Oscillatory dynamics between language usage and economic activity

Abstract

Over the past two centuries, the frequency of word usage in major Western languages has exhibited small amplitude regular cycles, superimposed on larger background trends. We show that these cycles of word usage organize into semantically coherent clusters that track, interact with, or precede macroeconomic rhythms. To explore the nature of this interaction, we build on a minimal mathematical model that captures usage dynamics through parameters linked to real world processes. Parameter fitting reveals that word usage operates near a Hopf bifurcation, a critical regime associated with heightened sensitivity, uncovering a robust and specific coupling between language usage and economic activity. In linguistic datasets that allow long term quantitative analysis, rooted in capitalist contexts, this coupling appears as an oscillatory dynamic, reflecting a feedback process in which language both shapes material reality and manages the changes it produces.
