El canal del crédito bancario, que amplifica los efectos del canal tradicional de la política monetaria, hace énfasis en la estructura y las fricciones del mercado financiero como determinantes del gasto agregado. Este artículo analiza y verifica la existencia del canal del crédito bancario en Colombia estimando un modelo propuesto por Michael Gibson en 19971997, quien utiliza regresiones de umbral para determinar el impacto de la política monetaria sobre la demanda agregada. Los resultados obtenidos no permiten descartar la existencia de este mecanismo de transmisión en Colombia durante el periodo analizado, aunque éste parece operar solo a través de la política monetaria contraccionista.
Palabras clave: política monetaria, mecanismos de transmisión, canal de crédito bancario, modelos de umbral. Clasificación JEL: C12, C52, E44, E52, G11.
Abstract:
The Bank Credit Channel, which amplifies the effects of the traditional channel of monetary policy, emphasizes on the structure and frictions of financial markets as determinants of aggregate spending. This paper aims at analyze and verify the existence of the bank credit channel in Colombia estimating a model proposed by Gibson (1997) which uses threshold regressions as a way to determine the impact of monetary policy on aggregate demand. Results do not allow dismissing the existence of this transmission mechanism in Colombia during the analyzed period, although it seems to operate only through contractionary monetary policy.

Résumé:
Le canal du crédit bancaire amplifie les effets du canal traditionnel de la politique monétaire et met l.accent sur la structure et sur les frictions du marché financier, lesquels constituent les éléments qui déterminent de la dépense agrégée. L.objectif de cet article est d.analyser et de vérifier l.existence du canal du crédit bancaire en Colombie en estimant le modèle proposé par Michael Gibson en 1997, lequel utilise des régressions à seuil pour déterminer l.impact de la politique monétaire sur la demande agrégée. Les résultats obtenus ne permettent pas d.écarter l.existence d.un mécanisme de transmission pendant la période analysée, malgré le fait qu.il ne paraisse agir qu.à travers une politique monétaire restrictive.
