We develop models for portfolio diversification in the sovereign credit default swap (CDS) markets and show that, despite literature findings that sovereign CDS spreads are affected by global factors, there is sufficient idiosyncratic risk to be diversified away. However, we identify regime...

This paper explores how the medical expenditure risk affects the households' portfolio choice across health status theoretically in a life cycle model and empirically using machine learning methods. Medical expenditure risk, as a background risk, can relocate households' financial decisions. A...

This paper provides a model which helps explain the variability of stock liquidity premium. I model liquidity as a time-varying price impact and include both permanent as well as temporary price impact. Liquidity premium is defined as an additional return that stock should yield to compensate an...

I study the history and performance of commercial real estate (CRE) in the pension fund portfolio, showing how many plan sponsors fundamentally changed their approach to CRE investment once underfunding gaps began to emerge in the early and middle 2000s. Several new empirical facts are...

We develop a model in which investment risk drives the demand for CDS insurance. The model shows the efficiency of CDS contracting over the state of the economy. It shows that CDS overinsurance (insurance in excess of renegotiation surpluses) is procyclical, allowing for greater financing when...

We propose the use of partial myopia as an alternative approach to dynamic programming for solving a multi-period investment problem with background risks. An investor behaves partially myopically if the investor makes his decision as if his total wealth at the end of the next period will be...

A drawback of available portfolio credit risk models is that they fail to allow for default risk dependency across loans other than through common risk factors. Thereby, thesemodels ignore that close ties can exist between companies due to legal, financial and business relations. In this paper,...

Climate change poses an existential threat. The authors argue that carbon pricing and green research and development (R&D) support are good economics, but their implementation can be improved. Even if carbon prices are generalized and given more substance, green R&D is still likely to be smaller...

Why are there so few women in finance and even less managing funds? There is a major discrepancy between the number of female and male fund managers worldwide. The aim of this paper is to ascertain if gender is a contributing factor for fund managers performance. This is examined through...
