Public Economics
Randomized controlled trials (RCTs) are research studies that randomly assign participants into two or more groups to test the effects of a treatment, intervention, or policy. By controlling for external variables and ensuring that each participant has an equal chance of being assigned to any group, RCTs provide strong evidence about causality and effectiveness. This method is particularly valuable in evaluating public policy interventions, assessing behavioral nudges, and analyzing the impacts of tax and welfare programs.
