"Monitoring Institutions in Health Care Markets: Experimental Evidence"

This paper investigates the impact of monitoring institutions on market outcomes in health care. Health care markets are characterized by asymmetric information. Physicians have an information advantage over patients with respect to the appropriate treatment for the patient and may exploit this informational advantage by over- and underprovision as well as by overcharging. We introduce two types of costly monitoring: endogenous and exogenous. Endogenous monitoring can be requested by patients, whereas exogenous monitoring is performed randomly by a third party. We present a toy model that enables us to derive hypotheses and to test them in a laboratory experiment. Our results show that introducing endogenous monitoring reduces the level of undertreatment and overcharging. Even under high monitoring costs, the threat of patient monitoring is sufficient to discipline physicians. Introducing exogenous monitoring also reduces undertreatment and overcharging when it is performed sufficiently frequently. Market efficiency increases when endogenous monitoring is introduced, as well as when exogenous monitoring is implemented with sufficient frequency. Our results therefore suggest that monitoring may be a feasible instrument to improve outcomes in health care markets.


Prof Werner Raub (Utrecht University)
"Trust in Social Environments:Complementary Designs (Including, but not Exclusively, Experiments) for Repeated Tests of Hypotheses"

The talk presents theory and empirical research on trust in social environments. These environments often include repeated interactions or networks of relations. Complementary research designs – surveys, vignette studies, and experiments – are employed for repeated tests of the same predictions on how such environments affect trust. Using complementary research designs can contribute to improving the link between theory and empirical research in social science and to establishing the robustness of empirical findings
