Empirical studies on the effect of bank mergers and the geographical segmentation of regional bank deposit markets in Japan

本项目的研究成果由三部分组成。在第一部分中，我找到了支持日本银行业市场地理分割的经验证据。在第二部分，我调查了银行合并对借款人的影响，发现合并可能导致贷款人议价能力的提高，使借款人的借贷成本更高。在第三部分中，我半理性地评估了公共债务市场在减少银行议价能力带来的负面影响方面的作用。

The research output from this project consists of three parts. In the first part, I find empirical evidence that supports that the Japanese banking markets are geographically segmented. In the second part, I investigate the effects of a bank merger on borrowers and find that increases in lenders’ bargaining powers possibly caused by mergers make borrowers’ borrowing costs more costly. In the third part, I assess the role of public debt markets in reducing negative effects arising from banks’ bargaining powersempirically.
