In order to obtain the PhD degree, Nicolai Søgaard Laursen has submitted his thesis entitled:

Longevity risk in reinsurance and equity markets

This thesis centers on systematic longevity risk, which refers to the uncertainty of future survival rates for a group of individuals. The first chapter evaluates how an annuity provider can reduce the variability of a life annuity most efficiently by engaging in a mortality-linked security via two alternative hedging strategies, with and without basis risk. We find that eliminating basis risk is more cost-effective. The second chapter shows that an increase in unsystematic mortality raises one-year ahead real returns heterogeneously for portfolios sorted by industry and dividend-price ratios in the U.S stock market. In the third chapter, I show theoretically and empirically how longevity risk may help explain the value premium.
