According to present-value models, a financial valuation ratio should predict future stock returns or cash flows but empirically shows little power. This paper develops insights about stock return predictability and reconciles the contradicting findings. We decompose a financial ratio into (1) a...

This paper proposes a novel semiparametric time-varying model for long-horizon predictive regressions in which the coefficients are allowed to change over time with unspecified functional forms. A linear projection method is employed to deal with the embedded endogeneity issue. We pursue an...

This paper proposes a system of semiparametric time-varying models for predictive regressions, where a locally stationary process in the form of time-varying autoregression is introduced to model varying-persistent predictors, and parameter instability and embedded endogeneity have also been...
