My PhD thesis consists of three papers which study the nature, structure, dynamics and price of variance risks. As tool I make use of multivariate affine jump-diffusion models with matrix-valued state spaces. The first chapter proposes a new three-factor model for index option pricing. A core...

Risk-averse expected utility maximization implies that the pricing kernel must be a non-increasing function of aggregate wealth. However, empirical research has found that the pricing kernel frequently displays a locally increasing portion in aggregate wealth. This is known as the pricing kernel...

Coastal flooding, exacerbated by sea level rise, is a considerable economic threat to low-lying regions. I investigate whether investors account and insure for this hazard by exploiting the heterogeneity of country exposure to current and future coastal floods. Using sovereign credit default...
