Do Natural Disasters Cause Domestic Violence?: A study of the 2015 Nepal earthquake (joint work with Arpita Khanna) [Paper]
Abstract
This study estimates the impact of exposure to the 2015 Nepal Earthquake on intimate partner violence with two rounds of Demographic and Health Surveys data. Using differences-in-differences estimation, we find that exposure to the earthquake lead to a statistically and economically significant increase in intimate partner violence in the urban areas but not in the rural areas. This is possibly due to an increase in the stress felt by the victims. We also offer some evidence that the impact heterogeneity between the urban and rural areas is attributable to the differences in the reconstruction processes and assistance provided.

Union Leaders: Experimental Evidence From Myanmar (joint work with Laura Boudreau, Rocco Macchiavello and Virginia Minni)
Abstract
Economic theory suggests that leaders may play a key roles in enabling social movements to overcome collective action problems through a variety of distinct mechanisms. Empirical tests of these theories outside the lab are scarce due to both measurement and identification challenges. We conduct multiple field experiments to test theories of leadership in the context of Myanmar’s burgeoning labor union movement. We collaborate with a confederation of labor unions as it mobilizes garment workers in the run-up to a national minimum wage negotiation. We present three sets of results. First, we document that union leaders differ from union members and non-members along several traits that economists identify as relevant for political selection and that psychologists have associated with ability to influence collective outcomes, respectively. Second, we randomly embed leaders in group discussions on workers’ preferred and expected minimum wage levels. A leader’s presence in the group improves group engagement and increases workers’ consensus around the unions’ preferred minimum wage levels. Third, we conduct a mobilization experiment in which workers are invited to participate in an< unannounced activity that features strategic complementarity in turnout. Leaders influence participation through both coordination and social pressure mechanisms rather than by simply motivating workers.

Uncertainty, Imperfect Information, and Expectation Formation over the Firm's Life Cycle

Abstract
Using a long-panel data set of Japanese firms that contains firm-level sales forecasts, we provide evidence on firm-level uncertainty and imperfect information over their life cycles. We find that firms make nonnegligible and positively correlated forecast errors. However, they make more precise forecasts and less correlated forecast errors when they become more experienced. We then build a model of heterogeneous firms with endogenous entry and exit where firms gradually learn about their demand by using a noisy signal. We present our novel approach to cleanly isolate the learning mechanism from other mechanisms by using expectations data over time. We combine the model with our data to perform a nonparametric decomposition of the age-declining forecast errors and find that learning accounts for between 20% to 40% of the overall decline in forecast errors observed in our data. Our model shows that, within the context of our cross-regional data, productivity gains from removing information frictions range from 6% to 12%.

Countervailing Power of Firms in International Trade [Paper]
Abstract
Price variation across buyers within product categories is commonly explained by quality variation in international trade. Using uniquely detailed product descriptions, I control for quality and study market-power mechanisms of price variation across buyers. I develop a model of trade, in which buyers and sellers differ in productivity and can have market power to set prices. It predicts differential patterns of price variation with buyer productivity under oligopoly, oligopsony and bilateral bargaining in a standard international trade environment.
Testing these predictions, I find that, in most markets, price variation is consistent with price discrimination by oligopolistic sellers charging lower mark-ups to more productive buyers. I identify the role of buyer’s outside options in this result separately from scale economies, transfer pricing and bargaining ability. These findings imply large productive firms benefit more
from trade liberalization due to their ability to further reduce input prices by threatening to use alternative suppliers.
