”The Labor Market Effects of Credit Market Information”Review of Financial Studies, June 2018, 31(6), 2005-2037Editor’s Choice, Michael J. Brennan Best Paper Award 2019, Coauthors: Marieke Bos and Emily Breza.  Abstract

We exploit a natural experiment to provide one of the first measurements of the causal effect of negative credit information on employment and earnings. We estimate that one additional year of negative credit information reduces employment by 3 percentage points and wage earnings by $1,000. In comparison, the decrease in credit is only one-fourth as large. Negative credit information also causes an increase in self-employment and a decrease in mobility. Further evidence suggests this cost of default is inefficiently borne by those most creditworthy among previous defaulters.

”Impulsive Consumption and Financial Wellbeing: Evidence from an Increase in the Availability of Alcohol”, NBER Working Paper No. w23211, Coauthor: Itzhak Ben-David.  Fourth Round RFS  Abstract

Increased availability of alcohol might harm individuals if they have time-inconsistent preferences and consume more than planned before. We study this idea by examining the credit behavior of low-income households around the expansion of the opening hours of retail liquor stores during a nationwide experiment in Sweden. Consistent with store closures serve as commitment devices, expanded operating hours led to higher alcohol consumption and greater consumer credit demand, default, and negative consequences in the labor market. Our calculation shows that the effects of alcohol consumption on indebtedness could amount to 3.2 times the expenditure on alcohol.

“Bad Times, Good Credit”, Swedish House of Finance Research Paper No 15-05 Coauthors Bo Becker and Kasper Roszbach Second Round JMBC  Abstract

 Banks’ limited knowledge about borrowers’ creditworthiness constitutes an important friction in credit markets. Is this friction deeper in recessions, thereby contributing to cyclical swings in credit, or is the depth of the friction reduced, as bad times reveal information about firm quality? We test these alternative hypotheses using internal ratings data from a large Swedish cross-border bank and credit scores from a credit bureau. The ability to classify corporate borrowers by credit quality is greater during bad times and worse during good times Soft and hard information measures both display countercyclical patterns. Our results suggest that information frictions in corporate credit markets are intrinsically counter-cyclical and not due to cyclical variation in monitoring effort.

”Financial Distress and Suicide over the Lifecycle for Individuals with ADHD: A Population Study”, Coauthors: Theodore P. Beauchaine and Itzhak Ben-David. Submitted September 2019  Abstract

Attention-deficit/hyperactivity disorder (ADHD) exerts lifelong functional impairment, including difficulty maintaining employment, poor credit, and suicide risk. To date, however, most studies have assessed highly-selected samples, often via self-reports. Using mental health data collected from the full Swedish population (N=11.44 million) between 2002-2015 and a random sample of credit bureau data (N=189,267), we provide the first study of financial and suicide outcomes among adults with ADHD. Adjusting for education and income, those with ADHD start adulthood with normal credit demand. However, their default rates grow exponentially into middle age, resulting in diminished access to credit despite high demand. Those with ADHD who suffer marked financial distress show a fourfold higher suicide rate than others with the disorder. Prescription medication use is unassociated with improved financial behaviors.

”Scarcity and Consumers’ Credit Choice”, Swedish House of Finance Research Paper No. 16-19, 2016, Coauthors: Chloe Le Coq and Peter van Santen. Submitted June 2019 Abstract

This paper documents that high-educated borrowers choose lower loan to value ratios when their budget constraints are exogenously tighter. In contrast, low-educated borrowers do not respond to temporary elevated levels of scarcity. This lack of response translates into a significantly higher probability to default and an 11.6 percent increase in borrowing cost. We show that a difference in access to liquidity and/or buffer stocks cannot explain our results. Instead a framework where the awareness of self-control problems is positively correlated with education explains why high-educated, but not low-educated, consumers choose a lower LTV as a commitment device. Our findings highlight that increased levels of scarcity risk reinforcing the conditions of poverty.
