Prior Fraud Exposure and Precautionary Credit Market Behavior
We study how past experiences with privacy shocks affect individuals’ likelihood to take precautionary behavior when faced with a new privacy shock in the context of credit markets. We focus on experiences with identity theft and data breaches, two kinds of privacy shocks that either directly lead to fraud or put an individual at an elevated risk of experiencing fraud. We show that immediately after the announcement of the 2017 Equifax data breach, individuals with either kind of prior fraud exposure were more likely to freeze their credit report and close credit card accounts than ...

Prior Fraud Exposure and Precautionary Credit Market Behavior
This paper studies how past experiences with privacy shocks affect individuals' take-up of precautionary behavior when faced with a new privacy shock in the context of credit markets. We focus on experiences with identity theft and data breaches, two kinds of privacy shocks that either directly lead to fraud or put an individual at an elevated risk of experiencing fraud. Using the announcement of the 2017 Equifax data breach, we show that individuals with either kind of prior fraud exposure were more likely to freeze their credit report and close credit card accounts than individuals with no ...

Credit Score Doctors
We study how the existence of cutoffs in credit scores affects the behavior of homebuyers. Borrowers are more likely to purchase houses after their credit scores cross over a cutoff to qualify them for a higher credit score bin. However, the credit accounts of these individuals (crossover group) are more likely to become delinquent within four years following home purchases than the accounts of those who had stayed in the same bin (non-crossover group). The effect is not only concentrated in subprime bins, but in other bins as well. It is neither limited to pre-crisis period nor curtailed by ...

Does Access to Free Pre-Kindergarten Increase Maternal Labor Supply?
In this paper, we evaluate the effects of free pre-kindergarten (pre-K) programs on the labor force participation (LFP) of mothers. We use variation in pre-K rules across all US states, including income eligibility requirements in some states. To estimate the causal effects of access to pre-K on labor supply, we exploit the panel aspect of the monthly Current Population Survey between 2002 and 2019. Specifically, we look at the change in labor market behavior of women when their child becomes age-eligible for pre-K, controlling for individual factors. We find that access to free pre-K ...

CECL Implementation and Model Risk in Uncertain Times: An Application to Consumer Finance
I examine the challenges of economic forecasting and model misspecification errors confronted by financial institutions implementing the novel current expected credit loss (CECL) allowance methodology and its impact on model risk and bias in CECL projections. We document the increased sensitivity to model and macroeconomic forecasting error of the CECL framework with respect to the incurred loss framework that it replaces. An empirical application illustrates how to leverage simple machine learning (ML) strategies and statistical principles in the design of a nimble and flexible CECL modeling ...

Climate Change and Consumer Finance: A Very Brief Literature Review
Extant research shows that climate change can impose significant costs on consumers’ wealth and finances. Both sea-level rise and flooding from hurricane events led to high price declines and thus wealth loss for homes in coastal areas or in disaster-struck areas, with effects lingering for a number of years in some cases. In terms of consumer finance, while the average consumer is not always significantly negatively affected by a disaster, the vulnerable groups (those with low credit scores and who are low income) can be severely affected, experiencing higher rates of delinquencies and ...

Retail Investors’ Contrarian Behavior Around News, Attention, and the Momentum Effect
Using a large panel of U.S. brokerage accounts trades and positions, we show that a large fraction of retail investors trade as contrarians after large earnings surprises, especially for loser stocks, and that such contrarian trading contributes to post earnings announcement drift (PEAD) and price momentum. Indeed, when we double-sort by momentum portfolios and retail trading flows, PEAD and momentum are only present in the top two quintiles of retail trading intensity. Finer sorts confirm the results, as do sorts by firm size and institutional ownership level. We show that the investors in ...

Consumption-Based Asset Pricing When Consumers Make Mistakes
I analyze the implications of allowing consumers to make mistakes on the risk-return relationships predicted by consumption-based asset pricing models. I allow for consumption mistakes using a model in which a portfolio manager selects investments on a consumer's behalf. The consumer has an arbitrary consumption policy that could reflect a wide range of mistakes. For power utility, expected returns do not generally depend on exposure to single-period consumption shocks, but robustly depend on exposure to both long-run consumption and expected return shocks. I empirically show that separately ...

The Smart Money is in Cash? Financial Literacy and Liquid Savings Among U.S. Families
Most financial advisors recommend storing three to six months of expenses in liquid assets in case of an emergency. Yet we estimate that more than half of U.S. families do not have at least three months of their non-discretionary expenses in liquid savings. We find that financial literacy is strongly predictive of having three months of liquid savings, controlling for income, income variability, and even parental resources. We also find that financial literacy predicts liquid savings across the income distribution. These results indicate that accumulation of an emergency fund is not ...
