QUESTION 12

  1. Consider the worksheet table showing the four economic indicators for the 1960’s. Choose the paragraph that best describes the data for your whole decade.
  2. a.The decade saw an unstable economy. In several years output grew rapidly, but there was a recession at the decade’s beginning and a severe recession in the middle. Unemployment dropped early in the decade, then soared to high rates during the recession. Lenders became very pessimistic during the mid-decade recession, so riskier corporations had trouble borrowing. And, to top it all off, the decade saw the highest inflation of the past fifty years. There were some years when inflation and unemployment were both above average, the worst of all possible worlds.
  3. b.The decade saw one of the longest expansions in U.S. history. After a mild recession at the start, output grew steadily, at above average rates towards the end of the decade. Unemployment peaked early, then declined to low levels by the end of the decade. In the money market lenders were confident through most of the decade, after a bit of trouble early. Inflation was troublesome early in the decade. Remarkably, though, despite steady growth and falling unemployment, inflation declined and remained below average during most of the decade.
  4. c.The decade saw one of the longest expansions in U.S. history. After a mild recession at the beginning of the decade, output grew steadily, often rapidly. Unemployment rates declined to very low levels by the end of the decade. The money market was settled, as lenders remained confident throughout the decade. All was not as well as it seemed, though. Inflation was under control at the beginning of the decade. After a steady rise, by the end of the decade it had become a problem.
  5. d.The decade began with the worst recession since the Great Depression. Output fell substantially and unemployment rose to the highest levels in decades. Inflation was high as well, the worst of all possible worlds. Money markets became severely pessimistic with the downturn, and lenders remained gloomy throughout most of the decade.  The recovery saw rapid growth at first, but the unemployment rate fell to acceptable levels only by decade’s end. The recession helped bring down inflation, though, to very low levels by mid-decade. Inflation crept up again by the decade’s end, however.

QUESTION 13

  1. Now use the 1960’s data table and apply our macroeconomic model to analyze the data for 1964 to 1968.  
  2. •         Assume that Q on the horizontal axis of the goods market represents real GDP.
  3. •         Assume that changes in P on the vertical axis of the goods market represent changes in the inflation rate (so a fall in P represents a decrease of the inflation rate).  
  4. •         Assume that unemployment is represented by the difference between equilibrium output and potential output, and that the unemployment rate at potential is 5%.
  5. •         Assume that changes in r on the vertical axis of the money market represent changes in the interest rate spread (so a rise in r means a bigger spread). Changes of less than 0.1% are not important.
  6. •         When in doubt, compare the first year to the last year, and ignore the years between. That identifies the trend of the whole period.
  7. Which shift best describes this time period in the goods market during 1964 to 1968?
  8. a.Aggregate supply was increasing.
  9. b.Aggregate supply was decreasing.
  10. c.Aggregate demand was increasing.
  11. d.Aggregate demand was decreasing.

  1. What counter-cyclical monetary policy should the Federal Reserve have followed during this period, in order to stabilize the economy at potential output during 1964 to 1968?
  2. a.There was no clear counter-cyclical monetary policy, because output rose above potential but the inflation rate was falling.
  3. b.Increase the money supply to decrease the real interest rate, and so increase aggregate demand.
  4. c.There was no clear counter-cyclical monetary policy, because output fell below potential but the inflation rate was rising.
  5. d.Decrease the money supply to increase the real interest rate, and so decrease aggregate demand.

QUESTION 16

  1. Choose a “story” that best matches the data and the analysis from the model for the years 1964 to 1968. (The names of wars and policymakers have been removed so as not to give away the answer to those who know U.S. history.)
  2. a.The effects of a severe recession early in the decade were still being felt at the beginning of this period. Output was less than potential, and financial markets remained pessimistic. As financial markets gained confidence, however, borrowing costs fell for more-risky businesses, which increased investment spending. Tax cuts for households added to consumer spending, and the government increased spending on military purchases.
  3. b.At the beginning of this period the economy was expanding and output approached potential. Then a war helped cause large increases in oil prices, which increased business costs. Businesses cut back on production and passed higher costs to consumers in higher prices, as much as they could. High inflation increased money demand, and financial markets became pessimistic, which further contributed to the economy’s problems.
  4. c.The effects of recession early in the decade had faded by the beginning of this period. Rapid technological advance helped cause steady growth in output. These new technologies along with falling oil prices caused inflation to decrease, even though output rose above potential. Financial markets were optimistic throughout this period. They increased lending enough to hold interest rates stable despite rising incomes.
  5. d.At the beginning of this period the U.S. President decided to expand Federal social spending and fight a war against U.S. enemies at the same time. A large tax reduction that had been proposed by a previous President took effect. After that, consumer and government spending increased rapidly. Financial markets were generally optimistic, but increasing demand for money raised borrowing costs, especially for more-risky businesses.
