This paper studies the term structure implications of a simple structural economy in which the representative agent displays ambiguity aversion, modeled by Multiple Priors Recursive Utility. Bond excess returns reflect a premium for ambiguity, which is observationally distinct from the risk...

We develop a continuous time general equilibrium yield curve model under ambiguity aversion. Even a moderate level of 'aggregate ambiguity' affects significantly the term structure and can drive the prices of common interest rate derivatives toward the patterns observed in fixed income markets....

We study an equilibrium asset pricing model with several Lucas (1978) trees subject to persistent distress events, where the agent has incomplete information about the state of an underlying common factor and learns from the events occurring to each tree. Contrary to similar asset pricing models...

We study an equilibrium asset pricing model with several Lucas (1978) trees subject to event risk, that is, the possibility that trees experience unexpected disasters. We exploit the market clearing mechanism, in the presence of multiple positive net supply assets, to show that the implications...

We develop a new framework for intertemporal portfolio choice when the covariance matrix of returns is stochastic. An important contribution of this framework is that it allows to derive optimal portfolio implications for economies in which the degree of correlation across different industries,...

We develop a new approach for evaluating performance across hedge funds. Our approach allows for performance comparisons between models that are misspecified – a common feature given the numerous factors that drive hedge fund returns. The empirical results show that the standard models used in...

We develop a novel approach to jointly examine skill, scale, and value added across individual funds. We find that the value added is (i) positive for the vast majority of funds, and (ii) close to its optimal level after an adjustment period possibly due to investors' learning. We also show that...
