Employee Commitment and Wages in the Private Sector

This paper evaluates the link between employee affective commitment and wages using a theoretical model predicting that affective commitment and wages can be complements. We estimate simultaneous quantile regressions based on a matched worker–employer sample of private sector workers from the UK's Workplace Employment Relations Survey 2004. Our results suggest that wages increase with increasing levels of affective commitment, consistent with the idea that the two are complements.     

Disrupting an imposed racial identity or performing the model minority? The pursuit of postsecondary education by young African immigrant men in Southern Ontario,Canada

ABSTRACT

This article examines how young African immigrant men in Southern Ontario cope with the dominant racial identity at school in an effort to improve their academic performance and access postsecondary education (PSE). Critical race theory in education is employed to explain how the young men distance themselves from stereotypes about Black masculinity by regulating their own behaviour and differentiating themselves from their Caribbean immigrant peers. Sixty-seven young men who had immigrated to Southern Ontario from several African countries over the last 10 years were interviewed individually and in focus groups for the study. The findings suggest that the research participants adopted a model minority status within an educational system that clearly embodies racist and systemically oppressive frameworks.     

Estimation of Semiparametric Models when the Criterion Function Is Not Smooth

We provide easy to verify sufficient conditions for the consistency and asymptotic normality of a class of semiparametric optimization estimators where the criterion function does not obey standard smoothness conditions and simultaneously depends on some nonparametric estimators that can themselves depend on the parameters to be estimated. Our results extend existing theories such as those of Pakes and Pollard (1989), Andrews (1994a), and Newey (1994). We also show that bootstrap provides asymptotically correct confidence regions for the finite dimensional parameters. We apply our results to two examples: a ‘hit rate’ and a partially linear median regression with some endogenous regressors.

Natural cubic splines for the analysis of Alzheimer's clinical trials

Mixed model repeated measures (MMRM) is the most common analysis approach used in clinical trials for Alzheimer's disease and other progressive diseases measured with continuous outcomes over time. The model treats time as a categorical variable, which allows an unconstrained estimate of the mean for each study visit in each randomized group. Categorizing time in this way can be problematic when assessments occur off-schedule, as including off-schedule visits can induce bias, and excluding them ignores valuable information and violates the intention to treat principle. This problem has been exacerbated by clinical trial visits which have been delayed due to the COVID19 pandemic. As an alternative to MMRM, we propose a constrained longitudinal data analysis with natural cubic splines that treats time as continuous and uses test version effects to model the mean over time. Compared to categorical-time models like MMRM and models that assume a proportional treatment effect, the spline model is shown to be more parsimonious and precise in real clinical trial datasets, and has better power and Type I error in a variety of simulation scenarios.
