We study a bank run in India in which private bank branches experience sudden and considerable loss of deposits that seek safety in state-owned public sector banks (PSBs). We trace the consequences of this reallocation using granular data on bank-firm relationships and branch balance sheets. The...

We examine the desirability of granting "safe harbor" provisions to creditors of financial intermediaries in sale-and-repurchase (repo) contracts. Exemption from an automatic stay in bankruptcy enables financial intermediaries to raise greater liquidity and induces entry of intermediaries with...

We show that supply networks are inefficiently, and insufficiently, resilient. Upstream firms can expand their production capacity to hedge against supply and demand shocks. But the social benefits of such investments are not internalized due to market power and market incompleteness. Upstream...

Network diffusion models are used to study things like disease transmission, information spread, and technology adoption. However, small amounts of mismeasurement are extremely likely in the networks constructed to operationalize these models. We show that estimates of diffusions are highly...

We examine friendships and study partnerships among university students over several years. At the aggregate level, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences, and different network layers. At the individual...

To understand new information, we exchange models or interpretations with others. This paper provides a framework for thinking about such social exchanges of models. The key assumption is that people adopt the interpretation in their network that best explains the data, given their prior...

Adaptation to dynamic conditions requires a certain degree of diversity. If all agents take the best current action, learning that the underlying state has changed and behavior should adapt will be slower. Diversity is harder to maintain when there is fast communication between agents, because...

In an RCT with US small businesses, we document that a large share of firms are not well-informed about bankruptcy. Many assume that bankruptcy necessarily entails the death of a business and do not know about Chapter 11 bankruptcy, where debts are renegotiated so that the business can continue...

We examine banking regulation in a macroeconomic model of bank runs. We construct a general equilibrium model where banks may default because of fundamental or self-fulfilling runs. With only fundamental defaults, we show that the competitive equilibrium is constrained efficient. However, when...

Secured debt--a debt contract that offers security to creditors in the form of collateralized assets--has been a cornerstone of credit markets in most societies since antiquity. The ability to seize and sell collateral reduces the creditor's expected losses when the debtor defaults on a promised...
