We show theoretically that when Bayesian investors face time-series uncertainty about assets' risk exposures, differences in their priors affect the pricing of risk in the cross-section: different priors for the same asset can generate differences in perceived risk exposures, and thereby...

It is well established that value stocks outperform glamour stocks, yet considerable debate exists about whether the return differential reflects compensation for risk or mispricing. Under mispricing explanations, prices of glamour (value) firms reflect systematically optimistic (pessimistic)...

This chapter focuses on the attitude of investors toward financial gains and losses and their decisions on wealth allocation, and how these changes are subject to behavioral factors. The focal point is the integration of behavioral elements into the classic portfolio optimization. Individual...

The literature on ‘cash flow' or ‘earnings' beta is theoretically well-motivated in its use of fundamentals, instead of returns, to measure systematic risk. However, empirical measures of earnings beta based on either log-linearizing the return equation or log-linearizing the clean-surplus...

We propose a nonparametric Bayesian approach for the estimation of the pricing kernel. Historical stock returns and option market data are combined through the Dirichlet Process (DP) to construct an option-adjusted physical measure. The precision parameter of the DP process is calibrated to the...

We examine the roles of rational and behavioural factors in explaining long-run premiums/discounts on closed-end funds, using evidence on equity funds from the US and UK. Although the processes by which fund prices converge towards long-run premiums or discounts are similar in the two countries,...

This paper studies the excess returns on stocks, associated to various company fundamentals on a panel of US stocks from 1979 to 2008. The returns premia are measured using a random coefficient panel data model on the individual stock level. We show that the HML and SMB factors in the Fama and...

Many papers claim that value and size fundamentals (book-to-price ratios and market capitalization) yield positive expected return premia because they are proxies for systematic risk factors in conditional and/or multi-factor CAPM. Much of empirical evidence to support this idea comes from...

This paper examines the time-series predictability of aggregate stock returns in 20 emerging markets. In contrast to the aggregate-level findings in US, earnings yield forecasts the time-series of aggregate stock returns in emerging markets. We consider aggregate earnings not as normalizing...

Bubbles can persist because investors are better off riding bubbles. We define bubbles in a natural way as significant, prolonged deviations from fundamental values measured by the well-known asset pricing models. Our real-time bubble detection system shows that –using US industry returns–...
