Suppose output, Y t, is produced using capital, K t, and labor, N t, according to the production function: Y t = A ⋅ ( K t α N t 1 − α + K t β N t 1 − β )where the parameters satisfy 0 < α < 1, 0 < β < 1 and A > 0.
a) (5 pts) Write the production function in “per worker” terms. That is, if we define y t = Y t N t, and k t = K t N t, write y t as a function of k t.
b) (10 pts) In the Solow model, the rental rate on capital, r t, equals the marginal product of capital (MPK). Use your answer to part (a) to find the expression for r t in terms of k t.

Consider a representative firm that produces using capital (K) and labor (N). The firm hires workers at wage w and rent capital at rental rate r. Suppose the firm has the production function: F(K, N) = K™NB with a + ß < 1 and a, ß E (0,1) ii) Set up the firm's profit maximization problems and solve for the optimal K*, L*, and 7* (profits) in terms of parameters(12 points) iii) What's the ** when a + b =...
Given the production function
, if the rental price of capital is 0.133, Y=690, and K=1,728,
what is the value of the exponent
? If A=1, and the real wage is 1.15, is this economy in a long-run
equilibrium?
I know rental price of capital equals the marginal product of
capital, but I have no idea how to solve MPK, and progresses
afterward.
Please give your solution in detail.

Acme produces anvils using labor (L) and capital (K) according to the production function Q= f(L,K)=LK with associated marginal products MPL=K, MPK =L. The price of labor is w=2 and the price of capital is r=1. Does Acme's production function for anvils exhibit increasing, constant or decreasing returns to scale? Justify your answer
