    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.

    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.

    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.
