Complexity vs Empirical Score

• Math Complexity: 3.0/10
• Empirical Rigor: 8.0/10
• Quadrant: Street Traders
• Why: The paper uses extensive Twitter data and robust econometric specifications (e.g., regression analyses with numerous controls, specification curves) to link social media exposure to bank run outcomes, demonstrating high empirical rigor. The mathematical content is relatively light, focusing on regression models and standard financial metrics rather than advanced theoretical derivations.
