With the Accounting for Transparency project, the DFG has, for the first time, approved a Collaborative Research Center with a business focus. Under the auspices of Paderborn University, TRR 266 looks at how accounting and taxation affect the transparency of companies and what impact a transparent self-representation of companies has on society. Are conventional instruments of accounting such as annual, quarterly and ad-hoc reports still up-to-date and can they adequately fulfill their information purpose? Are the means currently used to inform employees, investors and other stakeholders about a company’s true state still sufficient? The researchers at TRR 266 address these questions by analyzing in detail how regulations and corporate transparency affect our economy and society.
