Introduction
摘要
This study examines how investor behavioural biases influence sustainable and non-sustainable firms in the United States. Using a behavioural three-factor model, it shows that both high- and low-ESG firms are affected by overconfidence and limited attention biases, though to different extents. High-ESG firms exhibit more efficient price corrections and greater resilience during market downturns, while low-ESG firms experience more persistent mispricing.
