This paper investigates the impact of international bank flows from G10 lender countries on income inequality in 74 borrower countries over 1999–2013. Specifically, we examine the role of international bank flows contingent upon the Basel 2 capital regulation and the level of financial market development in the borrower countries. First, we find that improvements in the borrower country risk weights due to rating upgrades under the Basel 2 framework significantly increase bank flows, leading to improvements in income inequality. Second, we find that the level of financial market development is also important. We report that a well-functioning financial market helps the poor access credit and thereby reduces inequality. Moreover, we employ threshold estimations to identify the thresholds for each of the financial development measures that borrower countries need to reach before realizing the potential reductions in income inequality from international bank financing.

本文调查了十国集团（G10）贷款国的国际银行资金流入对74个借款国在1999-2013年间收入不平等的影响。具体来说，我们考察了国际银行资金流动的作用，具体取决于巴塞尔协议2的资本监管以及借款国的金融市场发展水平。首先，我们发现，由于在《巴塞尔协议2》框架下进行的评级升级，借款国风险权重的改善显着增加了银行流量，从而导致收入不平等的改善。其次，我们发现金融市场的发展水平也很重要。我们报告说，运作良好的金融市场有助于穷人获得信贷，从而减少不平等现象。而且，
