Which of the following are true of statistical discrimination? There may be more than one correct answer. "Ban the box" laws not allowing employers to ask potential employees whether or not they have been in jail is increasing discrimination against Black men, particularly those without a college degree. Statistical discrimination occurs when firms base hiring decisions on which candidate will improve the firm's diversity statistics. Some employers run complex statistical analysis of candidates' resumes before deciding who to interview for a position. Statistical discrimination occurs when employers discriminate against job candidates based on an irrelevant but observable characteristic which correlates to an unmeasurable but relevant characteristic.

Alena manages a small theme park. She hires one more custodian at $450 per week, and her park is cleaner and more attractive. As a result of this improvement, ticket sales rise by 40 tickets per week. Tickets sell for $12. Use the Rational Rule for Employers to determine if hiring the extra custodian was a good move. No, it was a bad move because it added more to cost than revenue. Yes, it was a good move because the ticket sales rose more than price. Yes, it was a good move because it added more to revenue than to cost. No, it was a bad move because price did not rise as much as ticket sales.

Which of the following statements describes the Coase Theorem? even if bargaining is not costless, and property rights are unclear, externality problems can be solved through private bargaining if the marginal benefit of a good exceeds the good's marginal cost, more of it should be produced elimination of an externality is possible only when the marginal benefit of a good is no higher than its marginal cost if bargaining is costless, and property rights are clearly established and enforced, then externality problems can be solved through private bargaining

The Nobel Prize‑winning economist Oliver Hart once said, "If we know the marginal social cost [of pollution] emissions, a tax is better, but if we know the optimal quantity, cap and trade is better." Given this statement and the knowledge of ways governments can intervene in markets, evaluate the following statement: Any outcome that can be achieved by taxing can also be accomplished by establishing a quota. This is because: if we know the marginal social cost, we can set the tax so that price is equal to the optimal price. As a result, the optimal quantity will be achieved. If we know the optimal quantity, we can set a quota and the market will find the optimal price. if we know the optimal quantity, cap and trade can be used to set the price. If we know the marginal social cost, a tax can be used to set the quantity. if we know the marginal social cost, we can set the optimal quantity equal to the optimal price. If we know the optimal quantity, we can set a quota equal to the optimal price. knowing the marginal social cost allows companies to know how much to increase their prices and make more profits. This is better for the economy as a whole because then companies can create more jobs. Cap and trade restricts quantity, which lowers profits.

if we know the marginal social cost, we can set the tax so that price is equal to the optimal price. As a result, the optimal quantity will be achieved. If we know the optimal quantity, we can set a quota and the market will find the optimal price.
