Suppose that the production function for a commodity is given by Q = 10√LK
Where Q is the quantity of output, L is the quantity of labor, and K is the quantity of capital. (a) Calculate Q when L=1 and K=1, and L=2 and K=2, then indicate whether this production function exhibits constant, increasing, or decreasing returns to scale. (b) Given K=1, show the change in Q if L changes from 1 to 2, and 2 to 3, and does the production function exhibit diminishing returns? If so, when does the law of diminishing returns begin to operate? Could we ever get negative returns?
