We propose a novel one-sector stochastic growth model, where producitivity growth follows a Markov-switching process with two regimes, and where households have generalized recursive smooth ambiguity preferences. The adopted class of preferences permits a three-way separation of risk aversion,...

Campbell, Serfaty-De Medeiros, and Viceira (2010) propose an optimized method to hedge currency risk in portfolios of international equities. In a demanding out-of-sample test, incorporating transaction and rebalancing costs, and margin requirements we find their method reduces risk in real...

We develop a real options model in which a firm exposed to seasonal variations in its output price is able to produce output, store it, and sell it later, separating the production and selling decisions. The model suggests that the optimal policy for a firm with low inventory costs is to spread...

We examine the time-series risk-return trade-off among equity factors. We obtain a positive trade-off for profitability and investment factors. Such relationship subsists conditional on the covariance with the market factor, which represents consistency with Merton's ICAPM. Critically, we obtain...

We offer evidence that exposures to consumption growth, expected consumption growth, and consumption volatility are significantly priced in the cross-section of delta-hedged option and straddle returns. Consumption growth and expected consumption growth command a positive risk premium, whereas...

We examine asset allocation decisions under smooth ambiguity aversion when an investor has a prior degree of belief in an asset pricing model (e.g., the domestic CAPM). Different from a Bayesian approach, the investor separately relies on the conditional distribution of returns and on the...

We propose a novel one-sector stochastic growth model, where producitivity growth follows a Markov-switching process with two regimes, and where households have generalized recursive smooth ambiguity preferences. The adopted class of preferences permits a three-way separation of risk aversion,...

I develop a stochastic growth model with production where there is a hidden state governing productivity growth regimes, and the hidden state evolves according to a Markov chain. Economic agents learn about the hidden state and display ambiguity aversion in the spirit of Klibanoff et al. (2005)....

We use the Bayesian method introduced by Gallant and McCulloch (2009) to estimate consumption-based asset pricing models featuring smooth ambiguity preferences. We rely on semi-nonparametric estimation of a flexible auxiliary model in our structural estimation. Based on the market and aggregate...

We test the relevance of technical and fundamental variables in forming currency portfolios. Carry, momentum and reversal all contribute to portfolio performance, whereas the real exchange rate and the current account do not. The resulting optimal portfolio outperforms the carry trade and other...
