|September 2019||The Economic Consequences of Bankruptcy Reform|
with Tal Gross, Feng Liu, Matthew J. Notowidigdo, Jialan Wang: w26254
A more generous consumer bankruptcy system provides greater insurance against financial risks, but it may also raise the cost of credit to consumers. We study this trade-off using the 2005 Bankruptcy Abuse Prevention and Consumer Protection Act (BAPCPA), which raised the costs of filing for bankruptcy. We identify the effects of BAPCPA on borrowing costs by exploiting variation in the effects of the reform on bankruptcy risk across credit-score segments. Using a combination of administrative records, credit reports, and proprietary market-research data, we find that the reform reduced bankruptcy filings, and reduced the likelihood that an uninsured hospitalization received bankruptcy relief by 70 percent. BAPCPA led to a decrease in credit card interest rates, with an implied pass-through ...
|May 2016||The Economic Consequences of Hospital Admissions|
with Carlos Dobkin, Amy Finkelstein, Matthew J. Notowidigdo: w22288
We examine some economic impacts of hospital admissions using an event study approach in two datasets: survey data from the Health and Retirement Study, and hospital admissions data linked to consumer credit reports. We report estimates of the impact of hospital admissions on out-of-pocket medical spending, unpaid medical bills, bankruptcy, earnings, income (and its components), access to credit, and consumer borrowing. The results point to three primary conclusions: non-elderly adults with health insurance still face considerable exposure to uninsured earnings risk; a large share of the incremental risk exposure for uninsured non-elderly adults is borne by third parties who absorb their unpaid medical bills; the elderly face very little economic risk from adverse health shocks.

|June 2015||Beyond Statistics: The Economic Content of Risk Scores|
with Liran Einav, Amy Finkelstein, Paul Schrimpf: w21304
In recent years, the increased use of “big data” and statistical techniques to score potential transactions has transformed the operation of insurance and credit markets. In this paper, we observe that these widely-used scores are statistical objects that constitute a one-dimensional summary of a potentially much richer heterogeneity, some of which may be endogenous to the specific context in which they are applied. We demonstrate this point empirically using rich data from the Medicare Part D prescription drug insurance program. We show that the “risk scores,” which are designed to predict an individualʼs drug spending and are used by Medicare to customize reimbursement rates to private insurers, do not distinguish between two different sources of spending: underlying health, and responsi...
