Confrontando un modelo DSGE con los datos

Abstract

En este documento intentamos responder a una cuestión clave en la modelación macroeconómica ¿Qué tanto reproduce un modelo estocástico de equilibrio general los datos? Para responder esta pregunta usamos tres tipos de técnicas. Primero, comparamos los momentos estadísticos del modelo con los datos. Segundo, efectuamos una simulación de los ciclos. Tercero, comparamos las impulso-respuesta del modelo DSGE con las de un modelo SVAR. Adicionalmente, se estima el modelo usando métodos bayesianos. Tomando en cuenta datos de Estados Unidos durante 1950-2019, el modelo replica relativamente bien el comportamiento de los datos, aunque se observan ciertas diferencias en cuanto a las magnitudes.

In this document we try to answer a key question in macroeconomic modeling. How much does a stochastic model of general equilibrium reproduce the data? To answer this question we use three metrics. First, we compare the statistical moments of the model with the data. Second, we perform a simulation of the cycles. Third, we compare the impulse-response of the DSGE model with those of an SVAR model. Additionally, the model is estimated using Bayesian methods. Taking into account data from the United States, on a quarterly frequency (1950-2019), the model replicates the behavior of the data relatively well, although certain differences in magnitudes are observed.
