Suppose that workers and firms perfectly forecast inflation, so that the real wage remains unchanged as the price level rises over time. Prices and wages rise at the same rate, which implies that the real wage stays constant. The following graph shows the aggregate demand curve (AD) in an economy in long-run equilibrium. Assume the natural rate of unemployment is 5%, and potential output is $40 trillion. Use the orange points (square symbols) to draw the aggregate supply curve in this case, and use the black point (X symbol) to mark the equilibrium price level and real GDP.

Suppose the full employment output level in this economy is $320 billion. In order to move the economy to full-employment output at the lowest possible price level, the aggregate demand curve must shift to the by at each price level. Use the green line (triangle symbols) to show the shift in aggregate demand necessary to return the economy to full employment. Then use the purple drop lines (diamond symbol) to show the macroeconomic equilibrium at full-employment output. Be sure the new aggregate demand curve (AD₂) is parallel to AD₁. You can click on AD, to see its slope. Suppose the government in this economy wants to enact fiscal policies that will shift the aggregate demand curve in the direction and magnitude you indicated. The marginal propensity to consume (MPC) in this economy is 0.50. This implies a spending multiplier of ▼ and tax multiplier of Consider each fiscal policy listed here. Which policies would shift the aggregate demand curve in a way that restores full-employment…
In the short run, the quantity of output supplied by firms can deviate from the natural level of output if the actual price level deviates from the expected price level in the economy. A number of theories explain reasons why this might happen. For example, the sticky-price theory asserts that the output prices of some goods and services adjust slowly to changes in the price level. Suppose firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. Many of the firms sell their goods through catalogs and face high costs of reprinting if they change prices. The actual price level turns out to be 110. Faced with high menu costs, the firms that rely on catalog sales choose not to adjust their prices. Sales from catalogs will and firms that rely on catalogs will respond by the 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…
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 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 the output prices of some goods and services adjust slowly to changes in the price level. Suppose firms announce the prices for their products in advance, based on an expected price level of 100 for the coming year. Many of the firms sell their goods through catalogs and face high costs of reprinting if they change prices. The actual price level turns out to be 90. Faced with high menu costs, and firms that rely on catalogs the firms that rely on catalog sales choose not to adjust their prices.

6. Why the aggregate supply curve slopes upward in the short run In the short run, the quantity of output supplied by firms can deviate from the natural level of output if the actual price level deviates from the expected price level in the economy. A number of theories explain reasons why this might happen. For example, the misperceptions theory asserts that changes in the price level can temporarily mislead firms about what is happening to their output prices. Consider a soybean farmer who expects a price level of 100 in the coming year. If the actual price level turns out to be 90, soybean prices will and if the farmer mistakenly assumes that the price of soybeans declined relative to other prices of goods and services, the quantity of soybeans supplied. If other producers in this economy mistake changes in the price level for changes in their relative prices, the unexpected decrease in the price level causes the quantity of output supplied to level of output in the short run. she…
Suppose the aggregate demand (AD) and short-run aggregate supply (AS) schedules for an economy whose potential GDP (LRAS) equals to $2,700 are given by the table. Now suppose aggregate demand increases by $700 at each price level; for example, the new aggregate demanded at a price level of 50 now equals to $4,200. How will the shift in AD change the original output, price level, and employment? Name one factor that can cause the increase in aggregate demand and the shifting of the curve.
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 Quantity of Output As a result of this change, the unemployment rate Aggregate Demand On the graph, illustrate the change that will occur in the long run. 1 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).
Suppose the full-employment level of real output ( Q) for a hypothetical economy is $250 and the price level (P ) initially is 100. Use the short-run aggregate supply schedules below to answer the questions that follow: a. What will be the level of real output in the short run if the price level unexpectedly rises from 100 to 125 because of an increase in aggregate demand? What if the price level unexpectedly falls from 100 to 75 because of a decrease in aggregate demand? Explain each situation, using figures from the table.b. What will be the level of real output in the long run when the price level rises from 100 to 125? When it falls from 100 to 75? Explain each situation.c. Show the circumstances described in parts a and b on graph paper, and derive the long-run aggregate supply curve.
The following graph plots aggregate demand (AD2027AD2027) and aggregate supply (AS) for the imaginary country of Cotopaxi in the year 2027. Suppose the natural level of output in this economy is $6 trillion. On the following graph, use the green line (triangle symbol) to plot the long-run aggregate supply (LRAS) curve for this economy. Economists forecast that if the government takes no action and the economy continues to grow at the current rate, aggregate demand in 2028 will be given by the curve labeled ADAADA, resulting in the outcome given by point A. If, however, the government pursues an expansionary policy, aggregate demand in 2028 will be given by the curve labeled ADBADB, resulting in the outcome given by point B. The following table presents projections for the unemployment rates that would occur at point A and point B. Consider the potential rate of inflation between 2027 and 2028, depending on whether the economy moves from the initial price level of 102 to the…

The graph below depicts an increase in aggregate demand due to an increase in net exports. This increase in aggregate demand is depicted as a shift from AD to AD₁. Price Level LRAS X AD Real GDP AS AD Tools AS, 0 a. In the long run, aggregate supply will adjust to move the economy back to the full-employment level of output. Show this shift using the graph above. Instructions: Use the tool provided "AS₁" to show the movement back to full-employment output. Plot only the endpoints of the line, keeping AS, parallel to AS with the appropriate Intersection (2 points total). b. How does the new long-run equilibrium compare to the Initial full-employment level before the Increase in net exports? O The price level is higher, but output is lower. O The price level is lower, but output remains the same. O The price level is lower, but output is higher. O The price level is higher, but output remains the same.
