We study the long-run effects of a big-push “graduation” program in Ethiopia in which very poor households received a one-time transfer of productive assets (mainly livestock), technical training, and access to savings accounts. After seven years, treatment effects on wealth and consumption...

Sustainable intensification is predicated on climate-smart agricultural input adoption. We test strategies for promoting the adoption of climate-smart agricultural inputs in Nigeria with a private sector firm. We disentangle the effects of price discount promotions (25 percent discounts)...

What accounts for the ubiquity of small vendors operating side-by-side in the urban centers of developing countries? Why don’t competitive forces drive some vendors out of the market? We ran an experiment in Kolkata vegetable markets in which we induced (via subsidizing) some vendors to sell...

Online platforms often face challenges being both fair (i.e., non-discriminatory) and efficient (i.e., maximizing revenue). Using computer vision algorithms and observational data from a microlending marketplace, we find that choices made by borrowers creating online profiles impact both of...

The CES aggregator and its demand system are ubiquitous in business cycles theory, macroeconomic growth and development, international trade and other general equilibrium fields, because it has many knife-edge properties, which help to keep the analysis tractable in the presence of many goods...

Classic theories suggest that common pool resources are subject to overexploitation. Community-based resource management approaches may ameliorate “tragedy of the commons” effects. Using a randomized evaluation in Namibia’s communal rangelands, we find that a comprehensive four-year...

A central challenge to telephone surveys is low response rates. This is particularly true for random digit dial (RDD) surveys, which have especially low response rates. For researchers designing RDD survey protocols, there is a clear tradeoff between effort and composition, where surveys can...
