Many studies with different methods (CGE models, DSGE models, structural gravity equations) have recently evaluated EU's Single Market. The problem with all these studies is that they use complex models with data sets which are not replicable. The aim of this paper is to develop a simple EU...

When Ernst B. Haas presented neofunctionalism (NF) as the first theory of European integration in the late 1950s in his analysis of the European Coal and Steel Community his approach seemed both highly innovative and plausible. However, doubts were cast on its suitability following the apparent...

One of the most significant developments in the twenty-century world politics has been the foundation of European Community (EC), and its evolution into the European Union (EU). Now, the EU is a supranational entity that is composed of twenty-five member states while it will be twenty-seven with...

We consider a model of international unions where countries have heterogeneous preferences for integration and their integration decisions are strategic complements. We analyze equilibrium integration under different integration protocols and characterize the preferences of countries over...

It has become increasingly difficult to unite all member states behind policies that some of them consider desirable or necessary to further EU integration. Differentiated integration may be a solution for this, but also may complicate decision-making. This by raising national constitutional...

This report examines the nature, the limits and potential of the principle of integration as a two-way process of mutual accommodation between migrants and the receiving societies. It assesses the extent to which this key principle, which lays at the foundation of the EU framework on...

This paper investigates the welfare gains from European trade integration, and the role of comparative advantage in determining the magnitude of those gains. We use a multisector Ricardian model implemented on 79 countries, and compare welfare in the 2000s to a counterfactual scenario in which...

This article provides an overview of major theoretical concepts behind the process of European economic integration. At first, the classic theory of customs unions as formulated by Viner, Meade and others is explained taking also into account factor mobility in a customs union in the move...
