Using textual analysis and comparing cybersecurity-risk disclosures of firms that were hacked to others that were not …, we propose a novel firm-level measure of cybersecurity risk for all US-listed firms. We then examine whether … cybersecurity risk is priced in the cross-section of stock returns. Portfolios of firms with high exposure to cybersecurity risk …

We introduce and study the main properties of a class of convex risk measures that refine Expected Shortfall by … adjusted Expected Shortfalls quantify risk as the minimum amount of capital that has to be raised and injected into a financial … probability level p\in[0,1].

The forward-looking nature of option market data allows one to derive economically-based and model-free risk measures … classical risk measures for the S&P500 Index. Delivering good results both at short and long time horizons, the proposed option …-implied risk metrics emerge as a convenient alternative to the existing risk measures …

We introduce a class of quantile-based risk measures that generalize Value at Risk (VaR) and, likewise Expected … probability of occurrence. The corresponding risk measure, called Loss VaR (LVaR), determines the minimal capital injection that … and applications to capital adequacy, portfolio risk management and catastrophic risk are presented …

I develop a dynamic capital structure model to examine how the nature of risk affects firm's debt policy. In the model …, firm's fundamental risk, captured by its cash flow process, consists of transitory and persistent parts with markedly … different dynamics. The model explains the observed dispersion in the risk-leverage relationship. Firms with similar total …

We address the problem of risk sharing among agents using a two-parameter class of quantile-based risk measures, the so …-called Range-Value-at-Risk (RVaR), as their preferences. The family of RVaR includes the Value-at-Risk (VaR) and the Expected … Shortfall (ES), the two popular and competing regulatory risk measures, as special cases. We first establish an inequality for …
