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...

The most recent financial crisis unveiled that liquidity risk is far more important and intricate than regulation have conceived. The shift from bank-based to market-based financial systems and from Deferred Net Systems to liquidity-demanding Real-Time Gross Settlement of payments explains some...

This document explores the predictive power of the yield curves in Latin America (Colombia, Mexico, Peru and Chile) taking into account the factors set by the specifications of Nelson & Siegel and Svensson. Several forecasting methodologies are contrasted: an autoregressive model, a vector...

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...

Colombia experienced a deep recession in 1999-2003. Growth slowed by 4.2%,and investment by 34.6%. Was the severity of the recession due to a ¯nan-cial accelerator mechanism µa la Bernanke, Gertler, and Gilchrist (1999)? Toanswer this question, this paper estimates a dynamic stochastic general...

Using Bayesian estimation techniques, we estimate a small open economyDSGE model with credit-market imperfections for the Colombian economy. Us-ing the estimated model we investigate what are the sources of business cycle°uctuations. We show that balance-sheet e®ects play an important role in...

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...
