Estimando a Aversão ao Risco, a Taxa de Desconto Intertemporal, e a Substutibilidade Intertemporal do Consumo no Brasil usando Três tipos de Função Utilidade (Versão Preliminar)

  • Issler, João Victor
  • Piqueira, Natália Scotto

Este trabalho estima, usando o método generalizado dos momentos e dados brasileiros, os parâmetros estruturais do modelo CCAPM (consumption capital asset pricing model) a partir de três classes de funções utilidade distintas: função utilidade potência (CES/CRRA), utilidade com hábito externo, e aversão ao desapontamento (Kreps-Porteus). Estes parâmetros estruturais estão associados à aversão ao risco, à elasticidade de substituição intertemporal no consumo e a taxa de desconto intertemporal da utilidade futura, o foco central desse artigo. Os resultados aqui obtidos são analisados e comparados com resultados anteriores para dados brasileiros e americanos.
