We examine asset prices in a representative-agent model of general equilibrium. Assuming only that individuals are risk averse, we determine conditions on the changes in asset risk that are both necessary and sufficient for the asset price to fall. We show that these conditions neither imply,...

This paper assesses the quantitative impact of ambiguity on historically observed financial asset returns and growth rates. The single agent, in a dynamic exchange economy, treats the conditional uncertainty about the consumption and dividends next period as ambiguous. We calibrate the agent's...

This paper shows the success of valuation risk-time‐preference shocks in Epstein-Zin utility-in resolving asset pricing puzzles rests sensitively on the way it is introduced. The specification used in the literature is at odds with several desirable properties of recursive preferences because...

The rare disaster hypothesis suggests that the extraordinarily high postwar U.S. equity premium resulted because investors ex ante demanded compensations for unlikely but calamitous risks that they happened not to incur. While convincing in theory, empirical tests of the rare disaster...

I generalize the long-run risks (LRR) model of Bansal and Yaron (2004) by incorporating recursive smooth ambiguity aversion preferences from Klibanoff et al. (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model is as tractable but more flexible...

Returns to both traditional and risk-managed momentum strategies are non-normal, reducing the efficacy of the Sharpe ratio as an evaluation tool. To account for the higher moments of the return distribution, we evaluate momentum using the framework of myopic loss aversion. Under this framework,...

We evaluate whether machine learning methods can better model excess portfolio returns compared to the standard regression-based strategies generally used in the finance and econometric literature. We examine 17 benchmark factor model specifications based on Expected Utility Theory and theory...

The last 30 years saw substantial increases in wealth inequality and in stock market participation, smaller increases in consumption inequality and the fraction of indebted households, a decline in interest rates and in the expected equity premium, as well as a prolonged stock market boom....

The large spread between equity returns and risk-free rates (the "equity premium puzzle") has been the subject of intense debate. Two main families of models claim to solve this puzzle: habit-formation models and loss-aversion models. The goal of this paper is to assess empirically which of them...

The biggest and most well-known unsolved problem in academic finance is famously referred to as the Equity Premium Puzzle. It refers to the unexplained phenomenon that for over 100 years the average return on a well-diversified portfolio of equities has far outperformed that of risk-free,...
