Estimating and comparing the competitiveness of banking industry

早些时候的论文表明，现有的竞争衡量标准不能正确识别竞争力。在这个项目中，我们使用Boone指标来评估银行业的竞争力，不仅是在日本，在许多国家也是如此。比较布恩指标和其他竞争指标，这些指标的变动趋势是相同的，而布恩指标的波动幅度比其他指标更大。我们还模拟了Boone指标的表现，结果表明边际成本利润弹性要好于其他方法。

Earlier papers show that the existing measures of competitioncannot identify competitiveness properly. In this project, we use Boone indicator to estimate the competitiveness for banking industry not only in Japan but also in many countries. Comparing Boone indicator with other measure of competition, the movement of these indicators are the same, while Boone indicator fluctuates greater than the others. We also simulate the performance of Boone indicator and show that the marginal-cost elasticity of profit is better than the other approaches.
