Abstract

We leverage consumer credit panel data to examine the impact of hospital consolidation on individual medical debt. Using a stacked event study research design, we find that exposure to a hospital merger increases the probability that individuals have medical debt one year later by 1.9 percent. Despite this, we find no early evidence that mergers increase average medical debt flow. The two results together suggest that some individuals saw medical debt decline post-merger, enough to balance the amounts incurred by the newly indebted

Abstract

This paper uses multiple sources of data to study the effect of the entry of WellNow urgent care centers (UCC) in New York State on individual health outcomes and health care access. Using a staggered difference-in-differences approach, we show that the opening of a new urgent care center leads to better self-assessed health for individuals living in that particular county. We also find evidence of a decreased strain on the local healthcare system, as the opening of a nearby WellNow facility leads to shorter hospital waiting times and increased likelihood that individuals have a timely routine checkup

Abstract

This study presents new evidence on the potential detrimental effects of hospital closures. We examine how hospital closures affect the likelihood of incurring medical debt. Hospital closures can increase market concentration by removing a competitor from the market. Closures can also have negative spillover effects on the local economy and affect the population’s ability to pay their bills. We combine 2011-2020 consumer credit bureau data with information on hospital closures from 2014-2018 to assess the relationship between closures and medical debt. Using a stacked event study approach, we find that a closure that reduces hospital supply in a Hospital Referral Region (HRR) by 10 percent is associated with a 4 percent increase in the share of consumers with medical debt, with larger effects in HRRs that are urban and have higher rates of poverty. Moreover, we find that a hospital closure is associated with about a 6-8 percent increase in hospital market concentration. These findings suggest that the primary mechanism through which hospital closures affect medical debt is by reducing hospital competition in local markets.
