A researcher conducts a controlled experiment and finds that participants are significantly more likely to contribute to a group fund when their individual contributions are made public to the other participants. Based on the principle that behavior in such controlled settings can forecast actions in naturally occurring situations, which of the following is the most valid inference?

Evaluating the Predictive Power of Economic Experiments

The primary value of controlled economic experiments lies in their ability to establish theoretical principles, but their findings are generally considered to have little to no predictive power for behavior in real-world situations.

Match each finding from a controlled economic experiment with the real-world behavior it most likely predicts, demonstrating the predictive power of such experiments.

An economist is designing a controlled experiment to understand how social pressure influences charitable donations. Which of the following design choices would most likely increase the experiment's predictive power for forecasting donation behavior in naturally occurring situations?

Limitations of Predictive Power in an Experimental Design

A technology firm conducts a controlled experiment with a group of newly hired interns to test a new performance-based bonus system. In the experiment, the interns who receive the new bonus are 25% more productive on a data-entry task than those who do not. The firm's management concludes that implementing this bonus system company-wide for all employees will result in a 25% increase in overall productivity. Which of the following statements represents the most critical evaluation of this conclusion's reliance on the experiment's predictive power?

A city council wants to forecast how a new 'congestion charge' (a fee for driving downtown during peak hours) will affect traffic. They are considering several experimental designs to test the policy before a full-scale implementation. Which of the following designs is likely to have the highest predictive power for how the general population of drivers will behave?
