What is the product they are talking about？

The marginal product of labor in the production of computer chips is 50 chips per hour. 'The marginal rate of technical substitution of hours of labor for hours of machine-capital is 1/4. What is the marginal product of capital？

Do the following functions exhibit increasing, constant, or decreasing returns to scale？ What happens to the marginal product of each individual factor as that factor is increased and the other factor held constant？

Suppose that labor is the only variable input to the production process. If the marginal cost of production is diminishing as more units of output are produced, what can you say about the marginal product of labor？

(1)如果公司决定将两种产品的价格都提高10%，其销售量会有什么变化？销售收入呢？

(2)你能否从已知的信息中判断，哪个产品会给厂商带来最大的收入？如果答案是肯定的，为什么？如果无法做出回答，你还需要哪些信息？

The ACME Corporation determines that at current prices the demand for its computer chips has a price elasticity of-2 in the short run, while the price elasticity for its disk drives is- 1.

a. If the corporation decides to raise the price of both products by 10 percent , what will happen to its sales？ To its sales revenue？

b. Can you tell from the available information which product will generate the most revenue for the firm？ If yes, why？ If not, what additional information would you need？

对竞争性行业中的一个厂商的售价为5美元的产品征收销售税为1美元。

(1)税收是如何影响厂商的成本曲线的？

(2)厂商的价格、产出、利润会发生哪些变化？

(3)是否会有厂商进入或退出该行业？

A sales tax of S 1 per unit of output is placed on a particular firm whose product sells for $5 in a competitive industry with many firms.

a. How will this lax affect the cost curves for the firm？

b. What will happen to the firm' s price, output, and profit？

c. Will there be entry or exit in the industry？

(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.
