This paper studies the effect of variance swap in hedging volatility risk under the mean-variance criterion. We … variance swap can be used to hedge against the volatility risk. In the second problem, only the bank account and the stock can … be traded in the market, which is incomplete since the idiosyncratic volatility risk is unhedgeable. Under an exponential …

model with stochastic disaster risk. That is, we show that a model with a stochastic probability of disaster can explain … stochastic disaster risk model to one that allows for variation in the risk of disaster at different time scales. We show that …

sectors with respect to shock propagation risk can lead to highly persistent aggregate price-dividend ratios. Finally, the … possibility of jumps in one sector triggering higher overall jump probabilities boosts jump risk premia while uncertainty about … the regime is the reason for sizeable diffusive risk premia. …
