No. of bitstreams: 1 tesecovo.pdf: 385739 bytes, checksum: 253e4c0b5c2b22775f64b6e31b4c0cea (MD5) Previous issue date: 2009-06-01 / Este trabalho demonstra como podemos usar opções sobre o Índice de Taxa Média de Depósitos Interfinanceiros de Um Dia (IDI) para extrair a função densidade de probabilidade (FDP) para os próximos passos do Comitê de Política Monetária (COPOM). Como a decisão do COPOM tem uma natureza discreta, podemos estimar a FDP usando Mínimo Quadrados Ordinários (MQO). Esta técnica permite incluir restrições sobre as probabilidades estimadas. As probabilidades calculadas usando opções sobre IDI são então comparadas com as probabilidades encontradas usando o Futuro de DI e as probabilidades calculadas através de pesquisas. / This paper demonstrates how options on the One-day Brazilian Interfinancial Deposits Index (IDI) can be used to recover the implied probability density function (PDF) for futures Monetary Policy Committee (COPOM) outcomes. The discrete nature of the choices made by the COPOM allows recovering the PDF using ordinary least squares (OLS) estimation. This method also allows the imposition of restrictions on the recovered probabilities. Recovered probabilities using options on IDI are then compared to the probabilities obtained using the futures on DI and the probabilities recovered by surveys.
