Why the Aggregate Demand Curve Is Downward Sloping

The aggregate demand curve slopes downward because a higher price level: Reduces the real value of household wealth, which decreases consumption Raises interest rates, which decreases investment and consumption Makes U.S. exports more expensive and foreign imports less expensive, which decreases net exports

aggregate demand curve is downward sloping because

a fall in the price level increases the quantity of real GDP demanded

^ consumption will shift the aggregate demand curve to the_____ households become more pessimistic about their future incomes, the aggregate demand curve will shift to the_______

right left

If any variable other than the price level changes then...

the aggregate demand curve will shift

What are the Variables That Shift the Aggregate Demand Curve?

1. Changes in government policies 2. Changes in the expectations of households and firms 3. Changes in foreign variables

Which of the following factors does not cause the aggregate demand curve to​ shift? A. a change in the price level B. a change in government monetary or fiscal policies C. a change in foreign variables D. a change in the expectations of households and firms

A. a change in the price level

The interest rate effect refers to the fact that a higher price level results in A. higher interest rates and lower investment. B. higher interest rates and higher investment. C. lower interest rates and lower investment. D. lower interest rates and higher investment.

A. higher interest rates and lower investment.

The federal government decreases taxes. This causes a A. shift of the aggregate demand curve. Your answer is correct. B. movement along the aggregate demand curve.

From August 2009 to May​ 2017, the Standard​ & Poor's Index of 500 stock prices increased by more than 135​ percent, while the consumer price index increased by less than 15 percent. These changes would have caused A. an increase in the real value of household​ wealth, which shifted the aggregate demand curve to the left. B. an increase in the real value of household​ wealth, which shifted the aggregate demand curve to the right. C. a decrease in the real value of household​ wealth, which shifted the aggregate demand curve to the right. D. a decrease in the real value of household​ wealth, which shifted the aggregate demand curve to the left.

A curve that shows the relationship in the short run between the price level and the quantity of real GDP supplied by firms.

Short-run aggregate supply (SRAS) curve

A curve that shows the relationship between the price level and the quantity of real GDP demanded by households, firms, and the government.

government.Aggregate demand (AD) curve

Changes in Foreign Variables

increase in net exports at every price level will shift the aggregate demand curve to the right. A change in net exports that results from a change in the price level in the United States will result in a movement along the aggregate demand curve, not a shift of the aggregate demand curve.

aggregate demand curve tells us the relationship between

the price level and the quantity of real GDP demanded,

Interest-Rate Effect

A higher price level will increase the interest rate and reduce investment spending, thereby reducing the quantity of goods and services demanded. A lower price level will decrease the interest rate and increase investment spending, thereby increasing the quantity of goods and services demanded.

Milovia is a small open economy. The general price level in the economy has been increasing at a rate of about 7.5 percent each year. Jane​ Wilson, an industry​ analyst, is of the opinion that such high inflation is adversely affecting aggregate demand in the economy and therefore its ability to grow. Her​ colleague, Harry​ Gomes, however, disagrees. According to​ Harry, some amount of inflation is unavoidable in a growing economy. Higher prices for products help to increase the level of corporate profits and induce firms to increase aggregate output. Which of the​ following, if​ true, will indicate that higher prices will not induce firms to increase​ output? A. The increase in the price of inputs outweighed the increase in the price of the final product. B. In spite of rising​ inflation, people in Milovia expect real incomes to increase substantially in the next few years. C. The​ country's trade balance has been positive for the last five years. D. The government purchased bonds in an open market operation last year. E. The Milovian government offers subsidies on inputs used in many manufacturing industries.

A. The increase in the price of inputs outweighed the increase in the price of the final product.

The combination of a strong U.S. dollar and weak growth overseas might result in lower U.S. exports because A.

U.S. exports become less expensive for foreign buyers while​ income, and purchasing​ power, in other countries is rising only slowly. C. U.S. exports become less expensive for foreign buyers while​ income, and purchasing​ power, in other countries is falling.

A. U.S. exports become more expensive for foreign buyers while​ income, and purchasing​ power, in other countries is rising only slowly.

The result of a strong dollar will be A. a leftward shift of the U.S. aggregate demand curve because it reduces​ exports, a spending component of aggregate demand. B. a rightward shift of the U.S. aggregate demand curve because it reduces​ exports, a spending component of aggregate demand. C. an upward movement along the U.S. aggregate demand curve because the price level will rise as fewer exports are sold. D. a downward movement along the U.S. aggregate demand curve because the price level will fall as fewer exports are sold.

A. a leftward shift of the U.S. aggregate demand curve because it reduces​ exports, a spending component of aggregate demand.

​"Weak growth​ overseas" means that A. foreign economies are growing more slowly than the U.S. economy. B. foreign inflation is growing more slowly than U.S. inflation. C. the foreign money supply is growing more slowly than the U.S. money supply. D. foreign investment is growing more slowly than U.S. investment.

A. there will be a movement up along a stationary aggregate demand curve.

An economics student makes the following​ statement: ​"It's easy to understand why the aggregate demand curve is downward​ sloping: When the price level​ increases, consumers substitute into less expensive​ products, thereby decreasing total spending in the​ economy." This statement is false because the aggregate demand curve is A. downward sloping for the same reasons as a demand curve for a single product. B. downward sloping because as prices​ rise, consumer real wealth​ declines, interest rates​ rise, and exports become more expensive.

D. upward sloping because as prices​ rise, consumer wealth​ increases, interest rates​ fall, and exports become more expensive.

B. downward sloping because as prices​ rise, consumer real wealth​ declines, interest rates​ rise, and exports become more expensive.

D. the price level and the quantity of real GDP demanded by the private​ sector: households and firms.

Changes in federal taxes and purchases that are intended to achieve macroeconomic policy objectives.

Fiscal policy ^ in government purchases shifts the aggregate demand curve to the right, and a decrease in government purchases shifts the aggregate demand curve to the left. An increase in personal income taxes reduces the amount of spendable income available to households, which reduces consumption spending and shifts the aggregate demand curve to the left. A decrease in personal income taxes shifts the aggregate demand curve to the right. An increase in business taxes reduces the profitability of investment spending and shifts the aggregate demand curve to the left. A decrease in business taxes shifts the aggregate demand curve to the right.

Increases in the growth rate of domestic GDP compared to the growth rate of foreign GDP will make the aggregate demand curve shift to the_______
