The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion. Suppose the government increases spending on building and repairing highways, bridges, and ports. 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. 240 AS 200 AD 160 AS 120 80 AD 40 200 400 600 800 1000 1200 OUTPUT (Billions of dollars) In the short run, the increase in government spending on infrastructure causes the price level to the price level people expected and the quantity of output to 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 the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion, before the increase in government spending on infrastructure. PRICE LEVEL During the transition from the short run to the long run, price-level expectations will and the curve will shift to the Now show the long-run impact of the increase in government spending by shifting both the aggregate demand (AD) curve and the short-run aggregate supply (AS) curve to the appropriate positions. 240 AS 200 AD 160 AS 120 80 AD 40 200 400 600 800 1000 1200 OUTPUT (Billions of dollars) In the long run, as a result of the increase in government spending, the price level the quantity of output the natural rate of unemployment. the natural level of output, and the unemployment rate PRICE LEVEL

Worksheet 5: Aggregate Supply and Aggregate Demand Complete the questions below. Be sure to show your work. Upload this worksheet to Moodle. Consider the following Aggregate Supply and Aggregate Demand curves. 2. 3. D P 10 8 6 4 2 20 AS/AD 40 LRAS 60 80 140 SRAS AD Name: 100 120 GDP 4. Suppose the government increased spending (G). What would happen to Aggregate Demand? Draw the resulting curve, and mark a new equilibrium on the graph.

8. Economic fluctuations I The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion. Suppose the government increases spending on building and repairing highways, bridges, and ports. 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. 240 AS 200 AD 160 AS 120 80 AD 40 200 400 600 800 1000 1200 OUTPUT (Billions of dollars) In the short run, the increase in government spending on infrastructure causes the price level to the price level people expected and the quantity of output to 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 the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion, before the increase in…

7. The long-run aggregate supply curve and short-run adjustments Suppose an economy's short-run aggregate supply curve (SRAS), current equilibrium aggregate price level (P₁), and real GDP (Q1) are shown on the graph that follows. The economy currently has Natural Real GDP (QN) of $6 trillion. Use this information to place the orange long-run aggregate supply curve (LRAS, square symbols) in the correct position on the graph. 20 PRICE LEVEL 0 2 4 6 Q₁ REAL GDP (Trillions of dollars) 8 SRAS 10 LRAS

8. Economic fluctuations I The following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of $600 billion. Suppose a sudden and severe contraction in the housing market reduces the value of homes and causes consumers to spend less. Shift the short-run aggregate supply (AS) curve or the aggregate demand (AD) curve to show the short-run impact of the housing market slump. (2) 240 AS 200 AD 140 AS 120 80 AD 40 200 400 800 1000 1200 OUTPUT (BIlons of dollars) In the short run, the decrease in consumption spending associated with the housing market contraction causes the price level to * the price level people expected and the quantity of output to v the natural level of output. The housing market slump will cause the unemployment rate to the natural rate of unemployment in the short run. Again, the following graph shows the economy in long-run equilibrium at the expected price level of 120 and the natural level of output of…
