This note develops simple conditions from which to determine the most concise VARMA representation of a given DSGE model. It is proven analytically that the Smets and Wouters (2007) model has exact VARMA (3,2) representation. In this model, the largest possible subset of structural parameters...

The Balassa-Samuelson (B-S) effect implies that highly productive countries have higher inflation and appreciating real exchange rates because of larger productivity growth differentials between tradable and nontradable sectors relative to advanced economies. The B-S effect might pose a threat...

The Global Integrated Monetary and Fiscal model (GIMF) is a multi-region DSGE model developed by the Economic Modeling Division of the IMF for policy and scenario analysis. This paper compares two versions of GIMF, GIMF with a conventional financial accelerator, where bank balance sheets do not...

This paper shows that a medium-scale DSGE model is able to explain a contemporaneous reduction of output and consumption during a disinflation policy, as it is in the empirical evidence. To this aim, we introduce Rotemberg (1982) adjustment costs and the limited asset market participation assumption

This paper develops and applies tools to assess multivariate aspects of Bayesian Dynamic Stochastic General Equilibrium (DSGE) model forecasts and their ability to predict comovements among key macroeconomic variables. The authors construct posterior predictive checks to evaluate the calibration...

This paper considers issues related to identification, inference and computation in linearized Dynamic Stochastic General Equilibrium (DSGE) models. We first provide a necessary and sufficient condition for the local identification of the structural parameters based on the (first and) second...

We study the workings of the factor analysis of high-dimensional data using artificial series generated from a large, multi-sector dynamic stochastic general equilibrium (DSGE) model. The objective is to use the DSGE model as a laboratory that allow us to shed some light on the practical...

This paper develops a DSGE model with housing, risky mortgages and endogenous default. Housing investment is subject to idiosyncratic risk and some mortgages are defaulted in equilibrium. An unanticipated increase in the standard deviation of housing investment produces a credit crunch where...

We show how to use a simple perturbation method to solve non-linear rational expectation models. Drawing from the applied mathematics literature we propose a method consisting of series expansions of the non-linear system around a known solution. The variables are represented in terms of their...
