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:

1. 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.
2. 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?
