The “Corporate Taxation and Public Finance” Research Department addresses questions related to corporate taxation and empirical public economics within the broader context of economic integration. The overarching aim of research in this Department is to understand how high international mobility impacts sustainable tax and financial policies as well as the scope, structure and tasks of the public sector. The Research Department is a leader in Europe for the international comparison of tax burdens thanks to its tax analysis models, including the European Tax Analyzer. Special attention is devoted to European integration processes through the analysis of EU tax harmonisation, the eurozone’s fiscal condition, the federal division of responsibilities and fiscal governance. The Department’s research agenda generates concrete tax and fiscal policy recommendations, thus supporting ZEW’s guiding aim of studying the optimal performance of markets and institutions in Europe.
