Forbes and Rigobon (2002) claim there was no contagion among international stock markets duringthe 1997 Asian crisis, with contagion being defined as an increase in dependence. We revisit thisissue using a more robust methodology based on copula. After controlling for heteroskedasticitywith the...

It is well-known in empirical finance that virtually all asset returns, whether monthly,daily, or intraday, are heavy-tailed and, particularly for stock returns, are mildly but oftensignificantly negatively skewed. However, the tail indices, or maximally existing moments ofthe returns, can...

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. …

In this paper we present a model to price and hedge basket credit derivatives andcollateralised loan obligation. Based upon the copula-approach by Schönbucher and Schubert (2001) the model allows a specification of the joint dynamics of credit spreads and default intensities, including a...

In this paper we provide a convenient econometric framework for the analy-sis of nonlinear dependence in financial applications. We introduce models withconstrained nonparametric dependence, which specify the conditional distrib-ution or the copula in terms of a one-dimensional functional...
