The Credit Market Consequences of Job Displacement

The Review of Economics and Statistics 2018 100(3), 405-415 open access
This paper studies the role of job displacement in the household bankruptcy decision. Using an event-study methodology, I find that NLSY respondents are over three times more likely to file for bankruptcy immediately following a job loss. Using county-level data, I find similar magnitudes in the aggregate, with significant effects lasting two to three years. The results suggest that unemployment spells can have significant long-term consequences on households’ credit market outcomes.

Minimum payments and debt paydown in consumer credit cards

Journal of Financial Economics 2019 131(3), 528-548
Using a data set covering one quarter of the U.S. general-purpose credit card market, we document that 29% of accounts regularly make payments at or near the minimum payment. To explain the prevalence of low payment amounts, we exploit changes in issuers’ minimum payment formulas to quantify the explanatory power of two potential theories: liquidity constraints and anchoring. At least 22% of near-minimum payers (and 9% of all accounts) respond to the formula changes in a manner consistent with anchoring as opposed to liquidity constraints alone. Our results show that anchoring to a salient contractual term has a significant impact on household repayment decisions.

Moral Hazard during the Housing Boom: Evidence from Private Mortgage Insurance

Review of Financial Studies 2022 35(2), 771-813
Abstract We provide novel evidence of misaligned incentives fueling a portion of the 2000s mortgage boom. We document that private mortgage insurance (PMI) companies expanded insurance issuance on high-risk mortgages purchased by Fannie Mae and Freddie Mac at the tail end of the housing boom, without changing pricing and despite knowledge of heightened housing risk. The expansion of PMI facilitated an unprecedented increase in Fannie and Freddie’s risky purchases, extending the mortgage boom into 2007 and precipitating their collapse. We argue that this unraveling reflects a general moral hazard problem in insurance, coupled with misaligned incentives in the government-backed mortgage market.

Interest Rates and Equity Extraction During the Housing Boom

American Economic Review 2016 106(7), 1742-1774
Credit record panel data from 1999–2010 indicates that the likelihood of home equity extraction (borrowing, on average, about $40,000 against one's home) peaked in 2003 when mortgage rates reached historic lows. We estimate a 27 percent rise in extraction in response to a 100 basis point rate decline, and that house price growth amplifies this relationship. Differential responses to interest rates and home price appreciation by borrower age and credit score provide new evidence of financial frictions. Finally, equity extractions are associated with higher default risk, consistent with the use of borrowed funds for consumption or illiquid investment. (JEL D14, E43, E52, G12, R31)

Can Self-Control Explain Avoiding Free Money? Evidence from Interest-Free Student Loans

The Review of Economics and Statistics 2013 95(4), 1117-1129 open access
This paper uses insights from behavioral economics to explain a particularly surprising borrowing phenomenon: One in six undergraduate students offered interest-free loans turn them down. Models of impulse control predict that students may optimally reject subsidized loans to avoid excessive consumption during school. Using the National Postsecondary Student Aid Study (NPSAS), we investigate students' take-up decisions and identify a group of students for whom the loans create an especially tempting liquidity increase. Students who would receive the loan in cash are significantly more likely to turn it down, suggesting that consumers choose to limit their liquidity in economically meaningful situations.

Unsecured Credit Supply, Credit Cycles, and Regulation

Review of Financial Studies 2018 31(3), 1184-1217
This paper explores the dynamics of unsecured credit supply over the recent credit cycle and around the passage of the CARD Act. We examine a unique data set of over 200,000 credit card mail solicitations to a representative sample of households and introduce credit card offers as a direct, informative measure of supply of such credit. Contrasting personal credit card offer dynamics before and after the passage of the CARD Act with those of personal loans, auto loans, and corporate credit cards, we find that lenders reduced credit supply of personal credit cards to nonprime borrowers in response to the CARD Act. Our analysis highlights the importance of separately examining supply and demand responses to assess the unintended consequences of regulation.

Lender Screening and the Role of Securitization: Evidence from Prime and Subprime Mortgage Markets

Review of Financial Studies 2012 25(7), 2071-2108
[This article examines the link between mortgage securitization and lender screening during the boom and bust of the U.S. housing market. Using comprehensive data on both prime and subprime securitized and bank-held loans, we provide evidence that securitization affected lenders' screening decisions in the subprime market for low-documentation loans through two channels: the securitization rate and the time it takes to securitize a loan. The change in decision-making by subprime lenders occurs on dimensions that are unreported to investors. Examining the time-series evolution of the securitization market further reinforces these findings. We exploit heterogeneity across subprime and prime markets to illustrate that the potential for moral hazard may be reduced with greater collection of hard information and increased monitoring of lenders. Our results suggest that the policy debate regarding securitization and lenders' underwriting standards should separately evaluate the agency and non-agency markets, with special attention toward the extent of soft information in assets being securitized.]

Investment over the Business Cycle: Insights from College Major Choice

Journal of Labor Economics 2021 39(4), 1043-1082 open access
How does personal exposure to economic conditions affect individual human capital investment choices? Focusing on bachelor’s degree recipients, we find that cohorts exposed to higher unemployment rates during typical schooling years select majors that earn higher wages, have better employment prospects, and lead to work in a related field. Conditional on expected earnings, recessions also encourage women to enter male-dominated fields, and students of both genders pursue more difficult majors. We conclude that economic environments change how students select majors, and we find evidence that students who respond to the business cycle enjoy earnings typical of their new majors.
