Question 1

The real wealth effect, interest rate effect, and foreign trade effect all explain why there is a(n)

Accepted Answer

The real wealth effect, interest rate effect, and foreign trade effect all explain why there is an inverse relationship between the price level and the aggregate quantity of goods demanded. As the price level increases, the purchasing power of wealth decreases (real wealth effect), interest rates tend to rise (interest rate effect), and domestic goods become more expensive relative to foreign goods (foreign trade effect), all of which lead to a decrease in the quantity of goods demanded.

Question 2

According to the ______ effect, as the price level declines, the purchasing power of financial assets increases and households purchase a greater quantity of goods and services.

Accepted Answer

The correct answer is the real wealth effect. This economic principle suggests that when the price level decreases, the real value or purchasing power of money and financial assets increases, leading households to increase their consumption of goods and services because they feel wealthier.

Question 3

According to the ______ effect, a lower price level decreases interest rates, which results in additional spending on investment goods and so increases the aggregate quantity of goods and services demanded.

Accepted Answer

The correct term is the "interest rate effect." It explains how a lower price level leads to lower interest rates, which in turn encourages more investment spending, thereby increasing the aggregate demand for goods and services.

Question 4

An upward movement along the aggregate demand curve is caused by a(n)

Accepted Answer

An upward movement along the aggregate demand curve is caused by an increase in the economy's price level. This movement represents how the quantity of goods and services demanded decreases as the price level rises, holding all other factors constant.

Question 5

With stock prices rising, Americans who hold stocks suddenly become less concerned about saving for retirement and increase their current consumption. As a result, the

Accepted Answer

When Americans who hold stocks feel wealthier due to rising stock prices, they are likely to increase their current consumption. This increase in consumption directly contributes to an increase in aggregate demand, hence the aggregate demand curve shifts rightward.

Question 6

Due to expectations of a future recession, companies do not think that they can sell all of their output and therefore purchase less equipment and machinery. As an immediate result, the

Accepted Answer

When companies expect a future recession and thus decide to purchase less equipment and machinery, it indicates a decrease in investment spending. This decrease in investment spending is a component of aggregate demand. Therefore, the aggregate demand curve shifts leftward, reflecting a decrease in overall demand in the economy.

Question 7

Because of dwindling political tensions with China, the U.S. government reduces its expenditures on missiles and jet aircraft. Therefore, the

Accepted Answer

Reducing expenditures on missiles and jet aircraft decreases government spending, a component of aggregate demand, leading to a leftward shift in the aggregate demand curve.

Question 8

According to the multiplier effect, changes in aggregate demand result in ______ changes in national output.

Accepted Answer

The multiplier effect suggests that changes in aggregate demand lead to proportionally larger changes in national output, as initial increases in spending lead to further increases in income and consumption.

Question 9

The size of the multiplier depends on the

Accepted Answer

The size of the multiplier in economics primarily depends on the spending and saving patterns of businesses and individuals, as these patterns determine how much of an initial injection of spending will be further spent or saved, influencing the overall impact on the economy.

Question 10

Suppose that the economy's marginal propensity to consume is 0.67. Assuming that prices are constant, a $200 million increase in investment spending would increase equilibrium real GDP by

Accepted Answer

The increase in equilibrium real GDP can be calculated using the multiplier effect formula: Multiplier = 1 / (1 - MPC), where MPC is the marginal propensity to consume. Here, MPC = 0.67, so the multiplier = 1 / (1 - 0.67) = 3.03. Therefore, a $200 million increase in investment spending would increase GDP by 3.03 * $200 million = $606 million, which is closest to $600 million (D).

Question 11

Suppose that the economy's marginal propensity to consume is 0.75. Assuming that prices are constant, a $175 million decrease in government purchases of goods and services would decrease equilibrium real GDP by

Accepted Answer

The answer of Suppose that the economy's marginal propensity to...

Question 12

Suppose that the economy's marginal propensity to save is 0.2. Assuming that prices are constant, a $30 million decrease in net exports would decrease equilibrium real GDP by

Accepted Answer

The answer of Suppose that the economy's marginal propensity to...

Question 13

The formula for the multiplier is

Accepted Answer

The formula for the multiplier, which is used in economics to analyze the impact of fiscal policy on income, is 1 / (1 - MPC), where MPC stands for the marginal propensity to consume. This formula reflects how an initial change in spending leads to a larger change in national income.

Question 14

For the full multiplier effect to occur, there must be

Accepted Answer

For the full multiplier effect to occur, there must be some idle resources in the economy. This allows increased spending to lead to more production rather than just higher prices, facilitating the multiplier effect without causing inflation.

Question 15

Rising prices in the economy tend to

Accepted Answer

Rising prices in the economy can lead to a decrease in the size of the multiplier because as prices increase, the real value of money decreases, leading to a reduction in consumer spending and investment. This, in turn, reduces the overall impact of an initial increase in spending on the total economic output, thus decreasing the multiplier effect.

Question 16

When the economy is in a depression, the economy is operating on that portion of the aggregate supply curve that is

Accepted Answer

When the economy is in a depression, it is operating on the horizontal portion of the aggregate supply curve. This indicates that there are idle resources and the economy can increase output without increasing the price level, reflecting a situation of significant underutilization of resources.

Question 17

Which of the following will cause the aggregate supply curve to shift to the right?

Accepted Answer

Increases in productivity, such as through new work rules that enhance labor efficiency, can lower production costs, thereby shifting the aggregate supply curve to the right. This reflects an increase in the total supply of goods and services at every price level.

Question 18

Suppose that entrepreneurs develop new technologies that increase the economy's productivity. As a result, the aggregate supply curve would

Accepted Answer

When new technologies increase the economy's productivity, it means that the economy can produce more goods and services for the same amount of inputs. This increase in productivity shifts the aggregate supply curve to the right, indicating an increase in the total supply of goods and services at every price level.

Question 19

Given an upward-sloping aggregate supply curve, an increase in aggregate demand results in a(n)

Accepted Answer

An increase in aggregate demand, when the aggregate supply curve is upward sloping, leads to both an increase in the price level and an increase in output. This is because higher demand for goods and services pushes prices up, while producers respond by increasing output to meet the higher demand.

Question 20

A decrease in the aggregate supply curve generally results in a(n)

Accepted Answer

A decrease in the aggregate supply curve typically leads to higher prices and lower output, as the reduced supply of goods and services in the economy pushes prices up while making less available for consumption or investment.
