Abstract

Colombia is particularly affected by the El Niño Southern Oscillation (ENSO) weather fluctuations. In this context, this study explores how the adverse weather events linked to ENSO affect the inflation expectations in Colombia and how to incorporate these second-round effects into a small open economy New Keynesian model. Using BVARx models we provide evidence that the inflation expectations obtained from surveys and break-even inflation measures are affected by weather supply shocks. Later, using this stylised fact, we modify one of the core forecasting models of the Banco de la República by incorporating the mechanisms in which weather-related shocks affect marginal costs and inflation expectations. We find that ENSO shocks had an important role in both inflation and the dynamics of inflation expectations, and that policymakers should consider this fact. **** RESUMEN: Colombia es un país que esta particularmente afectado por las fluctuaciones climáticas de El Niño (ENSO). En este contexto, este estudio explora cómo los eventos meteorológicos adversos vinculados con el ENSO afectan las expectativas de inflación en Colombia y analiza cómo incorporar estos efectos de segunda ronda en un modelo neokeynesiano para una economía pequeña y abierta. Usando modelos BVARx se proporciona evidencia que tanto la inflación como sus expectativas se ven afectadas por choques de oferta climáticos. Posteriormente, y haciendo uso de este hecho estilizado, se modifica uno de los modelos centrales de pronóstico del Banco de la República y se incorporan mecanismos bajo los cuales los choques climáticos afectan los costos marginales y las expectativas de inflación. En este documento se encuentra que las fluctuaciones relacionadas con el ENSO han tenido un papel importante tanto en la inflación como en la dinámica de las expectativas y que, por lo tanto, las autoridades deberían considerar este hecho en su análisis sobre el estado actual de la economía.
