Sources of Wage Growth

Abstract

This paper investigates the sources of wage growth over the life cycle, determined by sectoral and firm mobility, unobserved ability, the accumulation of cognitive-abstract or routine-manual skills, and whether workers enroll in vocational training at the start of their career. Our analysis uses longitudinal administrative data over three decades and shows that routine-manual skills drive early wage growth, while cognitive-abstract skills become more important later. Moreover, job amenities are an important determinant of mobility decisions. Vocational training has long-term effects on career outcomes through various channels and generates returns for both the individual and society.
