Social media permeates many aspects of our lives, including how we connect with others, where we get our news and how we spend our time. Yet, we know little about the economic effects for users. In 2017, we ran a large field experiment with over 1,765 individuals to document the value of...

We implement a risk experiment that allows for judgment errors to investigate who makes mistakes and whether it matters. The experiments are conducted with a random sample of the adult population in Rwanda, and survey data is collected on the usage of financial instruments that serve as...

Donating to charity requires time, effort and attention. If the nuisance costs to give are perceived to be large, charities may lose out on donations. We develop a non-parametric test for the presence of these costs and conduct a large-scale field experiment on giving to show that nuisance costs...

This paper develops a novel field experiment to test the implicit prediction of tournament theory that competition increases work time and can therefore contribute to the long work hours required in elite occupations. A majority of workers in the treatment without explicit financial incentives...

We investigate the consistency and stability of individual risk preferences by manipulating cognitive resources. Participants are randomly assigned to an experiment session at a preferred time of day relative to their diurnal preference (circadian matched) or at a non-preferred time (circadian...

We investigate the distribution of risk preferences and the frequency of expected utility violations along the gradient of market development. To do this, we collect experimental and survey data from a random sample of the population at four sites in Peru that differ in their level of...

We explore the importance of appearance in group formation using a series of experiments with a non-student population of mixed racial heritage. In order to test for discrimination, we ask subjects to choose partners. We manipulate the amount of payoff-relevant information on behavior, thereby...

One of the reasons why market economies are able to thrive is that they exploit the willingness of entrepreneurs to take risks that laborers might prefer to avoid. Markets work because they remunerate good judgement and punish mistakes. Indeed, modern contract theory is based on the assumption...
