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...

In this paper, we study the empirical relationship between credit funding sources and the financial vulnerability of the Colombian banking system. We propose a statistical model to measure and predict banking-fragility episodes associated with credit funding sources classified into retail...

As a natural extension to León and Vivas (2010) and León and Reveiz (2010) this paper briefly describes the Cholesky method for simulating Geometric Brownian Motion processes with long-term dependence, also referred as Fractional Geometric Brownian Motion (FBM). Results show that this method...

Este documento reporta los resultados de la estimación de una versión reciente del modelo P-estrella de Gerlach y Svensson (2003) para Colombia (1980: I - 2005: IV) y sus predicciones. El modelo está diseñado para explicar la brecha de inflación (tasa observada menos la meta) con base en...
