We examine the empirical determinants of student achievement in higher education, focusing our attention on its small-group teaching component (classes or seminars) and on the role of attendance, number of students per class, peers, and tutors. The empirical analysis is based on longitudinal...

This paper analyses to what extent working conditions in foreign-owned firms differ from those in their domestic counterparts. It makes three main contributions. First, we replicate the consensus in the empirical literature by applying a standardised methodology to firm-level data for three...
