ensures that common resources are properly managed is their privatization.
