Interest rate volatility contributed to higher mortgage rates in 2022
The Federal Reserve aggressively tightened monetary policy in 2022, responding to high and persistent inflation. The resulting borrowing cost increase for households and firms was generally anticipated. However, fixed-rate mortgage interest rates were especially sensitive to the policy regime change.

Tests of ex ante versus ex post theories of collateral using private and public information
Collateral is a widely used, but not well understood, debt-contracting feature. Two broad strands of theoretical literature explain collateral as arising from the existence of either ex ante private information or ex post incentive problems between borrowers and lenders. However, the extant empirical literature has been unable to isolate each of these effects. This paper attempts to do so using a credit registry that is unique in that it allows the researcher to have access to some private information about borrower risk that is unobserved by the lender. The data also include public ...

Villains or Scapegoats? The Role of Subprime Borrowers in Driving the U.S. Housing Boom
An expansion in mortgage credit to subprime borrowers is widely believed to have been a principal driver of the 2002–2006 U.S. house price boom. By contrast, this paper documents a robust, negative correlation between the growth in the share of purchase mortgages to subprime borrowers and house price appreciation at the county-level during this time. Using two different instrumental variables approaches, we also establish causal evidence that house price appreciation lowered the share of purchase loans to subprime borrowers. Further analysis using micro-level credit bureau data shows that ...
Ability to Repay a Mortgage: Assessing the Relationship Between Default, Debt-to-Income
The Consumer Financial Protection Bureau has announced that it intends to change the definition of a “qualified mortgage.” Specifically, the CFPB proposes to reconsider the use of a borrower's debt-to-income ratio as a measure of the ability to repay a loan.

Quantitative Easing and Financial Risk Taking: Evidence from Agency Mortgage REITs
An emerging literature documents a link between central bank quantitative easing (QE) and financial institution credit risk-taking. This paper tests the complementary hypothesis that QE may also affect financial risk-taking. We study Agency MREITs – levered shadow banks that invest in guaranteed U.S. Agency mortgage-backed securities (MBS) principally funded with repo debt. We show that Agency MREIT growth is inversely related to the Federal Reserve’s Agency MBS purchases, reflecting investor portfolio rebalancing. We also find that these institutions increased leverage during the later ...
The Long Road to Housing Finance Reform: 'Are We There Yet?'
Over the past decade, broad-based legislative reforms for housing finance have proven elusive. However, reflecting lessons from the financial crisis, a political consensus has emerged on how Fannie Mae and Freddie Mac should operate.

Credit scoring and the availability, price, and risk of small business credit
We examine the economic effects of small business credit scoring (SBCS) and find that it is associated with expanded quantities, higher average prices, and greater risk levels for small business credits under $100,000. These findings are consistent with a net increase in lending to relatively risky "marginal borrowers" that would otherwise not receive credit, but pay relatively high prices when they are funded. We also find that: 1) bank-specific and industrywide learning curves are important; 2) SBCS effects differ for banks that adhere to "rules" versus "discretion" in using the ...

Estimating the effect of mortgage foreclosures on nearby property values: a critical review of the literature
In response to the wave of residential mortgage foreclosures in the past few years, federal, state and local government intervention programs have aimed to reduce the presumed social costs of foreclosures. Before the recent crisis, there was little economic research documenting foreclosure spillover effects. ; This article takes a critical look at the recent literature that seeks to estimate the negative effects of residential mortgage foreclosures. This review suggests that foreclosed properties sell at a discount, likely because such properties are in worse condition than surrounding ...

Villains or Scapegoats? The Role of Subprime Borrowers in Driving the U.S. Housing Boom
An expansion in mortgage credit to subprime borrowers is widely believed to have been a principal driver of the 2002?06 U.S. house price boom. Contrary to this belief, we show that the house price and subprime booms occurred in different places. Counties with the largest home price appreciation between 2002 and 2006 had the largest declines in the share of purchase mortgages to subprime borrowers. We also document that the expansion in speculative mortgage products and underwriting fraud was not concentrated among subprime borrowers.

The Effect of Large Investors on Asset Quality: Evidence from Subprime Mortgage Securities
The government-sponsored enterprises (GSEs) Fannie Mae and Freddie Mac?the dominant investors in subprime mortgage-backed securities before the 2008 crisis?substantively affected collateral composition in this market. Mortgages included in securities designed for the GSEs performed better than those backing other securities in the same deals, holding observable risk constant. Consistent with the transmission of private information, these effects are concentrated in low-documentation loans and for issuers that were highly dependent on the GSEs and were corporate affiliates of the mortgage ...
