The TRR 266 Accounting for Transparency is a trans-regional Collaborative Research Center funded by the German Research Foundation (Deutsche Forschungsgemeinschaft – DFG). Our team of more than 100 dedicated researchers examines how accounting and taxation affect firm and regulatory transparency and how regulation and transparency impact our economy and society. We intend to help develop effective regulation for firm transparency and a transparent tax system. Naturally, we also ensure transparency of our own research.
