We investigate co-movements in inflation dynamics within and across euro area regions and find it important for monetary policy to monitor regional inflation dynamics to enhance the understanding of aggregate inflation. We employ a model where regional inflation dynamics are explained by common...

In this paper we investigate the sources of the important shifts in the volatility of U.S. macroeconomic variables in the postwar period. To this end, we propose the estimation of DSGE models allowing for time variation in the volatility of the structural innovations. We apply our estimation...

We examine linear-quadratic (LQ) approximation of stochastic dynamic optimization problems in macroeconomics (and elsewhere), in particular in policy analysis using Dynamic Stochastic General Equilibrium (DSGE) models. We first define the problem that is solved by a social planner, given that...

This paper addresses three issues on the conduct of monetary policy in open economies on the basis of a two-country model with Calvo-type sticky prices. Is the isomorphism of the optimal policy problems between closed and open economies robust to whether the foreign country is buffeted by...

In the literature, there are not satisfactory methods for measuring and presenting the performance of confidence regions. In this paper, techniques for measuring effectiveness of confidence regions and for the graphical display of simulation evidence concerning the coverage and effectiveness of...

In this paper an AK growth model is fully analyzed under the time to build assumption. The existence and uniqueness of the (real) balanced growth path and the oscillatory convergence of detrended capital while detrended consumption is constant over time is proved. Moreover the role of...

Apart from the risk premium of equity over bonds, volatility of asset prices and trading volumes are two aspects of the already developed general equilibrium asset pricing theory that fail to show any resemblance with real data. The assumption of agent homogeneity has been relaxed in a number of...

We reconsider the derivation of the traditional capital asset pricing model (CAPM) in the discrete time setting for a portfolio of one riskless asset and many risky assets. In contrast to the standard setting, it is assumed that agents are heterogeneous in their conditional means and covariances...

This paper analyzes if each European country presents business cycles that are similar enough to validate what some authors call the European cycle. Contrary to the majority of papers on business cycles, we concentrate on the appearance of the cycle, not on the synchronization. We provide a...

This paper develops a general equilibrium model with Dixit-Stiglitz preferences, monopolistic competition and rational inattention on the side of both households and firms. We show how to solve a general equilibrium model with rational inattention. We use the model to study how rational...
