Nadine Riedel on the effectiveness of countermeasures against multinational tax avoidance

Nadine Riedel presents at the WIDER Seminar Series on 29 November 2023.

How effective are countermeasures against multinational tax avoidance – new evidence from South Africa


Recent decades have seen unprecedented government actions to combat international tax avoidance of multinational firms. Yet, the effectiveness of anti-tax avoidance measures is largely unclear. In this project, we rely on exceptionally rich tax-administrative data from South Africa to determine the impact of a specific type of anti-profit shifting rule—measures again strategic mis-pricing of intra-firm trade—on multinational firm behavior. We document that the rules are effective in constraining tax-strategic trade mis-pricing. Their effects on multinational firms’ overall profit reporting and corporate tax payments in South Africa are nevertheless only moderate, suggesting that firms find alternative ways to reduce their effective tax burden.

WIDER Seminar Series

The WIDER Seminar Series showcases the latest research on key topics in development economics. It provides a forum for senior and early-career researchers, both in-house and external, to present recent and ongoing work related to UNU-WIDER’s current work programme.

In addition to providing a forum for both academic debate and training, the series presents an opportunity for policy makers and others interested in development to learn about the latest research methods and findings.

The WIDER Seminar Series events take place on Wednesdays. All those interested are invited to register and attend via Zoom or in person.
