This article develops a novel nonparametric time-varying auto-regressive distributed-lag model to estimate and test the persistence of inflation. To characterize the temporal instability of persistence in the inflation process, our proposed model allows for time-varying coefficients with...

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...
