Abstract: We study convergence in the attention of decision‐makers across the insurance and banking industries. Our analysis is based on textual risk disclosures (10‐K reports, 2006–2018), providing a snapshot of corporate priorities and contexts. We theoretically link convergence with decision‐making contexts via the Attention‐Based View. Leveraging strategic management theory, we identify antecedents of convergence in attention and, therefore, potentially, risk contagion. These include common trends in the macro‐environment, substitution threats, and management fashions. We combine this theoretical framework with machine learning tools to create quantitative measures of convergence in attention and its antecedents. We find that the proposed measure of convergence is predictive of inter‐ and intra‐industry stock correlations. Finally, based on regression and sensitivity analyses, we identify the relative importance of different antecedents, showing that shared risk management fashions largely drive Inter‐industry convergence in attention. This highlights challenges when interpreting regulatory text data in the context of predicting contagion risk.
