Question 1

For providing their resources to firms, workers, loanable funds' suppliers, landowners, and entrepreneurs, receive (in the same order)

Accepted Answer

Workers receive wages for their labor, loanable funds' suppliers (such as savers or banks) receive interest on the capital they provide, landowners earn rent from their property, and entrepreneurs gain profit from their business ventures.

Question 2

Entrepreneurs, if successful, earn

Accepted Answer

Entrepreneurs earn profit if their business is successful.

Question 3

Suppose Frank quits his $25,000 a year job and starts his own hauling company. He takes $10,000 out of his savings account at the bank, where he was earning 5 percent interest, to buy a truck. His other expenses, including the truck, are $20,000. Frank's revenues are$48,000. Frank ends up with

Accepted Answer

Frank's opportunity cost includes his forgone salary ($25,000) and the interest he would have earned on his savings ($10,000 * 5% = $500), totaling $25,500. His total costs, including the opportunity cost, the initial investment for the truck, and other expenses, are $25,500 + $10,000 + $20,000 = $55,500. With revenues of $48,000, his profit is $48,000 - $55,500 = -$7,500. However, since there's no option matching this calculation directly and considering the provided options, the closest correct interpretation based on the given options is that there might have been a misunderstanding in the calculation process. Given the options and typical approach to such a problem, the correct answer would involve calculating the net profit or loss correctly, considering all expenses and revenues. Without a direct match, we revisit the calculation: Frank's explicit costs are $20,000 (excluding the truck, which is an investment from savings), and his implicit costs are $25,500 (forgone salary + forgone interest). His total revenue is $48,000. The profit (or loss) calculation should consider both explicit and implicit costs against the revenue. However, given the options and the mistake in the initial explanation, there seems to be a misunderstanding in the calculation or interpretation of the options. The correct approach to finding entrepreneurial profit would subtract all costs (explicit and implicit) from the revenue.

Question 4

If the loanable funds market pays 8 percent and you want to earn $1,000 a year of interest income, how much in loanable funds must you supply to the market in order to accomplish this?

Accepted Answer

The answer of If the loanable funds market pays 8...

Question 5

The addition to total physical product when one more unit of capital (or loanable funds) is used in production is called

Accepted Answer

The marginal physical product of capital refers to the additional output (total physical product) generated from the use of one more unit of capital in the production process.

Question 6

The marginal revenue product of capital is the

Accepted Answer

The marginal revenue product of capital refers to the additional revenue a firm generates by investing an additional unit of capital, in this case, an additional $1 of loanable funds. It does not directly relate to the interest rate changes, the price of adding machinery, or the comparison to labor or physical products.

Question 7

When Jim adds $1,000 worth of farm equipment to his production process, he finds tha this corn output increases from 200 to 350 bushels. If the price of corn is $2 per bushel, the marginal revenue product of capital is

Accepted Answer

The marginal revenue product (MRP) of capital is calculated by the increase in total revenue from the additional capital. Here, the increase in corn output is 150 bushels (350 - 200), and at $2 per bushel, the increase in revenue is $300 (150 bushels * $2/bushel).

Question 8

Polly estimates that if she spends another $10,000 to upgrade the computer equipment at her tax preparation company, the number of tax returns she can handle will increase from 200 to 280. She charges an average of $50 to do each tax return. The MRP per dollar of this $10,000 upgrade is

Accepted Answer

The MRP per dollar of the $10,000 upgrade is calculated by determining the additional revenue generated by the upgrade and then dividing that by the cost of the upgrade. The upgrade allows Polly to handle 80 more tax returns (280 - 200), and at $50 each, this generates an additional $4,000 (80 * $50). Dividing this additional revenue by the cost of the upgrade ($4,000 / $10,000) gives 0.4, or 40 percent.

Question 9

Money that a firm uses to buy the physical plant, equipment, and raw materials for production is called

Accepted Answer

Loanable funds are the money that a firm uses to buy the physical plant, equipment, and raw materials for production. This term refers to the money available for borrowing, which businesses can use to invest in physical capital.

Question 10

-In Exhibit Q-4, the marginal physical product of capital generated by increasing loanable funds from $3,000 to $4,000 is

Accepted Answer

The answer of 
-In Exhibit Q-4, the marginal physical product...

Question 11

-In Exhibit Q-4, if the price of a bicycle helmet is $10, the MRP of increasing the loanable funds used by the firm from $2,000 to $3,000 is

Accepted Answer

The MRP of increasing the loanable funds used by the firm from $2,000 to $3,000 is $700. This is because the increase in loanable funds allows the firm to purchase an additional bicycle helmet, which has a price of $10. The MRP is therefore equal to the additional revenue generated by the sale of the additional bicycle helmet, which is $10.

Question 12

-In Exhibit Q-4, if the price of a bicycle helmet is $10 and the interest rate is 20 percent, how much in loanable funds should the firm demand?

Accepted Answer

Given the price of a bicycle helmet is $10 and the interest rate is 20 percent, the firm would demand $5,000 in loanable funds if this amount allows it to undertake projects or operations (such as producing bicycle helmets) that it expects will generate a return higher than the 20 percent interest rate. Without specific details from Exhibit Q-4, the correct answer hinges on understanding the relationship between the cost of borrowing (interest rate) and the amount a firm is willing to borrow to finance its investments, assuming those investments yield returns greater than the borrowing cost.

Question 13

-In Exhibit Q-4, if the price of a bicycle helmet is $10 and the firm increases its quantity of loanable funds demanded from $3,000 to $4,000, then the MRP per dollar is

Accepted Answer

The MRP per dollar is calculated by dividing the increase in revenue by the increase in investment. Here, the increase in revenue is $10 (the price of a bicycle helmet), and the increase in investment is $1,000 (from $3,000 to $4,000). Thus, MRP per dollar = $10 / $1,000 = 0.01 or 1%. However, given the options do not align with this calculation, it seems there might be a misunderstanding in the interpretation of the question or a mistake in the calculation process based on the provided options. The correct approach to find the MRP per dollar involves understanding the additional revenue generated per additional dollar invested, which typically would follow the formula mentioned. If we were to assume a direct relationship between the increase in loanable funds and the increase in revenue generated (which is not directly provided here), the correct answer would require more specific information from Exhibit Q-4 to accurately calculate the MRP per dollar. Given the options and the typical way to calculate MRP per dollar, none of the provided choices directly match the expected calculation, indicating a possible error in the question interpretation or a need for additional information from Exhibit Q-4.

Question 14

Every resource has its price. The price of loanable funds is expressed as

Accepted Answer

The price of loanable funds is expressed as a rate of interest, which is the cost of borrowing those funds or the return for lending them.

Question 15

A firm's demand curve for loanable funds is

Accepted Answer

The firm's demand curve for loanable funds is the same as the marginal revenue product of capital curve because firms demand funds up to the point where the marginal revenue product of capital equals the interest rate.

Question 16

When we add together all the individual firm's demands for loanable funds, we get the

Accepted Answer

The market demand for loanable funds is derived from adding together all the individual firm's demands for loanable funds. This reflects the total amount of funds that firms across the economy wish to borrow at various interest rates.

Question 17

The supply of loanable funds reflects the willingness of

Accepted Answer

The supply of loanable funds is primarily determined by the willingness of savers to defer consumption and provide those funds to the market, which they do at various interest rates. This reflects the basic economic principle that higher interest rates incentivize more saving, as the return on saved funds increases.

Question 18

The marginal factor cost of borrowing $1,000 for new equipment when the interest rate is 10 percent and the MRP is $700 is

Accepted Answer

The marginal factor cost of borrowing $1,000 at an interest rate of 10 percent is $100, which is calculated as 10% of $1,000.

Question 19

As interest rates increase, the quantity of loanable funds that are supplied to the loanable funds market

Accepted Answer

Higher interest rates make saving more attractive, leading to an increase in the quantity of loanable funds supplied as people seek to earn more interest on their savings.

Question 20

The equilibrium interest rate is determined by the

Accepted Answer

The equilibrium interest rate in financial markets is determined by the supply and demand for loanable funds. This encompasses the willingness of savers to lend money and the desire of borrowers to take out loans, with the interest rate adjusting to balance the quantity supplied and demanded.
