What is the effect of exposing motivated youth to firm management in practice? To answer this question, we place young professionals for one month in established firms to shadow middle managers. Using random assignment into program participation, we find positive average effects on wage...

We conduct a clustered randomized controlled trial across 180 villages in Uttar Pradesh, India, to promote the take-up of a savings commitment product newly introduced to our study population. A random subset of participants was targeted through our promotional campaign to test whether the...

We experimentally test two seminal hypotheses on the impact of competition on firms' management upgrading. In a first experiment, we protect firms from labor market competition by reducing the risk that a freshly trained manager would be poached by a rival firm. We find that this protection does...

This paper surveys research on social capital. We explore the concepts that motivate the social capital literature, efforts to formally model social capital using economic theory, the econometrics of social capital, and empirical studies of the role of social capital in various socioeconomic...

We conduct a large scale RCT to investigate peer effects in computer assisted learning (CAL). Identification of peer effects relies on three levels of randomization. It is already known that CAL improves math test scores in Chinese rural schools. We find that paired treatment improves the...

Experimental evidence to date supports the double theoretical prediction that parties transacting repeatedly punish bad contractual performance by reducing future offers, and that the threat of punishment disciplines opportunistic breach. We conduct a repeated gift-exchange experiment with...

We formalize a noted [Guryan et al., 2009] but unexplored source of bias in peer effect estimation, arising because people cannot be their own peer. We derive, for linear-in-means models with non-overlapping peer groups, an exact formula of the bias in a test of random peer assignment. We...

We conduct a randomized evaluation of two job-search support programs for urban youth in Ethiopia. One group of treated respondents receives a subsidy to cover the transport costs of job search. Another group participates in a job application workshop where their skills are certified and they...

Using a large administrate dataset covering the universe of phone calls and airtime transfers in a country over a four year period, we examine the pattern of adoption of airtime transfers over time. We start by documenting strong network effects: increased usage of the new airtime transfer...

We discuss a method aimed at reducing the risk that spurious results are published. Researchers send their datasets to an independent third party who randomly generates training and testing samples. Researchers perform their analysis on the former and once the paper is accepted for publication...
