We consider dynamic sublinear expectations (i.e., time-consistent coherent risk measures) whose scenario sets consist … of singular measures corresponding to a general form of volatility uncertainty. We derive a càdlàg nonlinear martingale …

We use cross-country microdata to analyse the risk taking of households in Europe and the US. Concerning the extensive … inside Europe we document substantial differences. Furthermore, average risk aversion is strongly correlated with the share … explainable by household characteristics as well as differences in risk aversion and a remainder.

We test these strategies on a universe of 64 …

While it is established that idiosyncratic volatility has a negative impact on the cross-section of future stock … returns, the relationship between idiosyncratic volatility and future hedge fund returns is largely unexplored. We document … that hedge funds with high idiosyncratic volatility outperform and this pattern is explained by the positive return effect …

This paper analyzes optimal hedging of a tradable risk (e.g. price risk or exchange rate risk) with forward contracts … in the presence of untradable inflation risk. Utility is defined over real wealth. Optimal forward positions are derived … relative to a given initial exposure in the tradable risk. A nominally unbiased forward market usually implies a non-zero real …
