Competição em preços entre corretores de seguros de automóveis

Abstract

O preço final em um contrato de seguro de automóvel não depende apenas da seguradora, mas também do corretor de seguros. Sendo assim, o corretor é capaz de alterar o mecanismo desenhado inicialmente pela seguradora, distorcendo a alocação do risco entre as partes. Este artigo adapta o modelo de Stahl (1989) ao mercado de seguros de automóveis com o objetivo de explicar o comportamento estratégico dos corretores. O modelo prevê que o valor esperado da taxa de comissão escolhida pelo corretor seja função decrescente do prêmio requerido pela seguradora. Esta previsão foi testada e confirmada empiricamente, utilizando dados sobre vendas de apólices no mercado brasileiro. Na prática, este artigo contribui para que as seguradoras tenham maior controle sobre o prêmio final do seguro, o que torna a alocação do risco mais eficiente neste mercado.<br>The final price in a contract of automobile insurance depends not only the insurance company, but also the insurance agent. Thus, the agent is able to change the mechanism initially designed by the insurer, distorting the allocation of risk between the parts. This article adapts the model of Stahl (1989) to automobile insurance market in order to explain the agent's strategic behavior. The model predicts that the expected value of the commission rate chosen by the agent is a decreasing function of the premium required by the insurer. This prediction was tested and confirmed empirically using data on sales of policies in the Brazilian market. In practice, this article gives to the insurers more control over the final price, which drives to a more efficient allocation of risk in this market

Automobile insurance in Brazil: market concentration and demand

“…Regarding the factors that influence the demand for automobile, equity, and life insurance, França Carvalho and Afonso (2010) test the effects of criminality and macroeconomic variables over the demand for automobile insurance in São Paulo in the period from 2003 to 2007, finding that criminality has an effect, with a delay in the insurance demand decision. Ledo (2011) goes beyond the insurance provider market and shows how the strategic behavior of insurance brokers can distort the mechanisms designed by the insurance companies. For São Paulo, in the period from January of 2002 to July of 2004, he showed that the rate of commission expected by the broker is negatively related with the premium required by the insurer.…”
