Complexity vs Empirical Score

  • Math Complexity: 2.5/10
  • Empirical Rigor: 8.5/10
  • Quadrant: Street Traders — practical and empirical, lighter on theory

Why this score: The paper uses standard regression models and index construction without advanced mathematics, but is heavily data-driven with comprehensive datasets (Compustat, ISS), large sample sizes (2538 firms), and detailed backtesting of governance indices against firm valuation metrics like Tobin’s Q.
