1. Problems and Applications Q1 Suppose the economy is in a long-run equilibrium, as shown in the following graph. Now suppose that firms become pessimistic about future business conditions and decide to cut back on investment spending, resulting in a fall in aggregate demand. Use your diagram to show what happens to output and the price level in the short run. Price Level LRAS Aggregate Supply Aggregate Demand Quantity of Output As a result of this change, the unemployment rate Aggregate Demand Aggregate Supply LRAS ? Use the sticky-wage theory of aggregate supply to think about what will happen to output and the price level in the long run (assuming there is no change in policy).

“John Maynard Keynes introduced the AD-AS macroeconomic model (aggregate demand- aggregate supply) to determine the equilibrium level of real output and the level of prices in the economy” 1. Draw a diagram with aggregate demand, short-run aggregate supply, and long-run aggregate supply. 2. Discuss the reasons why the aggregate demand curve is downward sloping, while the short-run aggregate-supply curve is upward sloping?
4.1 Distinguish between the short-run aggregate supply curve and the long-run aggregate supply curve.
1. In the following table, determine how each event likely effects potential output (a.k.a., long-run aggregate supply). Direction of Potential Output Shift Event Left Right No Shift The government allows more immigration of working-age adults. For environmental and safety reasons, the government requires that the country’s nuclear power plants be permanently shut down. An investment tax credit increases the rate at which firms acquire machinery and equipment. 2. In the following table, determine how each event affects the position of the aggregate demand curve. Direction of AD Curve Shift Event Left Right No Shift A decrease in consumer confidence (suggests people believe a contraction/recession coming) A decrease in individual income tax rates An increase in the value/price of housing 3. What effect would an increase in aggregate demand…
4.1 Why does the short-run aggregate supply curve slope upward? 4.2 Explain why the long-run aggregate supply curve is vertical. Then, (verbally and graphically) explain how each of the following events would affect the long-run aggregate supply curve. a. A lower price levels b. A decrease in the labor force c. A decrease in the quantity of capital goods d. Technological change
1) What effects might each of the following have on aggregate demand/aggregate supply? In each case use a diagram to illustrate the effect, explain why shifts occurred, and state the impact of each event on the price levels, the unemployment rate, and real GDP. a. Congress passes into law a $1.5 billion cut in personal income taxes. b. Significant technological advances in the renewable energy sector decrease the price of all electricity by 50% c. Increases in consumer confidence lead to a positive demand shock.

Need help with this. I gave possible answers(choose 1 only), also please show how to do the graph as well (where to move the new SRAS and AD if needed) Thank you!
31) Use the dynamic model of aggregate demand and supply to illustrate a situation where aggregate demand and short-run aggregate supply are both increasing from year 1 to year 2, resulting in a higher price level and higher level of real GDP at macroeconomic equilibrium in year 2. 32) Hurricane Katrina resulted in a decline in oil production infrastructure along the gulf coast. As a result there was an unexpected decline in oil and natural gas supplies in 2005. Suppose that this caused an increase in the price level and a decline in real GDP in 2006. Also assume that potential real GDP continued to grow due to other factors. You can assume the aggregate demand curve did not change. Show the macroeconomic equilibrium for 2005 and 2006 using the dynamic aggregate supply and aggregate demand model. 1
a. Beginning with long-run equilibrium, use the aggregate demand (AD) and aggregate supply (AS) model to explain (and illustrate) what happens in the short run when the economy suffers a negative supply shock. Be sure to detail what happens to aggregate demand, aggregate supply, the price level, the level of GDP, and unemployment.
es/118790/quizzes/952344/take OS D SU My ASU ASU CANVAS Question 2 Which of the following would cause a shift in the short-run aggregate supply curve, but no change in the long-run aggregate supply curve? O an increase in the size of the labor force an increase in the wage rate an increase in the quantity of capital O all of the above would shiftboththe long-run aggregate supply curve and the short-run aggregate supply curve. Question 3 Which of the following would NOT lead to a shift in the long- run aggregate supply curve? O An increase in the money supply. 1
In terms of the statement below, what are the 2 main factors affecting the aggregate supply curve. Explain these factors and use a diagram. "Fluctuations in employment over the business cycle bring fluctuations in real gross domestic product. However, these changes in real GDP are fluctuations around potential GDP. It is not changes in potential GDP and long run aggregate supply."
