Time changing effects of external shocks on macroeconomic fluctuations in Peru: empirical application using regime-switching VAR models with stochastic volatility
(Pontificia Universidad Católica del Perú. Departamento de Economía, 2022-03)
This article quantifies and analyzes the evolving impact of external shocks on Peru’s macroeconomic fluctuations in 1994Q1-2019Q4. For this purpose, we use a group of models with regimeswitching time-varying parameters and ...
Time evolution of external shocks on macroeconomic fluctuations in Pacific Alliance countries: empirical application using TVP-VAR-SV models
(Pontificia Universidad Católica del Perú, 2022-03)
This article provides empirical evidence on the evolution of the impact of external shocks on the
macroeconomic dynamics of the Pacific Alliance (PA) countries. For this purpose, we estimate
a family of VAR models that ...
Evolution over time of the effects of fiscal shocks in the peruvian economy: empirical application using TVP-VAR-SV models
(Pontificia Universidad Católica del Perú. Departamento de Economía, 2023-01)
This study assesses the evolving impact of fiscal policy on Peru’s economic activity in 1993Q4-2018Q2 using unrestricted and restricted TVP-VAR-SV models according to the approach proposed by Chan and Eisenstat (2018a). ...
Time-varying effects of external shocks on macroeconomic fluctuations in Peru: an empirical application using TVP-VAR- SV models
(Pontificia Universidad Católica del Perú. Departamento de Economía, 2022-03)
This study uses a family of VAR models with time-varying coefficients and stochastic volatility
(TVP-VAR-SV) to analyze the impact of external shocks on output growth and inflation in Peru in
1992Q1-2017Q1. The statistical ...
Time-Varying Effects of Financial Uncertainty Shocks on Macroeconomic Fluctuations in Peru
(Pontificia Universidad Católica del Perú. Departamento de Economía, 2024-01)
This article employs a family of VAR models with time-varying parameters and stochastic volatility (TVP-VAR-SV) to estimate the impact of external financial uncertainty shocks on a set of macroeconomic variables in Peru ...
Modelling the volatility of commodities prices using a stochastic volatility model with random level shifts
(Pontificia Universidad Católica del Perú. Departamento de Economía, 2016-03)
We use the approach of Qu and Perron (2013) for the modeling and inference of volatility of a set
of commodity prices in the presence of level shifts of unknown timing, magnitude and frequency.
The model has two features: ...
Modeling the Volatility of Returns on Commodities: An Application and Empirical Comparison of GARCH and SV Models
(Pontificia Universidad Católica del Perú. Departamento de Economía, 2020-02)
Seven GARCH and stochastic volatility (SV) models are used to model and compare empirically
the volatility of returns on four commodities: gold, copper, oil, and natural gas. The results
show evidence of fat tails and ...
