Vegard Skirbekk is a professor at Columbia Aging Center, Columbia University and a senior researcher at the Norwegian Institute of Public Health. He investigates trends in age and gender distribution of human capital, skills and work performance focusing on life cycle and cohort changes; and how to improve senior workers’ skills and capacities— an issue of paramount importance for many countries coping with challenges of an aging population. He studies the impact of generational and life cycle variation on societal values and belief structures, considering cohort and life cycle changes, migration, fertility differences and taking into account intrafamilial transmissions. Another key research interest is the determinants of childbearing in a low fertility Asian/European context. He has published in leading academic journals, including Science, Demography, and Population and Development Review.
