A espiral de antisseleção no mercado brasileiro de planos de saúde individuais

Abstract

The anti-selection in the health insurance market can be a perverse phenomenon and compro-mising the balance of the insurance portfolio. The possibility of growing this effect is associated with the measures to guarantee the renewal of the policy and to establish a cross subsidy between the types of risks. The objective is to evaluate possible effects of the introduction of popular healthcare insurance plans in the Brazilian individual health insurance market. The results did not suggest the presence of intergenerational subsidies. But if it would be introdu-ced products with more competitive relative prices than the current ones, the anti-selective movement of policyholders is such that it jeopardizes, without exception. Therefore, there is evidence of a clear spiral movement with deterioration of current portfolios.
