Business cycle properties under different monetary policy rules are examined in a variety of dynamic stochastic general equilibrium models (the real business cycle models, the nominal wage contract models with different length of contracts, and the monopolistic competition models with different...

The aim of this paper is twofold. First, I study how the proportion of fixed and variable-rate mortgages in an economy can affect the way shocks are propagated. Second, I analyze optimal implementable simple monetary policy rules and the welfare implications of this proportion. I develop and...

We analyze optimal monetary policy in a model with two distinct financial frictions. First, borrowing is subject to collateral constraints. Second, credit flows are intermediated by monopolistically competitive banks, thus giving rise to endogenous lending spreads. We show that, up to a second...

Recent treatments of the issue of a zero floor on nominal interest rates have been subject to some important methodological limitations. These include the assumption of perfect foresight or the introduction of the zero lower bound as an initial condition or a constraint on the variance of the...

The paper contains some implications for applied econometric research. Two important ones are, first, that invertible models, such as AR or VAR models, cannot in general be used to model seasonally adjusted or detrended data. The second one is that to look at the business cycle in detrended...

Hodrick-Prescott (HP) Filter of (most often, seasonally adjusted) quaterly series is analysed. Some of the criticism to the filter are adressed. It is seen that, while filtering strongly affects autocorrelations, it has little effect on crosscorrelations. It is argued that the criticism that HP...

This paper studies the relationship between Spanish real aggregate fluctuations and those of its Europe neighbors in the last decades. It studies the ability of alternative International Real Business Cycle models (based on Backus, Kehoe and Kydland (1994) with different degrees of international...

This paper studies the implications of cross-country housing market heterogeneity for a monetary union, also comparing the results with a flexible exchange rate and independent monetary policy setting. I develop a two-country new Keynesian general equilibrium model with housing and collateral...

In this monograph, first, we analyze in detail some of the major limitations of the standard procedure to estimate business cycles with the Hodrick-Prescott (HP) filter. By incorporating time series analysis techniques, it is seen how some intuitive and relatively simple modifications to the...
