第十章 Technology：Understand the concepts of technology. Understand the propertied of technology and returns to scale.10.1Technologies:Technologies[判断题]The production set of a firm is the set of all products the firm can produce.选项:[错, 对]
10.2Properties of technology:Properties of technology
10.3Returns to scale:Returns to scale
[判断题]A production isoquant is a locus of combinations of inputs that are equally profitable.选项:[错, 对]
[单选题]If a firm moves from one point on a production isoquant to another point on the same isoquant, which of the following will certainly NOT happen?选项:[a change in the rate of technical substitution, a change in the level of output, a change in the ratio in which the inputs are combined, a change in the marginal products of the inputs]
[单选题]In any production process, the marginal product of labor equals:选项:[the change in output per unit change in labor input for 'small' changes in the amount of input., total output divided by total labor inputs., total output produced with the given labor inputs., the value of total output minus the cost of the fixed capital stock.]
[判断题]The production function f (x,y) = x + y has constant returns to scale选项:[错, 对]
[单选题]The production function Q = 50K0.75L0.75 exhibits选项:[increasing returns to scale., decreasing returns to scale., constant returns to scale., increasing, then diminishing returns to scale.]
[单选题]A firm has a production function f (x,y)=1:10(x0.20 + y0.20)5 whenever x > 0 and y > 0.选项:[increasing returns to scale if x + y > 1 and decreasing returns to scale otherwise., constant returns to scale., decreasing returns to scale., increasing returns to scale.]
[单选题]( ) means the relationship between the inputs employed by a firm and the max output it can produce with those inputs.-Technology is process to turn in to out production function represents firms technology选项:[Average total cost, Graphing production, constant returns to scale, Production function]
[判断题]At some pint adding more of a variable input, such as labor, to the same amount of a fixed input, such as capital, will cause the marginal product of the variable input to decline--MPL could become negative if workers got in each other's way but no firm would hire to this point选项:[对, 错]
[单选题]Does ( ) decline eventually as the number of workers increases选项:[average fixed cost, Minimum efficient scale, total cost, MPL]
