Abstract: Abstract Scholars have suggested that leaders’ ethical failures at the beginning of the twenty-first century have raised awareness about the importance of ethical leadership (EL). Yet, there has been no systematic effort to evaluate whether this awareness indeed led to changes in EL or how followers react to this leadership style over time. To address this gap, we examine the evolution in EL means, variability, and its associations with follower outcomes between 2004 and 2019. Our cross-temporal meta-analysis included 359 independent samples from 314 studies published between 2005 and 2020 and focused on followers’ ratings of their leaders using the Ethical Leadership Scale (ELS; Brown et al., in Organizational Behavior and Human Decision Processes, 97(2), 117–134, 2005). Using cubic spline meta-regressions, our results indicated no global changes in EL mean levels and variability across the 15-year period. Nevertheless, country-level comparisons revealed different EL-trends in China (i.e. decrease) versus the United States (i.e. stable), and further moderation analyses highlighted the role of cultural value dimensions and national corruption rates. Finally, we also found that the relationship between EL and desirable follower outcomes (e.g. organizational citizenship behavior) became gradually stronger over time on a global level. These results provide a solid empirical basis to evaluate cross-temporal trends in EL and its (changing) impact on follower outcomes across the globe.
