We propose a semiparametric measure to estimate systemic interconnectedness across financial institutions based on tail-driven spill-over effects in a ultra-high dimensional framework. Methodologically, we employ a variable selection technique in a time series setting in the context of a...

order to apply pricing tools of financial mathematics, one needs to isolate a Gaussian risk factor. A conventional model for … Gaussian variable appears. Earlier work investigated this temperature risk in dfferent locations and showed that neither … accurate fitting procedure of localised temperature risk process by achieving excellent normal risk factors. -- Weather …

In this paper we propose a new measure for systemic risk: the Financial Risk Meter (FRM). This measure is based on the … parameters over the 100 largest US publicly traded financial institutions. We demonstrate the suitability of this risk measure by … comparing the proposed FRM to other measures for systemic risk, such as VIX, SRISK and Google Trends. We find that mutual …

The Financial Risk Meter (FRM) is an established mechanism that, based on conditional Value at Risk (VaR) ideas, yields … insight into the dynamics of network risk. Originally, the FRM has been composed via Lasso based quantile regression, but we … coherent and multivariate tail risk indicator conditional expectile-based VaR (CoEVaR) can be derived, which is sensitive to …

It is an undisputed fact that weather risk increases over time due to climate change. However, qualification of this … statement with regard to the type of weather risk and geographical location is needed. We investigate the application of novel … statistical tools for assessing changes in weather risk over time. We apply local t-test, change point tests and Mann-Kendall test …
