The panel calls for research on the impact and consequences of migration for the receiving countries’ political politics, understood broadly so to include impact on variables important for the development of all kinds of social and economic policies and institutions. Potential papers might deal with the impact of migration on welfare or social policy reform, the power-resources of unions, employers or political parties or might analyze the consequences of migration for host countries’ labor markets or welfare programs. The panel is especially interested in studies addressing a core question of the current academic debate: Is migration moving the (mainly) coordinated political economies of Europe into a more market-liberal direction? We are interested in contributions using both formal and non-formal theoretical approaches, as well as both quantitative and qualitative research methods. In addition to theoretically guided empirical research, we also welcome submissions that focus on predominantly theoretical or methodological advancements in the field.
