Estimates show that physician-patients are less likely to use surgery or radiation, more likely to use targeted drug therapy, spend less on checkups, and enjoy higher long-term survival while paying less on coinsurance than nonphysician-patients. Restricting data to less informed physician-patients, we find that those with stronger professional ties receive less surgical/radiation therapy and have higher survival, though only for 0.5 years. We show that relational and informational advantages appear in healthcare agency problems.","PeriodicalId":341305,"journal":{"name":"InfoSciRN: Health Informatics (Topic)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125044811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
