Tweeting Inflation: Real-Time measures of Inflation Perception in Colombia

Jonathan Alexander Muñoz-Martínez, David Orozco and Mario Ramos-Veloza

Borradores de Economia from Banco de la Republica de Colombia

Abstract: This study follows a novel approach proposed by Angelico et al. (2022) using Twitter to measure inflation perception in Colombia in real time. By applying machine learning techniques, we implement two real-time indicators of inflation perception and show that both exhibit a dynamic similar to inflation and inflation expectations for the sample period January 2015 to March 2023. Our interpretation of these results suggests that our indicators are closely linked to the underlying factors that drive inflation perception. Overall, this approach provides a valuable instrument for gauging public sentiment towards inflation and complements the traditional inflation expectations measures used in the inflation–targeting framework. **** RESUMEN: Este estudio sigue un enfoque novedoso propuesto por Angelico et al. (2022) para la medición en tiempo real de la percepción de la inflación en Colombia utilizando Twitter. Mediante la aplicación de técnicas de aprendizaje automático, calculamos dos indicadores en tiempo real de la percepción de la inflación y mostramos que exhiben una dinámica comparable a la inflación y las expectativas de inflación, lo que sugiere que nuestros indicadores están estrechamente relacionados con los factores subyacentes que impulsan la percepción de la inflación entre enero de 2015 y marzo de 2023. En general, este enfoque proporciona un medio valioso para evaluar el sentimiento público hacia la inflación y ofrece una perspectiva complementaria a las medidas de expectativas de inflación tradicionales utilizadas en el marco de la política de inflación objetivo.
