Free Behavioral Economics Practice Sample Questions & Answers

Question 1. A consumer is choosing between two health insurance plans. Instead of comparing all available information, she focuses on a few easily noticeable features and chooses the first plan that meets her basic requirements. Which behavioral economics concept best explains this decision?

A. Perfect rationality

B. Bounded rationality

C. Loss aversion

D. Endowment effect

Correct Answer. B. Bounded rationality

Explanation: Bounded rationality describes decision-making when people face limits in information, time, attention, or cognitive processing. Rather than evaluating every possible alternative and calculating the optimal choice, individuals often simplify complex decisions by using manageable rules or stopping once they find an acceptable option. In this example, the consumer does not fully compare every insurance plan. She focuses on a limited set of features and selects an option that satisfies her basic requirements. This differs from perfect rationality, which assumes complete information and unlimited processing ability. Bounded rationality helps explain why real-world decisions often differ from predictions based on fully optimizing economic models.

Question 2. An investor refuses to sell a stock purchased for $80 even after its market value falls to $55 because selling would make the loss feel “real.” Which behavioral concept best explains this behavior?

A. Loss aversion

B. Anchoring

C. Availability heuristic

D. Present bias

Correct Answer. A. Loss aversion

Explanation: Loss aversion refers to the tendency for people to experience the psychological impact of losses more strongly than the satisfaction associated with comparable gains. In this situation, the investor may continue holding the stock because realizing a $25 loss feels particularly painful, even though the original purchase price should not determine the stock’s current value. The investor is effectively giving greater weight to avoiding the emotional experience of realizing a loss than to evaluating the investment based on its future prospects. Loss aversion is a central idea in prospect theory and helps explain why individuals sometimes hold losing investments longer than a purely rational financial analysis would suggest.

Question 3. During negotiations, a seller initially lists a used car at $24,000. Even after learning that similar cars typically sell for $20,000, the buyer continues to view prices near $22,000 as reasonable. Which bias is most evident?

A. Framing effect

B. Anchoring effect

C. Status quo bias

D. Self-serving bias

Correct Answer. B. Anchoring effect

Explanation: The anchoring effect occurs when an initial piece of information influences subsequent judgments, even when that information may not be objectively relevant to the decision. Here, the original $24,000 asking price serves as an anchor that affects the buyer’s later assessment of what constitutes a reasonable price. Although the buyer learns that comparable vehicles generally sell for around $20,000, the initial figure continues to influence the buyer’s expectations. Anchoring can occur in negotiations, pricing decisions, salary discussions, forecasts, and many other settings. The important feature is that an early reference point pulls later judgments toward itself.

Question 4. A restaurant describes a meal as “90% fat-free,” while another restaurant describes a similar meal as containing “10% fat.” Customers respond more favorably to the first description. Which concept does this illustrate?

A. Mental accounting

B. Framing effect

C. Endowment effect

D. Hyperbolic discounting

Correct Answer. B. Framing effect

Explanation: The framing effect occurs when people’s preferences change depending on how essentially equivalent information is presented. “90% fat-free” and “10% fat” communicate the same nutritional proportion, but the first description emphasizes the positive aspect while the second highlights the negative aspect. Behavioral economics shows that individuals do not always evaluate information independently of its presentation. The way a choice is described can influence attention, perception, and ultimately behavior. Framing effects can appear in advertising, medical decisions, financial communication, public policy, and everyday choices. The underlying options may remain unchanged while the presentation alters the decision.

Question 5. A person receives a $500 tax refund and places it into a special account for a vacation, even though she has outstanding credit-card debt with a high interest rate. Which concept best explains this behavior?

A. Mental accounting

B. Risk compensation

C. Representativeness

D. Anchoring

Correct Answer. A. Mental accounting

Explanation: Mental accounting refers to the tendency to mentally categorize money into separate accounts based on its source, intended purpose, or other psychological labels. In this example, the person treats the tax refund differently from other available funds by mentally assigning it to a vacation. From a purely financial perspective, using the refund to reduce high-interest credit-card debt might be more advantageous, but the psychological label attached to the money influences how it is used. Mental accounting helps explain differences in spending and saving behavior that cannot be fully explained by treating all money as completely interchangeable.

Question 6. A student plans to begin studying for an examination three weeks in advance. Each day, however, she chooses entertainment instead because the immediate enjoyment feels more important than the future benefit of being prepared. Which concept best describes this pattern?

A. Present bias

B. Anchoring

C. Endowment effect

D. Reciprocity

Correct Answer. A. Present bias

Explanation: Present bias describes the tendency to place disproportionately high value on immediate rewards or costs compared with consequences that occur in the future. The student understands that early studying would improve future exam preparation, but immediate entertainment repeatedly becomes more attractive when the choice is actually made. This behavior is closely related to time inconsistency and hyperbolic discounting, where the perceived value of future outcomes changes as they become more immediate. Present bias helps explain procrastination, insufficient saving, unhealthy consumption, and other situations in which people make choices that conflict with plans they previously intended to follow.

Question 7. An employer automatically enrolls new employees in a retirement savings plan but allows them to opt out at any time. Participation rises substantially compared with a system requiring employees to actively enroll. Which behavioral intervention is being used?

A. Price discrimination

B. Default option or nudge

C. Loss framing

D. Anchoring

Correct Answer. B. Default option or nudge

Explanation: A default option is the choice that takes effect automatically when an individual does not actively select an alternative. In this example, employees are enrolled in the retirement plan unless they choose to opt out. This is a common example of a nudge because the choice architecture influences behavior without removing the employee’s ability to make a different decision. The intervention takes advantage of people’s tendency to accept the status quo or avoid the effort involved in changing a preset option. Default effects are widely studied in behavioral economics and have applications in retirement saving, healthcare decisions, organ donation systems, and other policy settings.

Question 8. A highly experienced investor consistently overestimates his ability to predict short-term market movements and trades frequently despite repeated evidence that his forecasts are inaccurate. Which behavioral bias is most likely involved?

A. Overconfidence bias

B. Loss aversion

C. Availability heuristic

D. Endowment effect

Correct Answer. A. Overconfidence bias

Explanation: Overconfidence bias involves excessive confidence in one’s own knowledge, judgment, predictions, or ability to control outcomes. The investor has substantial experience but continues to believe that he can accurately predict short-term market movements despite evidence showing that his forecasts are unreliable. Overconfidence can lead people to underestimate uncertainty, trade too frequently, take excessive risks, or place too much weight on their own judgments. Experience does not automatically eliminate the bias. In financial decision-making, overconfidence is particularly important because markets contain substantial uncertainty and outcomes may depend on information that an individual cannot reliably predict.

Question 9. After seeing several news reports about a rare airplane accident, a traveler begins believing that flying is more dangerous than driving, even though statistical evidence shows otherwise. Which heuristic is most likely influencing the traveler?

A. Availability heuristic

B. Representativeness heuristic

C. Mental accounting

D. Reciprocity

Correct Answer. A. Availability heuristic

Explanation: The availability heuristic occurs when people estimate the likelihood of an event based partly on how easily examples come to mind. Because the traveler has recently seen vivid reports about airplane accidents, those events are especially accessible in memory. Their emotional impact and repeated media exposure can make the risk seem greater than statistical evidence suggests. The actual frequency of airplane accidents has not changed, but the ease with which examples can be recalled affects the person’s judgment. The availability heuristic can influence perceptions of crime, health risks, financial losses, natural disasters, and many other uncertain events.

Question 10. In an experiment, participants voluntarily give some of their earnings to another participant even when they receive no financial benefit for doing so. Which behavioral economics concept does this finding most directly challenge?

A. Self-interest as the only motivation for economic decisions

B. Bounded rationality

C. Hyperbolic discounting

D. Anchoring

Correct Answer. A. Self-interest as the only motivation for economic decisions

Explanation: Voluntary giving without a direct financial return suggests that people’s economic decisions can be influenced by social preferences rather than monetary self-interest alone. Behavioral economics examines motivations such as fairness, altruism, reciprocity, trust, and concern for others. These findings challenge the assumption that individuals always maximize their own immediate material payoff. A person may willingly sacrifice some income because they value helping another person or consider fairness important. Such behavior has been studied extensively through experimental economics and behavioral game theory. Social preferences therefore provide an important explanation for economic choices that cannot be fully captured by simple models of individual material self-interest.
