ABSTRACT En este documento se presenta la estimación de la inflación subyacente en Colombia durante el período comprendido entre enero de 1983 y marzo del 2004, obtenida mediante un esquema de tendencias estocásticas comunes asociadas a un modelo vectorial de corrección de errores con restricciones de carácter estructural (SVEC). En el sistema de información, la inflación subyacente se relaciona de manera directa con el crecimiento de un agregado monetario amplio, el nivel del producto, los términos de intercambio y el crecimiento de los salarios nominales. La medida resultante de inflación subyacente corresponde a la estimación de largo plazo de la inflación que es obtenida mediante el modelo de tendencias estocásticas comunes. La inflación subyacente estimada posee las características deseadas en cuanto a varianza y está relacionada con el comportamiento de la inflación observada. Con el fin de probar las bondades de la metodología, se calculan dos series de pronósticos de la inflación y de la inflación subyacente, con sus respectivos intervalos de confianza, mediante técnicas de bootstrapping basadas en dos longitudes de muestreo que son seleccionadas de manera aleatoria.

    ABSTRACT: Using a common trends model, a forward-looking "core" inflation measure is estimated for the Euro area based on long-run relations among major macroeconomic variables, bearing the interpretation of long-run inflation forecast. The proposed measure may be particularly suitable for the "two-pillar" monetary policy strategy of the ECB which focuses on medium-term inflation prospects. Copyright 2002 by Taylor and Francis Group

    ABSTRACT: In this paper we describe how restricted vector autoregressions can be employed to examine the sources of macroeconomic fluctuations. We show how cointegration restrictions can be used to identify a VAR system with common stochastic trends subject to transitory and permanent changes in average growth, and how we may investigate the system's responses to permanent shocks, i.e. to innovations to the trends. Theoretical cointegration vectors are derived from a small open economy growth model for terms of trade, real GDP, real consumption. and real investments. Applying these methods to Swedish annual data (1875-1986) we find that permanent real (supply) shocks account for most of the fluctuations in GDP, even in the short run.

    ABSTRACT: Econometric modeling of linear dynamic systems is considered in the light of new reasons for general to simple modeling of the joint data density. To offset the resulting modeling burden due to large numbers of variables, equations, and parameters, the authors consider PcFiml 8 as a modeling tool. Graphics allow vast amounts of information to be appraised at a glance. The demand for M1 in the United Kingdom is modeled as a system using the approach described and establishes that inflation, the interest rate, and output interact closely but are weakly exogenous in the money demand equation.
