This paper discusses the eastward enlargement process of the EU in the framework of a simple war of attrition bargaining game. Both players – the existing EU members and the applicants – benefit from enlargement, yet for the applicants reform to the acquis is costly, while the EU prefers substantially reformed candidates. A waiting game unfolds. Within this framework the present enlargement round is analyzed and policy results are deduced. For example, it is shown that delegating the evaluation of applicants to a third party, compensating applicants for their reform efforts or increasing the benefits for new members are all effective negotiation strategies for the EU that have been applied in the process.
