Interest Rates and Monetary Policy
A. Short-Answer, Essays, and Problems
1. What is the goal of monetary policy?
2. What are the two reasons that people want to hold money? In other words, what are the two types of demand for
money?
3. Explain how the GDP and the interest rate are related to the transactions demand and asset demand for money.
4. What are the two types of demand that make up total demand for money?
5. The total demand for money is equal to the transactions demand plus the asset demand for money.
