In this paper, we provide a brief introduction to a new macroeconometric model of the Spanish economy named MEDEA (Modelo de EquilibrioDinámico de la Economía EspañolA). MEDEA is a dynamic stochastic general equilibrium (DSGE) model that aims to describe the main features of the Spanish...

In this paper, I review the literature on the formulation and estimation of dynamic stochastic general equilibrium (DSGE) models with a special emphasis on Bayesian methods. First, I discuss the evolution of DSGE models over the last couple of decades. Second, I explain why the profession has...

The output gap plays an important role in the assessment and conduct of monetary policy. Most of the current literature, however, relies on filtering procedures which use ad hoc smoothness arguments for identification. Furthermore, they are subject to end-of-sample problems and do not provide...

What drives the output gap? Contrary to standard agnostic statistical approaches, New Keynesian small open economy models allow decomposing the output gap into its shocks and confirm the conventional wisdom that most of the variation is due to foreign shocks. However, the risk premium shock also...

I propose to estimate structural impulse responses from macroeconomic time series by doing Bayesian inference on the Structural Vector Moving Average representation of the data. This approach has two advantages over Structural Vector Autoregressions. First, it imposes prior information directly...

This paper aims to identify the actual objectives of monetary authorities in Central and Eastern Europe (CEE) that promote an independent monetary policy. In this sense we consider the study of central banks (CBs) behavior in the Czech Republic, Poland, Romania and Hungary in establishing...

Existing methods for estimating nonlinear dynamic models are either highly computationally costly or rely on local approximations which often fail adequately to capture the nonlinear features of interest. I develop a new method, the discretization filter, for approximating the likelihood of...

We revisit the question whether U.S. fiscal policy in the pre-Volcker period was active or passive. To determine the policy stance, we estimate a DSGE model with monetary and fiscal policy interactions employing a sequential Monte Carlo algorithm (SMC) for posterior evaluation. In contrast to...
