Banks entering into a mega-bank enjoy large and highly statistically significant excess returns. However, the size of the merger does not seem to affect longer-term measures of performance. Using synthetic control method, we are able to conduct difference-in-difference analysis and find that acquiring banks become statistically significantly less profitable, less solvent, and more inefficient after a merger event than the control group. These findings suggest that the benefits accruing to shareholders of mega-merger banks are not due to newly created business synergies, but perhaps a "flight-to-safety" on the part of shareholders.

加入大型银行的银行享有巨大的、具有高度统计意义的超额收益。然而，合并的规模似乎并不影响长期业绩指标。使用综合控制方法，我们能够进行差异中的差异分析，并发现，收购银行变得更少的利润，更少的偿付能力，更低的效率比控制组的合并事件后，统计上显着。这些研究结果表明，大型合并银行的股东所获得的利益并不是因为新产生的业务协同效应，而是股东的“避险”。
