In village economies, insurance networks are key to smoothing shocks, while production networks can propagate them. The interplay of these networks is crucial. We show that a significant health expenditure shock to one household propagates to other linked households via supply-chain and labor...

We measure heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and complement the results with a measure based on optimal portfolio choice. Among households with relatives living in the same village, full insurance cannot be rejected, suggesting that...

Some gasoline markets exhibit remarkable price cycles, where price spikes are followed by a string of small price declines until the next price spike. This pattern is predicted from a model of competition driven by Edgeworth cycles, as described by Maskin and Tirole. We extend the Maskin and...

Families run a large fraction of business groups around the world. In this paper, we analyze how the structure of the families behind these business groups affects the groups' organization, governance and performance. To address this question, we constructed a unique data set of family trees and...

There are surprisingly few estimates of the effect of sales taxes on retail prices, especially at the firm level. Further, along both sides of a state border, a change in one state's sales tax can shed light on the nature of competition, as a subset of firms effectively experiences a change in...

This paper provides a theory-based empirical framework for understanding the risk and return on productive capital assets and their allocation across activities in an economy characterized by idiosyncratic and aggregate risk and thin formal markets for real and financial assets. We apply our...
