Question 1

Refer to the information provided in Table 8.5 below to answer the questions that follow.
Table 8.5
A Hypothetical Investment Schedule 
-Refer to Table 8.5. If the interest rate dropped from 15% to 6%, planned investment would ________ by $________ billion.

Accepted Answer

A drop in the interest rate from 15% to 6% would typically lead to an increase in planned investment, as lower interest rates reduce the cost of borrowing, encouraging more investment. The specific increase of $120 billion would be based on the data provided in Table 8.5, which is not visible here.

Question 2

Firms react to negative inventory investment by increasing output.

Accepted Answer

Negative inventory investment means that firms are reducing their inventory levels, which could indicate that demand is exceeding supply. To meet this demand, firms may increase output to replenish their inventory and satisfy customers.

Question 3

In macroeconomics, equilibrium is defined as that point at which

Accepted Answer

Equilibrium in macroeconomics is typically defined as the point where planned aggregate expenditure (which includes consumption, investment, government spending, and net exports) equals aggregate output (which is the same as GDP). At this point, there is no excess demand or supply in the economy, and resources are efficiently allocated. Option A is not correct because saving does not play a direct role in determining equilibrium in the short run, although it may affect long-term growth. Option C is not correct because planned aggregate expenditure comprises more than just consumption. Option D is not correct because aggregate output is the sum of consumption, investment, government spending, and net exports, not just consumption minus investment.

Question 4

Refer to the information provided in Figure 8.8 below to answer the questions that follow.  Figure 8.8
-Refer to Figure 8.8. The amount of planned investment ________ if the interest rate rises from 4% to 8%.

Accepted Answer

As shown in Figure 8.8, at an interest rate of 4%, the amount of planned investment is $275 billion. However, if the interest rate rises to 8%, the amount of planned investment drops to $125 billion, a decrease of $150 billion. Therefore, the correct answer is choice letter A.

Question 5

Refer to the information provided in Table 8.6 below to answer the questions that follow.
Table 8.6
A Hypothetical Investment Schedule 
-Refer to Table 8.6. If the interest rate dropped from 15% to 6%, planned investment would ________ by $________ billion.

Accepted Answer

At a lower interest rate, businesses are more likely to invest because borrowing costs are lower, leading to an increase in planned investment. The specific amounts are not provided in the question, but typically, a decrease in interest rates leads to an increase in investment.

Question 6

Refer to the information provided in Figure 8.8 below to answer the questions that follow.  Figure 8.8
-Refer to Figure 8.8. The amount of planned investment ________ if the interest rate falls from 8% to 4%.

Accepted Answer

According to Figure 8.8, at an interest rate of 8%, the planned investment is $125 billion. However, if the interest rate falls to 4%, the planned investment increases to $275 billion. Therefore, the planned investment rises by $150 billion if the interest rate falls from 8% to 4%.

Question 7

If planned investment is perfectly unresponsive to changes in the interest rate, the planned investment schedule

Accepted Answer

If planned investment is perfectly unresponsive to changes in the interest rate, its schedule will be completely vertical. This implies that, regardless of what the interest rate is, there will be no change in planned investment.

Question 8

If planned investment is ________ to changes in the interest rate, the planned investment schedule is vertical.

Accepted Answer

If planned investment is perfectly unresponsive to changes in the interest rate, then the planned investment schedule is vertical. This means that changes in the interest rate will not have any impact on the planned amount of investment.

Question 9

Refer to the information provided in Figure 8.8 below to answer the questions that follow.  Figure 8.8
-Refer to Figure 8.8. The amount of planned investment increases if the interest rate

Accepted Answer

According to the graph, as the interest rate drops from 8% to 4%, the level of planned investment increases. Therefore, A is the correct choice.

Question 10

Actual investment includes unplanned changes in inventory.

Accepted Answer

Actual investment includes the unplanned changes in inventory which can affect the total investment made by a company.

Question 11

Firms hold planned inventories in anticipation of sales.

Accepted Answer

Firms hold inventories to ensure they have enough stock to meet anticipated demand from customers. These inventories are known as planned inventories.

Question 12

A firm's inventory is the orders for goods that have yet to be produced.

Accepted Answer

A firm's inventory consists of goods that have already been produced and are awaiting sale or distribution. Orders for goods that have yet to be produced would be considered part of the firm's backlog or production schedule.

Question 13

If planned investment is perfectly responsive to changes in the interest rate, the planned investment schedule

Accepted Answer

If planned investment is perfectly responsive to changes in the interest rate, it means that any change in the interest rate does not affect the level of planned investment. Therefore, the planned investment schedule is horizontal, indicating that investment does not change as interest rates change.

Question 14

If planned investment increases, equilibrium will be restored only when saving has increased by exactly the amount of the initial increase in planned investment, assuming there is no government or foreign sector.

Accepted Answer

This is the basic Keynesian theory of equilibrium, where any increase in planned investment leads to an increase in income and therefore an increase in saving, which restores equilibrium. This assumes no government or foreign sector that can affect the equilibrium.

Question 15

Keynes used the phrase animal spirits to describe the feelings of entrepreneurs, and he argued that these feelings affect investment decisions.

Accepted Answer

Keynes did use the phrase "animal spirits" to describe the psychological factors that influence economic activity, including the feelings of entrepreneurs and their willingness to invest.

Question 16

Refer to the information provided in Figure 8.8 below to answer the questions that follow.  Figure 8.8
-Refer to Figure 8.8. The amount of planned investment decreases if the interest rate

Accepted Answer

According to the graph, there is an inverse relationship between the amount of planned investment and the interest rate. As the interest rate rises from 4% to 8%, the amount of planned investment decreases. Therefore, the best choice is B.

Question 17

Firms' investments include inventories.

Accepted Answer

Firms often invest in inventories in order to meet future demand and increase production efficiency.

Question 18

Firms react to an unplanned inventory investment by increasing output.

Accepted Answer

Firms typically react to an unplanned inventory investment by reducing output to align production with lower-than-expected demand, not by increasing it.

Question 19

If planned investment is ________ to changes in the interest rate, the planned investment schedule is horizontal.

Accepted Answer

The answer of If planned investment is ________ to changes...

Question 20

Reducing the interest rate, ceteris paribus, is likely to reduce the level of planned investment spending.

Accepted Answer

Reducing the interest rate makes borrowing cheaper and therefore more attractive to businesses, which may increase their planned investment spending.
