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...

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...

This paper proposes a linear option pricing model by imposing common market pricing on decentralized risk exposure estimates across option contracts underlying the same security. The model embeds historical moment estimators to anchor the breakeven contribution of each risk source. A...
