A influência da informação sobre segurança na demanda por automóveis: o caso do Latin NCAP no Brasil
Keywords in Portuguese
Demanda por automóveis
Logit aninhado
NCAP
Abstract in Portuguese
O presente trabalho procura avaliar a relevância da informação sobre a segurança dos automóveis para os consumidores brasileiros estimando um modelo de demanda logit aninhado controlado pelas notas de zero a cinco estrelas obtidas nos crash tests do Latin NCAP, pesquisa até o momento única no Brasil. Os resultados indicam que a nota nos crash tests são relevantes para a utilidade média dos consumidores com os carros mais bem avaliados mostrando um nível de utilidade maior em relação aos veículos menos seguros. Resultados auxiliares apontam que não há diferença nos preços médios dos modelos avaliados pelo Latin NCAP com notas de uma a cinco estrelas sendo os modelos avaliados com zero estrelas os únicos a apresentarem preços estatisticamente diferentes e mais baratos. Outros resultados obtidos mostram que um aumento no número de automóveis testados de uma determinada montadora aumenta mais que proporcionalmente a probabilidade de um outro automóvel da mesma marca ser avaliado

Nested logit
Abstract in English
The present work aims to evaluate how important is the information about car safety for consumers in brazilian market estimating a nested logit demand model using the Latin NCAP's grades from zero to five stars as independent variables, yet this research is unique in Brazil. The results obtained show that Latin NCAP's grades show some relevance for the consumer's mean utiliy as the higher grades exibit higher mean utility levels related to the lowest grades. Auxiliary results show that there is no statistic diference among the car's prices evaluated with one to five stars in the crash tests as the automobiles evaluated with zero stars appear as being the cheapest of all. Others results show that an increase in the number of tested vehicles from a given manufacturer raises more than proportionally the probability of a car from this same brand to be tested
