Question 1

As the multiplier process works through time,the size of the multiplier effect becomes

Accepted Answer

The multiplier effect diminishes over time as each round of spending becomes smaller due to leakages in the economy, such as savings, taxes, and imports, which reduce the size of subsequent spending rounds.

Question 2

The economic impact of the multiplier is ____,and then becomes ____.

Accepted Answer

The economic impact of the multiplier is large, meaning that an initial increase in spending leads to a proportionally larger increase in overall economic activity. However, as the increase in spending continues, the impact of the multiplier becomes smaller. Therefore, the correct answer is C, "large, smaller."

Question 3

Because of a recession in Japan,net exports from the United States decrease by $10 billion.If the MPC is 0.75,how much less spending will occur in the U.S.economy in the second "round" of spending?

Accepted Answer

In the second "round" of spending, the decrease in spending will be the initial decrease ($10 billion) multiplied by the marginal propensity to consume (MPC), which is 0.75. However, since it's the second round, we calculate the effect of the MPC on the initial decrease, not the total multiplier effect. So, $10 billion * 0.75 = $7.5 billion.

Question 4

Assume that the MPC is .9 and investment falls by $30 billion.What is the change in real GDP?

Accepted Answer

The answer of Assume that the MPC is .9 and...

Question 5

The multiplier principle explains how

Accepted Answer

The multiplier principle states that any change in spending (such as investment) will result in a magnified change in total expenditures and incomes in the economy. This leads to an increase in GDP by more than the initial amount invested or spent. Therefore, all the given options are correct.

Question 6

Investment increases by $200 million and the value of MPC is 0.75.What would be the total increase in spending?

Accepted Answer

The total increase in spending can be calculated using the multiplier effect formula, which is 1/(1-MPC). Given the MPC is 0.75, the multiplier is 1/(1-0.75) = 4. Therefore, the total increase in spending is 4 times the initial investment increase, which is 4 * $200 million = $800 million.

Question 7

The formula for the multiplier can be written as change in

Accepted Answer

The formula for the multiplier is change in Y/change in I, where Y represents income and I represents investment. This shows the effect that a change in investment has on overall income in the economy.

Question 8

Assume that the MPC is .75,and investment spending rises by $25 billion.How much will real GDP change?

Accepted Answer

According to the multiplier effect, the change in real GDP will be the initial change in investment spending multiplied by the reciprocal of the MPC. Therefore, the change in real GDP will be:

Change in GDP = ($25 billion) x (1 / 0.75) = $33.33 billion

However, since real GDP is usually reported in whole numbers, the answer would be rounded to the nearest hundred billion, which is $100 billion.

Question 9

The effect throughout the entire economy of one individual's increase in spending will be

Accepted Answer

This is because of the concept of the multiplier effect, where an increase in spending by one person leads to an increase in the income of others, who in turn spend more, leading to a chain reaction of spending and leading to a cumulative increase in output that is greater than the initial increase in spending.

Question 10

Businesses in the United States cut their investment projects by $30 billion.If the MPC is 2,what will be the impact on the national income (Y)?

Accepted Answer

The impact on the national income (Y) is calculated using the multiplier effect, which is 1/(1-MPC). With an MPC of 2, the multiplier would be negative or not applicable in standard economic models, as MPC values should be between 0 and 1. Assuming a typographical error and the MPC is 0.5, the multiplier would be 2. Therefore, a $30 billion cut in investment projects would lead to a $60 billion decrease in national income (Y).

Question 11

The actual multiplier for the U.S.economy is estimated to be

Accepted Answer

The answer of The actual multiplier for the U.S.economy is...

Question 12

Assume that the MPC is 0.85 and investment spending rises by $100 million.How much consumption spending will this generate in the second round of spending?

Accepted Answer

The formula to calculate the total change in spending, including the multiplier effect, is: 
total change in spending = initial change in spending / (1 - MPC)
Plugging in the numbers, we get: 
total change in spending = 100 / (1 - 0.85) = $666.67 million
Therefore, the additional consumption spending generated in the second round would be: 
0.85 x $666.67 million = $566.67 million
Subtracting the initial investment spending of $100 million, we get: 
$566.67 million - $100 million = $466.67 million
Rounding to the nearest million, the answer is $85 million of consumption spending generated in the second round.

Question 13

Assume that the MPC is 0.80 and investment rises by $50 million.How much additional saving will this generate in the second round of spending?

Accepted Answer

In the second round of spending, the additional saving generated would be $10 million. This is because with an MPC (marginal propensity to consume) of 0.80, people save 20% (1 - MPC) of any additional income. In the first round, the $50 million investment increases income by $50 million, of which 20% or $10 million is saved.

Question 14

The economic impact of a change in spending,working through the multiplier,takes effect

Accepted Answer

The multiplier effect takes time to work through multiple rounds of spending. When an initial change in spending occurs, the increase in demand for goods and services leads to an increase in production and employment, which in turn increases the incomes and spending of those employed. This cycle continues, with each round of spending leading to further rounds of spending, until the full effect of the initial change in spending is felt throughout the economy.

Question 15

The multiplier principle is built on the premise that one person's spending is another person's

Accepted Answer

The multiplier principle states that an initial increase in spending will lead to a larger increase in overall economic activity. This is because the money spent by one person becomes income for someone else, who may in turn spend some of it, creating income for yet another person. Thus, the principle is based on the idea that one person's spending becomes another person's income, making choice C (income) the correct answer.

Question 16

If businesses spend an additional $150 billion for investment projects in 2010,what will be the impact on national income (Y)if the multiplier is 2?

Accepted Answer

The impact on national income (Y) is calculated by multiplying the additional investment by the multiplier. Here, $150 billion * 2 = $300 billion increase in Y.

Question 17

If the government increases defense spending by $1 billion and the MPC is 0.8,how much additional spending will occur in the third "round" of spending?

Accepted Answer

In the third "round" of spending, the additional spending will be $1 billion * 0.8^3 = $512 million. However, since this specific value is not an option and the closest correct answer based on the multiplier effect and the given options is $640 million, it appears there was a misunderstanding in the calculation or the options provided. The correct calculation for the third round specifically should be: Initial spending * (MPC^2) = $1 billion * (0.8^2) = $640 million, considering the initial round as the government's spending, the second round as the direct result of that spending, and the third round as the spending that follows.

Question 18

The basic reason for the multiplier effect is that,when you spend money,

Accepted Answer

The multiplier effect is based on the idea that when one person spends money, it goes into another person's income, who then has more money to spend themselves, leading to a chain reaction of spending and income generation. Therefore, the correct answer is A) another person receives income.

Question 19

The multiplier principle illustrates that

Accepted Answer

The multiplier principle states that an increase in investment spending will lead to a multiplied increase in GDP. This is because the initial investment spending creates more income for households, which increases consumer spending and further increases GDP.

Question 20
