Suppose that a firm has the production function f(1, T2) = 271 + log.(12 + 1) (a) Does the marginal product of factor 1 increase, decrease, or stay constant as the amount of factor 1 increases? Does the marginal product of factor 2 increase, decrease, or stay constant as the amount of factor 2 increases? (b)This production function does not satisfy the definition of increasing returns to scale, constant returns to scale, or decreasing returns to scale. How can this be? Find a combination of inputs such that doubling the amount of both inputs will more than double the amount of output. Find a combination of inputs such that doubling the amount of both inputs will less than double output. EXERCISE
