This paper examines a well known empirical puzzle in the literature on technology adoption: despite the potential of technologies to increase returns dramatically, a significant fraction of households do not use these technologies. I study the use of hybrid maize and fertilizer in Kenya, where...

The investment decisions of small-scale farmers in developing countries are conditioned by their financial environment. Binding credit market constraints and incomplete insurance can reduce investment in activities with high expected profits. We conducted several experiments in northern Ghana in...

We partnered with a micro-lender in Mali to randomize credit offers at the village level. Then, in no-loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with...

We use newly-available Indian panel data to estimate how the returns to planting-stage investments vary by rainfall realizations. We show that the forecasts significantly affect farmer investment decisions and that these responses account for a substantial fraction of the inter-annual...

This paper investigates the impacts of cotton marketing reforms on farm productivity, a key element for poverty alleviation, in rural Zambia. The reforms comprised the elimination of the Zambian cotton marketing board that was in place since 1977. Following liberalization, the sector adopted an...

The paper analyzes 141 villages in Matlab, Bangladesh from 1974 to 1996, in which half the villages received from 1977 to 1996 a door-to-door outreach family planning and maternalchild health program. Village and individual data confirm a decline in fertility of about 15 percent in the program...

In this paper, we use new survey data on twins born in urban China, among whom many experienced the consequences of the forced mass rustication movement of the Chinesecultural revolution,ʺ to identify the distinct roles of altruism and guilt in affecting behavior within families. Based on a...

The program evaluation literature for population and health policies is in flux, with many disciplines documenting biological and behavioral linkages from fetal development to late life mortality, chronic disease, and disability, though their implications for policy remain uncertain. Both macro...

We test how donors respond to new information about a charity's effectiveness. Freedom from Hunger implemented a test of its direct marketing solicitations, varying letters by whether they include a discussion of their program's impact as measured by scientific research. The base script, used...

Should agricultural development programs target women in order to increase productivity? This paper reviews the extensive literature on men's and women's relative productivity in agriculture, most of which concludes that controlling for access to inputs, plot and farmer characateristics, there...
