Item type:Publication, Evolution of monetary policy in Peru: an empirical application using a mixture innovation TVP-VAR-SV model(Oxford University Press, 2021-12-15)This article discusses the evolution of monetary policy (MP) in Peru in 1996Q1–2019Q4 using a mixture innovation time-varying parameter vector autoregressive (VAR) model with stochastic volatility (TVP-VAR-SV) as proposed by Koop, Leon-Gonzales and Strachan. The main empirical results are: (i) the VAR coefficients and volatilities change more gradually than the contemporaneous coefficients over time; (ii) the volatility of MP shocks was higher under the pre-Inflation Targeting (IT) regime; (iii) a surprise increase in the interest rate produces gross domestic product (GDP) growth falls and reduces inflation in the long run; (iv) the interest rate reacts more quickly to aggregate supply shocks than to aggregate demand shocks; (v) MP shocks explain a high percentage of domestic variables behavior under the pre-IT regime but their contribution decreases under the IT regime. Overall, these results show that MP has contributed in Peru to lower macroeconomic volatility by (i) reducing average long-term inflation, (ii) increasing the response of GDP growth rate to interest rate, and (iii) by becoming more predictable.

Item type:Publication, Time changing effects of external shocks on macroeconomic fluctuations in Peru: empirical application using regime-switching VAR models with stochastic volatility(Springer Science+Business Media, 2022-08-24)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 regime-switching time-varying parameters and stochastic volatility (RS-VAR-SV), as proposed by Chan and Eisenstat (J Appl Econ 33(4):509–532, 2018. https://doi.org/10.1002/jae.2617). The data suggest a model with contemporaneous coefficients and constant lags and intercepts, but with regime-switching variances; and point to the existence of two regimes. The IRFs, FEVDs, and HDs show that: (i) China growth shocks have a higher impact on Peru’s output growth (around 0.8%); (ii) financial shocks contract domestic output growth by 0.3% and domestic monetary policy is synchronized with Fed rate movements; (iii) external shocks explain 35% and 70% of output fluctuations under regimes 1 and 2, respectively; and (iv) China growth shocks contributed 1.0 p.p. to the 1.1-p.p. increase (around 89%) in Peru’s output growth between regimes 1 and 2. Additionally, we validate these results by performing seven robustness exercises consisting in changing priors, reordering variables, changing variables, and using four different specifications for the baseline model. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evolution of the effects of mineral commodity prices on fiscal fluctuations: Empirical evidence from TVP-VAR-SV models for Peru(Springer Science+Business Media, 2022-04-02)This paper studies the evolution of the effects of fluctuations in mineral commodity prices on fiscal variables, especially those associated with fiscal revenues, in Peru by means of VAR models with time-varying parameters and stochastic volatility (TVP-VAR-SV). We compare different alternative specifications using the marginal likelihood and the deviance information criterion, which show that it is essential to consider stochastic volatility. It is found that an increase of 1% in the growth of mineral commodity prices generates increases of around 1.5 and 2.5% in the growth of taxes from mining and mining canon, respectively, thus reflecting a remarkable sensitivity of these variables to external shocks. In turn, these responses are increasingly more pronounced until reaching a peak around 2009 and then decrease, which is in line with the dynamics of the commodities boom. In the variance decomposition, the importance of shocks in mineral commodity prices in explaining fluctuations in taxes from mining and mining canon increases in line with the increasing tendency of mineral prices until the Great Recession, where shocks in mineral commodity prices explain between 40 and 50% of fluctuations in taxes from mining and mining canon, and then it is reduced. This shows the importance of allowing time-varying parameters and stochastic volatility in contrast with a standard VAR. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evolution of the exchange rate pass-through into prices in Peru: An empirical application using TVP-VAR-SV models(Elsevier Ltd, 2024-04-01)This study examines the evolution of exchange rate pass-through (ERPT) into import, producer, and consumer prices in Peru from 1995Q2 to 2022Q4 using time-varying parameter and stochastic volatility VAR models. Findings reveal a resurgence of ERPTs into import and producer prices since 2009, particularly during the period of a strong US dollar following the 2013 taper tantrum and from 2020 to 2022. Increased uncertainty surrounding the exchange rate and future macroeconomic policies, triggered by the political uncertainty following the 2021 general elections, may have contributed to this trend. Short-term ERPT exceeds long-term ERPT, which might reflect prevalent price dollarization in Peru's import and producer prices. Consumer ERPT remained stable at around 10% until 2009, then increased to 15%, indicating lower levels of price dollarization. This paper sheds light on ERPT dynamics in Peru, carrying implications for policymakers in emerging economies. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Time-Varying Impact of Fiscal Shocks over GDP Growth in Peru: An Empirical Application Using Hybrid TVP-VAR-SV Models(Elsevier B.V., 2023-03-01)This paper estimates hybrid TVP-VAR-SV models suggested by Chan and Eisenstat (2018a) to identify and quantify the impact of fiscal shocks on GDP growth in Peru between 1995Q1–2018Q2. According to Bayesian criteria, the best models exhibit time-varying dynamics, but not necessarily in all parameters. Considering this result, our findings suggest that: (i) fiscal shocks are significant in the whole sample according to impulse response functions, forecast error variance decomposition and historical decomposition of GDP growth; (ii) tax revenue shocks are the least important and their impact is model dependent; (iii) expenditure shocks are relevant drivers of GDP growth; and (iv) expenditure multipliers, mainly for capital spending, have been growing over the last 20 years. We recommend constant revision of estimated fiscal multipliers and suggest that, in following years, fiscal policy in Peru should be mostly driven by capital expenditure. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Does the Central Bank of Peru Respond to Exchange Rate Movements? A Bayesian Estimation of a New Keynesian DSGE Model with FX Interventions(Elsevier Inc., 2023-09-01)This paper assesses the role played by the exchange rate and FX intervention in setting monetary policy interest rates in Peru. We estimate a Taylor rule that includes inflation, output gap and the exchange rate using a New Keynesian DSGE model that follows closely Schmitt-Grohé and Uribe (2017). The model is extended to include an explicit sterilized FX intervention rule as in Faltermeier, Lama, and Medina (2017). The main empirical results show that the model that features a Taylor rule which does not respond to changes in the nominal exchange rate and considers an active use of FX interventions by the Central Bank of Peru clearly outperforms other model specifications in terms of the marginal log density. We also find that the coefficient associated with the response of the Taylor rule to inflation is close to 2 and the one associated with the output gap is greater than 1. Additionally, we find that FX interventions have become more responsive to exchange rate fluctuations during the IT period. Finally, the estimated IRFs show that FX interventions has contributed to reducing the volatility of GDP in response to productivity and terms of trade shocks in Peru. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Time-varying effects of financial uncertainty shocks on macroeconomic fluctuations in Peru(Elsevier BV, 2025-03-01)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 for the period from 1996Q1 to 2022Q4. The main findings can be summarized as follows: (i) a simple VAR model with stochastic volatility is sufficient to capture uncertainty dynamics compared to TVP-VAR alternatives; (ii) uncertainty shocks have a negative and significant impact on private investment growth in the medium and long term; (iii) the impact on private investment growth is three times greater than that on GDP growth; (iv) uncertainty shocks behave like aggregate supply shocks, leading to an increase in the inflation rate; and (v) uncertainty shocks have stronger effects in scenarios characterized by unfavorable financial conditions.3 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Lending rate sensitivity to monetary policy: a bank level empirical analysis(Emerald Publishing Limited, 2025-01-01)This paper evaluates how the monetary policy rate influences bank lending rates in Peru, focusing on various loan types from September 2010 to August 2022. Design/methodology/approach We utilize the Bai and Perron (1998, 2003) methodology to account for structural changes in the pass-through effect of monetary policy on lending rates. Findings Findings indicate a heterogeneous impact of monetary policy on lending rates, with larger effects during significant rate changes and heightened sensitivity post-2019 due to COVID-19. Originality/value This study is the first to investigate the effects of monetary policy on interest rates using segment and bank level data in Peru.1 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Evolving impacts of fiscal policy on macroeconomic fluctuations in Peru(Elsevier BV, 2025-03-01)This study assesses the evolving impact of fiscal policy on Peru's economic activity in 1995Q1-2018Q2 using unrestricted and restricted TVP-VAR-SV models as proposed by Chan and Eisenstat (2018a). The results highlight the necessity of including stochastic volatility, although there is no clear evidence for time-varying parameters. Shocks from government consumption growth and public investment growth significantly influence the forecast error variance decomposition and the historical decomposition of GDP growth. Conversely, the impact of tax revenue shocks remains weak throughout the study period. The public investment multiplier exceeds that of government consumption although both are less than 1, suggesting a limited capacity of fiscal policy to stimulate economic activity. The study also finds that external shocks (export price index growth) have a strong and positive impact on tax revenue growth. A series of robustness exercises further confirms these results.2
