En este documento se analiza la exposición al riesgo de mercado del portafolio de deuda pública de las diferentes entidades del sistema ?nanciero Colombiano desde dos perspectivas. En la primera, se emplea el enfoque tradicional en donde se calcula el valor en riesgo no condicional (a otras...

In this paper we check the relationschip between the yields of the Colombian bonds traded in the (secondary) internal market and the yields of the sovereign global securities for the sample period 1999-2001. The hypothesis we maintain is that, under the assumption of capital mobility, it should...

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...

A maximum likelihood method for estimating the power-law exponent verifies that the positive and negative tails of the Colombian stock market index (IGBC) and the Colombian peso exchange rate (TRM) approximate a scale-free distribution, whereas none of the heavy tails of a local sovereign...

En este trabajo se estima una tasa natural de desempleo para Colombia en el período 1984-2006. Siguiendo el modelo de negociación de salarios de Blanchard (1991), se emplea un filtro de Kalman, para estimar un sistema de ecuaciones para la tasa natural de desempleo, el desajuste del mercado...

The long-run component of the Colombian unemployment rate is estimated for the last twenty years. According to the results, the main determinants of the permanent component of the unemployment rate are the real hourly wage, the non-wage labor costs and the rate of capital accumulation. Given the...

En este documento se propone utilizar la metodología de perfiles coincidentes propuesta por Martínez (2010), con el fin de determinar si un conjunto de indicadores obtenidos de encuestas de opinión y otras fuentes son coincidentes o líderes de los indicadores económicos observables y, que...

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...

Since correlation may be interpreted as a measure of the influence across time-series, it may be conveniently mapped into a distance and into a weighted adjacency matrix. Based on such matrix, network theory has attempted to filter out the noise in correlation matrices by extracting the dominant...

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...
