The randomized controlled trial (RCT) has been a heavily utilized research tool in medicine for over 60 years. Since the early 2000's, large-scale RCTs have been used in increasingly large numbers in the social sciences to evaluate questions of both policy and theory. The early economics...

Lab experiments are an increasingly valuable tool for understanding differences in how men and women are treated in the labour market. Dr Ghazala Azmat and Professor Barbara Petrongolo explore what has been learned about the extent to which differences in men and women's pay and employment...

We overview the use of field experiments in labor economics. We showcase studies that highlight the central advantages of this methodology, which include: (i) using economic theory to design the null and alternative hypotheses; (ii) engineering exogenous variation in real world economic...

We test for gender discrimination by sending fake CVs to apply for entry-level jobs. Female candidates are more likely to receive a callback, with the difference being largest in occupations that are more female-dominated.

We present results from a field experiment testing the gift-exchange hypothesis inside a tree-planting firm paying its workforce incentive contracts. Firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attributable to past planting...

We review experimental evidence collected from risky choice experiments using poor subjects in Ethiopia, India and Uganda. Using these data we estimate that just over 50% of our sample behaves in accordance with expected utility theory and that the rest subjectively weight probability according...

This study reports data from a field experiment that was conducted to investigate the relevance of gift-exchange for charitable giving. Roughly 10,000 solicitation letters were sent to potential donors in the experiment. One third of the letters contained no gift, one third contained a small...

We discuss the contribution of the experimental literature to the understanding of both traditional and previously unexplored dimensions of gender differences and discuss their bearings on labor market outcomes. Experiments have offered new findings on gender discrimination, and while they have...

We conduct a controlled lab-field experiment to directly test the short-run spillover effects of one-off financial incentives in health. We consider how incentives affect effort in a physical activity task - and then how they spillover to subsequent eating behaviour. Compared to a control group,...
