Übertragbare Altersrückstellungen in der privaten Krankenversicherung
AbstractEven in a capital funded health insurance system, competition between insurance companies is restricted. This is due to the fact that the insured who contribute to the capital fund are not allowed to transfer part of the capital fund if they change the insurer. This article deals with an alternative institutional arrangement, in which each person is assigned an individual portion of the capital fund that is transferred when the insurer is changed. It is asserted that an insurance company will systematically transfer reduced individual capital funds in order to avoid a loss of clients. In a competitive market, this is not a rational behaviour. The correct capital provision for each insured person is the present value of expected reimbursements of health expenditures minus the present value of expected premiums. Market competition will force the insurer to transfer an amount which is close to the necessary individual capital provision. This is the basis for a reaction on price signals by the insured and therefore for competition on the market of health insurance companies.
