Question 1

Marginal profit is the slope of the total profit curve.

Accepted Answer

A) True 
 B)False  True

Question 2

If a firm's fixed cost (overhead) increases, what happens to its profit-maximizing price and output?

Accepted Answer

Nothing.Whatever output was most profitable before the increase in fixed costs must still be most profitable because total profit is reduced by the same amount at each and every output level and marginal cost has not changed.

Accepted Answer

A) True 
 B)False  True

Question 4

Accepted Answer

A) True 
 B)False

B)  producers use both technical and financial information.
C)  the demand curve consists of price and quantity pairs.
D)  the average cost curve has only one low point.

Accepted Answer

A)  increase output until marginal profit equals zero.
B)  reduce output until marginal profit equals zero.

Exam 8: Output, Price, and Profit: the Importance of Marginal Analysis

Marginal profit is the slope of the total profit curve.

If a firm's fixed cost (overhead) increases, what happens to its profit-maximizing price and output?

If marginal cost of an additional unit of output is greater than average cost, then average cost will rise.

Economists assume that business firms have many goals, and profit maximization is just one of them.
