We propose a bootstrap-based robust high-confidence level upper bound (Robust H-CLUB) for assessing the risks of large portfolios. The proposed approach exploits rank-based and quantile-based estimators, and can be viewed as a robust extension of the H-CLUB method (Fan et al., 2015). Such an...

We describe characteristics of various risk measures (Value-at-Risk, Expected Shortfall, etc.) that are used to analyze and quantify the tail risk exposure, and discuss their relative strengths and weaknesses. Emphasis is placed on presenting and comparing methodologies to compute and backtest...

Robustness of risk measures to changes in underlying loss distributions (distributional uncertainty) is of crucial importance when making well-informed risk management decisions. In this paper, we quantify for any given distortion risk measure its robustness to distributional uncertainty by...

This paper documents that changes in litigation risk affect corporate voluntary disclosure practices. We make causal inferences by exploiting three legal events that generate exogenous variations in firms' litigation risk. Using a matching-based, fixed-effect difference-indifferences design, we...

Using a large set of restatement announcements and regulatory filings by U.S.-listed firms between 2003 and 2009, we find evidence that managers aim to reduce litigation risk by (1) bundling negative information, such as earnings restatements, with other public announcements, and (2) leaking...

In broad samples, insider selling does not increase the likelihood of a class-action lawsuit filing. In this paper, we examine the reasons behind this finding. We find that insider sales significantly increase lawsuit probability only when we jointly consider insider identity, insider sale...

In 2001, Nevada significantly limited the personal legal liability of corporate officers and directors. We use this exogenous shock to implement a differences-in-differences design that examines the impact of officer and director litigation risk on agency costs. We find decreased firm value,...

Does personal litigation risk for independent directors materially affect firm valuation, compensation-related issues for independent directors, and board composition decisions? We use the unexpected In re Investors Bancorp decision in 2017 by the Delaware Supreme Court, which lowered the...

After decades of declining litigation risk, independent directors of public companies are viewed as effectively immune to personal litigation costs. However, the unexpected In re Investors Bancorp decision by the Delaware Supreme Court in 2017 lowered the liability threshold only for directors...
