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...

This study investigates reference-dependent choice with a stochastic, state-dependent reference point. The optimal reference-dependent solution equals the optimal consumption solution (no loss aversion) if the reference point is selected fully endogenously. Given that loss aversion is...

This paper considers a general-equilibrium model with loss-aversion in consumption and heterogeneity: there is a continuum of agents, with s-shaped utility, who differ in the time-varying reference level of consumption. Heterogeneity in the reference level is crucial for the existence of the...

We test the dynamic aspects of the loss aversion feature of Kahneman and Tversky (1979) and find that idiosyncratic volatility is negatively associated with unrealized gains of stock returns. Moreover, we show that this negative relationship is stronger for stocks with high individual investors'...

We provide examples of pitfalls for parametric portfolio policies as introduced by Brandt, Santa Clara and Valkanov (RFS 2009). For the leading case of constant relative risk aversion (CRRA) strong assumptions on the properties of the returns, the variables used to implement the parametric...

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,...

Momentum strategies generate significant positive returns over long investment horizons; however these strategies experience infrequent periods of large negative returns. These periods are known as 'momentum crashes'. We demonstrate that the probability of a momentum crash is time-varying,...

We provide examples of pitfalls for parametric portfolio policies as introduced by Brandt, Santa Clara and Valkanov. For the leading case of constant relative risk aversion (CRRA) strong assumptions on the properties of the returns, the variables used to implement the parametric portfolio policy...

This paper studies the wealth and pricing implications of loss aversion in the presence of arbitrageurs with Epstein-Zin preferences. Loss aversion affects an investor's survival prospects mainly through its effect on the investor's portfolio holdings. Loss-averse investors will be driven out of...

This paper examines the life-cycle impact of preference factors as experience, loss aversion, and narrow framing on explaining the empirical low stock market participation, low stock share conditional on participation, and positive relationships between financial wealth and participation as well...
