This paper uses copulas to model the joint survival within the groups of hedge funds and funds of funds managed by the same manager. Given their skewed distribution, a simple survival analysis based on linearity assumptions may fail to fully capture the dependence caused by extreme events in the...

We consider a dependent competing risks model with many risks and many covariates. We show identifiability of the marginal distributions of latent variables for a given dependence structure. Instead of directly estimating these distributions, we suggest a plug-in regression framework for the...

We introduce a new discounted cash flow model which integrates the diversification effect of multi-business firms. We face two challenges. One is examining how different degrees of diversification can affect firm value due to risk reduction, and the other is modeling segment-specific cash flows...

The correlation bias refers to the fact that claim subordination in the capital structure of the firm influences claim holders’ preferred degree of asset correlation in portfolios held by the firm. Using the copula capital structure model, it is shown that the correlation bias shifts...

In this article, we provide an alternative evidence of asymmetric information in automobile insurance based on a copula model. We use the Frank’s copula to jointly model the type of policy coverage chosen and the number of accidents, with the dependence parameter providing for evidence of the...

Purpose – The purpose of this paper is to study the correlation structure of the credit spreads. Design/methodology/approach – The minimal spanning tree is used to find the risk center node and the basic correlation structure of the credit spreads. The dynamic copula and pair copula models...

Nowadays, the interaction and dependence among various components in the capital markets, both locally and internationally, have become stronger than before, mainly on account of greater integration of financial markets, financial innovations, technology innovation which facilitate in massive...
