In this paper we discuss some statistical pitfalls that may occur in modeling cross-dependences with copulas in financial applications. In particular we focus on issues arising in the estimation and the empirical choice of copulas as well as in the design of time-dependent copulas.

We examine the quantification of operational risk for banks. We adopt a financial-economics approach and interpret … operational risk management as a means of optimizing the profitability of an institution along its value chain. We start by defining … operational risk and then propose a framework to model risk mitigation through the bank’s value chain over time. Using analytical …

We cionsider semiparmetric assymetric kernel density estimators when the unkonwn density has support on [0,∞). We provide a unifying framework which contains assymmetric kernel versions of several semiparametric density estimators considered previously in the literature. This framework allows...
