open access: yesSSRN Electronic Journal, 2020
This paper studies the tail risk of US equity markets in advance of the COVID-19 outbreak in February 2020, providing evidence that financial markets are informative about pandemic risk well in advance of the actual outbreak. Specifically, while the tail risk of the market index did not respond before the outbreak, we document that the tail risk of ...

The Taxonomy of Tail Risk [PDF]

open access: yesSSRN Electronic Journal, 2023
AbstractWe use tail events at different levels of severity to define an asset's tail risk and to decompose the latter into a systematic and an idiosyncratic component. The systematic component captures an asset's tendency to experience joint tail losses with the market and generalizes a classic tail dependence coefficient.

Measuring tail risks

open access: yesThe Journal of Finance and Data Science, 2022
Value at risk (VaR) and expected shortfall (ES) are common high quantile-based risk measures adopted in financial regulations and risk management. In this paper, we propose a tail risk measure based on the most probable maximum size of risk events (MPMR) that can occur over a length of time.

Sovereign Tail Risk [PDF]

open access: yesSSRN Electronic Journal, 2014
We provide a new measure of sovereign country risk exposure (SCRE) to global sovereign tail risk based on information incorporated in 5-year sovereign CDS spreads. Our panel regressions with quarterly data from 53 countries show that macro risks have strong explanatory power for SCRE.

Tail risk interdependence [PDF]

open access: yesInternational Journal of Finance & Economics, 2019
AbstractWe present a framework focused on the interdependence of high‐dimensional tail events. This framework allows us to analyse and quantify tail interdependence at different levels of extremity, decompose it into systemic and residual part and to measure the contribution of a constituent to the interdependence of a system.

On the Measurement of Economic Tail Risk [PDF]

open access: yesOperations Research, 2014
This paper attempts to provide a decision-theoretic foundation for the measurement of economic tail risk, which is not only closely related to utility theory but also relevant to statistical model uncertainty. The main result is that the only risk measures that satisfy a set of economic axioms for the Choquet expected utility and the statistical ...

Tail risk of contagious diseases [PDF]

open access: yesNature Physics, 2020
Applying a modification of Extreme value Theory (thanks to a dual distribution technique by the authors on data over the past 2,500 years, we show that pandemics are extremely fat-tailed in terms of fatalities, with a marked potentially existential risk for humanity.
