Question 1

(Scenario: Diversification)Use Scenario: Diversification.If Morris invests all of his money in the rain poncho company,what is his expected gain or loss? Scenario: Diversification
Morris is considering investing $10,000 in a sunglass company or a rain poncho company.If it is a rainy year and he invests only in the sunglass company,he will lose $5,000.However,if it is a rainy year and he invests only in the rain poncho company,he will earn $10,000.If it is a sunny year and he invests only in the sunglass company,he will earn $10,000;if he invests only in the rain poncho company,he will lose $5,000 in a sunny year.There is a 50% chance of a sunny year and a 50% chance of a rainy year.

Accepted Answer

If Morris invests all of his money in the rain poncho company, his expected gain would be:
0.5 * $10,000 (sunny year gain) - 0.5 * $5,000 (rainy year loss) = $2,500
Therefore, the best choice would be to invest all his money in the rain poncho company to gain $2,500. This is because investing in the sunglass company would result in a potential loss of $5,000 if it is a rainy year. By diversifying his investment, he could mitigate the risks associated with investing in a single company.

Question 2

(Scenario: Diversification)Use Scenario: Diversification.If Morris invests half of his money in the sunglass company and half in the rain poncho company,he will earn _____ in a sunny year and _____ in a rainy year. Scenario: Diversification
Morris is considering investing $10,000 in a sunglass company or a rain poncho company.If it is a rainy year and he invests only in the sunglass company,he will lose $5,000.However,if it is a rainy year and he invests only in the rain poncho company,he will earn $10,000.If it is a sunny year and he invests only in the sunglass company,he will earn $10,000;if he invests only in the rain poncho company,he will lose $5,000 in a sunny year.There is a 50% chance of a sunny year and a 50% chance of a rainy year.

Accepted Answer

In a sunny year, investing half in the sunglass company would yield $5,000 (half of $10,000), and investing half in the rain poncho company would result in a loss of $2,500 (half of $5,000), totaling a $2,500 gain. In a rainy year, the situation reverses but the math is the same, leading to a $2,500 gain.

Question 3

(Scenario: Diversification)Use Scenario: Diversification.If Morris invests all of his money in the sunglass company,what is his expected gain or loss? Scenario: Diversification
Morris is considering investing $10,000 in a sunglass company or a rain poncho company.If it is a rainy year and he invests only in the sunglass company,he will lose $5,000.However,if it is a rainy year and he invests only in the rain poncho company,he will earn $10,000.If it is a sunny year and he invests only in the sunglass company,he will earn $10,000;if he invests only in the rain poncho company,he will lose $5,000 in a sunny year.There is a 50% chance of a sunny year and a 50% chance of a rainy year.

Accepted Answer

If Morris invests all of his money in the sunglass company, his expected gain or loss can be calculated as the weighted average of the possible outcomes:

Expected gain or loss = (0.5 * -$5,000) + (0.5 * $10,000) = $2,500

Therefore, Morris can expect to gain $2,500 if he invests all of his money in the sunglass company. However, this is not the best choice as there is a significant risk of losing money if it is a rainy year. In order to reduce this risk, Morris should diversify his portfolio by investing some money in both the sunglass and rain poncho companies.

Question 4

The problem of adverse selection:

Accepted Answer

Adverse selection occurs when sellers have more information than buyers about the quality of a product or service. This can lead to a situation where sellers who have inferior products or services may be more likely to sell them, while sellers with superior offerings may be less inclined to participate in the market or charge higher prices. This can result in a breakdown in the market and an overall reduction in the gains from trade. The other options given are not accurate descriptions of adverse selection.

Question 5

In which situation is adverse selection MOST likely to be a problem?

Accepted Answer

Adverse selection is most likely to be a problem when buying a house directly from the previous owner because the seller has more information about the property's condition than the buyer, potentially leading to the buyer making a poor decision based on incomplete information.

Question 6

When some people know things that other people don't know,there is _____;it can _____ economic decisions.

Accepted Answer

Private information creates an information asymmetry, which can distort economic decisions.

Question 7

Investors in agricultural corporations face many correlated financial risks.Which example does NOT illustrate correlated risks for the agricultural industry?

Accepted Answer

The spread of genetically modified crops and the presence of locusts do not have a direct correlation in terms of financial risks for agricultural corporations. While they both relate to the agricultural industry, the presence of genetically modified crops may have benefits for some corporations and locusts affect crop yields, but they do not have a direct correlation with each other. The other examples all illustrate financial risks that are correlated for the agricultural industry.

Question 8

A life insurance company will often require an applicant to submit to a brief physical exam to assess that person's basic level of health.This practice is a form of _____ to lessen the problem of _____.

Accepted Answer

The practice of conducting a physical exam is a form of screening, which is used to identify risky applicants to lessen the problem of adverse selection. Adverse selection occurs when insurance companies attract a disproportionate number of high-risk applicants, which can lead to higher costs and lower profits. By screening applicants, the insurance company can identify those with higher risk profiles and adjust premiums or exclude coverage to manage their risk. The other answer choices are not relevant to the scenario described in the question.

Question 9

Asymmetric,or private,information:

Accepted Answer

Asymmetric, or private, information refers to information that is relevant for an economic transaction and is known only by some of the people involved in the transaction. This can lead to one party having an advantage or disadvantage in the transaction due to their possession or lack of possession of the information.

Question 10

The strategy of investing in several assets so that any possible losses are independent events is:

Accepted Answer

Diversification is the strategy of investing in several assets so that any losses in one asset are not correlated with losses in other assets. By doing so, the investor can minimize their overall risk and maximize their chances of making a profit. This is considered a fundamental principle of investing and is widely accepted as a way to manage risk. Private information, moral hazard, and adverse selection are all different concepts that are not related to the strategy of diversification.

Question 11

Which strategy is NOT used for dealing with adverse selection in the labor market?

Accepted Answer

Openly asking candidates of any hidden work problems from their past is not a strategy for dealing with adverse selection because job applicants are unlikely to disclose negative information voluntarily. The other options listed (careful screening, examination of signals, and obtaining reference letters) are all strategies commonly used to address adverse selection in the labor market.

Question 12

People faced with adverse selection use _____ to deal with it.

Accepted Answer

People faced with adverse selection use a combination of screening, signals, and reputation to deal with it. Screening involves gathering information and conducting tests to screen out high-risk individuals. Signals are used by individuals to convey information about themselves to potential partners, such as education or job experience. Reputation refers to the established trustworthiness or reliability of an individual, institution or product. By using a combination of these strategies, individuals can mitigate the effects of adverse selection and reduce their risk of selecting a low-quality partner.

Question 13

Which factor is a limit to the ability of diversification to reduce risk?

Accepted Answer

The answer of Which factor is a limit to the...

Question 14

If relevant events are _____,diversification will NOT reduce risk.

Accepted Answer

When relevant events are positively correlated, diversification will not reduce risk. This is because when one asset is negatively affected by a relevant event, other assets in the portfolio are also likely to be negatively affected.

Question 15

Which pair of events is likely to be positively correlated?

Accepted Answer

A positive correlation means that as one event increases, the other is likely to increase as well. In the case of a week-long power outage due to a large hurricane, the demand for batteries is likely to increase as people seek alternative power sources, indicating a positive correlation between these two events.

Question 16

An individual can almost eliminate risk by taking a small share in many independent events or by taking advantage of the predictability associated with large numbers of independent events.This strategy is known as:

Accepted Answer

The mentioned strategy of taking a small share in many independent events or taking advantage of predictability associated with large numbers of independent events is known as pooling.

Question 17

The opportunity to engage in pooling shifts the _____ curve of insurance to the right;insurance companies will take on _____ risk and charge a _____ premium than without pooling.

Accepted Answer

Pooling allows insurance companies to spread risk across a larger group, enabling them to take on more risk at a lower premium, which increases the supply of insurance.

Question 18

At the end of the 1980s,Lloyd's of London was in severe financial trouble because of:

Accepted Answer

Lloyd's of London was hit hard by claims related to asbestos, which ultimately resulted in losses of over £10 billion for the insurance market.

Question 19

(Scenario: Diversification)Use Scenario: Diversification.If Morris invests half of his money in the sunglass company and half in the rain poncho company,what is his expected gain or loss? Scenario: Diversification
Morris is considering investing $10,000 in a sunglass company or a rain poncho company.If it is a rainy year and he invests only in the sunglass company,he will lose $5,000.However,if it is a rainy year and he invests only in the rain poncho company,he will earn $10,000.If it is a sunny year and he invests only in the sunglass company,he will earn $10,000;if he invests only in the rain poncho company,he will lose $5,000 in a sunny year.There is a 50% chance of a sunny year and a 50% chance of a rainy year.

Accepted Answer

If Morris invests half of his money in the sunglass company and half in the rain poncho company, his potential gains and losses would be:

- If it is a rainy year: he would earn $5,000 from the rain poncho company and lose $2,500 from the sunglass company (half of the $5,000 loss). So his total loss would be $2,500.
- If it is a sunny year: he would earn $5,000 from the sunglass company and lose $2,500 from the rain poncho company (half of the $5,000 loss). So his total gain would be $2,500.

Since there is a 50% chance of either a sunny or rainy year, we can calculate Morris's expected gain or loss by taking the average of both scenarios:

Expected gain or loss = (0.5 x $2,500) + (0.5 x (-$2,500)) = $0

Therefore, if Morris invests half of his money in each company, he should break even on average.

Question 20

If an insurance company insured 100,000 cars across the state against theft,which statement would NOT be true?

Accepted Answer

The insurance company cannot assume that very few cars will be stolen since theft is a common occurrence. The company can only estimate the expected number of thefts based on historical data and other relevant factors, but it cannot guarantee that very few cars will be stolen.
