Mispricing R2

This dataset provides the Mispricing R² measure for 41 global equity markets over the period from January 1994 to June 2021. Mispricing R² is a novel proxy for systematic mispricing in international markets, capturing the extent of market inefficiency derived from market frictions and behavioral biases.
The measure is constructed using an instrumented principal component analysis (IPCA) approach based on 11 standard mispricing anomalies: net stock issues, composite equity issues, accruals, net operating assets, asset growth, investment to assets, distress, O-score, momentum, gross profitability, and return on assets.
