PLEASE CITE ALL SOURCES APA

PART A

During the period of the "Great Moderation" (the mid-1980s through the mid-2000s), discussion ofthe Keynesian expenditure multiplier had largely gone out of fashion. After all, if business cycles were largely tamed, the effects of a significant demand shock seemed irrelevant. When the Great Recession hit at the end of 2007, the expenditure multiplier became a hot topic again for discussion among macroeconomists.

  • Why does the size of the expenditure multiplier matter in the real world? Why does it matter to businesses, employees, consumers and policy makers?
  • Based on what you know about the multiplier, do you think the government took the appropriate response to the Great Recession? Was the fiscal stimulus response to the recession enough, just right, or too much? What evidence can you provide for your conclusion? Find a news article (and include the link in your response) to support your opinion.

PART B

Suppose the economy is operating at potential GDP, something like was the case for the U.S. in mid-2018. The unemployment rate has reached historic lows, suggesting that the economy is at full employment. Now suppose that due to an economic slowdown in Europe, U.S. export sales decline. Use the income-expenditure model to analyze the impact this decrease in export expenditures will have on U.S. GDP and employment. Show graphically and explain your economic reasoning. To make this more concrete, here are some specific numbers to work with. Suppose potential GDP occurs where Y = $10,000 billion. Suppose that the marginal propensity to consume is 0.75. If we assume that both taxes and imports are given then the simple expenditure multiplier formula applies. Suppose exports fall by $100 billion. Use the multiplier formula to estimate the change in GDP. Suppose further that for every one percentage point that GDP falls below potential, the unemployment rate will rise by half of one percentage point. How much then will the unemployment rate rise due to the decrease in exports? Rubc . .

Label 4 appropriately. Correctly explain the economic reasoning about what happens to GDP and employment, and most importantly, why. 4 Use the simple expenditure multiplier formula to correctly compute the change in GDP. 4 Converting the change in GDP to percent, use the information provided to estimate the effect of the change in GDP on the 4 unemployment rate (in percent).
