This paper examines a cost-reducing innovation to the delivery of "Self-Help Group" microfinance services. These groups typically rely on outside agents to found and administer the groups although funds are raised by the group members. The innovation is to have the agents earn their payment by...

This paper uses a difference-in-difference framework to estimate the effects of mobile money transfer technology (MMT) on healthcare usage in the face of negative health shocks. We use survey data from 2013-16 with quarterly observations on about 1,600 households of 10 villages in the Kisumu...

A growing literature relies on natural experiments to establish causal effects in macroeconomics. In diverse applications, natural experiments have been used to verify underlying assumptions of conventional models, quantify specific model parameters, and identify mechanisms that have major...

Assigning a third party at the 75th percentile of the centrality distribution (as compared to the 25th) increases efficiency by 21% relative to the mean: we attribute 2/5 of the effect to monitoring and 3/5 to enforcement. The largest efficiency increase occurs when senders and receivers are...

This study examines how the economic effects of elections in rural China depend on voter heterogeneity, for which we proxy with religious fractionalization. We first document religious composition and the introduction of village-level elections for a nearly nationally representative sample of...

This paper explores the relationship between openness to trade and to immigration on income per person. To address endogeneity concerns we extend the instrumental-variables strategy first used by Frankel and Romer (1999). We show that distance (geographical and cultural) can be used to build a...

In this paper, we begin by documenting substantial variation in house price growth across neighborhoods within a city during city wide housing price booms. We then present a model which links house price movements across neighborhoods within a city and the gentrification of those neighborhoods...

We document a statistical association between the severity of the persecution and mass murder of Jews (the Holocaust) by the Nazis during World War II and long-run economic and political outcomes within Russia. Cities that experienced the Holocaust most intensely have grown less, and cities as...

Recent contributions in the inequality literature have raised questions about previous research on skill-biased technical change and the managerial power of CEOs. Directly supporting our theme of prior exaggeration of the rise of inequality is new research showing that price indexes for the poor...

This paper uses confidential Census data, specifically the 1990 and 2000 Census Long Form data, to study the demographic processes underlying the gentrification of low-income urban neighborhoods during the 1990's. In contrast to previous studies, the analysis is conducted at the more refined...
