We examine the impact of offering conditional cash transfer (CCT) beneficiaries the choice to receive cash transfers in bank accounts instead of cash. We investigate the effects on savings behavior and downstream outcomes such as assets and trust. We find, on average, no significant impact on...

This paper models economic development as a process of institutional transformation by focusing on the interplay between agents' occupational decisions and the distribution of wealth. Because of capital market imperfections, poor agents choose working for a wage over self-employment, and wealthy...

Most modern supervised statistical/machine learning (ML) methods are explicitly designed to solve prediction problems very well. Achieving this goal does not imply that these methods automatically deliver good estimators of causal parameters. Examples of such parameters include individual...

We revisit the classic semiparametric problem of inference on a low di-mensional parameter Ø0 in the presence of high-dimensional nuisance parameters Û0. We depart from the classical setting by allowing for Û0 to be so high-dimensional that the traditional assumptions, such as Donsker...

We propose strategies to estimate and make inference on key features of heterogeneous effects in randomized experiments. These key features include best linear predictors of the effects using machine learning proxies, average effects sorted by impact groups, and average characteristics of most...

The construction of large dams is one of the most costly and controversial forms of public infrastructure investment in developing countries, but little is known about their impact. This paper studies the productivity and distributional effects of large dams in India. To account for endogenous...

In Côte d'Ivoire, as in much of Africa, husbands and wives farm different crops on separate plots. These different crops are differentially sensitive to particular kinds of rainfall shocks. We find that conditional on overall household expenditure, the composition of expenditure is sensitive to...
