I examine a continuous-time intertemporal consumption and portfolio choice problem under ambiguity, where expected returns of a risky asset follow a hidden Markov chain. Investors with Chen and Epstein''s (2002) recursive multiple priors utility possess a set of priors for unobservable...

We examine a real option model with governance friction and optimal investment and financing decisions when an entrepreneur facing ambiguity considers investing in an innovation project. The novel features of our model are the introduction of jumps in the returns to innovation and investors’...

We examine a production-based asset pricing model with regime-switching productivity growth, learning and ambiguity. Both mean and volatility of the growth rate of productivity are assumed to follow a Markov chain with an unobservable state. The agent's preferences are characterized by the...

This paper explicitly solves, in closed form, the optimal consumption and portfolio choice for an ambiguity averse investor in a Merton-type two assets economy where a risk premium follows a mean-reverting process. The investor's preferences are represented by the recursive multiple priors...

In this article, we examine both pre- and post-reform economic convergence behaviour in China using the time-series procedures developed in the Hobijn and Franses (2000). Our results are striking: First, we find a number of extremely small convergence clubs for both the pre- and post-reform...

We study a production economy with regime switching in the conditional mean and volatility of productivity growth. The representative agent has generalized disappointment aversion (GDA) preferences. We show that volatility risk in productivity growth carries a positive and sizable risk premium...
