Quantifying Priorities in Business Cycle Reports: Analysis of Recurring Textual Patterns around Peaks and Troughs

Alexander Foltas (2025),
HWWI Working Papers No. 5/2025, Hamburg Institute of International Economics.
This paper proposes a novel method to uncover shifting thematic priorities in textual business cycle reports and links them to macroeconomic fluctuations. To this end, I leverage qualitative business cycle forecasts published by leading German economic research institutes from 1970-2017 to estimate the proportions of latent topics. These topics are then aggregated into broader macroeconomic subjects using a supervised approach. By extracting the cyclical components of these subjects’ proportions, I derive dynamic measures of forecasters’ thematic priorities.
Correlating the cyclic components with key macroeconomic indicators reveals consistent patterns across economic expansions and contractions. Around economic peaks, forecasters emphasize inflation-related over recession-related topics. I thus propose that forecasters’ failure to predict recessions may stem from a tendency to underestimate growth risks and overestimate inflation risks during periods of contractionary monetary policy. Around troughs, forecasters prioritize investment-related topics over general growth considerations.
