一家企业的固定生产成本为5000美元,边际生产成本为常数,为500美元/单位产品。
(1)企业的总成本函数是什么?平均成本呢?
(2)如果企业想使其平均总成本最低,它应该选择非常大的产量还是比较小的产量?解释你的结论。
A firm has a fixed production cost of $ 5000 and a constant marginal cost of production of S 500 per unit produced.
a. What is the firm' s total cost function? Average cost?
b. If the firm wanted to minimize the average total cost,would it choose to be very large or very small? Explain.
(1)计算该生产函数下劳动的平均产量和边际产量;
(2)该生产函数是否显示了劳动的边际报酬递减,请解释;
(3)请直观地解释劳动边际产量为负的原因?
Suppose a chair manufacturer is producing in the short run (with its existing plant and equipment). The manufacturer has observed the fallowing levels of production corresponding to different numbers of workers:
a. Calculable the marginal and average product of labor for this production function.
b. Does this production function exhibit diminishing returns to labor? Explain.
e. Explain intuitively what might cause the marginal product of labor to become negative,
(1)找出利润最大化时的L数量。
(2)找出利润最大化时的q数量。
(3)最大化利润是多少?
(4)假设现在每单位的产出要征税30美元,而每小时的劳动能得到15美元的补助。并且假设企业是价格接受者,所以产品价格保持150美元不变。找出新的利润最大化的L、q和利润。
(5)假设企业要为利润支付20%的税额。找出新的利润最大化的L、q和利润。
A firm uses a single input, labor, to produce output q according to the production function q =8√L. The commodity sells for S 150 per unit and the wage rule is $ 75 per hour.
a. Find the profit - maximizing quantity of L.
b. Find the profit - maximizing quantity of q.
c. What is the maximum profit?
d. Suppose now that the firm is taxed $ 30 per unit of output and that the wage rate is subsidized at a rate of $ 15 per hour. Assume that the firm is a price taker, so the price of the product remains at $ 150. Find the new profit - maximizing levels of L, q, and profit.
e. Now suppose that the firm is required to pay a 20 percent lax on its profit. Find the new profit - maximizing levels of L, q, and profit.
