A Study on Ethical Leadership in Korea: A Systematic Review and Meta-Analysis

Based on a review of empirical literature on ethical leadership in Korea, we summarize the current research trends and analyze the integrated relationships among leader-, follower-, situational-factors and ethical leadership using meta-analytic techniques to propose a set of future research agendas on ethical leadership in Korea. Based on 90 independent ethical leadership related studies published in Korean journals in social sciences disciplines, our meta-analysis results show that there is a strong relationship between follower-related factors and ethical leadership. In particular, our meta-analytic results indicate that leaderfollower interpersonal variables (i.e., LMX, trust) and in-role and extra-role performance variables (i.e., task performance, OCB, creativity, and deviance-unethical behavior) have significant relationships with ethical leadership. Further, we examine these relationships by exploring several potential moderators such as measurement of ethical leadership, research design (independence of data sources, time-related research design), and research context (nation of data sample, type of organization). Along with implications of these findings and study limitations, we discuss the future research directions for ethical leadership scholarship in Korea.
