本研究采用基于成本和利润函数的随机元前沿方法，研究了合并如何影响日本具有代表性的合作金融机构shinjin银行效率的地区差异。研究结果支持了宁静生活假说，即效率调整的Lerner指数与成本效率之间存在显著的负相关关系。相反，市场支配力与利润效率之间的关系始终是正的。此外，未参与并购的独立欣金银行的成本和利润效率高于其他银行，这表明并购会降低效率。
This study investigates the regional differences in how consolidation has affected the efficiency of Shinkin banks, a representative cooperative financial institution in Japan, using the stochastic meta‐frontier approach based on cost and profit functions. The findings support the quiet life hypothesis that a significant negative relationship exists between efficiency‐adjusted Lerner indices and cost efficiency. By contrast, the relation between market power and profit efficiency is consistently positive. Moreover, independent Shinkin banks not involved in mergers exhibit higher costs and profit efficiency than other banks, suggesting that mergers can deteriorate efficiency.
