This paper examines the impact of the composition of local banking markets on customer satisfaction. I measure customer satisfaction at the county level using complaint data filed with the Consumer Financial Protection Bureau (CFPB) from 2012-2017. I find that there are fewer customer complaints in counties where there is a larger presence of small banks, holding constant the level of bank competition. This effect holds for various complaint types, market types, market demographics, and alternative econometric specifications. Additionally, I provide a detailed description of the CFPB complaint data.
