  2. World-wide trend • Health care expenditures are growing while financing based on Mandatory Health Insurance (MHI) cannot grow accordingly. • Many countries are considering the option to rely increasingly on Voluntary Health Insurance (VHI) schemes. • This trend causes widespread concerns regarding a potential loss of solidarity, in terms of access to insurance coverage.

  3. Solidarity • Solidarity = Cross-subsidization. • Risk-solidarity: from low-risks to high-risks. • Income-solidarity: from high-income groups to low-income groups.

  4. MHI • Competitive mandatory health insurance (MHI) guarantee some Income- & Risk-Solidarity via regulations, such as: • Compulsory enrollment for certain (categories of) individuals; • Risk-adjustment system; • Open enrollment; • Community-rated premiums (CRP).

  5. VHI • Voluntary (supplementary) health insurance markets are competitive and unregulated in most countries. • Unregulated competitive insurance markets cannot sustain implicit cross-subsidies because competition minimizes the predictable profits per contract (=Equivalence). • They tend to Risk-Rated Premiums (RRP).

  6. The Dutch case • In the Netherlands (2004), many benefits were transferred from MHI to VHI. • Currently, VHI providers self-regulate by adopting more or less community-rated premiums (CRP) which result in some Risk-Solidarity. • But in the long term, the transition from MHI to VHI implies a loss of Risk-Solidarity given that VHI providers will (CRP) RRP.

  7. Objective • Provide an empirical illustration of the consequences for Risk-solidarity of the transition from CRP to RRP in the VHI market; • Discuss the available alternatives to maintain a “socially acceptable” level of solidarity, if desired, in VHI markets.

  8. Method • Simulation of scenarios in which benefits covered by MHI are transferred to VHI; • Calculation of CRP and RRP (premium range) for each simulated benefit package; • Analysis of the implications for solidarity in the market for VHI.

  9. Data • Administrative data issued by the largest Sickness Fund in the Netherlands (AGIS, 2002); • N=1.5 million; • Analysis with 0.5 million individuals with identical package.

  13. Conclusions • If benefits MHI  VHI coverage  RRP more probable in the long-run; • CRP  RRP in VHI markets implies a substantial increase in the premium range for the complete VHI benefit package; • This implies a reduction of Risk-solidarity, of which Policy makers should be aware when transferring benefits from MHI to VHI; • If Society considers this reduction too high, the preferred alternative to maintain an “acceptable level of Risk-solidarity” in a VHI is by implementing a system of “explicit premium subsidies” (van de Ven et al. , JHE, 2000).

  14. Issues for discussion • If Risk-Solidarity is required, should the coverage be Mandatory or Voluntary? • After the change from CRP to RRP, is VHI still a tool for cream-skimming?
