The informativeness of risk factor disclosures is a subject of debate. We predict and find that risk factor disclosures in 10-K filings reduce the chance of a large negative movement in stock prices—stock price crash risk. This effect is further identified through a difference-in-differences...

We test the hypothesis that practicing Enterprise Risk Management (ERM) reduces firms' cost of reducing risk. Adoption of ERM represents a radical paradigm shift from the traditional method of managing risks individually to managing risks collectively allowing ERM-adopting firms to better...

In this paper, we investigate the asymptotic behavior of the portfolio diversification ratio based on Value-at-Risk (quantile) under dependence uncertainty, which we refer to as "worst-case diversification limit." We show that the worst-case diversification limit is equal to the upper limit of...

Research related to aggregation, robustness, and model uncertainty of regulatory risk measures, for instance, Value-at-Risk (VaR) and Expected Shortfall (ES), is of fundamental importance within quantitative risk management. In risk aggregation, marginal risks and their dependence structure are...
