This paper develops a new estimation procedure for characteristic-based factor models of security returns. We treat the factor model as a weighted additive nonparametric regression model, with the factor returns serving as time-varying weights, and a set of univariate non-parametric functions...

This study empirically examines the Fama-French three-factor model of stock returns for India. We find evidence for pervasive market, size and book-to-market factors in India stock returns. We find that cross-section means returns are explained by exposures to these three factors, and not by the...

This paper estimates a structural times series model of return volatility. We argue that the structural time series approach to GARCH modelling first suggested by Engle and Lee, has the potential to improve the empirical reliability of GARCH models, and greatly enhance their interpretability. In...

This paper develops a new estimation procedure for characteristic-based factor models of stock returns. It describes a factor model in which the factor betas are smooth nonlinear functions of observed security characteristics. It develops an estimation procedure that combines nonparametric...
