- The conclusion that the cash bonus caused the lower healthcare costs is potentially flawed because of...
Answer: a self-selection bias, as employees who are already healthy are most likely to join the program.
This is a classic correlation vs. causation problem driven by self-selection. The employees who are most likely to sign up for a gym incentive program are those who already enjoy exercise and lead a healthy lifestyle. They are simply being paid for behavior they would likely engage in anyway. Therefore, the program may not be causing them to be healthy, but rather, their pre-existing healthiness is causing them to participate. The lower healthcare costs may be correlated with participation, but not necessarily caused by it.
- This tax policy creates a financial incentive that...
Answer: lowers the relative cost of owning a home compared to renting, thereby encouraging homeownership.
A tax deduction reduces a person's overall tax liability. By allowing mortgage interest to be deducted, the government is effectively subsidizing homeownership. This makes the after-tax cost of owning a home lower than it would be otherwise. This policy creates a clear incentive to own rather than rent, as renters do not receive a similar tax benefit for their housing payments.
- The primary way this policy uses incentives to change behavior is by...
Answer: increasing the opportunity cost of driving during peak hours, encouraging substitutes like off-peak travel or carpooling.
This policy, known as congestion pricing, is a negative incentive. It does not directly subsidize alternatives (A), but it makes the choice to drive during peak hours more expensive. This increases the opportunity cost of that choice. In response, rational individuals are incentivized to seek substitutes, such as shifting their travel to off-peak times, using public transport, or carpooling, all of which help reduce congestion. While it does generate revenue (D), its primary behavioral purpose is to alter choices at the margin.
- What is the most likely secondary effect of this policy on the market for traditional, non-solar roofing contractors?
Answer: They will face decreased demand as some homeowners opt for a solar installation instead of a traditional roof repair or replacement.
The tax credit acts as an incentive that makes solar panels a more attractive substitute for traditional roofing options, especially for homeowners who were already considering a roof replacement. By lowering the relative price of the solar option, the policy diverts some consumer spending away from traditional contractors, thus decreasing demand for their services. This requires a two-step reasoning: understanding the incentive and then identifying its effect on a related market.
- What incentive does this pending law create for landowners in the year before it takes effect?
Answer: A perverse incentive to preemptively destroy potential habitats to avoid the future land-use restrictions.
This is often called the 'shoot, shovel, and shut up' problem. The impending regulation acts as a powerful negative incentive. For a landowner, the presence of the endangered species' habitat will result in a significant financial loss (the inability to develop the land). To avoid this outcome, a rational landowner is incentivized to eliminate any potential habitat before the law takes effect, thereby ensuring the regulation will not apply to them. This is a perverse incentive that works directly against the policy's goals.
- This policy creates a direct financial incentive for a factory manager to...
Answer: invest in pollution-abatement technology only if its marginal cost is less than the marginal fine for polluting.
This policy works by making pollution costly at the margin. A rational factory manager will compare the cost of reducing one more ton of pollution (the marginal abatement cost) with the cost of emitting that ton (the fine). They will choose to reduce pollution up to the point where the cost of further reduction equals the fine. If the technology to reduce pollution is cheaper than the fine, they will invest in it. This is an application of marginal analysis to incentives.
- How does this incentive structure most likely affect the behavior of a salesperson who has made 95 sales with one week left in the quarter?
Answer: It will provide a very strong incentive to exert maximum effort to make the final 5 sales.
This 'all-or-nothing' or 'threshold' bonus creates a massive marginal incentive as a salesperson approaches the target. The difference between the 99th and 100th sale is not just one sale, but the entire bonus amount. Therefore, a salesperson who is very close to the threshold will be highly motivated to do whatever it takes to get over the line. Shifting sales to the next quarter (D) would mean forfeiting the large bonus.
- Which statement provides the most accurate economic comparison of these two incentive structures?
Answer: Structure 2 is more likely to incentivize the development of commercially viable products that benefit the company.
Structure 1 incentivizes an intermediate output (patents), which may or may not have commercial value. This could lead the team to file many low-quality patents. Structure 2, however, ties the incentive directly to the ultimate goal of the company: profitability. This better aligns the interests of the R&D team (the agents) with the interests of the company (the principal), encouraging them to focus on research that leads to successful products.
- Given the structure of the CEO's compensation, which project is the CEO most incentivized to choose, and why?
Answer: Project B, because the incentive structure encourages prioritizing short-term gains that directly affect the CEO's immediate compensation.
The CEO's incentive is based on a short-term metric (annual stock price). This creates a strong personal incentive to favor actions that yield immediate, visible results, even if they are detrimental to the company's long-term health. Project B aligns with this short-term incentive, while Project A's benefits are too far in the future to affect the CEO's current bonus. This highlights a common conflict between short-term and long-term incentives.
- This discount is primarily designed to mitigate the problem of moral hazard by...
Answer: creating a financial incentive for drivers to act more cautiously than they otherwise might if fully insured.
Moral hazard is the tendency for an insured person to take on more risk because they are protected from the full costs of that risk. The 'Good Driver Discount' counteracts this by creating a positive financial incentive (a lower premium) for avoiding accidents. This encourages the policyholder to drive more carefully, aligning their behavior more closely with the interests of the insurer. Choice A describes a strategy to combat adverse selection, not moral hazard.
- Which economic concept best explains this counterintuitive result?
Answer: The introduction of a financial penalty crowded out the parents' intrinsic motivation, such as guilt or social obligation, to be on time.
This scenario illustrates the 'crowding out' effect. Before the fine, the incentive to be on time was largely non-financial (a moral or social duty not to inconvenience the staff). By introducing a fine, the daycare turned being late into a market transaction—parents could now 'buy' the right to be late. For many, paying a small fee assuaged their guilt, making them more likely to be late than before. Choice B is an incomplete explanation; it doesn't explain why tardiness increased rather than just staying the same. Choices A and D use economic terms incorrectly in this context.
- From a purely economic incentive standpoint, one significant potential disadvantage of the tenure system is that it may...
Answer: reduce the motivation for a professor to maintain high levels of productivity after tenure has been granted.
The core critique of tenure as an incentive is that by removing the threat of being fired for poor performance, it can weaken the motivation to continue producing high-quality research and teaching. Once the 'prize' of tenure is won, the extrinsic incentive for high productivity is significantly reduced. Choices A and C describe incentive effects before tenure is granted. Choice D describes a potential self-selection issue, but B addresses the change in incentives for an individual after the event.
- This policy creates the strongest incentive for teachers to focus their efforts on...
Answer: narrowly tailoring their curriculum to the specific subjects and formats covered by the standardized test.
The incentive is tied to a very specific, narrow metric: standardized test scores. To maximize their chances of receiving the bonus, teachers are rationally incentivized to 'teach to the test.' This means focusing classroom time and effort on the material most likely to appear on the exam and on test-taking strategies, potentially neglecting broader educational goals like creativity or in-depth understanding of other topics.
- From the perspective of incentivizing recycling behavior, why is Proposal B likely to be more effective than Proposal A?
Answer: Proposal B reframes the 10 cents as the consumer's own money to be reclaimed, creating a stronger sense of loss aversion if the bottle is not returned.
While both proposals alter the cost by 10 cents, they frame the incentive differently. The deposit system (Proposal B) leverages the psychological principle of loss aversion. Once the consumer has paid the deposit, they view that 10 cents as their own money. The desire to avoid the loss of their money is a powerful motivator to return the bottle. A tax (Proposal A) is simply part of the price and lacks this strong psychological hook to perform a specific action (returning the bottle) after the purchase.
- Compared to the individual commission system, this new incentive structure is more likely to create which potential problem?
Answer: The free-rider problem, where some individuals exert less effort because they can still benefit from the work of others.
In a team-based reward system, the direct link between an individual's effort and their reward is weakened. This creates a free-rider problem, where a rational individual may be tempted to shirk their responsibilities, knowing that the negative impact of their reduced effort is spread across the entire group, while they still receive an equal share of the reward. Choice B is a common problem with individual commissions, which the new plan is meant to solve.
- The practice of tipping primarily serves to align incentives in this principal-agent relationship by...
Answer: creating a direct, performance-based reward for servers that is funded and evaluated by the customers.
This is a classic example of a solution to the principal-agent problem. The owner wants excellent service but can't watch every interaction. Tipping outsources the monitoring and reward function to the customer. Because better service generally leads to better tips, the server (agent) is incentivized to act in the best interest of the customer, which in turn benefits the owner (principal) through repeat business. While tipping does shift some wage costs (A), its primary function as an incentive is to link performance to pay.
- This outcome suggests that consumer behavior was effectively influenced by...
Answer: a non-financial, social incentive related to peer comparison and conformity.
Since the price of water did not change, the incentive that altered behavior was not financial. The new information provided—comparison to neighbors—taps into powerful social incentives. People are often motivated by a desire to conform to social norms, to compete, or to not appear wasteful compared to their peers. This demonstrates that non-financial and social information can be potent incentives for changing behavior.
- How does this vesting period serve as an incentive for employee retention?
Answer: It acts as a 'golden handcuff,' increasing the opportunity cost of leaving the company before the five-year period is over.
Stock options that vest over time are a form of deferred compensation. An employee who leaves before the vesting period is complete forfeits a potentially large amount of money. This creates a significant opportunity cost for leaving the firm, effectively acting as 'golden handcuffs' that bind the employee to the company. The incentive is to stay long enough for the options to vest. The options are not immediate cash (B) and do not encourage a short-term focus (D), but rather a long-term one.
- This incentive is most likely to inadvertently encourage employees to...
Answer: prioritize quantity over quality, closing tickets quickly without fully resolving the customer's issue.
When an incentive measures and rewards one dimension of performance (quantity of tickets closed), employees are incentivized to maximize that dimension, often at the expense of other, unmeasured dimensions (like quality of service). This can lead to employees providing quick, incomplete fixes or rushing customers off the phone to improve their numbers, which ultimately harms customer satisfaction. This is a classic example of the adage, 'You get what you measure.'
- Which of the following describes the most likely unintended consequence of this incentive structure?
Answer: Entrepreneurs will begin breeding rats in captivity to humanely kill them and collect the bounty.
This is a classic example of a perverse incentive, often called the 'cobra effect.' The policy is intended to decrease the rat population, but it creates a financial incentive to increase the supply of rats to collect the bounty. This leads to the unintended consequence of people farming the very thing the policy was meant to eliminate. Choice A is a possible outcome but relates to the effectiveness of the incentive, not a perverse or unintended consequence. Choice B is an unlikely outcome. Choice D describes the intended goal, which is unlikely to be fully realized and ignores the potential for negative consequences.
