Resumen: Esta investigación aplica el análisis de textos para evaluar el rol que desempeñan la incertidumbre y el sentimiento sobre el PBI y la Demanda Interna entre enero de 2012 y diciembre de 2019 en el Perú. Se estimaron modelos de Vectores Autorregresivos (VAR) con variables proxy (Indicca y Volatilidad de la Bolsa de Valores de Lima) e Índices de Sentimiento e Incertidumbre basados en la aplicación de la Conviction Narratives Theory y en un diccionario construido a partir de textos extraídos de diarios nacionales. Se encontró una mayor correlación entre las variables de interés y los índices elaborados en comparación con los proxys existentes. Se estimaron los impulsos respuesta de shocks sobre las variables macroeconómicas y se encontró que un shock de sentimiento positivo incrementa la Demanda Interna y el PBI. En contraste, un shock de incertidumbre afecta negativamente la Demanda, PBI y en menor medida, el Consumo Interno de Cemento y la Importación de Bienes de Consumo Duradero. El impacto estimado de los indicadores de sentimiento e incertidumbre es mayor que el de los proxys sobre la Demanda Interna y el PBI, además, hay evidencia estadística de que los índices de sentimiento e incertidumbre pueden ser considerados como indicadores adelantados para estimar la Demanda Interna.
This research applies text analysis to assess the role of uncertainty and sentiment on GDP and Private Consumption between January 2012 and December 2019 in Peru. Vector Autoregressive (VAR) models were estimated with proxy variables (Indicca and Volatility of the Lima Stock Exchange) as well as Sentiment and Uncertainty Indices based on the application of the Conviction Narratives Theory and on a dictionary built from texts extracted from national newspapers. A higher correlation was found between the variables of interest and the elaborated indices in comparison with the existing proxies. The response impulses of shocks on the macroeconomic variables were estimated and resulted that a positive sentiment shock increases the Internal Demand and the GDP. In contrast, an uncertainty shock negatively affects Demand, GDP and, to a lesser extent, Domestic Cement Consumption and Imports of Durable Consumer Goods. On the other hand, the impact of the proxy variables on the variables of interest was imprecise. As a conclusion, the importance of indices based on highly available narratives is due to the fact that they capture aspects that the existing indicators, due to how they are elaborated, are not capable of. The estimated impact of sentiment and uncertainty indicators is greater than that of proxies on Domestic Demand and GDP, and there is statistical evidence that sentiment and uncertainty indexes can be considered as leading indicators for estimating Domestic Demand.
