This broad line of research embodies a variety of more specific research interests. All of them share basically the micro-econometric approach, but the questions posed in each of them differ to a great extent. More specific, we can divide this broad line on the following sub-topics: (1) Empirical Evaluation of Active Labour Market Policies, (2) Polarization and the Future of Jobs, (3) Women and the Labour Market, (4) The Economics of Immigration, (5) Life Conditions and Hapiness, and (5) Pensions.
