Welcome to the webpage of the BMBF research project GRETCHEN!

Note: The project ran from March 2012 to September 2015.

GRETCHEN investigates the impact of climate, renewable energy and innovation policies (the "policy mix") on technological and structural change in renewable power generation technologies. GRETCHEN uses an innovative research design based on three pillars: the combination of environmental and innovation economics, a multi-method approach and an integrated analysis on three empirical levels. These three are: a micro-level, which examines the influence of the policy mix on company-internal invention, innovation and diffusion; a meso level, which addresses the impacts on innovation networks and market structures; and a macro level, which derives macroeconomic statements by endogenizing technological change. The project results and the derived policy recommendations for designing the policy mix are addressed to decision-makers from academia, politics and industry.

The project acronym "GRETCHEN" reflects the title of the research project:
The impact of the German policy mix on technological and structural change in renewable power generation technologies

The project was conducted by researchers from the Fraunhofer Institute for Systems and Innovation Research (Fraunhofer ISI), the Institute of Economic Structures Research (GWS mbH) and the Friedrich-Schiller-University Jena (FSU Jena) and coordinated by Fraunhofer ISI and ran from March 2012 until September 2015.

GRETCHEN was being funded by the Federal Ministry of Education and Research (BMBF) within its funding priority "Economics of Climate Change" and administered by the unit Environment, Culture, Sustainability in the German Aerospace Center Project Management Agency (PT-DLR).
