1. A very small country's gross domestic product is $12 million.
a. If government expenditures amount to $7.5 million and gross private domestic investment is $5.5 million, what would be the amount of net exports of goods and services?
2. How would your answer change in Problem 1 if the gross domestic product had been $14 million?
3. Assume investors expect a 2.0 percent real rate of return over the next year. If inflation is expected to be 0.5 percent, what is the expected nominal interest rate for a one-year U.S. Treasury security?
4. A thirty-year U.S. Treasury bond has a 4.0 percent interest rate. In contrast, a ten-year Treasury bond has an interest rate of 3.7 percent. If inflation is expected to average 1.5 percentage points over both the next ten years and thirty years, determine the maturity risk premium for the thirty-year bond over the ten-year bond.
5. You are considering an investment in a one-year government debt security with a yield of 5 percent or a highly liquid corporate debt security with a yield of 6.5 percent. The expected inflation rate for the next year is expected to be 2.5 percent.

b. What would be the default risk premium on the corporate debt security?
6. A Treasury note with a maturity of four years carries a nominal rate of interest of 10 percent. In contrast, an eight-year Treasury bond has a yield of 8 percent.
a. If inflation is expected to average 7 percent over the first four years, what is the expected real rate of interest?
b. If the inflation rate is expected to be 5 percent for the first year, calculate the average annual rate of inflation for years 2 through 4.
c. If the maturity risk premium is expected to be zero between the two Treasury securities, what will be the average annual inflation rate expected over years 5 through 8?
