Research description

Harpa´s doctoral work focuses on retirement and socioeconomic position in relation to health in old age. The overall aim of the thesis is 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.
