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...

Colombian monthly data covering the period from 1995:01 to 2002:11 and ECM, fixed and time-varying parameters and Kalman filter techniques are used in this paper to quantify the exchange rate pass-through effects on import prices within a sample of manufactured imports. Also, whether the foreign...

This work analyzes the relationship between real interest rates and commodity prices. According to Frankel’s hypothesis (1986-2006): "low real interest rates lead to high real commodity prices". However, some empirical evidence suggests that commodity prices can predict monetary policy. In...

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 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....

Este documento realiza una descripción de las medidas de dependencia con sus principales ventajas y desventajas y presenta a la cópula como una estructura flexible que permite caracterizar diferentes tipos de dependencia. Adicionalmente, introduce el uso de la cópula en la medición de riesgo...

En este trabajo se analizan algunos aspectos de la regulación relacionada con el manejo del riesgo de mercado establecida por la Superintendencia Financiera de Colombia, donde se propone el valor en riesgo (VaR) como la medida para cuantificar este tipo de riesgo. No obstante, esta regulación...

En este documento se describen en detalle diversas metodologías que permiten calcular dos medidas utilizadas para cuantificar el riesgo de mercado asociado a un activo financiero: el valor en riesgo, VaR y el Expected Shortfall, ES. Los métodos analizados se dividen en dos grupos. En el primer...
