Evaluation Model for Integrated Tax and Transfer Policy Analyses

The ZEW-EviSTA, Evaluation Model for Integrated Tax and Transfer Policy Analyses, has been advising public clients on the distributional effects and design of taxes and transfers for many years. Our topic page presents the functioning of the model, current research results as well as facts and figures on the German tax-transfer system.

Europe

European Integration

Refugee and debt crisis, Brexit, climate change – Europe is facing numerous challenges. National solo efforts to solve these problems are not enough.

Mannheim Innovation Panel

Since 1993, the ZEW has been collecting annual data on the innovation behaviour of German companies – from new products and processes to investments and obstacles. The surveys are commissioned by the Federal Ministry of Education and Research (BMBF). The ZEW Innovation Survey provides valuable insights into Germany's technological performance and serves as a basis for political and economic decisions.
