This paper studies asset pricing implications of heterogeneity across capital inputs. We build a general equilibrium model including two types of capital. The agents in our economy have Epstein and Zin (1989) preferences and technology is exposed to long-run risks in productivity growth....

We study the implications of the quality of information about the business cycle for the pricing of defensive and cyclical stocks in a general equilibrium framework. We rely on a two-tree Lucas-style endowment economy in which the business cycle is modeled as an unobservable mean reverting...

We show that the widely documented negative relation between idiosyncratic volatility (IVOL) and expected returns can be explained by the mean reversion of stocks' idiosyncratic volatilities. We use option-implied information to extract the mean reversion speed of IVOL in an almost model-free...

This paper breaks the correlation risk premium down into two components: a premium related to the correlation of continuous stock price movements and a premium for bearing the risk of co-jumps. We propose a novel way to identify both premiums based on dispersion trading strategies that go long...

We analyze the optimal stock-bond portfolio under both learning and ambiguity aversion. Stock returns are predictable by an observable and an unobservable predictor, and the investor has to learn about the latter. Furthermore, the investor is ambiguity-averse and has a preference for investment...
