Differentiated Integration in the EU - From the inside looking out. CEPS Paperbacks. January 2014

Flexibility might be convenient when it comes to accommodating member states’ differing socio-economic and political interests in an expanding EU. Yet, opt-outs, enhanced cooperation and cooperation between member states outside the EU’s legal framework are calling into question the boundaries of this constitutional, institutional and legal differentiation in an EU that is founded on common principles, with a specific legal order and common institutions.

The European Union as a System of Differentiated Integration: Interdependence, Politicization and Differentiation. IHS Political Science Series No. 137, 10 July 2014

This paper conceptualizes the European Union (EU) as a system of differentiated integration characterized by both variation in levels of centralization (vertical differentiation) and variation in territorial extension (horizontal differentiation) across policy areas. Differentiation has been a concomitant of deepening and widening and has increased and consolidated as the EU’s powers, policy scope, and membership have grown. Turning to explanation, the paper attributes the pattern of differentiated integration in the EU to the interaction of interdependence and politicization. Differentiation among the member states (internal differentiation) results from supranational integration under conditions of high interdependence and politicization. By contrast, external differentiation (the selective policy integration of non-member states) occurs in highly interdependent but weakly politicized policy areas. These constellations are illustrated in case studies of differentiation in the internal market, monetary union, and defence.

The European Union-an expanding security community? EU Diplomacy Paper 06/2012, August 2012

This paper investigates why and how the geographical scope of the security community centered around the European Union (EU) is expanding. It starts from the assumption that the EU itself is a ‘tightly-coupled mature pluralistic security community’. The analysis of the expansion of this peaceful area is based on the theoretical framework first designed by Karl Deutsch and later developed by Emmanuel Adler and Michael Barnett. Contrary to the logic of the adage ‘si vis pacem para bellum’, I argue that the security community is expanding because the EU’s own origins and self-perception are driven by an ambition to create lasting peace. The key mechanisms I explore are the EU’s enlargement and neighborhood policies, which are best understood when analyzed against the concept of concentric circles: the regional EU-centered security community is a multi-speed security community, stronger at its core and weaker as it spreads towards its margins.

Federation without federalism. Relations between Moscow and the regions. OSW Study 49/2014

The regions of the Russian Federation are immensely diverse economically and geographically as well as when it comes to their national identity, civic awareness and political activity. We are in fact dealing with a ‘multi-speed Russia’: along with the post-industrial regions with their higher living standards and a need for pluralism in politics, there are poverty-stricken, inertial regions, dependent on subsidies from the centre. As a result of the policy of centralisation pursued by the Kremlin since 2000, the autonomy of the regions has been reduced fundamentally. This has affected the performance of the regional elites and made it difficult for the regions to use their natural advantages (such as resources or location) to their benefit. One of the effects of this policy has been the constantly decreasing number of the donor regions. The current model promotes the role of the region as a passive supplicant, for whom it is easier to seek support from the central government, offering loyalty in exchange, than to implement complex systemic reforms that would contribute to long-term development. Moscow’s control (political, economic and administrative) over the regions is currently so thorough that it contradicts the formally existing federal form of government in Russia.

Efficient taxation of multi-national enterprises in the European Union. Bruges European Economic Policy (BEEP) Briefing 5/2003

Current arrangements for multi-national company taxation in EU are plagued by severe conceptual and administrative problems, leading to high compliance costs, considerable uncertainty and ample room for abuse. Integration is amplifying these difficulties. There are two possible approaches in designing an efficient trans-border corporate tax system for the European Union. The first is to consolidate the EU-wide operations of MNEs, using an agreed common base as the reference variable, and then to apportion this total tax base using some presumptive indicators of activity in each tax jurisdiction – hence, implicitly, of the likely benefits stemming from each location. The apportionment formula should respect requisites of neutrality between productive factors and forms of corporate financing. A radically different approach is also available that offers considerable advantages in terms of efficiency, simplicity and decentralisation, including full administrative autonomy of national tax authorities. It entails abandoning corporate income as the relevant tax base and taxing at a moderate rate some agreed measure of business activity such as company value added, sales or employment. These are the variables usually considered in formula apportionment, but they would apply directly without having first to go through the complications of EU-wide consolidation based on a common-base definition. Reference to a broad base, with no exemptions or deductions, would allow to set low statutory rates.
