On 8 December, Prof. Dr. Christoph Spengel, together with Theresa Bührle and Leonie Fischer, was awarded the ZEW Förderkreis Prize for the best economic policy consulting project 2021/2022 for the study “Immediate Tax Programme and Approaches to Increase Entrepreneurial Investment in the Context of Corona Crisis in Germany” on behalf of the Friedrich Naumann Foundation for Freedom. The award ceremony took place within the framework of the ZEW series “Economic Policy at First Hand”. Ralph Rheinboldt congratulated the prize winners on behalf of the ZEW Förderkreis.

The study examines how efficient and targeted the income tax measures were in supporting German firms affected by the Corona crisis. The results show that the Corona tax aids in Germany were altogether too timid to cushion the consequences of the crisis. Thus, the measures in their form at the time mainly relieved large companies, while small companies and start-ups hardly benefited. The extension of the loss carryback period to two years, which was called for in the study, has now been implemented.

The transfer of knowledge as well as the dialogue between science and practice on this highly topical issue was not only promoted by appropriate media coverage, but also facilitated interesting discussions within the framework of the formats “Leibniz in the Bundestag” and “Book a Scientist”. Synergies from the discussion of tax legislation in the crisis were additionally used for a subsequent scientific project, which has since been published in an international journal, the British Tax Review.
