As the share of supplementary health insurance (SI) in health care finance is likely to grow, SI may become an increasingly attractive tool for riskselection in basic health insurance (BI). In this paper, we develop a conceptual framework to assess the probability that insurers will use SI for favourable riskselection in BI. We apply our framework to five countries in which risk-selection via SI is feasible: Belgium, Germany, Israel, the Netherlands, and Switzerland. For each country, we review the available evidence of SI being used as selection device. We find that the probability that SI is and will be used for risk-selection substantially varies across countries. Finally, we discuss several strategies for policy makers to reduce the chance that SI will be used for risk-selection in BI markets.

A competitive market for individual health insurance tends to risk-adjusted premiums. Premium rate restrictions are often considered a tool to increase access to coverage for high-risk individuals in such a market. However, such regulation induces selection which may have several adverse effects. As an alternative approach we consider risk-adjusted premium subsidies. Empirical results of simulated premium models and subsidy formulae are presented. It is shown that sufficiently adjusted subsidies eliminate the need for premium rate restrictions and consequently avoid their adverse effects. Therefore, the subsidy approach is the preferred strategy to increase access to coverage for high-risk individuals. q
Who Took out Additional Supplementary Health Insurance? A dynamic Analysis of Adverse-Selection
I n s t i t u t e f o r R e s e a r c h a n d I n f o r m a t i o n i n H e a l t h E c o n o m i c s no 150-January 2010 According to economic theory, individuals choose their insurance cover levels in virtue of anticipated health expenditures. Thus, they partially reveal their health risks. Yet, on the French health insurance market this hypothesis, known as 'adverse-selection', has only been tested on the supplementary health insurance purchase decision. However, the supplementary health insurance market is extremely heterogeneous, at least in the same way as beneficiaries' health risk levels. Between July 1st 2003 and December 31st 2006, a mutual insurance fund for state employees (Mutuelle générale de l'équipement et des territoires) offered existing holders of its supplementary cover ('MGET basic') an additional health coverage ('MGET+'). This particular context, where individuals covered from the same supplementary health insurance decide to pu...
Risk equalisation in voluntary health insurance markets: A three country comparison
Health Policy, 2010
The paper summarises the conclusions for health policy from the experience of three countries who have introduced risk equalisation subsidies, in their voluntary health insurance (VHI) markets. The countries chosen are Australia, Ireland and South Africa. All of these countries have developed VHI markets and have progressed towards introducing risk equalisation. The objective of such subsidies is primarily to make VHI affordable while encouraging efficiency in health care production.
Social Health Insurance: A Quantitative Exploration
SSRN Electronic Journal, 2016
We quantitatively explore the welfare benets of health insurance over the lifecycle in a dynamic general equilibrium model with health risk and a health care sector. We consider three distinct approaches to designing a health insurance system: (i) a mixed private and public health insurance system similar to the US system, (ii) private health insurance (PHI), and (iii) universal public health insurance (UPHI). Our results indicate that the introduction of the US system into an economy without any health insurance results in large welfare gains, but does not produce the best welfare outcome. The PHI system with some government regulation on premiums is viable and produces welfare gains comparable to the welfare gains generated by the US system. The UPHI system with a high enough coinsurance rate produces better overall welfare outcomes than the other two systems. There exists an optional coinsurance rate that maximizes the welfare benets of the UPHI system. A structural reform that replaces the US system with the UPHI systemi.e., Medicare for allis welfare improving, but would face political headwinds due to opposing welfare eects across income groups.
Public Health Insurance with Monopolistically Competitive Providers and Optional Spot Sales
The B.E. Journal of Economic Analysis & Policy
We study the implications of extending public-insurance coverage over differentiated medical products of the same therapeutic group to market outcomes. The public insurer can set the reimbursement level for medical providers and the copayment for the insured for medical care provided under the policy coverage, but cannot directly control providers’ spot sales (outside of insurance) price. In this setup, the price offered by the public insurer to medical providers must maintain their reservation profit from selling on the spot market directly to consumers. We show that the public insurer can manipulate this reservation profit by setting the copayment rate, and thereby promote market welfare while increasing consumers’ surplus due to lower medical prices and lower market entry. The results survive generalizations including moral hazard and incomplete insurance coverage.

This paper constructs a dynamic model of health insurance to evaluate the short-and long run effects of policies that prevent firms from conditioning wages on health conditions of their workers, and that prevent health insurance companies from charging individuals with adverse health conditions higher insurance premia. Our study is motivated by recent US legislation that has tightened regulations on wage discrimination against workers with poorer health status (Americans with Disability Act of 2009, ADA, and ADA Amendments Act of 2008, ADAAA) and that will prohibit health insurance companies from charging different premiums for workers of different health status starting in 2014 (Patient Protection and Affordable Care Act, PPACA). In the model, a trade-off arises between the static gains from better insurance against poor health induced by these policies and their adverse dynamic incentive effects on household efforts to lead a healthy life. Using household panel data from the PSID we estimate and calibrate the model and then use it to evaluate the static and dynamic consequences of no-wage discrimination and no-prior conditions laws for the evolution of the cross-sectional health and consumption distribution of a cohort of households, as well as ex-ante lifetime utility of a typical member of this cohort. In our quantitative analysis we find that although a combination of both policies is effective in providing full consumption insurance period by period, it is suboptimal to introduce both policies jointly since such policy innovation induces a more rapid deterioration of the cohort health distribution over time. This is due to the fact that combination of both laws severely undermines the incentives to lead healthier lives. The resulting negative effects on health outcomes in society more than offset the static gains from better consumption insurance so that expected discounted lifetime utility is lower under both policies, relative to only implementing wage nondiscrimination legislation.
Subscribing to Supplemental Health Insurance in France: A Dynamic Analysis of Adverse Selection
2010
Adverse selection, which is well described in the theoretical literature on insurance, remains relatively difficult to study empirically. The traditional approach, which focuses on the binary decision of “covered” or “not”, potentially misses the main effects because heterogeneity may be very high among the insured. In the French context, which is characterized by universal but incomplete public health insurance (PHI), we study the determinants of the decision to subscribe to supplemental health insurance (SHI) in addition to complementary health insurance (CHI). This work permits to analyze health insurance demand at the margin. Using a panelized dataset, we study the effects of both individual state of health, which is measured by age and previous individual health spending, and timing on the decision to subscribe. One striking result is the changing role of health risk over time, illustrating that adverse selection occurs immediately after the introduction of SHI. After the initi...
