MIIHD is the newly established DFG research unit on “Macroeconomic Implications of Intra-Household Decisions” at the Faculty of Economics and Business composed of a core group of six researchers: Georg Dürnecker, Nicola Fuchs-Schündeln, Zainab Iftikhar, Leo Kaas (deputy), Chiara Lacava and Alexander Ludwig (spokesperson). Our main research goal is to enrich our understanding of intra-household decisions for macroeconomic outcomes, and how those and government policy interventions through tax and transfer programs in turn affect intra-household decisions such as household formation, labor supply, savings and fertility decisions. Our research will build on sound microeconometric data analysis and theoretical models to develop quantitative structural models with heterogeneous populations to address the three-way feedback between intra-household decisions, policy and the macroeconomy with a specific emphasis on inequality, both within and across households.
