In\r\nour theoretical model, physicians are faced with a heterogeneous patient population, in which patients\r\nsystematically vary with regard to both their responsiveness to the provided quality of care and their\r\nstate of health. We test the behavioral predictions derived from this model in a controlled laboratory\r\nexperiment. In line with the model, we observe that competition significantly improves patient benefits\r\nas long as patients are able to respond to the quality provided. For those patients, who are not able\r\nto choose a physician, competition even decreases the patient benefit compared to a situation without\r\ncompetition. This decrease is in contrast to our theoretical prediction implying no change in benefits for\r\npassive patients. Deviations from patient-optimal treatment are highest for passive patients in need of\r\na low quantity of medical services. With repetition, both, the positive effects of competition for active\r\npatients as well as the negative effects of competition for passive patients become more pronounced. Our\r\nresults imply that competition can not only improve but also worsen patient outcome and that patients’\r\nresponsiveness to quality is decisive."}],"status":"public","_id":"44092","project":[{"name":"SFB 901: SFB 901","_id":"1"},{"_id":"2","name":"SFB 901 - A: SFB 901 - Project Area A"},{"name":"SFB 901 - A3: SFB 901 - Subproject A3","_id":"7"}],"department":[{"_id":"280"},{"_id":"475"}],"user_id":"37339","keyword":["physician competition","patient characteristics","heterogeneity in quality responses","fee-for-service","laboratory experiment"],"article_type":"original","language":[{"iso":"eng"}]},{"title":"Price Regulation, Quality Competition and Location Choice with Costly Relocation","date_created":"2023-04-20T17:12:18Z","author":[{"first_name":"Burkhard","last_name":"Hehenkamp","id":"37339","full_name":"Hehenkamp, Burkhard"},{"full_name":"Kaarbøe, Oddvar M.","last_name":"Kaarbøe","first_name":"Oddvar M."}],"date_updated":"2023-04-20T17:16:24Z","citation":{"apa":"Hehenkamp, B., &#38; Kaarbøe, O.

The model is relevant in markets such as public health care, education and schooling, or postal services. We find that, when the regulated price is low or intermediate, the entrant strategically locates towards the corner of the market to keep the incumbent at the low monopoly quality level. For a high price, the entrant locates at the corner of the market and both providers implement higher quality compared to a monopoly. In any case, the entrant implements higher quality than the incumbent provider. Social welfare is always higher in a duopoly if the cost of quality is low. For higher cost levels welfare is non-monotonic in the price and it can be optimal to the regulator not to use its entire budget. Therefore, the welfare effect of entry depends on the price and the size of the entry cost, and the regulator should condition the decision to allow entry on an assessment of the entry cost."}],"type":"report"},{"oa":"1","date_updated":"2023-07-07T11:23:08Z","volume":412,"author":[{"last_name":"Haake","full_name":"Haake, Claus-Jochen","id":"20801","first_name":"Claus-Jochen"},{"last_name":"Hehenkamp","full_name":"Hehenkamp, Burkhard","id":"37339","first_name":"Burkhard"},{"id":"83983","full_name":"Polevoy, Gleb","last_name":"Polevoy","first_name":"Gleb"}],"doi":"10.5281/zenodo.8068414","has_accepted_license":"1","place":"Paderborn","page":"21-44","intvolume":"       412","citation":{"ieee":"C.-J.

Two monopolistic manufacturers each produce a differentiated good. One sells it to both retailers, while the other only supplies a single retailer. Retailers compete in prices. Retail bundling is profitable when the goods are close substitutes. Only then is competition so intense that the retailer uses bundling to relax competition both within and across product markets, despite an aggravation of the double marginalization problem. Our asymmetric market structure arises endogenously for the case of close substitutes. In this case, bundling reduces social welfare.","lang":"eng"}],"user_id":"37339","department":[{"_id":"280"},{"_id":"475"}],"project":[{"_id":"1","name":"SFB 901: SFB 901"},{"name":"SFB 901 - A: SFB 901 - Project Area A","_id":"2"},{"_id":"7","name":"SFB 901 - A3: SFB 901 - Subproject A3"}],"_id":"44091","language":[{"iso":"eng"}],"keyword":["Retail bundling","upstream market power","double marginalization","product differentiation"]},{"date_created":"2021-05-20T09:58:43Z","publisher":"Conexio","title":"Projekt Art-D Grids: Nachhaltige und stabile Microgrids in Afrika - eine Plattform für Forschung und Lehre für die Entwicklung","quality_controlled":"1","year":"2021","language":[{"iso":"ger"}],"keyword":["Art-D","Afrika","Resilienz","Resilience","Grid stability","robustness","microgrids"],"ddc":["620"],"publication":"Tagungsband des 36.

The prices are regulated and providers compete in location and quality. We show that whereas opening a public hospital market typically raises quality, the private provider strategically locates towards the corner of the market to avoid costly quality competition. Social welfare depends on the size of the regulator's budget and on the altruism of the public provider. If the budget is large, high quality results and welfare is highest in a duopoly whenever entry is optimal. If the budget is small, quality levels in a duopoly mirror the quality level in a monopoly. It can be optimal for the regulator not to use the full budget.","lang":"eng"}],"publication":"Journal of Economic Behavior & Organization","language":[{"iso":"eng"}],"year":"2020","title":"Location Choice and Quality Competition in Mixed Hospital Markets","date_created":"2020-07-01T07:50:45Z"},{"title":"Evolutionary equilibrium in contests with stochastic participation: Entry, effort and overdissipation","doi":"10.1016/j.jebo.2019.06.011","date_updated":"2022-01-06T06:51:29Z","author":[{"first_name":"Yiquan","full_name":"Gu, Yiquan","last_name":"Gu"},{"first_name":"Burkhard","last_name":"Hehenkamp","full_name":"Hehenkamp, Burkhard","id":"37339"},{"first_name":"Wolfgang","full_name":"Leininger, Wolfgang","last_name":"Leininger"}],"date_created":"2019-09-06T09:28:46Z","year":"2019","citation":{"ama":"Gu Y, Hehenkamp B, Leininger W.

We show that there is ex-ante overdissipation under FPESS for sufficiently large participation probabilities, if, and only if, the impact function is convex. With costly endogenous entry, players enter the contest with a higher probability and exert more effort under FPESS than under NE. Importantly, under endogenous entry, overdissipation can occur for all (Tullock) contest success functions, in particular those with concave impact functions.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Journal of Economic Behavior & Organization"},{"article_type":"original","file_date_updated":"2018-11-02T15:39:01Z","project":[{"name":"SFB 901","_id":"1"},{"_id":"2","name":"SFB 901 - Project Area A"},{"name":"SFB 901 - Subproject A3","_id":"7"}],"_id":"1054","user_id":"477","department":[{"_id":"280"},{"_id":"475"}],"status":"public","type":"journal_article","doi":"10.1002/hec.3583","date_updated":"2022-01-06T06:50:43Z","author":[{"first_name":"Janet","full_name":"Brosig-Koch, Janet","last_name":"Brosig-Koch"},{"last_name":"Hehenkamp","id":"37339","full_name":"Hehenkamp, Burkhard","first_name":"Burkhard"},{"first_name":"Johanna","full_name":"Kokot, Johanna","last_name":"Kokot"}],"volume":26,"citation":{"ama":"Brosig-Koch J, Hehenkamp B, Kokot J.

Previous research has shown that, without competition, physicians deviate from patient‐optimal treatment under payment systems like capitation and fee‐for‐service. Although competition might reduce these distortions, physicians usually interact with each other repeatedly over time and only a fraction of patients switches providers at all. Both patterns might prevent competition to work in the desired direction. To analyze the behavioral effects of competition, we develop a theoretical benchmark that is then tested in a controlled laboratory experiment. Experimental conditions vary physician payment and patient characteristics. Real patients benefit from provision decisions made in the experiment. Our results reveal that, in line with the theoretical prediction, introducing competition can reduce overprovision and underprovision, respectively. The observed effects depend on patient characteristics and the payment system, though. Tacit collusion is observed and particularly pronounced with fee‐for‐service payment, but it appears to be less frequent than in related experimental research on price competition.

Different from most studies, we consider the unique symmetric entry equilibrium, which is in mixed strategies. We identify two effects of market transparency on welfare: a competition effect and a novel market-structure effect. We show, surprisingly, that for almost all demand functions the negative market-structure effect eventually dominates the positive competition effect as the market becomes increasingly transparent. Consumer-side market transparency can therefore be socially excessive even without collusion. The only exception among commonly used demand functions is the set of constant demand functions.
