Banks of a Feather: The Informational Advantage of Being Alike
研究发现银行更倾向于贷款给与自己相似的银行，利用德国信贷登记和监管数据表明，相似的投资组合有助于克服银行间市场的信息不对称，尤其对贷款组合不透明的借款人重要。
Abstract Banks lend more to banks that are similar to them. Using data from the German credit register and proprietary supervisory data on the quality of banks' loan portfolio, we show that a similar portfolio of the lending and borrowing bank helps to overcome information asymmetries in interbank markets. While interbank lenders generally do not adjust their lending to information on the counterparty's portfolio quality, banks with an exposure to similar industries and regions strongly react to this private information. Lending between similar banks is particularly important for borrowers with opaque loan portfolios, which do not obtain credit from dissimilar peers.
