Sustainable by Ideology? The Influence of CEO Political Ideology and Ivy League Education on ESG (Environmental, Social, and Governance) Performance
基于高层梯队理论，研究CEO政治意识形态和常春藤教育如何影响企业ESG绩效，发现自由派CEO提升ESG绩效，而常春藤教育背景的CEO反而抑制ESG绩效。
ABSTRACT Building on upper echelons theory, this study posits that political ideology serves as a foundational factor influencing whether CEOs prioritize environmental, social, and governance (ESG) outcomes, whereas Ivy League education acts as a contextual factor that moderates this relationship. Analyzing data from S&P 900 manufacturing firms, the findings reveal that liberal CEOs enhance ESG performance—particularly in the social and governance pillars—in contrast to their conservative counterparts. CEO political ideology's effect on ESG performance does not depend on whether CEOs graduated from an Ivy League institution. Instead, Ivy League–educated CEOs directly deter ESG performance, possibly due to specific values, perspectives, and social connections shaped by their elite educational background. This study contributes to upper echelons theory by illuminating two critical microlevel factors—CEO political ideology and elite education—that shape firms' ESG strategy, offering valuable implications for boards and stakeholders when selecting and evaluating corporate leadership.
