Corporate tax consolidation and enhanced cooperation in the European Union

We find that the consolidation is likely to yield a small aggregate welfare gain in Europe, but that not all countries benefit. A coalition of winning countries reduces the welfare gain and may induce a process of adverse selection that reduces the number of participating countries. We find that a coalition of similar countries (in terms of the size of their multinational sector) is more feasible in achieving agreement and is actually preferred by those countries over a European-wide reform.
