The Supply Side of Household Finance
利用匹配的借款人和贷款人数据，研究发现银行在长期融资成本、存款基础或证券化渠道受到冲击时，更倾向于向借款人推荐浮动利率抵押贷款，且对金融素养较低的家庭影响更大。
Using matched borrower-lender data, we document strong nonprice supplier effects in mortgage contract choice. For given relative price of adjustable and fixed rate mortgages, households borrowing from banks hit by shocks to the cost of long term funding, or to the deposits base or to access to securitization are more likely to choose adjustable rate mortgages. Supply factors have larger effects on less-sophisticated households and at times of price inaction. A model in which banks affect borrowers’ choices through prices and distorted advice predicts these findings. We contrast the distorted advice interpretation of the evidence against the potential alternative nonprice channels.Received April 7, 2017; editorial decision October 21, 2018 by Editor Stijn Van Nieuwerburgh.
