Question 1

According to most economists,when can government debt lead to higher interest rates?

Accepted Answer

When misperceptions or default risks are significant, lenders require higher interest rates to compensate for the perceived or actual risk associated with lending money to the government. This risk can come from doubts about the government's ability to repay its debt, concerns about inflation, or other economic or political factors. In this scenario, government debt can lead to higher interest rates. However, government debt does not necessarily always lead to higher interest rates, and it is not tied solely to government spending practices.

Question 3

Suppose coal is mined at a zero marginal cost and is priced competitively.If the price of coal is growing faster than the interest rate,then coal miners

Accepted Answer

If the price of coal is growing faster than the interest rate, coal miners will have an incentive to mine and sell more coal in the present and leave less coal unmined for the future. However, since coal is a nonrenewable resource, this strategy will eventually lead to depletion of the resource. Therefore, the best choice for coal miners in this situation is to increase the amount of coal left unmined, in order to ensure that they can continue producing coal in the long run.

Question 4

If the marginal product of capital is smaller than the interest rate,then

Accepted Answer

If the marginal product of capital is smaller than the interest rate, it means that investing in capital will not yield enough returns to cover the cost of borrowing. Therefore, investment in capital will fall.

Question 5

Suppose the government spends $5,000 per person this year.The market for borrowing and lending is competitive,and the market interest rate is 6%.Which of the following plans to finance the government's spending is best for consumers?

Accepted Answer

Each option effectively costs consumers the same when considering the time value of money and the 6% interest rate. Option A is a direct $5,000 payment. Option B is the future value of $5,000 one year later at 6% interest, which is $5,300. Option C represents the perpetuity formula where the payment ($300) is equal to the interest rate (6%) times the principal ($5,000), meaning the present value of paying $300 forever is also $5,000.

Question 6

An increase in the marginal productivity of capital will lead to

Accepted Answer

An increase in the marginal productivity of capital means that each unit of capital is producing more output. As a result, the demand for capital will increase, leading to a rise in the interest rate. This is because the increased demand for capital will push up its price, i.e., the interest rate, to equilibrate the supply and demand for capital. Therefore, choice B is the correct answer. Choices A, C, and D are incorrect because none of them logically follows from an increase in the marginal productivity of capital.

Question 8

A copper mining firm has discovered that there is gold mixed in with its copper ore.Since the marginal cost of mining the gold is negligible,they are willing to sell it at the current market price of $500 an ounce.If the rate of interest is 5%,the firm should expect the price next year

Accepted Answer

Question 9

When a consumer is impatient,his indifference curves for current and future consumption

Accepted Answer

When a consumer is impatient, they value current consumption more than future consumption. As a result, their indifference curves for current and future consumption will have absolute slopes greater than 1 along the 45° line. This is because the consumer is willing to give up more future consumption for a smaller increase in current consumption.

Question 10

Which of the following is not a reason to expect the slope of a consumer's indifference curve for current and future consumption to be greater than 1 with an endowment along the 45° line?

Accepted Answer

A decline in interest rates would reduce the opportunity cost of current consumption, making the consumer more willing to wait and consume in the future, thus decreasing the slope of their indifference curve. On the other hand, choices A, B, and C all suggest reasons why the slope might be greater than 1, as people might prioritize present consumption over future consumption due to impatience or uncertainty about the future, or value the memories of current consumption more highly.

Question 11

Question 13

An economic analysis of "planned obsolescence" shows that

Accepted Answer

Economic analysis suggests that firms will produce longer-lived products if the additional cost of doing so is less than the present value of the benefits received by consumers. In other words, if consumers are willing to pay for a longer-lived product, and the additional cost of producing that product is less than the value of the extra benefits to consumers, then it makes sense for the firm to produce a longer-lived product. This applies to both monopolies and competitive firms, although monopolies may have more control over their pricing and product offerings, and may therefore be more likely to engage in planned obsolescence.

Question 14

When the government wants to spend money

Accepted Answer

When the government wants to spend money, it can finance it through borrowing or raising taxes. If the government borrows, interest payments will have to be made in the future which may result in higher future taxes or reduced government spending. If taxes are raised, individuals and firms will have less money to spend and may reduce their consumption which would result in lower current consumption. Therefore, current consumption will fall if the government borrows or raises taxes.

Question 15

When the interest rate is low

Accepted Answer

When the interest rate is low, borrowing is cheaper, which increases the demand for capital as businesses and individuals are more willing to invest in capital goods. However, this also means that more resources are being allocated to investment rather than being available for current consumption.

Question 16

The representative agent chooses to consume

Accepted Answer

The representative agent has no preference for current or future goods and therefore chooses to consume his endowment point.

Question 17

Suppose pizzas are the only good and people have homothetic preferences.The supply of pizzas today is perfectly inelastic and determined solely by people's endowments.Which of the following would cause the interest rate to rise?

Accepted Answer

An expected 50% increase in future pizza production would increase future supply, leading people to expect lower future prices. This would increase the incentive to save, raising the interest rate.

Question 18

Current and Future Consumption

The following questions refer to the accompanying diagram, which shows a consumer's choice between current and future consumption.

-Refer to Current and Future Consumption.The diagram shows the case of a

Accepted Answer

The diagram shows that current consumption is less than current income, indicating that the individual is a net lender, as they are saving a portion of their income for future consumption.

Question 19

The light bulbs currently made by a manufacturer currently last 1 year.People place a value of $2.42 on one year's worth of light from a light bulb,and the market rate of interest is 10%.The manufacturer is considering a quality improvement that would make its light bulbs last 3 years.Should the manufacturer make the quality improvement?

Accepted Answer

To determine if the quality improvement is worth it, we need to calculate the present value of 3 years' worth of light from a light bulb, discounted at the market rate of interest (10%). The present value (PV) of $2.42 received at the end of each year for 3 years is calculated as follows:$$ PV = \frac{2.42}{(1+0.10)^1} + \frac{2.42}{(1+0.10)^2} + \frac{2.42}{(1+0.10)^3} $$$$ PV = \frac{2.42}{1.10} + \frac{2.42}{1.21} + \frac{2.42}{1.331} $$$$ PV = 2.20 + 2.00 + 1.82 = 6.02 $$However, since the question implies a comparison to the initial $2.42 cost for one year, we need to adjust our understanding. The correct interpretation involves comparing the cost of improving the bulb to the present value of buying new bulbs each year for three years. The calculation provided was incorrect in the context of the question's intent, which is to find the break-even cost of the improvement.The correct calculation for the break-even point, considering the error in the initial explanation, should focus on the value of extending the bulb's life to 3 years from a cost perspective, not the present value of future payments. The correct approach is to find the maximum cost of improvement that makes the 3-year bulb equivalent in present value terms to buying a new bulb each year, under the given interest rate.Given the mistake in the calculation process, the correct answer hinges on understanding that the improvement should be worthwhile if the cost is less than the combined present value of purchasing new bulbs annually for three years, taking into account the 10% interest rate. The correct present value calculation for the three years of light (without the mistake of summing future values of $2.42 directly) would indeed suggest that the improvement is worth it if the cost is less than the present value of buying bulbs annually, adjusted for the interest rate. Given this, the correct rationale is that the manufacturer should proceed with the improvement if the cost is less than what consumers would otherwise pay (in present value terms) for replacing the bulb each year over three years, considering the time value of money. The option suggesting a threshold cost below which the improvement is justified reflects the need to compare the improvement cost against the present value of future savings from not having to replace the bulbs as frequently.

Question 20

When the supply of land is perfectly inelastic,the economic burden of an annual tax on land

Accepted Answer

When the supply of land is perfectly inelastic, it means that the quantity of land available does not change regardless of the price. Therefore, a tax on land cannot be passed on to future buyers through higher prices or split between present and future landowners, as the supply of land does not adjust to the tax. The economic burden of the tax falls entirely on the people who owned land when the tax was imposed, as they cannot escape the tax by altering the supply of land.
