9. Assume that the LM curve for a small open economy with a floating exchange rate is given by Y= 200r - 200 + 2 (M / P), while the IS curve is Y = 400 + 3G -27+ 3NX -200r. The function for NX is NX = 200 - 100e, where e is the exchange rate. The price level (P) is fixed at 1. The international interest rate is * = 2.5 percent. a. Using the LM curve, find the equilibrium level of Y in the small open economy, if M = 100. b. Given this value of Y, if G = 100 and 7= 100, what must be the equilibrium value of NX? c. If this value of NX is to be achieved, what must be the equilibrium exchange rate, e
