Consider an economy that abides by a Mundell Fleming model. Capital is imperfectly mobile, prices are perfectly sticky in the short run, and the exchange rate is fixed. Assume that the current exchange rate is at its tar- get and the current domestic interest rate is equal to the foreign interest rate. Suppose the local central bank wants to stimulate economic activity by increasing the supply of money through conventional open market oper- ations. Which of the following (domestic and foreign) policies would assist the domestic central bank in achieving its goal?

1. A foreign central bank increases the supply of its currency on the FX market (i.e.SFXrises) and domestic government spending rises.
2. Foreigners stop purchasing domestic exports (i.e.Xfalls) and domestic government spending falls.
3. The foreign price level falls. (i.e.Pffalls).
4. A foreign central bank raises its local local interest rates (i.e.rfrises).
