This expansion in intensive care has raised concerns over unwarranted intensive care admissions. In this study, we examine whether the greater supply of NICUs causally raises admission rates. Our event-study results show that an additional NICU opening in a county raises the share of newborns admitted to the NICU by 8%. The majority of new NICU admissions come from healthier newborns (2,500 grams and over) rather than very premature newborns (<1,500 grams). Admission for the smallest newborns (those under 1,500 grams) only increases in counties with limited NICU access. In these areas, greater NICU supply also reduces mortality, but only for very small newborns (<1,500 grams). Together, our findings suggest a tradeoff, where higher NICU supply reduces neonatal mortality for the most vulnerable infants while also raising admission for healthier newborns.</p>","PeriodicalId":50186,"journal":{"name":"Journal of Health Economics","volume":"100 ","pages":"102967"},"PeriodicalIF":3.4,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143034036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several policies have been introduced to improve traffic safety and their effects have been well documented, the role of transitory health shocks or situational factors at explaining variations in fatal traffic accidents has been understudied. Exploring daily variation in city-specific pollen counts, this study finds novel evidence that traffic fatalities increase on days in which the local pollen count is particularly high. We find that the effects are present in accidents involving private vehicles and occur most frequently on the weekends, suggesting potentially the missed opportunity to avoid these fatalities. We do not find similar effects for fleet vehicles. These findings remain robust to alternative specifications and alternative definitions of high pollen count. Taken together, this study finds evidence that a prevalent and transitory exogenous health-shock, namely pollen allergies, increases traffic fatalities. Given our lack of evidence of avoidance, these effects are not mechanical and are likely driven by cognitive impairments that arise as a result of seasonal allergies.</p>","PeriodicalId":50186,"journal":{"name":"Journal of Health Economics","volume":"99 ","pages":"102945"},"PeriodicalIF":3.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find, firstly, that, unlike in an adverse-selection-only market, in an environment where also moral hazard is important, removing insurers' selection incentives requires risk-adjustment payments that do not fully equalize costs among consumer types. Current practice of attempting to correct for all predictable cost differences among consumers is then misguided. Secondly, if the sponsor of the risk-adjustment system is not only concerned with eliminating selection distortions, but also wants to redistribute towards high-risk consumers, the required higher risk-adjustment payments will introduce selection distortions in high-risk consumers' contracts. This leads to excessive equilibrium provision of care for those suffering severe health shocks. Finally, insurer market power creates countervailing incentives, helping the risk adjuster to combat selection distortions but working against a risk-adjustment regulation that also cares about redistribution.</p>","PeriodicalId":50186,"journal":{"name":"Journal of Health Economics","volume":"99 ","pages":"102955"},"PeriodicalIF":3.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142824669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
