This paper investigates an empirical puzzle in technology adoption for developing countries: the low adoption rates of technologies like hybrid maize that increase average farm profits dramatically. I offer a simple explanation for this: benefits and costs of technologies are heterogeneous, so that farmers with low net returns do not adopt the technology. I examine this hypothesis by estimating a correlated random coefficient model of yields and the corresponding distribution of returns to hybrid maize. This distribution indicates that the group of farmers with the highest estimated gross returns does not use hybrid, but their returns are correlated with high costs of acquiring the technology (due to poor infrastructure). Another group of farmers has lower returns and adopts, while the marginal farmers have zero returns and switch in and out of use over the sample period. Overall, adoption decisions appear to be rational and well explained by (observed and unobserved) variation in heterogeneous net benefits to the technology.

Voter mobilization campaigns face trade-offs in young democracies. In a large-scale experiment implemented in 2013 with the Kenyan Electoral Commission (IEBC), text messages intended to mobilize voters boosted participation but also decreased trust in electoral institutions after the election, a decrease that was stronger in areas that experienced election-related violence, and for individuals on the losing side of the election. The mobilization backfired because the IEBC promised an electronic voting system that failed, resulting in manual voting and tallying delays. Using a simple model, we show signaling high institutional capacity via a mobilization campaign can negatively affect beliefs about the fairness of the election.

Should developing countries give everyone enough money to live on? Interest in this idea has grown enormously in recent years, reflecting both positive results from a number of existing cash transfer programs and also dissatisfaction with the perceived limitations of piecemeal, targeted approaches to reducing extreme poverty. We discuss what we know (and what we do not) about three questions: what recipients would likely do with the incremental income, whether this would unlock further economic growth, and the potential consequences of giving the money to everyone (as opposed to targeting it).

We examine the potential of asset-collateralized loans in low-income country credit markets. When a Kenyan dairy cooperative exogenously replaced high down payments and joint liability requirements with loans collateralized by the asset itself - a large water tank- loan take-up increased from 2.4% to 41.9%. In contrast, substituting joint liability requirements for deposit requirements had no impact on loan take up. There were no repossessions among farmers allowed to collateralize 75% of their loans, and a 0.7% repossession rate among those offered 96% asset collateralization. A Karlan-Zinman test based on waiving borrowing requirements ex post finds evidence of adverse selection with very low deposit requirements, but not of moral hazard. A simple model and rough calibration suggests that adverse selection and regulatory caps on interest rates may deter lenders from making welfare-improving loans with low deposit requirements. We estimate that 2/3 of marginal loans led to increased water storage investment. Real effects of loosening borrowing requirements include increased household water access, reductions in child time spent on water-related tasks, and greater school enrollment for girls.

A growing body of rigorous research shows that financial services innovations can have important positive impacts on wellbeing, but also that many do not. We first describe the latest evidence on what works in financial inclusion. Second, we summarize research on key financial market failures and on products and innovations that address specific mechanisms underlying them. We conclude by highlighting open areas for future work.
