Can Supranational Infrastructure Regulation Compensate for National Institutional Weaknesses?

We study the impact of institutional characteristics of national and supranational regulation on the effectiveness of both types of regulation. We focus on four institutional dimensions: regulatory capacity, accountability, commitment and fiscal capacity. We show how supranational regulation may reduce or worsen the challenges imposed by national institutional weaknesses. The analysis allows an identification of the costs and benefits of supranational regulation in very diversified institutional contexts. It also explains why some desirable changes from a global welfare perspective are unlikely to take place unless the losers of market integration are somehow compensated when national regulation is unlikely to do so as a result of some of its weaknesses.
