Do Institutional Changes Make a Difference? A veto player analysis of how institutional changes in the Council of the EU influence legislative efficiency and outputs. Brugges Political Research Paper No. 31, October 2013

A driving argument behind recent EU treaty reforms was that more qualified majority voting (QMV) was required to reduce the potential dangers of legislative paralysis caused by enlargement. Whilst existing literature on enlargement mostly focuses on the question of what changed in the legislative process after the 2004 enlargement, the question of why these changes occurred has been given far less attention. Through the use of a single veto player theoretical model, this paper seeks to test and explain whether enlargement reduces the efficiency of the legislative process and alters the type of legislation produced, and whether QMV can compensate for these effects. In doing this, it offers a theoretical explanation as to why institutional changes that alter the level of cohesion between actors in the Council have an influence over both the legislative process and its outcomes.

What strategy for a genuine Single Market? CEPS Special Report No. 126/January 2016

This strategy paper focuses on making the most of the EU single market. The EU should pursue a genuine single market, and treat it as a common asset of all its citizens, economic operators and member states. The economic case to be made on behalf of the genuine single market is powerful and even more so due to the findings of recent empirical economic research. However, only the genuine single market can realise the expectations of such large gains. Weak, ‘feasible’ action plans cannot! The strategy is based, first of all, on a clear design of the genuine single market and subsequently concentrates on ‘what it takes’. Ten types of actions sum up ‘what it takes’: five at the EU level, four at the EU-member state interface, and finally, the realisation of legitimacy and acceptance.

Pre-empting technical barriers in the Single Market. CEPS Policy Brief No. 277, 11 July 2012

Effective enforcement and compliance with EU law is not just a legal necessity, it is also of economic interest since the potential of the Single Market will be fully exploited. Enforcement barriers generate unjustified costs and hindrances or uncertainty for cross-border business and might deprive consumers from receiving the full benefit of greater choice and/or cheaper offers. The EU has developed several types of enforcement efforts (preventive initiatives, pre-infringement initiatives and formal infringement procedures). More recently, the emphasis has been placed on effective prevention. This CEPS Policy Brief analyses the functioning of one preventive mechanism (the 98/34 Directive) and assesses its potential to detect and prevent technical or other barriers in the course of the last 25 years. Based on an empirical approach, it shows that this amazing mechanism has successfully prevented thousands of new technical barriers from arising in the internal goods market.
