Unemployment has been one of the major problems in economic policy of our times. The main objective of the dissertation is to shed more light on the comprehensive influence of one of the most important domains in the life of human beings – one’s own work and employment status on individual life satisfaction. The four articles in this thesis explore and evaluate the psychological costs and the external effects of unemployment as well as the intangible impact of employment, respectively. The empirical analysis is thereby based on the life satisfaction approach.
