We show that a business-cycle component of consumption growth (dubbed business-cycle consumption) with cycles between 2 and 4 years is effective in explaining the differences in risk premia across alternative test assets, including recently-proposed anomaly portfolios. We formalize the mapping...

We formulate a stylized model that admits volatility ambiguity to the Lucas framework. The model specifies an economically motivated ambiguity penalty function that makes volatility ambiguity quantifiable with χ2-statistics, and allows for analytical solutions. The addition of volatility...

We decompose the standard consumption beta into two components that measure consumption risk in high and low economic activity states. Recessionary consumption risk commands a positive and statistically significant compensation, while the market price of expansionary consumption risk is not...

Risk-averse expected utility maximization implies that the pricing kernel must be a non-increasing function of aggregate wealth. However, empirical research has found that the pricing kernel frequently displays a locally increasing portion in aggregate wealth. This is known as the pricing kernel...

I propose a parsimonious econometric model for the stochastic process governing the evolution of per capita consumption and stock market dividend over time. The model features stochastic volatility of consumption and dividend growth rates, and time-varying likelihood of rare disasters. I embed...

In this paper, we examine how learning about disaster risk affects asset pricing in an endowment economy. We extend the literature on rare disasters by allowing for two sources of uncertainty: (1) the lack of historical data results in unknown parameters for the disaster process, and (2) the...
