Gender equality in the labour market is a key topic in the Nordic cooperation on gender equality. The Nordic Council of Ministers has asked NIKK, Nordic Information on Gender, to coordinate the project Part-Time Work in the Nordic Region. The aim of the project is to shed light on and analyse part-time work in the Nordic region, develop reports and arrange conferences. During the Swedish presidency of the Nordic Council of Ministers in 2013, the project identified how part-time work affects the economic resources of women and men. This first report presents statistics on full- and part-time work and compares the effects of part-time work on pensions in the Nordic countries. Marianne Sundström, professor of labour economics at Stockholm University, and Alma Lanninger Wennemo, Master's student at Stockholm University, wrote the report on a request by NIKK.
