Abstract

In this paper we present the results of a dictionary-based text analysis of articles from the economic sections of four Serbian daily newspapers, caried out to estimate if those articles contain useful information for assessing inflationary pressures. We analyzed 117,113 economic articles in total for the period 2007–2022, by counting terms related to inflation and price rises and price falls, or counting texts containing those terms. Measures of newspaper inflation sentiment, obtained in this way, were found to be highly correlated with inflation, mainly driven by the periods of large inflation swings. During the period of stable inflation, the correlation is significantly lower. Causal relationship clearly goes from the newspaper inflation sentiment to inflation, and simple inflation models with the sentiment as an explanatory variable beat benchmark AR model in the out-ofsample forecast. We conclude that newspaper inflation sentiment can be used as an indicator of inflationary pressures, especially during periods of high inflation volatility.
