Ania Thiemann is a Competition Expert and former Head of Global Relations at the OECD’s Competition Division. She is an expert in regulatory impact assessment and conducts research on the digital economy and digital disruption of financial markets, as well as the regulated professions. She is currently managing a regulatory impact assessment in Brazil (Competition Assessment Review), reviewing two sectors of the Brazilian economy to identify and analyse regulatory barriers to competition in the sectors. The project will lead to recommendations for regulatory change to stimulate economic growth and enhance consumer welfare. A similar project in Iceland was successfully concluded in November 2020 and led to recommendations that could yield up to 1% of GDP in benefits.
