This paper studies the mechanism of adverse selection in the credit market using a sample of mortgage applications that are approved by lenders but rejected by applicants. We find that a low-risk applicant is more likely to reject a loan offer, except when the offer is made by an informed lender. Using jumbo mortgage and loan acceptance rate data to proxy for the information advantage, we find that lenders with a lower likelihood of being rejected are indeed better informed than others.

Banking competition may enhance or hinder the financing of small and medium-sized enterprises. Using a survey on the financing of such enterprises in China, combined with detailed bank branch information, we investigate how concentration in local banking market affects the availability of credit. We find that lower market concentration alleviates financing constraints. The widespread presence of joint-stock banks has a larger effect on alleviating these constraints, than the presence of city commercial banks, while the presence of state-owned banks has a smaller effect.
