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...

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...

Se estima una NAIRU que cambia en el tiempo de acuerdo con la composición dela fuerza laboral. Bajo este enfoque la NAIRU promedio para el período 1984-2005 es 11,9%. Además, dada la existencia de metas de inflación, estimamos unacurva de Phillips ampliada con una regla de formación de...

En este artículo se propone un método numérico para la calibración de un modelode equilibrio general dinámico y estocástico (DSGE). Esencialmente, éste consisteen utilizar un algoritmo híbrido de optimización, primero para encontrar un estadoestacionario del modelo, y luego para...

We estimate a non-parametrical Capital Asset Pricing Model (CAPM) and find strong evidence rejecting the classical linear CAPM. Furthermore, we find inconsistent linear betas for a series of stocks in the Colombian stock exchange (BVC), supporting the hypothesis of a better and consistent...

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...

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...
