Topic 3.1 - Aggregate Demand (AD) 13. Canadians buy more Arnericanmade cars 14. Lower interest rates affect investment L L Part 3 - Making Connections- Read the quote regarding the Great Recession and answer the questions. 'i.. these events have. . . destroyed jobs. hamstrung economic growth and led to sham declines in the values of many homes and businesses. The best and most comprehensive solution is to nd ways to a stronger economy...onty a strong economy Wm allow people who need jobs to find them.\" Ben Bemanke. Chairman of the Federal Reserve {2012) 15. What most likely happened to aggregate demand in the US to cause the Great Recession? Use specic words or phrases from the quote above to support your answer. 16. The Federal Reserve has the powerto manipulate interest rates. Do you think that Ben Bemanke recommended higher interest rates or lower interest rates to create a \"stronger economy\"? Explain your reasoning. Part 4 - Stretch Your 1hinking Answer the folioMng questrbn. 1?. The wealth effect, interestrate effect, and exchangerate effect all help explain why the aggregate demand curve is downward sloping. Phyllis, a fellow student in your AP Macro class, suggests that the substitution effect that you learned about in Unit '1 also explains why aggregate demand curve is downward sloping. She reasons that since it explains why a market demar'd curve is downward sloping, it must also be valid for aggregate demand. Explain why Phyllis is wrong. Part 3 - Making Connections- Use the information from the March 2019 Forbes article to answer the questions. "African economies are primed to be ranked among the fastest growing in the world in 2019. According to the International Monetary Fund (IMF), projections for the region's economic growth next year has been bumped up to 3.5% - 4% from earlier projections of 3% growth. If you set aside Angola, Nigeria, and South Africa, the region's projected growth rate jumps to 5.7%. Among those nations primed for growth is Zambia, which thanks to the steady rebound of commodity prices, an improvement in the global economy and improved capital market access, enjoyed 5% growth in the third quarter of 2018, up a half-point from a year earlier... The highest inflation rate of 2018 was recorded at 8.3% in October..." 8. According to this article excerpt, is the Zambian economy most likely experiencing a positive output gap or a negative output gap? Use evidence from the excerpt to support your conclusion. 9. What will happen to nominal wages in Zambia in the short run? Explain. 10. What will happen to nominal wages in Zambia in the long-run? Explain. 11. What will happen to real wages if nominal wages increase 12% and inflation continues to be at 8%? Explain. 12. Draw a correctly labeled AS/AD model with AD, SRAS, and LRAS curves representing the Zambia economy with the output gap you identified in question #8. Label the price level, PL,, and output level, Y, and full employment output, YF. 13. Assume that wages and resource prices adjust in the long-run. Draw the change that occurs on the graph and label the price level, PL, and output level, Yz. 14. Assume instead that Zambia experiences a significant increase in investment and capital stock. How would this affect the LRAS? Explain.Topic 3.2 - Multipliers Part 3: More Practice- Assume that in the year 2025 the US economy is in a recession that would require a $1 Trillion increase in total spending to get back to full employment output. Answer the following questions assuming that the marginal propensity to consume is 0.8. 11. Identify the least amount the government could spend to get the economy back to full employment. Show your work. 12. Identify the dollar amount of a tax cut to bring the economy back to full employment. Show your work. Part 4: Article Analysis- In November 2018, GM announced that it would be shutting down four additional manufacturing plants. Read the article excerpt below and answer the following questions. "The workweek after Thanksgiving opened with a shudder as General Motors announced that it would stop production at four U.S. plants and one in Canada, dooming more than 14,000 jobs... The domino effects extend outside the auto industry and, if towns aren't swift or lucky at rescuing themselves, can spiral a local economy down. "Businesses across the community suffer - not just suppliers or service providers who directly supported a closed plant, but also restaurants and bars and retailers of all kinds," John Russo and Sherry Linkon, leaders in working-class studies who used to teach at Youngstown State University, wrote in CityLab... Janesville, which has been spared the worst, lost day-care centers because out-of-work parents no longer needed someone else to keep their kids. Bowling alleys suffered because people without incomes dropped out of leagues." 13. Give your own example of a business (or industry) that would likely be affected by the closure of the GM plants. Explain your reasoning. 14. Imagine that you work in a town with a car manufacturing plant that closed. How do you think this will likely affect your individual MPC and MPS? Explain your reasoning. 15. At the same time that car plants closed, other parts of the country experienced different economic conditions. Utah, for example, saw a tech boom that drove up wages and reduced unemployment. Explain how this exemplifies the difficulty in attempting to calculate an MPC for the entire nation. Part 5: Stretch Your Thinking- Answer the question. 16. Suppose that Bob earns $20,000 a year and that Jimena earns $200,000 a year and that both earned a 10% increase in their disposable income.

Explain your reasoning.Macro Unit 3 Problem Set Topic 3.2 - Multipliers Part 1: Multiplier Practice- Fill in the chart with the marginal propensity to consume (MPC), marginal propensity to save (MPS), simple spending multiplier, and the maximum change in spending that occurs as a result of each of the following changes in consumption.

Answer the following questions assuming that the marginal propensity to consume was 0.75. 5. What was the maximum change in GDP from the government spending? Show your work. 6. What was the maximum change in GDP from the tax cut? Show your work. 7. What was the maximum change in GDP from the government transfers? Show your work. 8. If these numbers were accurate, what was the maximum change in GDP from the entire stimulus package? Show your work. 9. Assume instead that American consumers, fearing an economic collapse, increased their marginal propensity to save to 0.5. Would this increase, decrease, or not change the effectiveness of the stimulus package? Explain. 10. Assume the marginal propensity to save was 0.5 instead of 0.75. Calculate the maximum change in GDP from the entire stimulus package? Show your work.Macro Unit 3 Problem Set Topic 3.3 - Short-Run Aggregate Supply (SRAS) Part 1 - Check Your Understanding- Answer the questions assuming an upward sloping SRAS. 1.

With hyperinflation biting, he's making just 20 today." The Wall Street Journal, March 2019 19. According to the SRAS curve model, a higher price level should cause output to increase.
