Typically, when forecasting inflation rates, there are a variety of individual models and a combination of several of these models. We implement a Bayesian shrinkage combination methodology to include information that is not captured by the individual models using expert forecasts as prior...

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...

An application of Bayesian Model Averaging, BMA, is implemented to construct combined forecasts for the colombian inflation for the short and medium run. A model selection algorithm is applied over a set of linear models with a large dataset of potencial predictors using marginal as well as...

This document presents how to estimate and implement a structural VAR-X model under long run and impact identification restrictions. Estimation by bayesian and maximum likelihood methods is presented. Applications of the structural VAR-X for impulse response functions to structural shocks,...

Este documento analiza la relación existente entre la deuda externa pública y la inversión privada para Colombia entre 1994 y 2007, a partir del modelo de series de tiempo no lineales TAR. La estimación del modelo se realizó a través de los métodos MCMC y el enfoque bayesiano. Los...

Este documento combina estimaciones de ocho metodologías de la brecha del producto colombiano para el período comprendido entre el primer trimestre de 1994 y el tercer trimestre de 2012. A partir de modelos VAR que incluyen las diferentes brechas y la inflación se construyen las densidades...

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...

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...
