Suppose the market for loanable funds is described by the equations: 1 = 180 - 16r S = 8 + 24r. where I is the investment, S is the national saving and r is the real interest rate. suppose the world interest rate is 6 percent. Also suppose that the net export curve is given by NX=74-2x where x is the real exchange rate. Calculate the following: domestic investment at the world interest rate Choose... * domestic saving at the world interest rate Choose... + the equilibrium real exchange rate Choose... # net capital outflow Choose... + net exports Choose... +
