评估美国银行业中的共同所有权假说
Assessing the Common Ownership Hypothesis in the US Banking Industry
摘要
We assess the common ownership hypothesis (COH) in the US banking industry; our preferred estimates do not support it. Public banks offer similar deposit rates in markets where they have common shareholders with rivals and in markets where they do not. Our preferred panel regressions of deposit rates on profit weights implied by the COH yield precise zeros. Estimated effects on deposit quantities also do not support the COH.

我们评估了美国银行业中的共同所有权假说（COH）；我们的首选估计结果并不支持该假说。上市银行在与其竞争对手存在共同股东的市场和不存在共同股东的市场中提供相似的存款利率。我们首选的将存款利率对COH所隐含的利润权重进行面板回归，得到了精确的零值。对存款数量的估计效应同样不支持COH。
