Abstract

Understanding the pass-through effect (PTE) is crucial for policymakers of a small open economy such as Costa Rica. In this paper, we propose an endogenous regime-switching vector autoregression (RS-VAR) model to study the exchange rate pass-through effect in Costa Rica. We identify two regimes: High PTE and Low PTE. This model allows the transition probabilities to be influenced by endogenous variables such as inflation, oil prices, and the exchange rate. We find that: i) the PTE is 4.5% in the low regime and 60% in the high regime, ii) a low PTE results from periods of high exchange rate volatility, and iii) a surprise inflation shock increases the probability of low pass-through. Given the evidence, we recommend considering the PTE as oscillating between periods of high and low magnitude instead of having a single value. ***Resumen Entendiendo el efecto de traspaso (ET) es crucial para la conducción de políticas de una economía pequeña y abierta como la de Costa Rica. En este documento, proponemos un modelo de vectores autorregresivos con cambio de régimen endógeno (RS-VAR) para estudiar el efecto de transmisión del tipo de cambio en Costa Rica. Identificamos dos regímenes: ET alto y ET bajo. Este modelo permite que las probabilidades de transición sean influenciadas por variables endógenas como la inflación, los precios del petróleo y el tipo de cambio. Encontramos que: i) el ET es de 4.5% en el régimen bajo y de 60% en el régimen alto, ii) un bajo ET resulta de períodos de alta volatilidad del tipo de cambio y, iii) un choque de inflación aumenta la probabilidad de una baja transmisión. Dada la evidencia, recomendamos considerar el ET oscila entre períodos de alta y baja magnitud en lugar de tener un valor único.
