You are considering the choice between investing $50,000 in a conventional one-year bank GIC offering an interest rate of 5 percent and a one-year inflation-plus GIC offering 1.5 percent per year plus the rate of inflation.

Which is the safer investment?

Which offers the higher expected return?

If you expect the rate of inflation to be 3 percent over the next year, which is the better invest- ment? Why?

If we observe a risk-free nominal interest rate of 5 percent per year and a risk-free real rate of 1.5 percent, can we infer that the markets expected rate of inflation is 3.5 percent per year?
