Faced with the problem of pricing complex contingent claims, investors seek to make their valuations robust to model uncertainty. We construct a notion of a modeluncertainty-induced utility function and show that model uncertainty increases investors' effective risk aversion. Using this utility...

We develop an incomplete markets framework to synthesize domestic and foreign stochastic discount factors (SDFs) that are consistent with limited international risk sharing. The fundamental departure in our paper is that exchange rate growth need not equal the ratio of SDFs, and we develop a...

The VIX futures curve is most often in contango but displays backwardation during unfavorable market conditions. We construct an explanation based on the notion of stochastic orders of volatility uncertainty – meaning that investors view short-dated volatility uncertainty as being less likely...

We develop a way of ranking and scoring actively managed funds and investment strategies. Our performance measure accounts for the feature that investors may exhibit caution, via the mechanism of ambiguity aversion, when evaluating investment strategies. Linking developed theory to data, we...
