Consumers lose access to credit when their congressional district boundaries are irregularly redrawn to benefit a political party (i.e., are gerrymandered). We identify this effect by matching a longitudinal panel of consumer credit data with changes in congressional district boundaries...

We document a new "policy sensitivity" channel of corporate political contributions. Firms that are highly sensitive to government policy uncertainty have a stronger incentive to contribute to political candidates, and these firms' risk-taking and performance should be more affected by the gain...

We exploit unexpected corporate data breaches to study how firms respond to negative reputation events. Data breaches negatively affect firm profitability, value, and reputation for years following the event, but are not triggered by high or low reputations. In response, firms increase their...

We document a robust dynamic inconsistency in risky choice. Using a unique brokerage dataset and two preregistered experiments, we compare people's initial risk-taking plans to their subsequent decisions. In both settings, people accept risk as part of a "loss-exit" strategy-planning to continue...

We present empirical evidence of the propagation of active investment strategies within a network of retail traders. Using a new, proprietary database drawn from a Facebook-style social network for individual investors, we verify the assumptions behind Han and Hirshleifer (wp, 2012). In their...

This research is the first to provide empirical evidence that social interaction is more prevalent amongst active rather than passive investors. While previous empirical work, spearheaded by Hong, Kubik, and Stein (2004), shows that proxies for sociability are related to participation in asset...

Many economically important settings, from financial markets to consumer choice, involve dynamic decisions under risk. People are willing to accept risk as part of a sequence of choices---even when it is fair or has a negative expected value---while at the same time rejecting positive-expected...
