Healthcare utilization varies widely between regions. Yet, the causes of regional variation are still not well understood, and they can also differ between countries and institutional settings. We exploit patient migration to examine which share of regional variation in ambulatory care use in...

Does higher medical spending improve quality of care? We estimate the effect of changes in regulated reimbursement prices for hospitals on multiple dimensions of hospital quality, including mortality outcomes, surgical complications, process quality, and patient satisfaction. We exploit an...

This paper provides fi eld evidence on (a) how price framing aff ects consumers' decision to switch health insurance plans and (b) how the price elasticity of demand for health insurance can be influenced by policymakers through simple regulatory efforts. In 2009, in order to foster competition...

To equalize differences in health plan premiums due to differences in risk pools, the German legislature introduced a simple Risk Adjustment Scheme (RAS) based on age, gender and disability status in 1994. In addition, effective 1996, consumers gained the freedom to choose among hundreds of...

This paper empirically assesses the relative role of health plan prices, service quality and optional benefits in the decision to choose a health plan. We link representative German SOEP panel data from 2007 to 2010 to (i) health plan service quality indicators, (ii) measures of voluntary...

Large regional disparities in health and healthcare costs prevail in many countries, but our understanding of the underlying causes is still limited. This study shows for the case of the Netherlands that population sorting through internal migration can explain a substantial share, around 28%,...

Competing hospitals may not only use quality of service to attract patients but also their specialization profile. Applying a Hotelling-duopoly and interpreting respectively quality and specialization as vertical and horizontal differentiation, we analyze the optimal allocation in both...

Medical technological progress has been shown to be the main driver of health care costs. A key policy question is whether new treatment options are worth the additional costs. In this paper we assess the causal effect of percutaneous transluminal coronary angioplasty (PTCA), a major new heart...

This paper studies how stress affects the mortality risk. Using a flexible approach and allowing for timevarying treatment effects, I find no impact of stress on the short-run mortality risk but a substantially increase in the long-run. The effects are especially pronounced for men. I provide...

We present causal evidence from a controlled experiment on the effect of pay for performance on physicians' behavior and patients' health benefits. At a within-subject level, we introduce performance pay to complement either fee-for-service or capitation. Performance pay is granted if a health...
