We examined a large sample of Polish science, technology, engineering, mathematics, and medicine (STEMM) scientists (N = 16,083) to study rank advancement and productivity in the past 40 years. We used two previously neglected time dimensions -- promotion age and promotion speed -- to construct individual lifetime biographical and publication…

Gender pay gaps in earnings are well-documented in the literature. However, new factors contributing to women's lower earnings have emerged and remain under-researched. Educational choices are among them. We use a rich administrative dataset from Poland, a Central Eastern European country with high tertiary education enrolment and high female…

Recently, there has been a massive trend of Chinese international PhD graduates returning to China's research-intensive universities that are undergoing systemic reforms and aspire to flourish in the global higher education field. Taking into account this changing academic environment and field-specific mobility patterns, the study examines the…

This paper examines the potential earnings premium associated with a doctoral degree (PhDs, ISCED9) over postgraduate degrees (PGs, or Masters, ISCED7) in the UK. We assess this premium using a decade-worth of UK Labour Force Survey data (2011-2020). To explore the possible endogenous choice of post-graduate tracks, this paper deploys linear…

Drawing upon data on the entire population of French STEM PhD students, we explore the factors leading PhDs to pursue independent research from their supervisors during the PhD and how independence links to their career outcomes. We find that independence is significantly associated with students' and supervisors' characteristics. Moreover,…
