Regular use of effective health-products such as insecticide-treated mosquito nets (ITN) by a household benefits its neighbors by (a) reducing chances of infection and (b) raising awareness about product-effectiveness, thereby increasing product-use. Due to their potential social benefits and...

We conducted a randomized trial among 14,545 households in rural Burkina Faso to test the oft-cited hypothesis that limited access to contraception is an important driver of high fertility rates in West Africa. We do not find support for this hypothesis. Women who were given free access to...

We investigate the potential welfare cost of relative rank considerations using a series of vignettes and lab-in-the-field experiments with over 2,000 individuals in Abidjan, Ivory Coast. We show that: (1) individuals judged to be of a lower rank are perceived as more likely to be sidelined from...

Both under- and over-treatment of communicable diseases are public bads. But efforts to decrease one run the risk of increasing the other. Using rich experimental data on household treatment-seeking behavior in Kenya, we study the implications of this tradeoff for subsidizing life-saving...

Some education policymakers focus on bringing down pupil-teacher ratios. Others argue that resources will have limited impact without systematic reforms to education governance, teacher incentives, and pedagogy. We examine a program under which Kenyan Parent-Teacher Associations (PTAs) at...

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...

We study the demand for household water connections in urban Morocco, and the effect of such connections on household welfare. In the northern city of Tangiers, among homeowners without a private connection to the city's water grid, a random subset was offered a simplified procedure to purchase...

We study the dynamic relationship between women's intra-household reputation and investment decisions. We consider household investments delegated to the wife in settings where wives perceived to be savvy investors by their husbands are entrusted with a larger budget share. We show, first...

Is the persistently high fertility in West Africa today rooted in the decades of forced labor migration under colonial rule? We study the case of Burkina Faso, considered the largest labor reservoir in West Africa by the French colonial authorities. Hundreds of thousands of young men were...
