(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.
A、$390 A
B、$190 A
C、$190 F
D、$390 F
(2)写出供给曲线方程。
(3)如果价格为1000美元,厂商产量为多少?利润水平为多少?在成本曲线图上表示出你的结论。
a. Suppose that a firm's production function is q=9x1/2in the short nun, where there are fixed costs of $ 1000, and x is the variable input whose cost is S 4000 per unit. What is the total cost of producing a level o[ output q? In other words, identify the total cost function C(q)?
b. Write down the equation for the supply curve.
e. If price is $ 1000, how many units will the firm produce? What is the level of profit? Illustrate your answer on a cost - curve graph.
A、Specific tariff quota
B、Voluntary export restraint
C、tariff rate quota
D、Ad valorem tariff
A、0.000625
B、0.0025
C、0.025
D、0.05
E、0.95
a.把人均产出(y=Y/L)表示为人均资本(k=K/L)和自然失业率的函数。描述该经济的稳定状态。
b.假定政府政策的某些变化降低了自然失业率。描述这一变化随时间的推进如何影响产出。对产出的稳定状态的影响大于还是小于立即的影响?请解释。
Consider how unemployment would affect the Solow growth model. Suppose that output is produced according to the production function Y=Kα[(1-u*)L]1-α,where K is capital, L is the labor force, and u*is the natural rate of unemployment. The national saving rate is s, the labor force grows at rate n, and capital depreciates at rate δ.
a.Express output per worker (y=Y/L) as a function of capital per worker (k=K/L) and the natural rate of unemployment. Describe the steady state of this economy.
b.Suppose that some change in government policy reduces the natural rate of unemployment. Describe how this change affects output both immediately and over time. Is the steady-state effect on output larger or smaller than the immediate effect? Explain.
A、a production expense that does not vary with output.
B、a production expense that changes with the quantity of output produced.
C、equal to total cost divided by the units of output produced.
D、the amount by which a firm's cost changes if the firm produces one more unit of output.
