| Abstract: | Abstract. This paper surveys the recent political economy literature on countries' incentives to form international unions and/or to disintegrate in smaller jurisdictions. The main factors that affect these incentives are (i) economic integration, (ii) the international order, (iii) international spillovers and (iv) the institutional setting. Some implications are drawn for the current debate in Europe on the political effects of economic integration, on the enlargement process and on the distribution of prerogatives between the European Union and national governments. |
