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 Indian stock returns. We find that cross-sectional mean returns are explained by exposures to these three factors, and not by...

We introduce an alternative version of the Fama-French three-factor model of stock returns together with a new estimation methodology. We assume that the factor betas in the model are smooth nonlinear functions of observed security characteristics. We develop an estimation procedure that...

I set out a new method for estimating true (Konüs) PPPs. Household consumption per head deflated by these PPPs answers the question: by how much must the average expenditure per head of poor country A be increased to enable the typical inhabitant of A to enjoy the same utility level as the...

International studies have shown evidence on inequity in use of health services of different kinds, depending on the type of health care service analysed. However, equity in the access to long-term care (LTC) services has received much less attention. We investigate the determinants of several...

Executive summary: The report demonstrates that health and wellbeing policies at Royal Mail Group have had a number of significant and material effects:  Royal Mail Group has successfully tackled the issue of absenteeism (CHAPTER ONE): Royal Mail achieved significant reductions in absence –...

I study the cross sectional variation of stock returns and technological progress using a dynamic equilibrium model with production. In the model, technological progress is en- dogenously driven by R&D investment and is composed of two parts. One part is product innovation devoted to creating...

Background A healthy diet is associated with reduced risk of diabetes, cardiovascular disease and cancer. The study aimed to evaluate the cost-effectiveness of a universal strategy to promote healthy diet through brief intervention in primary care. Methods The research was informed by a...

This paper proposes an empirically feasible method for correcting the path-dependence bias of chain indices of the cost of living. Chain indices are discrete approximations to Divisia indices and it is well known that the latter are path-dependent: the level of a Divisia index is affected not...
