Document Summary

Factor demand and marginal revenue product in a purely competitive firm. The table shows production and input cost data for a firm buying and selling competitively. The firm uses one variable input and has fixed costs of . Complete the table and then use the information to answer the fill-in questions. 7: the firm"s marginal factor cost is , for the first unit of input marginal revenue product is and is found by. 2 multiplying __________ and __________: the firm should hire the first unit of input since the __________ is greater than the __________, for the second unit of input the mfc is and the mrp is . The firm should hire the second unit of resource since the __________ is greater than the. __________: to maximize profits the firm should hire _____ units of input and obtain profits of , suppose the firm was using 4 units of input and was considering using one more unit.

Reminders:

Q: Quantity, TC: Total Costs, VC: Variable Costs, MC: Marginal Costs, MR: Marginal Revenue, TR: Total Revenue

1. Suppose the market for DVD movies is perfectly competitive. The industry price for the movies is $24, and a typical firm has the following total cost data:

Q	TC	VC	MC	MR	TR	Net Profit
0	10
1	33
2	53
3	70
4	90
5	114
6	143

a. Calculate the TR, MR, and MC for each level of output.

b. What condition must be met for the firm to maximize profits? What is the profit maximizing level of output and price for this firm? How much profit would be made?

2. Now suppose that some firms have been able to differentiate their DVDs, and the market has become monopolistically competitive. A typical firm now has the following demand schedule and total cost data:

Q	P	TC	VC	MC	MR	TR	Net Profit
0	40	8
1	35	20
2	30	28
3	25	40
4	20	56
5	15	76
6	10	100

a. Calculate the TR, MR, and MC for each level of output.

b. What condition must be met for the firm to maximize profits? What is the profit maximizing level of output and price for this firm? How much profit would be made?

Question 1

A firm should hire workers up to the point where

Question 1 options:

	MP = P.
	MFC = P.
	MFC = MRP.
	MP = MRP.

Question 2

If the additional revenue from hiring an additional worker equals the additional costs from hiring the extra worker, then we know that

Question 2 options:

	MFC/MPP_L = wage.
	MFC/MRP_L = 1.
	MFC = MPP_L.
	MRP_L/P = MFC.

Question 3

A firm that maximizes profits also

Question 3 options:

	pays input prices lower than other firms do.
	cuts corners in production processes so that its products are made too cheaply.
	is inefficient.
	uses the least-cost combination of resources.

Question 4

The demand curve for labor slopes down because

Question 4 options:

	firms value less efficient workers less than they value more efficient workers.
	firms must lower prices to sell the additional units of its product that the extra workers produce.
	of profit maximizing behavior.
	of the law of diminishing marginal product.

Question 5

If MFC > MRP_L, the firm should

Question 5 options:

	get rid of some capital.
	reduce the number of workers.
	lower wages.
	hire more workers.

Question 6

Question 6 options:

	A decrease in labor productivity.
	A decrease in the price of automobiles.
	A decrease in the price of robots that are used to solder parts of the car together.
	An increase in the demand for automobiles.

Question 7

The marginal revenue product gives

Question 7 options:

	the additions to total cost when an additional unit of a variable input is hired.
	the additional revenue obtained when an additional unit of a variable input is hired.
	the change in total product for an additional unit of a variable input.
	the amount that other inputs must increase by when labor increase by one unit.

Question 8

The monopolist's input demand curve is the

Question 8 options:

	marginal physical product curve.
	marginal revenue product curve.
	marginal revenue curve.
	marginal factor cost.

Question 9

	the firm's demand for labor decreases.
	the wage rate the firm pays will increase.
	the firm's marginal factor cost will increase.
