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...

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...

In the analysis of microarray data, and in some other contemporary statistical problems, it is not uncommon to apply hypothesis tests in a highly simultaneous way. The number, N say, of tests used can be much larger than the sample sizes, n, to which the tests are applied, yet we wish to...

This article addresses the issue of termination of employment because of the conduct of the employee in her leisure time, in the light of the human right to private life. It explores the impact on the retention of employment of activities taking place outside the workplace and outside working...

Based on a case study of Saudi Arabia's WTO accession, the article offers a critique of conventional factor- and sector-based models of trade policy, proposing instead a two-level institutional account that is likely to be relevant for non-democratic states in general. Historically grown...

CEO incentive contracts are commonplace in China but their incidence varies significantly across Chinese cities. We show that city and provincial policy experiments help explain this variance. We examine the role of two policy experiments: the use of Special Economic Zones (SEZs) to attract...
