This paper proposes a recursive procedure that characterizes the order of the pole and the coecients of the Laurent series representation of the inverse of a regular analytic matrix function. The algorithm consists in performing a finite sequence of rank factorizations of matrices of...

The present paper shows that there is a simple way to check whether a DSGE model can be represented by a finite order VAR. This consists in verifying that the eigenvalues of a certain matrix defined in Fernandez-Villaverde et al. (2007) are all equal to zero. Further we show that this condition...

The `local rank factorization' (lrf) of a regular matrix polynomial at an eigenvalue consists of a sequence of matrix rank factorizations of a certain function of its coecients; the lrf delivers the local Smith form and extended canonical systems of root functions that correspond to the...

This paper shows that the poor man's invertibility condition in Fernandez-Villaverde et al. (2007) is, in general, sufficient but not necessary for fundamentalness; that is, a violation of this condition does not necessarily imply the impossibility of recovering the structural shocks of a DSGE...

In this paper we analyze the yield difference between two on- and off-the-run similar notes to gauge the liquidity premium. We investigate this issue by relating such a differential to several liquidity indicators that we build and examine -to our knowledge for the first time- throughout the...

In this paper we model macroeconomic instability as the outcome of the dynamical interaction between debt accumulation and the “state of confidence” in a small open economy with a super-fixed exchange rate arrangement. Our analysis is set in a theoretical framework where balance-sheets...

In this paper we present an analysis of the OECD production process and consider the ICT as driver of growth. In doing so the production function approach adopted underlines the externalities exploited or not and, possibly, when the production process overpasses the countries capacities implied...

Non stationary panel models allowing for unobservable common trends have recently become very popular. However, standard methods, which are based on factor extraction or models augmented with cross-section averages, require large sample sizes, not always available in practice. In these cases we...

With this study we intend to define a methodology capable to deal with the task of evaluating and planning the interdependent dynamics of growth for some European countries together with their foreign partners. To that aim we employ a nonlinear differential equations system representing a...

In this paper we illustrate the potential use of an old/new methodology which combines the use of concentration curves in order to investigate the components that make up a regression coefficient. The illustration is based on examining gender differences in the effect of age on labor market...
