1.Suppose that declining resource supplies reduce potential output in each period by 4%. What kind of monetary policy would be needed to maintain a zero rate of inflation at full employment?

2.The Humphrey-Hawkins Act of 1978 required that the federal government maintain an unemployment rate of 4% and hold the inflation rate to less than 3%. What does the inflation-unemployment relationship tell you about achieving such goals?

3.The natural unemployment rate in the United States has varied over the last 50 years. According to the Congressional Budget Office, the natural rate was 5.5% in 1960, rose to about 6.5% in the 1970s, and had declined to about 4.8% by 2000. What do you think might have caused this variation?
