In this note we demonstrate that in affine models for bilateral exchange rates, the nature of return interdependence during crises depends on the tail properties of the fundamentals' distributions. We denote crisis linkages as either strong or weak, in the sense that the dependence remains or...

We study co-movement of 10-year sovereign bond yields of 11 EU countries. Our analysis is focused mainly on changes of co-movement in the crisis period, especially near two significant dates - the fall of Lehman Brothers, September 15, 2008, and the announcement of increase of Greek's public...

We characterize asset return linkages during periods of stress by an extremal dependence measure. Contrary to correlation analysis, this nonparametric measure is not predisposed toward the normal distribution and can allow for nonlinear relationships. Our estimates for the G-5 countries suggest...

The paper offers an alternative approach to analyzing stock market time series data. The purpose is to develop descriptive, more intuitive, and closer to reality analogs of the behavior of US stock market prices, as indexed by the S&P500 stock price index covering the period October 2003 to...

This paper proposes and evaluates several market-based measures for US and eurozone individual bank tail risk and banking system risk. We apply statistical extreme value analysis to the tails of bank equity prices to estimate the likelihood of individual institutions financial distress as well...

The stochastic mathematical model of the credit risk process is examined. It is assumed that in unstable economic condition of default may be a cause for credit risk. The fund value of the crediting is considered as some random variable that is changed step-wise at instants of the payments of a...

The empirical performance of the Q theory of investment can be significantly improved by simultaneously considering the time- and the frequency-varying features of the investment-Q relationship. Using continuous wavelet tools, I assess the investment-Q sensitivity at different frequencies and...

This paper tests the hypothesis that stress tests are primarily a function of the fundamental financial condition and operating environment of individual banks, rather than alternative adverse economic and financial scenarios imposed by regulators. We develop a novel early warning system based...

In this paper, we show that the comovement of bond yields in the EU before and during the European sovereign debt crisis is frequency-dependent. Using frequency cohesion and wavelet coherence, we demonstrate that the comovement is concentrated mainly at low frequencies. The comovement decreased...

This paper develops a novel measure of systemic risk that combines mapping technology and regression methods. Self-organizing maps (SOM) and lasso logistic regressions are employed to estimate default probabilities for individual U.S. commercial banks from 2001 to 2017. Subsequently, these...
