中文摘要
我们利用患有晚期癌症的医生患者所属的医学专业领域，研究知识与关系网络在治疗选择和患者生存中的作用；通过将患者与医生及入院时期进行可比匹配，以控制不可观测的医生质量。与非医生患者相比，医生患者接受手术、放疗或检查的可能性更低，接受靶向治疗的可能性更高，药物支出更多，生存率更高，且共同保险支出更少。知识机制发挥着关键作用，因为关系网络效应能够解释部分但非全部模式。对于医学知识较少的医生患者而言，拥有关系网络等同于减少所需的医学知识。
Abstract
We use the medical specialties of physician-patients with advanced cancer to study the role of knowledge versus networks in treatment choices and patient survival by matching comparable patients with doctors and admission periods to control unobserved doctor quality. Physician-patients are less likely to have surgery, radiation, or checkups and more likely to receive targeted therapy, spend more on drugs, enjoy a higher survival rate, and spend less on coinsurance than nonphysician-patients. Knowledge mechanisms play a crucial role because the network effect explains some, but not all, patterns. For less informed physician-patients, possessing a network is equivalent to reducing medical knowledge.
