We examine how professional traders behave in two financial market experiments; we contrast professional traders' behavior to that of undergraduate students, the typical experimental subject pool. In our first experiment, both sets of participants trade an asset over multiple periods after...

We run an experiment where professional traders, endowed with private information, trade an asset over multiple periods. After the trading game, we gather information about the professional traders' characteristics by having them carry out a series of tasks. We study which of these...

This paper develops a model to study the formation and regulation of information transmission networks. We analyze a cat and mouse game between a regulator, who sets and enforces a regulatory environment, and agents, who form networks to disseminate and share insider information. For any given...

We study the effect of market structure on a personal computer manufacturer’s decision to adopt new technology. This industry is unusual because there exist two horizontally segmented retail markets with different degrees of competition: the IBM-compatible (or PC) platform and the Apple...

This paper is intended to serve as a reference guide on U.S. repo and securities lending markets. It begins by presenting the institutional structure, and then describes the market landscape, the role of the participants, and other characteristics, including how repo and securities lending...

This paper develops a technique to decompose price distributions into contributions from markups and marginal cost. The estimators are then used as a laboratory to measure the relationship between increasing Chinese competition and the components of U.S. import prices. The estimates suggest that...

We develop a model of misinformation wherein users' decisions to verify and share news of unknown truthfulness interact with producers' choices to generate fake content as two sides of a market that balance to deliver an equilibrium prevalence and pass-through of fake news. We leverage the...

We propose measures of financial market stress for forty-six countries and regions across the world. Our measures indicate that worldwide financial market stresses rose significantly in March following the widespread economic shutdowns in the wake of the COVID-19 pandemic. However, hardly...

In a financial system in which balance sheets are continuously marked to market, asset price changes appear immediately as changes in net worth, eliciting responses from financial intermediaries who adjust the size of their balance sheets. We document evidence that marked-to-market leverage is...

We study a contracting model of leverage and balance sheet size for financial intermediaries that fund their activities through collateralized borrowing. Leverage and balance sheet size increase together when measured risks decrease. When the loss distribution is exponential, the behavior of...
