Research description

Harpa’s main fields of interest are in social stratification, social gerontology, health inequalities, life course studies, causal inference and quasi-experimental methodology. 

Harpa’s research work focuses on retirement and socioeconomic position in relation to health in old age. The overall aim of the PhD project was to empirically study how retirement processes are influenced by health status, social position and gender in Sweden and Europe using nationally representative data sources, and in turn how the timing of the labour market exit influences health and functioning at old age. Postdoctoral research is a continuation of the PhD project, with focus on early retirement and health.
