Research focus

I empirically investigate how the regulation of taxes and reporting affects firms and their stakeholders. My research findings should contribute to local and international debates and inform evidence-based regulation of firms and markets. I find it important that legislators, standard-setters, and regulators can make better decisions based on empirical results, e.g., to enact more efficient laws with fewer unexpected or unintended side effects and consequences.
