In March 2013, Lululemon Athletica removed its inventory of women's black yoga pants from its stores because recent shipments of the product were “too sheer.” For a company reliant on a reputation for quality, the news was devastating. Worse, the recall set off a series of PR related...

In this paper, I develop a model in which risk-averse investors possess private information regarding both a stock's expected payoff and its risk. These investors trade in the stock and a derivative whose payoff is driven by the stock's risk. In equilibrium, the derivative is used to speculate...

We develop a measure of how information events impact investors' perceptions of risk that is broadly applicable and simple to implement. We derive this measure from an option-pricing model where investors anticipate an announcement that simultaneously conveys information on the announcer's...

The standard solution concept for stochastic games is Markov perfect equilibrium (MPE); however, its computation becomes intractable as the number of players increases. Instead, we consider mean field equilibrium (MFE) that has been popularized in the recent literature. MFE takes advantage of...

We build a linear-quadratic model to analyze trading in a market with private information and heterogeneous agents. Agents receive private taste/inventory shocks and trade continuously. Agents differ in their need for trade as well as the cost to hold excessive inventory. In equilibrium, trade...

Hiring occurs primarily to fill vacant slots that occur when workers separate. Equivalently, separation occurs to move workers to better alternatives. A model of efficient separations yields several specific predictions. Labor market churn is most likely when mean wages are low and the variance...

Most investors have a single goal: to earn the highest financial return. These socially-neutral investors maximize their risk-adjusted returns and would not accept a lower financial return from an investment that also produced social benefits. An increasing number of socially-motivated investors...

Active fund managers are skilled and, on average, have used their skill to generate about $3.2 million per year. Large cross-sectional differences in skill persist for as long as ten years. Investors recognize this skill and reward it by investing more capital in funds managed by better...

We use a dataset of sell-side analysts' scenario-based equity valuation estimates to examine whether analysts can assess the state-contingent risk surrounding a firm's fundamental value. We find that the spread in analysts' scenario-based valuations captures the riskiness of operations and...
