Economic contraction throughout the rest of the world reduces the world interest rate. Use the Mundell-Fleming model to illustrate graphically the impact of a decrease in the world interest rate on the exchange rate (e), net export (NX) and the level of output(Y) in a small open economy with:(Be sure to label: the axes, the curves, the initial equilibrium levels, the direction the curves shift & the new short-run equilibrium.)
