How do markets respond to extreme rainfall in West Africa? This paper examines the effect of weather on grain market performance in Niger, a country increasingly affected by drought and severe food crises over the past two decades. Using a dataset that combines information on rainfall,...

Conditional and unconditional cash transfers often help improve development outcomes, yet their costs to program recipients and implementing agencies are rarely discussed. Mobile money transfer systems in many developing countries now offer more cost-effective implementation of cash transfer...

We examine the growth of mobile phone technology over the past decade and consider its potential impacts upon quality of life in low-income countries, with a particular focus on sub-Saharan Africa. We first provide an overview of the patterns and determinants of mobile phone coverage in...

Cell phones are quickly transforming markets in low-income countries. The effect is particularly dramatic in rural areas of sub-Saharan Africa, where cell phones often represent the first telecommunications infrastructure. Niger had approximately 2 landlines for every 1,000 people when mobile...

Despite the increased use of conditional and unconditional cash-transfer programs worldwide, a majority of social protection programs in both developed and developing countries use in-kind transfers and vouchers. This paper reports the results of a randomized evaluation of an unconditional cash...

The recent wave of randomized trials in development economics has provoked criticisms regarding external validity. We investigate two concerns—heterogeneity across beneficiaries and implementers—in a randomized trial of contract teachers in Kenyan schools. The intervention, previously shown...

Rice production in Africa has tended to be low-yielding, geographically dispersed, and uncompetitive against low-cost Asian imports, even when protected by high freight costs and substantial trade barriers. Skyrocketing prices in world markets in 2007-08 were a chock to African consumers,...

Agriculture can serve as an important engine for economic growth in developing countries, yet yields in these countries have lagged far behind those in developed countries for decades. One potential mechanism for increasing yields is the use of improved agricultural technologies, such as...

This paper addresses two important economic issues for Africa: the contribution of national borders and ethnicity to market segmentation and integration between and within countries. Market pair regression analysis provides evidence of higher conditional price dispersion for both a grain and a...

CGD non-resident fellow Jenny Aker and co-authors report on the results from a randomized evaluation of a mobile phone education program (Project ABC) in Niger, in which adult students learned how to use mobile phones as part of a literacy and numeracy class. Overall, students demonstrated...
