This paper derives indicators of the severity and structure of banking system risk from asymptotic interdependencies between banks’ equity prices. We use new tools available from multivariate extreme value theory to estimate individual banks’ exposure to each other (“contagion risk”) and...

We study the dependence between the downside risk of European banks and insurers. Since the downside risk of banks and insurers differs, an interesting question from a supervisory point of view is the risk reduction that derives from diversification within large banks and financial...

Accounting fraud and many other forms of fraud and corruption are occurring around the globe. Alternative strategies that are based on sound research-based findings from different situations are needed if there is to be a systematic reduction in the occurrence of these forms of fraud. This...

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 tail of financial returns is typically governed by a power law (i.e. “fat tails”). However, the constancy of the so-called tail index α which dictates the tail decay has been hardly investigated. We study the finite sample properties of some recently proposed endogenous tests for...

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 contribution of this paper is the extension of theoretical and practical applicability in complex systems of a fundamental concept of extreme value theory. More precisely, the paper formulates a stochastic model and establishes the sufficient conditions for evaluating its distribution...

In the era of digitalization, cryptocurrencies have become an alternative asset for both retail and institutional investors. While the new emerging digital ecosystem based on blockchain technology has been praised for offering plenty of advantages such as decentralization, discretion or...

Adoption of Artificial Intelligence (AI) is slowly but steadily becoming all pervasive, spanning products and services in all domains. The level of intelligence that is being utilized is also rapidly increasing over different dimensions. Image processing, Natural Language Processing, Analytics...
