This study analyzes changes in costs and prices from 1989 to 1997 for 1,767 short-term hospitals, including 204 hospitals involved in mergers; 653 hospitals that were rivals to these merging hospitals; and 910 nonmerging nonrival hospitals. We find that merging hospitals generally had lower growth in costs and prices compared with their rivals and also with nonmerging nonrival hospitals. We find that the presence and extent of these savings varied based on market and hospital conditions. However, our findings suggest that cost and price savings resulting from mergers may be smaller than estimated in earlier studies, especially through our comparison of merging hospitals with their rivals.
本研究分析了1989年至1997年间1767家短期医院的成本和价格变化，其中包括204家参与合并的医院；与这些合并医院存在竞争关系的653家医院；以及910家既未参与合并也不存在竞争关系的医院。我们发现，与竞争对手以及既未参与合并也不存在竞争关系的医院相比，参与合并的医院成本和价格的增长总体较低。我们发现，这些成本节约的存在与否及程度因市场和医院状况而异。然而，我们的研究结果表明，合并带来的成本和价格节约可能比早期研究估计的要小，尤其是通过我们将参与合并的医院与其竞争对手进行比较得出的结果。
