Abstract
This study investigates the effects of Directors’ and Officers’
Liability Insurance (D&O insurance) coverage and managerial and board
overconfidence on firm’s Environmental, Social, and Governance (ESG)
performance. Using a sample of 1,590 non-financial firms listed on the Taiwan
Stock Exchange and the Taipei Exchange over the period 2015–2020, this study
examines whether D&O insurance and behavioral traits of decision makers
influence firms’ ESG outcomes. Prior literature suggests that D&O insurance
mitigates expected litigation losses, facilitates executive retention, and
enhances external monitoring, thereby strengthening corporate governance.
However, D&O insurance may also induce moral hazard and speculative
behavior. Moreover, while ESG engagement can function as a risk management
mechanism, overconfident boards and managers tend to underestimate downside
risks and expected losses, potentially reducing ESG investment. Based on
correlation analyses and multivariate regression estimations, the empirical results
indicate that higher levels of D&O insurance coverage are positively
associated with ESG performance, whereas firms characterized by overconfident
boards and management exhibit significantly poorer ESG performance.
