Interpreting Experimental Economic Data
In a controlled experiment, a group of four individuals is given the following task. Each person receives $20 and can, in private, contribute any amount from $0 to $20 to a group project. The total amount contributed to the project is then doubled by the experimenter and distributed equally among all four participants, regardless of how much each person individually contributed. After many rounds with different groups, the data shows that only 15% of participants contribute $0, and the average contribution is $9. Analyze these results. What do they suggest about the prevalence of purely self-interested behavior compared to the behavior predicted by a model where individuals only seek to maximize their own personal payoff?

An experiment is conducted where one person (the Proposer) is given $100 and must offer a portion to a second person (the Responder). If the Responder accepts the offer, the money is split as proposed. If the Responder rejects the offer, both individuals receive nothing. The purely self-interested prediction is that the Proposer will offer the smallest possible amount (e.g., $1) and the Responder will accept it, since $1 is better than $0. However, experiments consistently show that offers below $30 are frequently rejected by Responders. Which of the following statements best analyzes this common experimental outcome?

Interpreting Experimental Economic Data
The observation that participants in economic experiments often reject low, but positive, monetary offers demonstrates that the potential financial gain is the only factor influencing their decision-making process.
Reconciling Economic Theory with Experimental Observations
In economic experiments, participants exhibit various behaviors that challenge the assumption of pure self-interest. Match each described behavior with the primary motivation it most strongly suggests.
Designing a Community Contribution System
An economist conducts an experiment where one person (the 'Proposer') is given a sum of money and must offer a portion to a second person (the 'Responder'). If the Responder accepts, they split the money as proposed; if they reject, neither gets anything. The experiment is run twice: first with a total of $10 and then with a total of $1,000. Based on robust findings from similar experiments, what is the most likely change in behavior when the stakes are increased from $10 to $1,000?
Evaluating the 'High-Stakes' Critique of Behavioral Findings
Experimental results from economic games, where many participants make choices that benefit others at a personal cost or reject unfair distributions, indicate that purely self-interested behavior is often a ________ behavior, rather than the universal norm predicted by some traditional models.
