Consider the Cobb-Douglas production function F (L, K) = (A)(L^α)(K^1/2) , where α > 0 and A > 0. 1. The Cobb-Douglas function can be either increasing, decreasing or constant returns to scale depending on the values of the exponents on L and K. Prove your answers to the following three cases. (a) For what value(s) of α is F(L,K) decreasing returns to scale? (b) For what value(s) of α is F(L,K) increasing returns to scale? (c) For what value(s)...

Suppose that a firm has the Cobb-Douglas production function Q = 12K ^ (0.75) L^ (0.25). Because this function exhibits (constant, decreasing, increasing) returns to scale, the long-run average cost curve is (upward-sloping, downward-sloping, horizontal), whereas the long-run total cost curve is upward-sloping, with (an increasing, a declining, a constant) slope. Now suppose that the firm’s production function is Q = KL. Because this function exhibits (constant, decreasing, increasing) returns to scale, the long-run average cost curve is (upward-sloping, downward-sloping,...

Which is/are incorrect about the Cobb-Douglas production function: Y equals K to the power of alpha L to the power of 1 minus alpha end exponent (0 < alpha < 1 )? All are correct it increases in both K and L the share of total income that goes to capital and labor depend on the amount of K and L it exhibits diminishing marginal returns to both K and L it is constant returns to scale
