关于微观经济的计算题...
Consider the following information about bread production at Beth's Bakery:
Worker Marginal Product
1 5
2 7
3 10
4 11
5 8
6 6
7 4
Beth pays all her workers the same wage and labour is her only variable cost.From this information we can conclude that Beth's marginal cost
1) declines as output increases from 0 to 11,but increases after that.
2) declines as output increases from 0 to 33,but increases after that.
3) increases as output increases from 0 to 11,but declines after that.
4) continually increases as output rises.
下一道...
Assume a certain firm is producing 1,000 units of output (so Q = 1,000).At Q = 1,000,the firm's marginal cost equals $15 and its average total cost equals $11.The firm sells its output for $12 per unit.
Refer to Scenario 14-2.At Q = 999,the firm's profit amounts to
1) $993.
2) $1,007.
3) $997.
4) $1,003.
thx!
第一道正确答案是3...是declines as output increases from 0 to 33,but increases after that.但是我不明白为什么...
关于第2个 它说 refer to scenario 14-2,所谓的这个scenario 14-2 就是上面的叙述...就是这个:
Scenario 14-2
Assume a certain firm is producing 1,000 units of output (so Q = 1,000).At Q = 1,000,the firm's marginal cost equals $15 and its average total cost equals $11.The firm sells its output for $12 per unit.
Thanks so much for your explainations!but,
Um...still have questions though...
I mean,for the 1st one,why did you add the marginal product together?so you meant that those numbers are the total production?there's formula for that or?
and for the second question,
Why did you do this in this way?just need a bit of explaination...
Thx so much!
