Three methodologies of estimation of models with many predictors are implemented to forecast Colombian inflation. Two factor models, based on principal components, and partial least squares, as well as a Bayesian regression, known as Ridge regression are estimated. The methodologies are compared...

Este documento caracteriza los efectos dinámicos de los choques en el gasto y los ingresos del gobierno sobre la actividad económica en Colombia, durante el periodo 1980:1 - 2004:1. Esto mediante un VAR estructural mixto. El SVAR se estima utilizando el procedimiento de Blanchard y Perotti...

This paper contains the results of a non parametric multi-step ahead forecast for the monthly Colombian inflation, using Mean conditional Kernel estimation over inflation changes, with no inclusion of exogenous variables. The results are compared with those from an ARIMA and a nonlinear STAR....

Structural VAR and Structural VEC models were estimated for Chile and Colombia, aiming at identifying fiscal policy shocks in both countries between 1990 and 2005. The impulse responses obtained allow the calculation of a pesofor- peso ($/$) effect on output of a shock to public spending and to...

This article analyzes identification problems that may arise while linearizing and solving DSGE models. A criterion is proposed to determine whether or not a set of parameters is partially identifiable, in the sense of Canova and Sala (2009), based on the computation of a basis for the null...

Este documento evalúa el grado de transmisión de corto y largo plazo sobre la inflación de los bienes importados de un choque a la depreciación del peso colombiano cuando se controla por el ciclo económico. Encontramos que la transmisión es mayor cuando la perturbación ocurre en un...

The study of the asymmetric behavior of macroeconomic variables over the business cycles phases has had a long tradition in economics. In this work we find evidence in favor of the hypothesis of having a Star-type nonlinear asymmetric behavoir of the economy activity, over the last two decades,...

En este documento se da un breve resumen teórico de índices de precios, como también se describe las diferencias en la composición del IPC e IPP colombianos. Mediante técnicas econométricas se establecieron relaciones de largo plazo entre componentes de los dos indicadores, y se realizaron...
