Expert Answer

Step 1

(a)

 

If the capital and the labor increased by k times. The production function can be derived as follows.

Step 2

Here, the output is multiplied with K and the labor and capital is also multiplied by K. Thus, we can say that the production function shows a constant return to scale.

Step 3

(b)

 

Suppose,

Wage and the rental rate = 2.

Production cost = 2K+2L.

 Isoquant slope = -K/L.

Isocost slop = -...
