2. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output that firms supply can deviate from the natural rate of output if the actual price level in the economy deviates from the expected price level. Several theories explain how this might happen. For example, the sticky price theory asserts that output prices of some goods and services adjust slowly to changes in the price level. Suppose that firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. Additionally, assume that many of the firms sell their goods through catalogues and face high costs of reprinting if they change prices. Now suppose that the actual price level turns out to be 110 (that is, prices in the economy are higher than expected). Faced with high menu costs, the firms that rely on catalogue sales choose not to adjust their prices. Sales from catalogues will and firms that rely on catalogues will respond by, quantity of output they supply. If enough firms face high costs of adjusting prices, the unexpected increase in the price level causes the quantity of output supplied to the natural rate of output in the short run. the

Suppose that the coronavirus pandemic (COVID 19) in 2020 has resulted in a leftward shift of the aggregate demand curve (it has also shifted the short-run aggregate supply to the left, but let’s ignore this effect here for simplification). A. Use the aggregate-demand/aggregate-supply model to show the effects on output and the price level/inflation in both the short run and long run (assume that the short-run aggregate supply curve is upward sloping). B. Show the adjustment process of the economy from the short run to the long run. C. What is the effect on unemployment in short run and long run? D. Can policymakers use monetary policy (and/or fiscal policy) to accommodate this shock? Describe what happens to the economy in response to this policy action.
2) Use the table above to answer the following questions.a) What is the value of real GDP and price level at the long run macroeconomic equilibrium?b) What is the value of real GDP and price level at the short run macroeconomic equilibrium?c) Is the short-run macroeconomic equilibrium a full-employment equilibrium, below full-employment equilibrium, or above full-employment equilibrium?d) How will this economy return to its long run equilibrium? Explain using self-correctingmechanism.

Suppose the economy is in the long-run equilibrium. b. Now suppose war in the world's main oil- producing region sharply reduces the world oil supply, causing oil prices to rise and increasing the costs of producing goods and services in this economy. Use your diagram to show what happens to output and the price level in the short run. c. Use the sticky-wage theory of aggregate supply to explain what will happen to output and the price level in the long run (assuming there are no policy changes). What role does the expected price level play in this adjustment? Be sure to illustrate your analysis in a graph.

Determine whether each of the following would cause a shift of the aggregate demand curve, a shift of the aggregate supply curve, a shift in neither curve, or shift in both curves. If a shift is caused, indicate which curve shifts, and in which direction it shifts. What happens to aggregate output and the price level in each case? 4. The wages rate decreases.

In this case, the economy is producing at an output level potential output. At current prices and wage levels, real wages are what firms and workers expected when they agreed on wage curve to shift to the contracts.

6. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output that firms supply can deviate from the natural level of output if the actual price level in the economy deviates from the expected price level. Several theories explain how this might happen. For example, the sticky-wage theory asserts that output prices adjust more quickly to changes in the price level than wages do, in part because of long-term wage contracts. Suppose a firm signs a contract agreeing to pay its workers $15 per hour for the next year, based on an expected price level of 100. If the actual price level turns out to be 90, the firm's output prices will , and the wages the firm pays its workers will remain fixed at the contracted level. The firm will respond to the unexpected decrease in the price level by v the quantity of output it supplies. If many firms face similarly rigid wage contracts, the unexpected decrease in the price level causes the quantity of output…
