Abstract

Resumen: En este artículo se pretende identificar el canal de transmisión de los choques de prima de riesgo en las diferentes variables macroeconómicas. Por tanto, se formula un modelo DSGE para una economía pequena y abierta, que considera el comportamiento de los hogares, las decisiones de inversión de parte de las empresas, la función de reacción del banco central y la dinámica de las diferentes variables externas, tales como la variación de los activos externos netos del país y el comercio exterior. El modelo se calibra con datos de la economía colombiana del periodo 2005-2017. En los resultados de la simulación se identifica la persistencia del shock de prima de riesgo en las variables endógenas que componen al modelo, y en especial se observan efectos sobresalientes del choque sobre el tipo de cambio, la tasa de interés y la inflación. Se concluye que el tamano de la elasticidad de la prima de riesgo al endeudamiento externo domina la fuerza con la que inciden los shocks en la economía. Abstract: This paper aims to identify the transmission channel of risk premium shocks in different macroeconomic variables. Therefore, a DSGE model for a small and open economy is formulated, which considers the behavior of households, investment decisions by companies, the reaction function of the central bank and the dynamics of the different external variables, such such as the variation of the country’s net foreign assets and foreign trade. The model is calibrated with data from the Colombian economy of the 2005-2017 period. In the simulation results, the persistence of the risk premium shock in the endogenous variables that make up the model is identified, and in particular, outstanding effects of the shock on the exchange rate, the interest rate and inflation are observed. It is concluded that the size of the elasticity of the risk premium to external indebtedness dominates the force with which the shocks affect the economy. Résumé: Cet article vise a identifier le canal de transmission des chocs de primes de risque dans différentes variables macroéconomiques. Pour ce faire, un modele DSGE est formulé pour une petite économie ouverte, prenant en compte le comportement des ménages, les décisions d’investissement des entreprises, la fonction de réaction de la banque centrale et la dynamique des différentes variables externes, telles que la variation des actifs extérieurs nets du pays et le commerce extérieur. Le modele est ensuite calibré avec les données de l’économie colombienne pour la période 2005-2017. Les résultats de la simulation montrent la persistance du choc de prime de risque dans les variables endogenes du modele. En particulier, nous montrons les effets remarquables du choc sur le taux de change, sur le taux d’intéret et sur l’inflation. Nous concluons que l’ampleur de l’élasticité de la prime de risque a l’endettement extérieur domine la force avec laquelle les chocs touchent l’économie.
