Suppose that one worker can produce 25 cookies, two workers together can produce 75 cookies, and three workers can produce 105 cookies together. What is the marginal product of the 3rd worker?
a) 20 cookies
b) 25 cookies
c) 60 cookies
d) 30 cookies
Answer : [ D ] 30 cookies.
Formula :: Marginal product of labor =
TP /
L
= Change in Total product / Change in Labor
Calculations :
| Number of Workers | Total product | Marginal product |
| 1 | 25 | 25 |
| 2 | 75 | (75 -25)/ ( 2- 1) = 50 |
| 3 | 105 | (105 - 75) / ( 3 - 2 ) = 30 |
Marginal
product of the 3rd worker is 30 cookies.

SECTION# NAME PRINT LAST NAME, FIRST NAME Suppose 9 workers can repair 36 television sets per day. If a tenth worker is hired and the each worker repairs, on average, 4 T.V. sets per day when nine workers are hired average product must be rising because the marginal product of the tenth worker 6. total number of repaired T.V. sets increases to 39, then: a. the marginal product of the tenth worker is 3.9 T.V, sets b. is greater than...
Alison can produce 1 pair of shoes and 3 cookies in one hour, Stan can produce 3 pairs of shoes and 1 cookie in one hour. If each worker has 2 hours, which of the following points (shoes, cookies) does NOT lie on the production possibility frontier? a. (8 pairs of shoes, O cookies) b. (7 pairs of shoes, 3 cookies) c.

Suppose that a worker in Boatland can produce either 10 units of wheat or 25 units of fish per year, and a worker in Farmland can produce either 25 units of wheat or 10 units of fish per year. There are 10 workers in each country. Political pressure from the fish lobby in Farmland and from the wheat lobby in Boatland has prevented trade between the two countries on the grounds that cheap imports would kill the fish industry in...
Assume that a firm has a fixed-proportions production function, in which one unit of output is produced using one worker and two units of capital. If the firm has an extra worker, say two workers, and no more capital, it still can produce only one unit of output. Similarly, an extra unit of capital does the firm no good.a) Draw the isoquants for this production function.b) Draw the total product, average product, and marginal product of labor curves (you will...

What is the average product of the first two...
A company produces reuseable water bottles. Their technology allows one worker to produce 10 water bottles in an hour. Hiring a second worker would allow them to produce 16 total water bottles in an hour and three workers can produce 18 total water bottles. What is the marginal benefit of hiring the second worker?

This question is about specialization and trade. A.) Suppose a worker in the U.S. can produce 4 cars or 10 computers. A worker in Russia can produce 2 cars or 10 computers. Suppose that the U.S. has 100,000 workers and Russia has 200,000 workers. Draw the PPF for each country. Be sure to keep the axes on the two graphs consistent. B.) Compute absolute advantage C.) Compute comparative advantage D.) Suppose that the U.S. makes only what they have comparative...
