Experts are physicians and are assumed to differ in their cost of treating a small problem. We investigate the effects of this heterogeneity on the physicians’ level of fraud and on the patients’ search for second opinions. We find that introducing a fraction of more efficient low-cost physicians always increases social welfare, but in some cases only because of the raised physicians’ surplus. When the low-cost physicians’ cost advantage is small, imposing a share of low-cost physicians does not change the equilibrium fraud level. When the cost advantage is large, however, different changes in the fraud level occur depending on the share of generated low-cost physicians, the search rate and the initial level of fraud.","lang":"eng"}],"ddc":["330"],"user_id":"477","intvolume":"       118","place":"Paderborn University","keyword":["credence goods","treatment efficiency","heterogeneous experts","overcharging"],"title":"Credence Goods Markets with Heterogeneous Experts","author":[{"first_name":"Joachim Maria Josef","id":"53445","last_name":"Heinzel","full_name":"Heinzel, Joachim Maria Josef"}],"_id":"7630","language":[{"iso":"eng"}],"series_title":"CIE Working Paper Series","type":"report","project":[{"name":"SFB 901","_id":"1"},{"_id":"2","name":"SFB 901 - Project Area A"},{"name":"SFB 901 - Subproject A3","_id":"7"}],"status":"public","report_number":"2019-01","file_date_updated":"2019-02-12T08:21:37Z","department":[{"_id":"280"},{"_id":"475"}],"file":[{"file_name":"WP118.pdf","date_updated":"2019-02-12T08:21:37Z","creator":"jheinzel","access_level":"closed","file_size":286367,"content_type":"application/pdf","file_id":"7631","date_created":"2019-02-12T08:21:37Z","relation":"main_file","success":1}],"volume":118,"year":"2019","publisher":"CIE Working Paper Series"}
