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...

Jenny Aker and Isaac Mbiti 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. They first provide an overview of the patterns and determinants of mobile...

Many agricultural and environmental technologies require large upfront investments in exchange for longer-term benefits. This time profile of costs and benefits makes adoption particularly sensitive to liquidity and credit constraints, which are prevalent in low-income settings. We test the...

Despite recent calls in support of cash transfers, there is little rigorous evidence of the relative impacts of cash versus in-kind transfers, especially in humanitarian contexts, where a majority of such programs take place. This paper uses data from a randomized experiment in the Democratic...
