What’s the Catch? Suspicion of Bank Motives and Sluggish Refinancing
研究发现约50%的借款人因未再融资而损失数千美元，调查显示对银行动机的怀疑是阻碍再融资的关键行为因素，现场实验表明银行的优惠要约反而加深了怀疑。
Failing to refinance a mortgage can cost a borrower thousands of dollars. Based on administrative data from a large financial institution, we show that around 50% of borrowers leave thousands of dollars on the table by not refinancing. Survey data indicate that, among all the behavioral factors examined, only suspicion of banks’ motives is consistently related to the probability of accepting a refinancing offer. Finally, we report the results of three field experiments showing that enticing offers made by banks fail to increase participation and may even deepen suspicion. Our findings highlight the important role of trust in financial decisions. Received July 12, 2017; editorial decision April 3, 2018 by Editor Andrew Karolyi.
