The purpose of the present study is to explore the specific contributions of variousnominal and real rigidities in monetary DGE models in a systematic way and ina common framework. I will concentrate on a quite simple model setup in orderto find out the important transmission mechanisms at work....

The theoretical relation between exchange rate and prices has been a difficult proposition to find supporting evidence despite many studies of developed economies using standard research methods. The exchange rate to price relation appears to hold in the long run only, a result consistent with...

In most instances, the dynamic response of monetary and other policies to shocks is infrequent and lumpy. The same holds for the microeconomic response of some of the most important economic variables, such as investment, labor demand, and prices. We show that the standard practice of estimating...

Diese Dissertation besteht aus drei Aufsätzen, welche die Effekte von Geld- und Fiskalpolitiken für die Makroökonomie untersuchen. Der erste Aufsatz analysiert, wie das Verhalten der Inflation nach z.B. geldpolitischen Veränderungen erklärt werden kann. Mankiw und Reis (2002) propagieren...

A number of researchers have recently argued that the new-Keynesian Phillips curve matches the empirical behavior of inflation well when the labor income share is used as a driving variable, but fits poorly when deterministically detrended output is used. The theoretical motivation for these...

El presente trabajo resume la literatura existente relativa a los modelos de ajuste de los precios nominales, centrándose en los modelos de comportamiento óptimo o casi óptimo. El documento abarca tres clases principales de mecanismos: 1) modelos que suponen un coste fijo (menu cost) al...
