Relação entre taxas de juros e mercados financeiros

Abstract

Usando a análise com wavelets poderá representar-se de um modo eficiente uma série temporal com uma dinâmica complexa. A chamada análise de wavelets, desenvolvida a partir da década de 1980, pelas suas capacidades de localização no plano tempo-frequência com uma resolução não constante, veio fornecer uma ferramenta alternativa à tradicional análise de Fourier. O uso das wavelets tem vindo a ser utilizado pelos economistas nos últimos anos, para a análise de dados económicos e financeiros, fazendo uso da chamada transformada discreta da wavelet. Com a introdução de novos conceitos, na década de 1990, acabaram por surgir generalizações da teoria das wavelets. Esses novos conceitos, tal como a transformada de wavelet contínua ou coerência da wavelet cruzada, permitem a análise das dependências tempo-frequência de duas séries. Neste trabalho pretende-se observar se existe relação entre taxas de juros e mercados financeiros, para isso, propôs-se a análise de wavelets com incidência no comportamento do índice Dow Jones Industrial Average e a taxa de juro Effective Federal Funds Rate. Recorreu-se para tal, aos espectros das ôndulas e de seguida, à coerência e à diferença de fase entre as duas séries.
