We show how to use conditioning information optimally to construct a sharper unconditional Hansen-Jagannathan (1991) bound. The approach in this paper is different from that of Gallant, Hansen and Tauchen (1990), but both approaches yield the same bound when the conditional moments are known....

We study asset pricing implications of return extrapolation in a Lucas economy. We find that the effect of extrapolation is mainly on short rates rather than risk premia, time variation in expected returns is mainly driven by time-varying short rates, and return volatility can be lower than...

Although liquidity has received wide attention in asset pricing literature over the past decades, how stock liquidity is priced in emerging markets remains unclear. We find that liquidity plays an important role in explaining the cross-section and time-series variation in expected returns by...

While many studies document that the market risk premium is predictable and that betas are not constant, the dividend discount model ignores time-varying risk premiums and betas. We develop a model to consistently value cashflows with changing risk-free rates, predictable risk premiums and...
