The table above shows the maximum possible output combinations of good X and good Y that Microland can produce by using all of its available resources and technology. As the production of good X increases, what happens to the opportunity cost of producing good X?

• It decreases, because the production of good Y decreases by greater amounts

• It decreases, because the production of good Y increases by smaller amounts

• It remains constant, because the production of good X increases by the same amount

• It increases, because the production of good Y decreases by greater amounts

• It increases, because the production of good Y increases by smaller amounts

An increase in the supply of good X resulted in an increase in the price and quantity of good Y. It can be concluded that good Y is

• an inferior good

• a luxury good

• a normal good

• a substitute for good X

• a complement for good X

Which of the following best describes how a consumer maximizes total utility from the consumption of a bundle of goods and services?

• By choosing the quantity of each good such that the quantity demanded of each good is equal to the quantity supplied

• By choosing the quantity of each good such that the marginal utility from each good is equal to zero

• By choosing the quantity of each good such that the price is equal to the marginal revenue

• By choosing the level of output where marginal revenue is equal to marginal cost

• By choosing the combination of goods such that the marginal utility per dollar spent on the last unit of each good is equal

The marginal benefit of consuming a good is

• the change in average utility that results from consuming one more unit of the good

• the same as the total benefit

• equal to the marginal cost of the good

• the change in total expenditures as a result of buying one more unit of the good

• the maximum amount a consumer is willing to pay for one more unit of the good

The economic concept of total consumer surplus refers to which of the following?

• The difference between the quantity of a good or service that people purchase and the amount that they actually consume

• The overproduction of goods and services relative to the socially optimal level of output

• The sum of the differences between the prices that consumers are willing to pay for a good or service and the price they actually pay

• The sum of the differences between the prices that consumers are willing to pay for a good or service and the minimum prices that sellers must receive to offer that quantity

• The difference between the quantity demanded and the quantity supplied of a product at a given price
