1. Assume that prices are sticky in the short run. Use the MM-FX model to demonstrate the effects of the following events.

c. The Swiss National Bank, which is the central bank of Switzerland, announced that it will purchase Swiss government bonds for 2 million francs next month, and permanently kept the bonds.
