Instructions: Enter your answer as a whole number. If you are entering a negative number include a minus sign. a. How much does aggregate demand need to change to restore the economy to its long-run equilibrium? $ | billion b. If the MPC is 0.9, how much does government purchases need to change to shift aggregate demand by the amount you found in part a? billion Suppose instead that the MPC is 0.5. c. How much does aggregate demand and government purchases need to change to restore the economy to its long-run equilibrium?

? G The following graph shows a hypothetical economy in long-run equilibrium at an expected price level of 120 and a natural output level of $600 billion. Suppose the government increases spending on building and repairing highways, bridges, and ports. Using the graph, shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the short-run impact of the increase in government spending. PRICE LEVEL 240 200 AS 160 120 80 40 0 0 200 400 600 AD 800 1000 1200 OUTPUT (Billions of dollars) ŏ AD 一 AS (?) In the short run, the increase in government spending on infrastructure causes the price level to the quantity of output to the price level people expected and the natural level of output. The increase in government spending will cause the unemployment rate to the natural rate of unemployment in the short run. Again, the following graph shows a hypothetical economy experiencing long-run equilibrium at the expected price level of 120 and natural output level of…
