This paper presents an intellectual exchange with ChatGPT, an artificial intelligence chatbot, about correlation pitfalls in risk management. The exchange takes place in the form of a conversation that provides ChatGPT with context. The purpose of this conversation is to evaluate ChatGPT's...

CDO tranche spreads (and prices of related portfolio-credit derivatives) depend on the market's perception of the future loss distribution of the underlying credit portfolio. Applying Sklar's seminal decomposition to the distribution of the vector of default times, the portfolio-loss...

This paper presents an intellectual exchange with ChatGPT, an artificial intelligence chatbot, about correlation pitfalls in risk management. The purpose of this discussion is to evaluate ChatGPT’s understanding of these pitfalls and to offer readers an engaging alternative for learning about...

Both at the design stage as well as at the pricing stage of Alternative Risk Transfer (ART) products, the notion of low (zero) beta plays an important role. By now it is well known that for these non--standard products, the interpretation of dependence through linear correlation (and hence the...

In this paper we test for structural changes in the conditional dependence of two-dimensional foreign exchange data. We show that by modeling the conditional dependence structure using copulae we can detect changes in the dependence beyond linear correlation like changes in the tail of the joint...
