Evaluating Experimental Design for Policy Recommendations

An economist wants to conduct an experiment to test the effectiveness of a new tiered pricing system designed to encourage water conservation among households in a city currently experiencing a severe drought. To ensure the study's findings are most directly applicable for local policymakers, which of the following groups would be the most appropriate to recruit as participants?

Comparing Participant Groups in Economic Experiments

Evaluating Participant Selection in Economic Research

A primary advantage of using a general student population instead of real-world stakeholders in a field experiment is that the results will have greater direct applicability to the specific real-world problem being studied.

An economist is designing several field experiments to study different real-world problems. Match each research problem with the most appropriate group of real-world stakeholders to recruit as participants to ensure the findings are directly applicable.

Justifying Participant Selection in a Field Experiment

A research team is studying the impact of a new microloan program on the business success of street vendors in a large city. They conduct an experiment by offering the loans to a randomly selected group of actual street vendors from that city and tracking their sales over six months. What is the primary advantage of this participant selection strategy?

Critiquing an Experimental Design for Studying Farmer Behavior

A government agency wants to design a new tax incentive to encourage small businesses to hire more employees. They are considering two research proposals to test the incentive's effectiveness. Proposal X involves a laboratory experiment where university students are given a hypothetical business scenario and asked how they would respond to the tax incentive. Proposal Y involves a field experiment where a random sample of actual small business owners are offered the real tax incentive, and their subsequent hiring decisions are tracked. Why would the findings from Proposal Y be more valuable for the agency's policy decision?
