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

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 vi
