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.

The increase in government spending will cause the unemployment rate to

The aggregate demand function: yad =C+1+G₁ = 500+ 0.75Y is plotted on the graph to the right. The graph also shows the 45° line where aggregate output Y equals aggregate demand yad for all points. What happens to aggregate output if government spending rises by 100? The equilibrium level of output rises by $ billion. (Round your response to the nearest billion.)

Consider the graph at right showing an economy in recession. Aggregate demand is currently at AD. Equilibrium currently occurs at Eo. If aggregate demand was ADF, there would be full employment. Suppose the government engages in fiscal policy that results in full crowding out. Using the line drawing tool, draw the new demand curve that shows full crowding out. Carefully follow the instructions above, and only draw the required object. Price level Eo EF ADO F Real GDP per Year ($ trillions) SRASO ADF O U

The following graph shows a hypothetical economy in long-run equilibrium at an expected price level of 120 and a natural output level of $300 billion. Suppose a stock market boom increases household wealth and causes consumers to spend more.

Again, the following graph shows a hypothetical economy experiencing long-run equilibrium at the expected price level of 120 and natural output level of $300 billion, prior to the…

The Greek letter a represents a number that determines how much output responds to unexpected changes in the price level. In this case, assume that a = $2 billion. That is, when the actual price level exceeds the expected price level by 1, the quantity of output supplied will exceed the natural level of output by $2 billion. Suppose the natural level of output is $50 billion of real GDP and that people expect a price level of 95. On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (LRAS) curve. Then use the orange line segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 85, 90, 95, 100, and 105.

Consider a hypothetical closed economy in which there are no income taxes. If households spend $0.75 of each additional dollar they earn and save the remainder, the expenditure multiplier for this economy is The following graph shows the initial aggregate demand (AD) and short-run aggregate supply (SRAS) curves of this economy. Suppose that the economy is currently in a recession. Business firms are pessimistic about the future and do not respond to a fall in interest rates. In addition, all households are pessimistic about job prospects and desire to consume less and save more at all levels of income. As a result, personal consumption in this economy decreases by $1 billion. The reduction in personal consumption will lead to a decrease in aggregate demand by S Shift either the AD curve or the SRAS curve, or both, to show the new aggregate demand curve after the full impact of the multiplier process of the reduction in personal consumption has taken place.

Following an increase in consumer confidence, the US economy is experiencing a significant increase in aggregate spending. Using a correctly labeled aggregate demand and aggregate supply diagram, show how the change in aggregate spending will affect each of the following in the short run -Output -The price level
