This document from the XXVI Meeting of the Central Bank Researchers Network at CEMLA explores the relationship between monetary policy communication tone and inflation expectations. The authors, Carotta, Mello, and Ponce from Banco Central del Uruguay, discuss the importance of effective and perceived tone in anchoring inflation expectations and propose new indicators for perceived tone and readability. The study is based on a survey of BCU members and advanced Economics students, and the findings suggest that both tone and readability have a statistically significant impact on inflation expectations.

Contribute evidence on the impact of monetary policy communication on inflation expectations of the general public (firms): I (^) A negative and statistically significant relationship between the tone of monetary policy communication and inflation expectations I (^) On top of the tone, the readability of monetary policy communication has a statistically significant marginal contribution To so doing: I (^) Propose a new perceived tone indicator by implementing a survey I (^) Compute readability and perspicuity indicators of monetary policy statements =⇒ Efforts to continuing making monetary policy communication more accessible to the general public may be worth
We propose an indicator of the tone of monetary policy communication that accounts for the perception of readers. The indicator of perceived tone does not focus on the contain of the communications but on the perception or sentiment of the readers. If agents were totally rational, there should be no discrepancies between the indicators. But they aren’t. Individuals may slowly modify their perceptions by discarding any new information that is not aligned with their previous beliefs (Rabin 1993), They may suffer a confirmation bias by giving more weight to new information that reaffirms their previous thought (Tversky and Kahneman 1973). The set of prior information available to an agent can affect the interpretation of the communications (Babcock and Loewenstein 1997).
Distributed in two batches in a three-month period, between September and November 2020. BCU members and advanced Economics students. Participation was voluntary. The text of the monetary policy releases was divided into sentences, and each question contains a single sentence. The respondents were asked to classify according to the tone perceived as : ‘contractive’, ‘expansive’ or ‘neutral’ or ‘does not apply’. Questions (a sentence of the 586 for all the statements) are assigned randomly. Background information: Inflation, GDP growth, policy rate, unemployment. 49 respondents 1.310 responses

The reading of the monetary policy communication has been made simpler, although it persists at a high level of difficulty.

The reading clarity in communication has improved, but still remains at ”difficult” or ”somewhat difficult” levels.
Was monthly sent to 500 firms, with an average response ratio of 77% since October 2009, and a minimum response ratio of 44%. 591 companies throughout the entire period were covered by the sample, between October 2009 and March 2020.

Inflation and expectations are anchored in a higher level, above the target almost all the period of analysis.
