某完全竞争厂商的短期成本函数为STC=0.1Q3-2Q2+15Q+10。求:
(1)当市场价格为P=55时,厂商的短期均衡产量与利润。
(2)市场价格下降为多少时厂商必需停产?
(3)厂商的短期供给函数是多少?

努力水平。工人选择他的收入减去努力以后的净工资w-e(努力的单位成本假设为1)最大化的努力水平。根据下列每种工资安排,确定努力水平和利润水平(收入减去支付的工资)。解释为什么这些不同的委托-代理关系产生不同的结果。
(1)对于e≥1, w=2;否则w=0。
(2)w=R/2。
(3)w=R-12.5。
A firm's short-run revenue is given by R= 10e-e2 , where e is the level of effort by a typical worker (all workers are assumed to be identical). A worker chooses his level of effort to maximize his wage net of effort w-e (the per-unit cost of effort is assumed to be 1). Determine the level of effort and the level of profit (revenue less wage paid) for each of the following wage arrangements.
Explain why these differing principal-agent relationships generate different outcomes.
a. w=2 for e≥1; otherwise w =0,
b. w= R/2.
c. w=R-12.5.
下表显示了一个以常数边际成本10美元生产的垄断者面临的需求曲线。
(1)计算该厂商的边际收益曲线。
(2)该厂商的利润最大化产量和价格是多少?该厂商的利润为多少?
(3)在一竞争性行业中均衡价格和数量各为多少?
(4)如果该垄断者被迫以完全竞争的均衡价格生产,社会得益是什么?结果是谁获益谁受损?
The following table shows the demand curve facing a monopolist who produces at a constant marginal cost of $ 10.
a. Calculate the firm' s marginal revenue curve.
b. What are the firm's profit - maximizing output and price? What is its profit?
c. What would the equilibrium price and quantity be in a competitive industry?
d. What would the social gain be if this monopolist were forced to produce and price at the competitive equilibrium? Who would gain and lose as a result?
A.9元
B.1.8元
C.2元
D.18元
已知生产函数Q=f(L,K)=2KL-0.5L2-0.5K2,假定厂商目前处于短期生产,且K=10。
(1)写出在短期生产中该厂商关于劳动的总产量TPL函数、劳动的平均产量APL函数和劳动的边际产量MPL函数。
(2)分别计算当劳动的总产量TPL劳动的平均产量APL和劳动的边际产量MPL各自达到极大值时的厂商的劳动投入量。
(3)什么时候APL=MPL?它的值又是多少?
