Laboratory Experiments on Cooperation in the Prisoners' Dilemma
In addition to observing behavior in naturally occurring situations, economists utilize controlled laboratory experiments to analyze why individuals might choose to cooperate in prisoners' dilemma scenarios instead of defecting, as predicted by models of pure self-interest.

Evaluating Predictions of Economic Models
Two firms in the same market face a choice: they can either cooperate by setting a high price for their product, leading to a good shared profit, or one can undercut the other by setting a low price to capture the whole market, which is better for them individually but worse for the other firm. Match each contextual factor below with its most likely impact on the firms' decision to cooperate.
According to standard economic models that assume all individuals act solely out of self-interest, the frequent observation of cooperation in situations where defection would yield a higher individual payoff is an expected and predictable outcome.
Two competing coffee shops are located next to each other. Each shop has the choice to either set a high price for their coffee or a low price. If both set a high price, they both make a moderate profit. If one sets a low price while the other sets a high price, the low-price shop captures most of the market and makes a large profit, while the high-price shop makes a loss. If both set a low price, they engage in a price war and both make a very small profit. Economic models based on pure self-interest predict that both shops will set a low price. However, in reality, both shops are observed maintaining a high price. Which of the following provides the most plausible explanation for this cooperative outcome?

Altruism as a Solution to Social Dilemmas
Consider a strategic situation involving two individuals where mutual cooperation leads to a good outcome for both, but an individual can achieve an even better personal outcome by defecting while the other cooperates. If both defect, they both end up with a poor outcome. Economic models assuming pure self-interest predict that both individuals will defect. However, in reality, cooperation is often observed. How does the presence of altruism (a genuine concern for the welfare of others) explain this cooperative behavior?

Interpreting Experimental Economic Data
An economist develops a new theory about how individuals decide whether to contribute to a shared resource. What is the primary reason for using a controlled laboratory experiment to investigate this theory?
Designing an Experiment to Test Fairness
Match each key feature of a controlled economic experiment with its primary purpose in understanding human decision-making.
A researcher conducts an experiment where participants are given $10 and can anonymously give any amount to a stranger. Most participants give some money away. A critic argues this result is meaningless for understanding real-world economics because the experiment takes place in an artificial lab, not in a real market. The critic's argument is valid because the primary goal of such economic experiments is to perfectly replicate naturally occurring situations.

Evaluating an Experimental Design
In a controlled experiment, two anonymous participants are assigned roles. Player 1 is given $20 and must propose how to split it with Player 2. Player 2 can either accept the proposed split, in which case both players are paid accordingly, or reject it, in which case both players receive nothing. The most common proposal from Player 1 is a $10/$10 split, and proposals where Player 1 offers less than $5 are almost always rejected by Player 2. What is the most logical conclusion that can be drawn from these results?
An economist wants to study how small-scale farmers decide whether to adopt a new, more expensive but potentially more profitable type of seed. They are considering two research methods:
- Method A: A controlled experiment in a university computer lab where farmers are given information and a sum of money, and they play a game that simulates the risks and rewards of choosing the new seed versus their traditional seed.
- Method B: A field study where a random group of farmers in a village is offered a discount on the new seed, and their adoption rate is compared to another random group in the same village that was not offered the discount.
Which statement best evaluates the primary trade-off between these two methods for understanding the farmers' decision-making?

Interpreting Experimental Game Results
An economist designs a study where two anonymous participants, who will only interact once, must independently choose one of two actions: 'Action A' or 'Action B'. The outcomes are set up so that choosing 'Action B' always yields a higher personal payoff for an individual, regardless of the other participant's choice. However, if both participants choose 'Action A', they each receive a better payoff than if they both choose 'Action B'. What is the primary research question this experimental design is best suited to investigate?
Theoretical Predictions vs. Experimental Observations
An economist conducts a study where participants play a game with a partner. In the game, each player can choose to either 'cooperate' or 'not cooperate'. The payoffs are structured such that not cooperating always yields a higher individual reward for that round, regardless of the partner's choice, but mutual cooperation leads to a better outcome for both than mutual non-cooperation. The study compares two conditions:
- Condition 1: Participants play the game only once with an anonymous partner.
- Condition 2: Participants play the game for ten consecutive rounds with the same partner.
The results show that the rate of cooperation is significantly higher in Condition 2 than in Condition 1. Which of the following is the most robust explanation for this finding?
Critiquing an Experimental Design
Designing an Experiment to Test a Hypothesis
An economist studies a game where two individuals can either 'cooperate' or 'defect'. Defecting always yields a higher personal payoff for that round, but mutual cooperation is better for both than mutual defection. Match each experimental condition below with the primary factor that would explain a player's decision to cooperate in that scenario.
An economist observes that in a one-time, anonymous interaction where two participants can choose to either 'cooperate' or 'defect', a certain percentage of participants choose to 'cooperate'. If the experiment is modified so that participants are first shown a brief, neutral video of their anonymous partner, economic theory predicts this change will decrease the rate of cooperation.
Predicting Experimental Outcomes in a Cooperation Game
An economist conducts an experiment where pairs of anonymous participants play a game one time. In this game, each player can choose to either 'cooperate' or 'defect'. Defecting always provides a higher individual payoff for that round, but if both players cooperate, they achieve a better outcome than if they both defect. The experiment has three conditions:
- Condition 1 (Control): Participants are given no information about their partner. The cooperation rate is 25%.
- Condition 2 (In-Group): Participants are told their partner is a student from their own university. The cooperation rate is 40%.
- Condition 3 (Out-Group): Participants are told their partner is a student from a rival university. The cooperation rate is 10%.
Based on these results, what is the most precise conclusion an economist can draw?
