In the short run, a firm cannot vary its capital, K=2, but it can vary its labor, L. It produces output, q. You are given two production functions. (a) q = 10L + K MPL = 10 (b) q = L0.5K0.5 For each production function, please determine whether the production function will show diminishing marginal product (diminishing marginal returns) as labor increases. You must give an explanation for each answer. (Note: Diminishing returns of labor refer to the decrease in marginal product of labor as the quantity of labor increases).
Homework Study Question 4 - Long Answer Please help me with PART B I understand part A and have already answered it, but part b im not getting! Our closed economy has a production function Y = A•F(K,LxE), where Y, K, L, E & A all have their usual meanings as per our lectures & course textbook. Also, this production function exhibits all the usual mathematical/economic properties we usually assume: positive marginal products, diminishing marginal products, complementarity between K & (LxE), and constant returns to scale. The aggregate consumption function depends negatively on the real interest rate, the government budget is balanced initially & the economy is in both a long-run equilibrium and steady state initially. The population growth rate is 2% per year, capital depreciates at a rate of 3% per year, the saving rate is 25% and technology is constant. Suppose the level of labour effectiveness (E) suddenly permanently rises by 10%. Use the long-run classical model…
