Evidence from social psychology suggests that agents process information about their own ability in a biased manner. This evidence has motivated exciting research in behavioral economics, but has also garnered critics who point out that it is potentially consistent with standard Bayesian...

Anti-poverty programs in developing countries are often difficult to implement; in particular, many governments lack the capacity to deliver payments securely to targeted beneficiaries. We evaluate the impact of biometrically-authenticated payments infrastructure ("Smartcards") on beneficiaries...

We seed noisy information to members of a real-world social network to study how information diffusion and information aggregation jointly shape social learning. Our environment features substantial social learning. We show that learning occurs via diffusion which is highly imperfect: signals...

This paper builds a theory of informal contract enforcement in social networks. In our model, relationships between individuals generate social collateral that can be used to control moral hazard when agents interact in a borrowing relationship. We define trust between two agents as the maximum...

The division of labor first increased during industrialization and then decreased again after 1970 as job roles have expanded. We explain these trends in the organization of work through a simple model where (a) machines require standardization to exploit economies of scale and (b) more...

We develop a model of informal risk-sharing in social networks, where relationships between individuals can be used as social collateral to enforce insurance payments. We characterize incentive compatible risk-sharing arrangements and obtain two results. (1) The degree of informal insurance is...

This paper summarizes research on gender differences in economic settings. I discuss gender differences in attitudes toward competition, altruism and the closely related issue of cooperation, and risk preferences. While gender differences in competition are large and robust, the results are much...

Experimental tests of dynamically inconsistent time preferences have largely relied on choices over time-dated monetary rewards. Several recent studies have failed to find the standard patterns of time inconsistency. However, such monetary studies contain often discussed confounds. In this...

Gender differences in competitiveness are often discussed as a potential explanation for gender differences in education and labor market outcomes. We correlate an incentivized measure of competitiveness with an important career choice of secondary school students in the Netherlands. At the age...

Markets sometimes unravel, with offers becoming inefficiently early. Often this is attributed to competition arising from an imbalance of demand and supply, typically excess demand for workers. However this presents a puzzle, since unraveling can only occur when firms are willing to make early...
