We study which types of activities migrate to the shadow banking sector, why migration occurs in some sectors, and not others, and the quantitative importance of this migration. We explore this question in the $10 trillion US residential mortgage market, in which shadow banks account for more than half of new lending. Using micro data, we document a large degree of market segmentation in shadow bank penetration. They substitute for traditional—deposit taking—banks in easily securitized lending, but are limited from engaging in activities requiring on-balance sheet financing. Traditional banks adjust their financing and lending activities to balance sheet shocks, and behave more like shadow banks following negative shocks. Motivated by this evidence, we build a structural model. Banks and s...

Shadow bank market share in residential mortgage origination nearly doubled from 2007-2015, with particularly dramatic growth among online “fintech” lenders. We study how two forces, regulatory differences and technological advantages, contributed to this growth. Difference in difference tests exploiting geographical heterogeneity induced by four specific increases in regulatory burden–capital requirements, mortgage servicing rights, mortgage-related lawsuits, and the movement of supervision to Office of Comptroller and Currency following closure of the Office of Thrift Supervision--all reveal that traditional banks contracted in markets where they faced more regulatory constraints; shadow banks partially filled these gaps. Fintech lenders appear to offer a higher quality product and charg...
