Abstract
En esta investigación se utiliza un modelo SVAR extendido para estimar los
efectos de un incremento de la incertidumbre global sobre la economía peruana.
A diferencia de otros estudios que estiman los efectos los choques externos en
la economía peruana, en esta investigación me centro en el impacto de un
incremento de la volatilidad de estos choques externos. Las extensiones al
modelo SVAR incluyen: (i) permitir que la varianza varíe en el tiempo, a través
de una especificación de volatilidad estocástica; y (ii) permitir interacción entre
las variables endógenas y la volatilidad cambiante en el tiempo. Usando este
modelo, estimo que un incremento de una desviación estándar en la volatilidad
de los choques al PBI mundial se asocia con una caída del PBI de alrededor de
-3,3% relativo a su tendencia nueve trimestres luego del choque. Los
componentes de la demanda agregada parecen tener una respuesta negativa
más grande que los sectores productivos. En particular, el crecimiento de la
inversión cae alrededor de -7,7% relativo a su tendencia.
This study uses an extended SVAR model to estimate the effects of an increase in global uncertainty on the Peruvian economic activity. Unlike other studies that estimate the effects of external shocks on the Peruvian economy, in this paper I focus on the impact of an increase in the volatility of these foreign shocks. The extensions of the SVAR model include allowing for time-varying variance of structural shocks via a stochastic volatility specification and allowing interaction between the endogenous variables and the time-varying volatility. Using this model, I estimate that a one standard deviation increase in the volatility of the shocks to the world's GDP leads to a decline on Peruvian GDP of around -3,3% relative to its trend, nine quarters after the shock. Aggregate demand components appear to have a larger negative response than supply sectors. In particular, investment's growth falls around -7,7% relative to trend.
