更多“等产量曲线斜率为负，表明要素合理投入区域应是一种要素在生产中…”相关的问题
下列对边际收益递减规律的说明不正确的是()
A 假设企业其它投入要素不变，不断增加一种要素的投入量，当超过某一点时，总产量的增量将越来越小，边际产量呈递减趋势
B 原因可能在于打破了要素之间合理的比例关系
C 原因可能是这种要素被浪费
D 原因可能是由于技术水平对生产效率的限制
A.当技术水平发生变化时生产函数不会发生变化
B.研究企业短期行为的前提是各种投入要素都是可变的
C.生产函数是最大产量与投入要素之间的函数关系
D.一般假设生产要素在生产过程中不可相互替代
(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,
A.-1
B.1
C.-1/2
D.1/2
E.-2
(1)企业目前的产量为100单位，成本最小化的劳动和资本分别为20和5。在图上用等产量线和等成本线表示出来。
(2)企业想将产量扩大为140单位，如果资本在短期固定，需要多少劳动？在图形上表示出来，并计算企业新的成本。
(3)在图形上表示出企业在长期生产140单位产品的成本最小化劳动和资本投入。
(4)如果边际技术替代率为K/L,计算生产140单位产品的最优劳动和资本投入。
Suppose that a firm' s production is q= 10L1/2K1/2. The cost of a unit of labor is $ 20 and the cost of a unit of capital is $ 80. a The firm is currently production 100 unis of output and has determined that the cost - mini-mizing quantities of labor and capital are 20 and 5, respectively. Graphically illustrate this using isoquants and isocost lines.
b，The firm now wants to increase output to 140 units. If capital is fixed in the short run, how much labor will the firm require？ Illustrator this graphically and find the firms new total cost.
c. Graphically identify the cost - minimizing level of capital and labor in the long run if the firm wants to produce 140 units.
d. If the marginal rate of technical substitution is K/L, find the optimal level of capital and labor required to produce the 140 units of output.
