Computers are an important part of modern education, yet many schoolchildren lack access to a computer at home. We test whether this impedes educational achievement by conducting the largest-ever field experiment that randomly provides free home computers to students. Although computer ownership...

Household investment in preventative health products is low in developing countries even though benefits from these products are very high. What interventions most effectively stimulate demand? In this paper, we experimentally estimate demand curves for health products in Kenya, Guatemala,...

Many studies suggest that daily income earners behave as if they have daily income targets. Less work has examined the determinants of the targets themselves. Using data on labor supply, shocks, and self-reported cash needs from 257 bicycle taxi drivers in Western Kenya, we provide evidence that...

While many developing-country policymakers see heavy fertilizer subsidies as critical to raising agricultural productivity, most economists see them as distortionary, regressive, environmentally unsound, and argue that they result in politicized, inefficient distribution of fertilizer supply. We...

Does limited access to formal savings services impede business growth in poor countries? To shed light on this question, we randomized access to non-interest-bearing bank accounts among two types of self-employed individuals in rural Kenya: market vendors (who are mostly women) and men working...

Most people in rural Africa do not have bank accounts. In this paper, we combine experimental and survey evidence from Western Kenya to document some of the supply and demand factors behind such low levels of financial inclusion. Our experiment had two parts. In the first part, we waived the...

Using data from a field experiment in Kenya, we document that providing individuals with simple informal savings technologies can substantially increase investment in preventative health and reduce vulnerability to health shocks. Simply providing a safe place to keep money was sufficient to...

In the 1980s, many U.S. cities initiated programs reserving a proportion of government contracts for minority-owned businesses. The staggered introduction of these set-aside programs is used to estimate their impacts on the self-employment and employment rates of African-American men. Black...

Previous studies tend to find that immigration has a weak negative effect on the employment and earnings of native-born workers. These studies overlook the effect of immigration on an important sector of the labor force, the self- employed. Anecdotal evidence suggests that immigrants, especially...

We examine trends in self-employment among white and black men from 1910 to 1990 using Census and CPS microdata. Self-employment rates fell over most of the century and then started to rise after 1970. For white men, we find that the decline was due to declining rates within industries, but was...
