Obesity and overweight are linked to diseases that cost society a significant amount of resources. While behavior modification can reduce the problem, instigating such lifestyle changes is an uneasy task. One potential way to reduce the problem is through the use of financial incentives. In this...

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...

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

Due to regional competition and patient migration, the efficiency of healthcare provision at the regional level is subject to spatial dependence. We address this issue by applying a spatial autoregressive model to longitudinal data from Germany at the district (`Kreis') level. The empirical...

Obesity may not only be linked to undesirable health outcomes but also to limitations in sexual life. The present paper aims to assess whether there is a relationship between weight change and sexual activity in obese individuals. To address the endogeneity of weight loss that is likely to...

The question of whether two drugs - namely alcohol and tobacco - are used as complements or substitutes is of crucial interest if side-effects of anti-smoking policies are considered. Numerous papers have empirically addressed this issue by estimating demand systems for alcohol and tobacco and...

This paper uses individual level data to analyze the effect of changes in the compulsory benefit package of the German statutory health insurance scheme on the demand for private supplementary insurance. In particular, we aim at measuring the effect of excluding dentures from the benefit package...

In contrast to West-Germany, illicit drugs were virtually absent in East-Germany until 1990. Yet, after the collapse of the former GDR, East-Germany was expected to encounter a sharp increase in the prevalence of substance abuse. By analyzing individual data, we find that East-Germany largely...

The inefficiency of health care provision presents a major health policy concern in Germany. In order to address the issue of efficiency comprehensively - i.e. at the level of the entire system of health care provision rather than individual service providers - empirical analyses are often based...

Over the last years, public smoking bans have been introduced in most European countries. Unlike elsewhere, in Germany such bans were introduced at state level at different points in time, which provides important intra-country regional variation that can be exploited to identify the effects of...
