Maravall and del Río (2001), analized the time aggregation properties of the Hodrick-Prescott (HP) filter, which decomposes a time series into trend and cycle, for the case of annual, quarterly, and monthly data, and showed that aggregation of the disaggregate component cannot be obtained as...

The sovereign debt crisis in the euro area has raised interest in early warning indicators, aimed at signalling the build-up of fiscal stress in advance and helping prevent crises by means of a timely counteraction of fiscal and macroeconomic policies. This paper presents possible improvements...

We develop a dynamic factor model to compute short term forecasts of the Spanish GDP growth in real time. With this model, we compute a business cycle index which works well as an indicator of the business cycle conditions in Spain. To examine its real time forecasting accuracy, we use real-time...

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...

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...

We present evidence about the loss of the so-called "plucking effect", that is, a high-growth phase of the cycle typically observed at the end of recessions. This result matches the belief, presented informally by different authors, that recession may have now permanent effects, or recession...

In a search and matching environment, this paper assesses a range of modeling setups against macro evidence for the monetary transmission mechanism in the euro area. In particular, we assess right-to-manage vs. efficient bargaining, flexible vs. sticky wages, interactions at the firm level...

We analyse the incidence of endogenous entry and firm TFP-heterogeneity on the response of aggregate inflation to exogenous shocks. We build up an otherwise standard DSGE model in which the number of firms is endogenously determined and firms differ in their steady state level of productivity....

We propose a Markov-switching dynamic factor model to construct an index of global business cycle conditions, for performing short-term forecasts of quarterly world GDP growth in real time and computing real-time business cycle probabilities. To overcome the real-time forecasting challenges, the...

Modern DSGE models are microfounded and have deep parameters that should be invariant to changes in economic policy, so in principle they are not subject to the Lucas critique. But the literature has already established that misspecification issues also cause parameter instability after policy...
