In the Colombian case, ENSO had a significant impact on consumer food prices during the strongest event in 2015. Our research evaluates the relationship between ENSO and Colombian food inflation growth by using a smooth transition non-linear model. We estimate the impacts of a strong ENSO on food inflation growth by adopting Generalized Impulse Response Functions (GIRFs) and the results suggest that the weather shocks are transitory and asymmetric on inflation. A strong El Niño shock has a significate effect on the food inflation growth from six to nine months after the shock and the accumulated elasticity is close to 465 basic points. We build the GIRFs for eight different episodes associated with a strong El Niño in the period corresponding from March 1962 to December 2018 and there is no evidence of changes in the size of Colombian food inflation growth responses over time.18 páginas : gráficas, tablasPDFengOpen AccessNonlinear relationship between the weather phenomenon El Niño and Colombian food pricesWorking paperC32 - Time-Series Models; Dynamic Quantile Regressions; Dynamic Treatment Effect Models; Diffusion Processes; State Space ModelsC50 - Econometric Modeling: GeneralE31 - Price Level; Inflation; DeflationEl Niño Southern Oscillation (ENSO)Non-linear smooth transition modelsInflationCambios climáticos -- Efectos sobre la agricultura -- ColombiaAlimentos -- Precios -- ColombiaAlimentos -- Precios -- Efectos climáticos -- ColombiaEl niño (Corriente marítima) -- Efectos sobre la agricultura --ColombiaAcceso abiertoAtribucion-NoComercial-CompartirIgual CC BY-NC-SA 4.0Cambio climático
