How does the aggregate demand curve change if aggregate demand increases in an economy?    a) shifts left  B) shifts to the right  NS) slides down  D) constant  TO) slides up

Describe the mechanism by which demand creates its own supply.

2. How does each of the following affect the aggregate demand curve? a. Government spending increases. b. The amount of taxes collected decreases.

9. Draw an aggregate demand and supply diagram for Japan. In the diagram, show how each of the following affects aggregate demand and supply. a. The U.S. gross domestic product falls. b. The level of prices in Korea falls. c. Labor receives a large wage increase. d. Economists predict higher prices next year.

1. How is the aggregate demand curve different from the demand curve for a single good, like hamburgers? 2. Why does the aggregate demand curve slope downward? 3. How does an increase in foreign income affect domestic aggregate expenditures and demand? 4. How does a decrease in foreign price levels affect domestic aggregate expenditures and demand? 5. How is the aggregate supply curve different from the supply curve for a single good, like pizza?

8. Explain whether each of the following events will increase, decrease, or have no effect on long-run aggregate supply. A.) The United States experiences a wave of immigration.B.) Congress raises the minimum wage to $10 per hour.C.) Intel invents a new and more powerful computer chip.D.) A severe hurricane damages factories along the East Coast.

7. Determinants of short-run aggregate supply The following graph shows a decrease in short-run aggregate supply (AS) in a hypothetical economy where the currency is the dollar. Specifically, the short-run aggregate supply curve shifts to the left from AS1AS1 to AS2AS2, causing the quantity of output supplied at a price level of 100 to fall from $200 billion to $150 billion.

2. Suppose an economy is described by the following aggregate demand and short-run aggregate supply curves. The potential level of output is $10 trillion. Aggregate Quantity of Goods and Services Price Level Demanded Supplied 3.0 $11.0 trillion $9.0 trillion 3.4 $10.8 trillion $9.2 trillion 3.8 $10.6 trillion $9.4 trillion 4.2 $10.4 trillion $9.6 trillion 4.6 $10.2 trillion $9.8 trillion 5.0 $10.0 trillion $10.0 trillion 5.4 $9.8 trillion $10.2 trillion 5.8 $9.6 trillion $10.4 trillion 6.2 $9.4 trillion $10.6 trillion 6.6 $9.2 trillion $10.8 trillion 7.0 $9.0 trillion $11.0 trillion Draw the aggregate demand and short-run aggregate supply curves. What is the initial real GDP? What is the initial price level? What kind of gap, if any, exists? After the increase in health-care costs, each level of real GDP requires an increase in the price level of o.8. For example, producing $9.0 trillion worth of goods and services now requires a price level of 3.8. What is the short- run equilibrium…

7. Provide the three major factors that can cause a shift in aggregate supply, that is, explain the three major determinants of aggregate supply. a) b) c) Now describe the change in aggregate supply (AS) that should result from each of the following changes in determinants. Assume that nothing else is changing besides the identified change. (Use “Decrease (D) " or "Increase (I).") (a) A rise in the average price of inputs; (b) An increase in worker productivity; (c) Government antipollution regulations become stricter; (d) A new subsidy program is enacted for new business investment in productive equipment; (e) Energy prices decline;

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…
