    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.

    Effects of External Shocks on Macroeconomic Fluctuations in Pacific Alliance Countries
    (Elsevier B.V., 2023-07-01)
    Given Pacific Alliance (PA) countries’ dependence on the external sector amidst volatile global financial conditions and increased trade openness, it is important to understand the time-varying impact of external shocks on these economies to assess their resilience. We use data for 1994Q1-2019Q4 and VAR models with time-varying parameters and stochastic volatility to study the heterogeneity of responses to financial, real, and nominal external shocks. The results suggest that external shocks have played a significant role in domestic cycles (50% on average), but their impact became temporarily larger during the global low-interest-rate period; i.e., the impact of export price and Fed rate shocks on GDP increased the most, peaking in 2002–2011, whereas the effect of shocks originating in China, although the largest, remained stable. In addition, a more predictable and countercyclical monetary policy in response to commodity price shocks diminished the transmission of external shocks, thereby increasing PA economies’ external resilience.
