 During the years following her dissertation, the research of Anna Christensen came to concentrate on the law of Welfare Society, i.e.those parts of the legal system that are developed to protect everyday life of the common men and women; Labour Law, Housing Law and Social Security Law were all to become her domain and main fields of research.In "Disqualification from Unemployment Benefits" ("Avstängning från arbetslöshetsförsäkring"), from 1980, Christensen studied the Swedish rules on disqualification from unemployment benefits on the ground of refusal of work and other self-imposed unemployment.
