Price Elasticities and Social Health Insurance Choice in Germany: A Dynamic Panel Data Approach (original) (raw)

Price elasticities in the German Statutory Health Insurance market before and after the health care reform of 2009

Health Policy, 2015

This paper investigates the change in price elasticity of health insurance choice in Germany after a reform of health insurance contributions. Using a comprehensive data set of all sickness funds between 2004 and 2013, price elasticities are calculated both before and after the reform for the entire market. The general price elasticity is found to be increased more than 4-fold from −0.81 prior to the reform to −3.53 after the reform. By introducing a new kind of health insurance contribution the reform seemingly increased the price elasticity of insured individuals to a more appropriate level under the given market parameters. However, further unintended consequences of the new contribution scheme were massive losses of market share for the more expensive sickness funds and therefore an undivided focus on pricing as the primary competitive element to the detriment of quality.

Consumer price sensitivity in Dutch health insurance

International Journal of Health Care Finance and Economics, 2008

Aim To estimate the price sensitivity of consumer choice of health insurance firm. Method Using paneldata of the flows of insured between pairs of Dutch sickness funds during the period 1993-2002, we estimate the sensitivity of these flows to differences in insurance premium. Results The price elasticity of residual demand for health insurance was low during the period 1993-2002, confirming earlier findings based on annual changes in market share. We find small but significant elasticities for basic insurance but insignificant elasticities for supplementary insurance. Young enrollees are more price sensitive than older enrollees. Conclusion Competition was weak in the market for health insurance during the period under study. For the market-based reforms that are currently under way, this implies that measures to promote competition in the health insurance industry may be needed.

Statutory health insurance competition in Europe: A four-country comparison

Health Policy, 2013

This paper explores the goals and implementation of reforms introducing choice of and competition among insurers providing statutory health coverage in Belgium, Germany, the Netherlands and Switzerland. In theory, health insurance competition can enhance efficiency in health care administration and delivery only if people have free choice of insurer (consumer mobility), if insurers do not have incentives to select risks, and if insurers are able to influence health service quality and costs. In practice, reforms in the four countries have not always prioritised efficiency and implementation has varied. Differences in policy goals explain some but not all of the differences in implementation. Despite significant investment in risk adjustment, incentives for risk selection remain and consumer mobility is not evenly distributed across the population. Better risk adjustment might make it easier for older and less healthy people to change insurer. Policy makers could also do more to prevent insurers from linking the sale of statutory and voluntary health insurance, particularly where take-up of voluntary coverage is widespread. Collective negotiation between insurers and providers in Belgium, Germany and Switzerland curbs insurers' ability to influence health care quality and costs. Nevertheless, while insurers in the Netherlands have good access to efficiency-enhancing tools, data and capacity constraints and resistance from stakeholders limit the extent to which tools are used. The experience of these countries offers an important lesson to other countries: it is not straightforward to put in place the conditions under which health insurance competition can enhance efficiency. Policy makers should not, therefore, underestimate the challenges involved.

In Absolute or Relative Terms? How Framing Prices Affects the Consumer Price Sensitivity of Health Plan Choice

SSRN Electronic Journal, 2000

This series presents research findings based either directly on data from the German Socio-Economic Panel Study (SOEP) or using SOEP data as part of an internationally comparable data set (e.g. CNEF, ECHP, LIS, LWS, CHER/PACO). SOEP is a truly multidisciplinary household panel study covering a wide range of social and behavioral sciences: economics, sociology, psychology, survey methodology, econometrics and applied statistics, educational science, political science, public health, behavioral genetics, demography, geography, and sport science.

Choice of public or private health insurance: learning from the experience of Germany and the Netherlands

Journal of European Social Policy, 2006

Several European countries have considered introducing choice of public or private health insurance - usually by allowing people to ‘opt out’ of the statutory scheme - under the assumption that enhancing consumer choice and stimulating competition between insurers will be beneficial. This article examines the impact of opting out on equity and efficiency in European health systems. Focusing on Germany

Can insurer competition improve health system performance? Evidence from Western Europe

This article considers the potential for insurer competition to improve health system performance by strengthening purchasing. Economic theory suggests that insurer competition will enhance efficiency if: (1) people have free choice of insurer, (2) competition is based on price and quality rather than risk selection and (3) insurers have tools to influence health care costs and quality. The article assesses the extent to which these assumptions hold in Belgium, Germany, the Netherlands and Switzerland. It finds that health insurance market reforms in these countries have had mixed results in fulfilling these assumptions. In spite of significant investment in risk equalisation, incentives for risk selection remain. Consumer mobility is lower among older and chronically ill people, possibly due to close interaction between statutory and voluntary coverage. Although insurers in some countries increasingly have tools to enhance value, they may not always use them. The analysis suggests that the instrumental value of insurer competition rests on multiple assumptions that can only be upheld through frequently complex interventions often requiring elusive data. Making it work therefore requires action on several fronts, particularly to ensure incentives are aligned across the health system, and awareness of the political nature of some barriers to success.

On Market Share Drivers in the Swiss Mandatory Health Insurance Sector

Risks

In the mandatory health insurance market in Switzerland, a range of insurers offer policies that differ in characteristics like premium and service level while benefits are the same and regulated by law. In this paper, we give an overview of the market and analyse the relationship between insurers’ characteristics and the evolution of their market shares. Indeed, in view of substantial differences between the players, the risk that policyholders change their provider is important. We develop a linear model with two-sided lognormally distributed errors and use publicly available data on the Swiss mandatory health insurance market for the years from 2002 to 2015. Thereby we identify and quantify the main drivers for the policyholders’ switching behavior that reflect in changes in market shares. The results suggest that market share changes are particularly linked to the difference between an insurer’s premium and the overall market premium. In addition, the difference to the previous ...
