Use the open-economy IS/LM model (the Mundell-Fleming model) to predict what will happen to Y, r, I, EX, NX under a floating (flexible) exchange rate regime in a small open economy. Be sure to depict the appropriate graphs, axes labels, and curve shifts in all your answers.
a. An increase in consumer confidence about the future induces consumers to spend less and save more.
b. The “Buy American” campaign ads induce domestic consumers to purchase fewer foreign-made goods.
c. The central bank sells bonds to the public.
In the monetary small open-economy model, suppose that money supply equals 100. The money demand function takes the form Md=P(0.5Y-400r). The foreign price level P* is 1. The equilibrium output Y is 200 and the world interest rate r* is 0.2.
(a) Determine the equilibrium exchange rate.
(b) If the country adopts a flexible exchange rate regime, what will be percentage change in the equilibrium exchange rate if money supply goes up by 10%?
(c) If foreign price rises by 50%, what will be the percentage change in the equilibrium exchange rate? In this case, we assume that money supply is fixed at 100.
(d) If the country wishes to stabilize the exchange rate, what will be the new money supply if foreign price rises by 50%?

- Hi can you please help with calculations/explanations of the below :) 1. During the Great Depression, countries which had a policy of competitive devaluation (or ‘beggar thy neighbour’) increased net exports by lowering the value of their currency. Using a Mundell-Fleming model with a fixed rate, show the impact of a competitive devaluation without taking account of the output gap. (hint, the exchange rate is ‘fixed’ but only after an initial lowering of its value, which causes a positive NX shock) 2. What is the long run impact of the policy in (1) after taking account of the output gap. Prove that in the long run a competitive devaluation with a fixed rate gives the same long run result as a monetary expansion with a floating rate. What is this result called? 3.
