We complement the empirical evidence on the sustainability of weight loss achieved through cash rewards and, for the first time, rigorously examine the potential of cash rewards to prevent weight cycling. In a three period randomized controlled trial, about 700 obese persons were first assigned...

Whereas in the United States, managed care (MC) plans have been part of the health care system for quite some time, they are still little known in European systems. In Germany in particular, policy makers would like to see a broad majority of the insured population shift to MC plans, hoping to...

Recent experimental studies analyze the behavior of physicians towards patients and nd that physicians care for their own pro t as well as patient bene t. In this paper, we extend the experimental analysis of the physician decision problem by adding a third party representing the health...

To test for ethnic discrimination in access to outpatient health care services, we carry out an email-correspondence study in Germany. We approach 3,224 physician offices in the 79 largest cities in Germany with fictitious appointment requests and randomized patients' characteristics. We find...

This paper analyzes whether moderate weight reduction improves subjective health perception in obese individuals. To cure possible endogeneity bias in the regression analysis, we use randomized monetary weight loss incentives as instrument for weight change. In contrast to related earlier work...

The classical Heckman (1976, 1979) selection correction estimator (heckit) is mis-specified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specifi cation problem, a full information maximum likelihood estimator and a...
