The production function in a closed economy is Y = A(5N - 0.0025N 2 ) where A is productivity. With this production function, the marginal product of labor is MPN = 6A - 0.006*A*N Suppose that A=2. The labor supply curve is N S = 60 + 10(1 - t)w where N S is the amount of labor supplied, w is the real wage, and t = 0.5 is the tax rate on wage income. Desired consumption and investment are C d = 400 + 0.8(Y - T) – 200r I d = 288.5 - 250r Taxes and government purchases are T = 20 + 0.5Y G = 50 Money demand is M d /P = 0.6Y - 260(r + π e ) The expected rate of inflation, π e , is 0.03 and the nominal money supply M is 9750. a. Solve for the real wage and the level of employment, N that clears the labor market. Then draw a graph of the labor market. Show labor supply, labor demand and equilibrium.

Then draw a graph of the production function. Show the general shape of the production function, label the axis, the curve, and the equilibrium values of Y and N. c. Use the value for Y that you found in part (b) to construct the desired savings formula as a function of r. d. Solve for the goods market equilibrium: what are the equilibrium values of r and investment? Graph the goods market equilibrium. Show and label the desired investment and desired savings curves.
