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...

This paper examines the relationship between mortgage default decisions andrelevant observable variables under the light of a random utility model. The focusof the study is the Colombian mortgage market between 1997 and 2004 using twoseparate data sets that are matched using simulation...

This paper presents two versions of a spatial competition model forthe banking sector. The first version, describes a framework that fol-lows closely Salop´s spatial competition model. This version is modi-fied in the second part by introducing the loan market and default riskprobabilities for...

Este documento estudia una parte relevante del mecanismo de transmisión de la política monetaria asociado con el crédito bancario. Con tal objeto se estima un modelo VARXGARCH multivariado para establecer la relación, en frecuencia diaria, entre dos tasas de interés de corto plazo, la CDT y...

Este trabajo evalúa si las transformaciones de potencia (Box-Cox y en particular logarítmica) de series de tiempo mejoran la precisión de los pronósticos de modelos ARIMA ajustados a variables económicas de Colombia en dos periodos diferentes: 1980-1995 y 2002-2012. Se compara la habilidad...

This paper investigates whether transforming the Consumer Price Index with a class of power transformations lead to an improvement of inflation forecasting accuracy. We use one of the prototypical models to forecast short run inflation which is known as the univariate time series ARIMA . This...

Bajo el supuesto de que una serie de retornos es independiente e idénticamente distribuida (IID), la dimensión temporal del riesgo es irrelevante. De esta forma, la volatilidad calculada sobre un intervalo de tiempo (e.g. mensual) puede ser estimada a partir de la calculada sobre otro...

En este documento estimamos el grado de transmisión de corto y largo plazo sobre lainflación de los bienes importados de un choque a la tasa de devaluación nominal enpresencia de asimetrías. Utilizamos una ecuación estándar de pass-through para modeloscon competencia imperfecta, datos...

This paper contributes an estimation framework to measure both technological and linkage externalities from foreign direct investment (FDI). Empirical research dealt mainly with intra-industry spillovers from FDI with restrictive treatment of inter-industry effects until recently. However, as...

This article analyzes identification problems that may arise while linearizing and solving DSGE models. A criterion is proposed to determine whether or not a set of parameters is partially identifiable, in the sense of Canova and Sala (2009), based on the computation of a basis for the null...
