other things equal.

When producers do not have to pay the full cost of producing a product, they tend to

overproduce the product because of a supply-side market failure.

It is the custom for paper mills located alongside the Layzee River to discharge waste products into the river. As a result, operators of hydroelectric power-generating plants downstream along the river find that they must clean up the river's water before it flows through their equipment. In the situation described above, we would expect an

overproduction of paper in the mills.

consumer sovereignty

If the market price of a product increases, then the total

consumer surplus will decrease.

The difference between the maximum price a consumer is willing to pay for a product and the actual price the consumer pays is called

consumer surplus.

An increase in the price of a product will reduce the amount of it purchased because

consumers will substitute other products for the one whose price has risen.

"Under central planning, some group has to decide how to get the necessary inputs produced in the right amounts and delivered to the right places at the right time. This is a nearly impossible task without markets and profits." This quotation best identifies the

if all the resources of an economy are in use, more of one good can be produced only if less of another good is produced.

Suppose that an individual sees a tremendous opportunity to produce and sell a new product but dismisses the idea because there is no way to exploit this opportunity for personal gain. This situation best identifies the

incentive problem under communist central planning.

Refer to the diagram, which shows demand and supply conditions in the competitive market for product X. Other things equal, a shift of the supply curve from S0 to S1 might be caused by a(n)

increase in the wage rates paid to laborers employed in the production of X.

Consumers spend their incomes to get the maximum benefit or satisfaction from the goods and services they purchase. This is a reflection of

purposeful behavior.

From society's point of view, the economic function of profits and losses is to

reallocate resources from less-desired to more-desired uses.

Suppose that tacos and pizza are substitutes, and that soda and pizza are complements. We would expect an increase in the price of pizza to

reduce the demand for soda and increase the demand for tacos.

Market failures

result in overproduction or underproduction of a good

Specialization in production is important primarily because it

results in greater total output.

Assume a drought in the Great Plains reduces the supply of wheat. Noting that wheat is a basic ingredient in the production of bread, and potatoes are a consumer substitute for bread, we would expect the price of wheat to

rise, the supply of bread to decrease, and the demand for potatoes to increase.

Macroeconomics approaches the study of economics from the viewpoint of

the entire economy.

Steve went to his favorite hamburger restaurant with $3, expecting to buy a $2 hamburger and a $1 soda. When he arrived, he discovered that hamburgers were on sale for $1 each, so Steve bought two hamburgers and a soda. Steve's response to the decrease in the price of hamburgers is best explained by

the income effect.

According to the concept of diminishing marginal utility, consumers will purchase more of a good when the price falls because

the marginal benefit of additional units of the good now outweigh the marginal cost.

A production possibilities curve shows

the maximum amounts of two goods that can be produced, assuming the full use of available resources.
