Martijn Nouwen’s dissertation analyzed the functioning and effectiveness of the political EU Code of Conduct, and its governing body: the diplomatic EU Code of Conduct Group, in the fight against tax avoidance by multinational companies and against the facilitation thereof by harmful tax competition between Member States. Its uniqueness lies in its empirical approach, by evaluating how the Group has operated in practice – from both a governance and output/result perspective – by analyzing more than 2,500 internal EU-documents obtained through FOI-requests, complemented with interviews with insiders. In addition to tax law, he used other relevant disciplines in his research – such as EU law, economics, and political science – to ensure a comprehensive approach. His dissertation concludes that the Group has achieved impressive results in tackling harmful tax practices, but also that many forms of unfair tax competition have not been adequately addressed. It contains recommendations for improvement. Nouwen shared his findings with members of national Parliaments and the European Parliament. Several media reported about his PhD-research (e.g., Trouw, Het Financieele Dagblad, NOS-Journal and Zembla). This political and societal attention encouraged policymakers to reform the Group.
