Which of the following will likely occur in a small open economy with a fixed exchange rate regime under expansionary monetary policy according to the Mundell-Fleming Model?A.The currency will appreciateB.The currency will depreciateC.There will be no impact on the currency valueD.The IS* curve will shift to the right

The Mundell-Fleming Model is a model in international economics which posits that in small open economies with perfect capital mobility, monetary policy is ineffective under a fixed exchange rate regime. Here's a step-by-step explanation of what happens under expansionary monetary policy in such an economy:

1. The central bank increases the money supply. This lowers domestic interest rates.

2. Lower interest rates make domestic bonds less attractive, so investors sell these bonds and buy foreign bonds. This increases the demand for foreign currency and decreases the demand for domestic currency.

3. In a flexible exchange rate regime, this would cause the domestic currency to depreciate. However, under a fixed exchange rate regime, the central bank intervenes to prevent this from happening. It does this by buying up domestic currency and selling foreign currency.

4. This intervention keeps the exchange rate fixed but also increases the money supply further, which would lower interest rates even more. But since the exchange rate is fixed, capital simply flows out of the country until interest rates are back to their original level.

5. Therefore, the expansionary monetary policy has no effect on the economy. The IS* curve, which shows the relationship between output and interest rates for a given exchange rate, does not shift.

So, the correct answer to your question is C. There will be no impact on the currency value.

The Mundell-Fleming Model is a model in international economics which posits that in small open economies with perfect capital mobility, monetary policy is ineffective for domestic purposes. Here's how it would work under expansionary monetary policy:

1. The central bank would first increase the money supply. This would lower domestic interest rates.

2. Lower interest rates would make domestic bonds less attractive, so investors would sell their domestic bonds and buy foreign bonds. This would increase the demand for foreign currency and decrease the demand for domestic currency.

3. Under a fixed exchange rate regime, the central bank must intervene in the foreign exchange market to maintain the fixed rate. This means they would have to sell foreign currency reserves and buy domestic currency to counteract the increased demand for foreign currency.

4. However, this action would decrease the money supply, counteracting the initial increase in the money supply from the expansionary monetary policy.

5. Therefore, the net effect is that there is no change in the money supply, interest rates, or income. The IS* curve, which represents combinations of income and interest rates for which the goods market is in equilibrium, does not shift.

So, the correct answer is C. There will be no impact on the currency value.
