Current research projects

  • Judicial networks as market regulation
    How do and should courts from different countries interact with each other? Specifically, how far is it possible to identify a citation network between the highest courts in Europe in private law?
  • Private international law of companies in Europe
    How far do conflict of laws rules applicable to companies drive regulatory competition in this area of law? Should the EU provide common rules?
  • Law, finance and development
    What are the mechanisms by which legal institutions influence financial systems and thereby affect economic development? How can quantitative methods be used in a fruitful way in order to answer this question?
  • Comparative law
    What should be the future of comparative law? In particular: how can we ‘update’ both the methods and the themes of comparative law in order to provide meaningful contextual comparisons of law today?
