The changing behaviour of the term structure of post-war US

Using U.S. interest rate data covering the period 1950:1-1992:7, this paper tests the rational expectations model of the term structure of interest rates. We show evidence that the rational expectations model of the term structure is supported by the data during the seventies and a period lasting from the mid-eighties to the end of the sample. However, during the …fties, sixties and a period that covers most of the Volcker’s office term (from September 1979 to April 1986) the term structure model is rejected by the data. Moreover, wefind evidence of regime changes in the short-term rate process and the term structure of interest rates. These regime switches roughly coincide with changes in the Federal Reserve chairman. The switches in monetary policy taking place when the chairmanship of the Federal Reserve changes therefore seem to play an important role in characterizing the term structure of interest rates.

Fachada de chapa perforada: análisis de su comportamiento acústico

[ES]Este proyecto tiene como objetivo servir de punto de partida al estudio del comportamiento acústico de las chapas perforadas como solución para el revestimiento de fachadas. Para ello se presentan dos posibles modelos de fachada analizados a través del software SoundFlow que determina su coeficiente de absorción. Con el fin de encontrar la solución más adecuada nos centraremos en las siguientes variables: separación de la chapa a la pared (d), diámetro del agujero de las chapas (Ø), y porcentaje de área perforada de la chapa o porosidad (p). Previamente se estudiarán las principales fuentes de contaminación acústica y su espectro de ruido para determinar la frecuencia en la que deben centrarse nuestros esfuerzos por aumentar el coeficiente de absorción.
