Fiscal responsibility is currently high on both the political as well as the academic agenda. More and more national and supra-national legislation is aimed at achieving a fair tax contribution for everyone. Think of the recent legislation on minimum taxation of 15% and the public Country-by-Country reporting for large multinational companies. However, there are many challenges that companies face in complying with these new regulations. In additon, it is also necessary to study the effectiveness of these new regulations and to develop metrics to measrue the performance of companies in terms of fiscal responsiblity. This project aims to make an academic contribution to this social/academic debate.
