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...

One of the main trends of modern macroeconomic analysis is the development of dynamic stochastic general equilibrium models with a wide range of nominal and real rigidities and estimation of these models with the Bayesian technique. The article studies the application of this approach for the...

The severe repercussions of the latest financial crisis highlighted the crucial role of the financial sector in the propagation of economic and financial shocks. In this paper we analyse the role of financial market frictions in business cycle fluctuations and in the transmission of monetary...

The article presents a dynamic stochastic general equilibrium (DSGE) model of a small open economy. It is based on the New Open Economy Macroeconomics (NOEM) concept and derived from microeconomic foundations. Behavior of representative households and firms contains rigidities. Structure of...

This paper investigates the role of the RBC (Real Business Cycle) model with investment-specific technology shocks in explaining business cycle fluctuations in Brazil. I consider the role of transitory and permanent components of neutral and investment-specific technology shocks. I fit the model...

In this paper I estimate a New Keynesian Model with sticky prices for the Romanian economy for the period 1991-2002, using quarterly data. The estimation was made in Dynare using the Bayesian approach. The degree of the price stickiness is moderate. The model makes good predictions in terms of...

We estimate small open economy models with involuntary unemployment using Australian data from 1993 to 2007, focusing on hiring costs and real wage rigidity. We find a strong preference for models with hiring costs, which account for 0.97% of GDP. The data favour models with real over nominal...

We estimate the output gap that is consistent with a fully specified DSGE model. Given the structural parameters estimated using Bayesian methods, we estimate the output gap that is defined as a deviation of output from its flexible-price equilibrium. Our output gap illustrates the U.S. business...
