This study presents an alternative way of estimating credit transition matrices using a hazard function model. The model is useful both for testing the validity of the Markovian assumption, frequently made in credit rating applications, and also for estimating transition matrices conditioning on...

This paper estimates transition matrices for the ratings on financial insti-tutions, using an unusually informative data set. We show that the process of rating migration exhibits significant non-Markovian behavior, in the sense that the transition intensities are affected by macroeconomic and...

En este documento se caracteriza el endeudamiento del sector corporativo privado con el sistema financiero durante el período 1998-2005, y se hallan los determinantes de la probabilidad de que una empresa colombiana incumpla con el pago las obligaciones que ha contraído con este. A través de...

En este artículo se explora empíricamente el vínculo entre la volatilidad y el desalineamiento de la tasa de cambio real (TCR) con la actividad de las empresas en Colombia durante el período 2000-2011. Se analiza su efecto sobre las ventas externas, la productividad, la inversión y las...

In a dynamic, stochastic, general equilibrium model,we explore the optimal response of the inhabitans of a closed economy to an inefficient ad hoc financial system that in its intermediation duty looses a fraction of aggregate savings which otherwise would become aggregate investment. The...

Este documento analiza la relación existente entre la deuda externa pública y la inversión privada para Colombia entre 1994 y 2007, a partir del modelo de series de tiempo no lineales TAR. La estimación del modelo se realizó a través de los métodos MCMC y el enfoque bayesiano. Los...

Este trabajo pretende determinar qué conjunto de rigideces nominales y reales se debe incluir en un modelo DSGE para replicar la dinámica de las variables agregadas de la economía colombiana. Con este fin, se estiman varios modelos DSGE con distintas combinaciones de rigideces nominales y...

Derivatives are contingent claims that complete financial markets. Their use allow agents and firms to ameliorate the impact over con- sumption, production and investment given a change in relative prices induced by an active monetary policy. In this sense, derivatives gene- rate in some cases a...

This paper provides empirical evidence of the impact of fiscal decentralization on Colombia’s public basic education. Based on the social and economic data available for 1,003 municipalities and 13,670 public schools, for the last decade, we confirmed that decentralization has had a positive...

This paper analyzes the link between young people's sense (locus) of control over their lives and their investments in education. We find that young people with a more internal locus of control have a higher probability of finishing secondary school and, conditional on completion, meeting the...
