Offer Structure in the Kenyan/US Ultimatum Game Experiment
In the ultimatum game experiment comparing Kenyan farmers and US students, Proposers were restricted to a specific set of six possible offers. They could propose to give the Responder 0%, 10%, 20%, 30%, 40%, or 50% of the total pie.

Comparison of Proposer Offers: Kenyan Farmers vs. US Students
Disentangling Cultural, Occupational, and National Influences in Ultimatum Game Behavior
In an economic experiment, a 'Proposer' offers a split of a sum of money to a 'Responder'. If the Responder accepts, they both get the money as proposed; if the Responder rejects, both get nothing. When comparing US students and Kenyan farmers as Responders, researchers found that while a 50% offer was accepted by nearly everyone, farmers were far more likely than students to reject offers of 30% or less. Which of the following statements best analyzes the behavior of the Kenyan farmers?
Interpreting Economic Behavior
Critiquing Interpretations of Economic Experiments
Consider a bargaining scenario where a 'Proposer' offers a split of a sum of money, and a 'Responder' can either accept the deal or reject it, in which case neither person gets anything. In a study comparing two distinct cultural groups, Group A (Kenyan farmers) was far more likely to reject low offers (e.g., 20% of the total sum) than Group B (US students). Based on this outcome, one can definitively conclude that individuals in Group A are less motivated by personal monetary gain than individuals in Group B.
Explaining Behavioral Differences in Economic Games
In a bargaining scenario, a 'Proposer' offers to split a sum of money with a 'Responder'. The Responder can accept the offer, or reject it, in which case neither person receives anything. An experiment found that while almost all participants from both groups accepted a 50% offer, Kenyan farmers were much more likely to reject a low offer (e.g., 20%) than US students. A critic of the study argues, 'This result simply shows that the farmers are irrational because any rational person would accept any amount of money rather than get nothing.' Which of the following provides the strongest counter-argument to this critic's claim?
In a one-shot bargaining game, a 'Proposer' offers a split of a sum of money, and a 'Responder' can accept or reject it. If rejected, neither party gets anything. An experiment compared two culturally distinct groups of Responders, 'Group A' and 'Group B'. Match each behavioral pattern observed in the experiment to its most likely underlying driver.

In an economic experiment, a 'Proposer' was given a sum of money and could offer a portion of it to a 'Responder'. The only offers the Proposer was allowed to make were 0%, 10%, 20%, 30%, 40%, or 50% of the total sum. Researchers observed that Responders from a rural farming community were significantly more likely to reject offers below 40% than Responders from a university student population. Based only on the described structure of the experiment, which of the following conclusions about the Responders' behavior is impossible to validate?
Evaluating Experimental Design in a Bargaining Game
In an economic experiment, a 'Proposer' could offer a 'Responder' one of six specific portions of a total sum: 0%, 10%, 20%, 30%, 40%, or 50%. Based on this design, if a researcher observes that a Responder from a particular group never rejected a 30% offer, they can confidently conclude that this Responder would have also accepted a 25% offer.
Interpreting Bargaining Experiment Data
Implications of Experimental Design in a Bargaining Game
In an economic experiment, a 'Proposer' must decide how to split a sum of money with a 'Responder'. The Proposer is only allowed to offer one of the following percentages of the total sum to the Responder: 0%, 10%, 20%, 30%, 40%, or 50%. If the Responder rejects the offer, both receive nothing. The Proposer believes that any offer below 40% is almost certain to be rejected. Which statement best analyzes the Proposer's strategic dilemma given these constraints?
Evaluating Experimental Design Limitations
In a bargaining experiment, Proposers were restricted to offering Responders one of six specific percentages of a total sum: 0%, 10%, 20%, 30%, 40%, or 50%. After collecting data from many pairs, a researcher reports that the average accepted offer was 38%. What is the most accurate interpretation of this finding?
In a bargaining experiment, a 'Proposer' is given $100 and must make a take-it-or-leave-it offer to a 'Responder'. The Proposer is restricted to offering one of the following amounts: $0, $10, $20, $30, $40, or $50. If the Responder rejects the offer, both participants receive $0. The Proposer estimates the probability that the Responder will reject each offer as follows:
- $0 offer: 100% rejection probability
- $10 offer: 80% rejection probability
- $20 offer: 60% rejection probability
- $30 offer: 40% rejection probability
- $40 offer: 10% rejection probability
- $50 offer: 0% rejection probability
To maximize their own expected earnings, which offer should the Proposer make?
In a bargaining experiment, Proposers were limited to offering the Responder one of six specific percentages of a total sum: 0%, 10%, 20%, 30%, 40%, or 50%. Which of the following provides the most compelling methodological justification for imposing this restriction, as opposed to allowing any offer between 0% and 50%?
