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 – 2T + 3NX – 200r. The function for NX is NX = 200 – 100e, where e is the exchange rate. The price level (P) is fixed at 1.0. The international interest rate is r * = 2.5 percent.
Using the LM curve, find the equilibrium level of Y in the small open economy, if M = 100
My question is,how do i find the equilibrium Y given that I don't have the values of G and T?
