Purpose – Authentic leadership and psychological ownership appear to be at somewhat similar stage of construct evolution. In the present study, the author asks two research questions: first, how authentic leadership relates to psychological ownership and second, how dyadic duration influences this relationship. The paper aims to discuss these issues. Design/methodology/approach – Using correlational research design, the author collected cross-sectional data from 182 Indian professionals working in various organizations in India. The author used structural equation modeling to test the study hypotheses. Findings – The results showed that authentic leadership positively influenced organization-based promotive psychological ownership; however, it shared no relationship with preventive psychological ownership or territoriality. Relational transparency and self-awareness factorials of authentic leadership influenced belongingness and self-efficacy factorials of psychological ownership beyond what authentic leadership as the second-order factor could account for. Leader self-awareness negatively related to follower self-efficacy. Authentic leadership completely accounted for the effects of moral perspective and balanced processing factorials on psychological ownership. Dyadic duration was not found to have significant moderation effect. Research limitations/implications – Overall, the findings imply that authentic leadership may make followers dependent and allow less relational substitutability. Moral perspective may be more central to authentic leadership construct than self-awareness. Moreover, it may not be appropriate to consider territoriality as a part of psychological ownership construct. Originality/value – The author believes that it is the first study to investigate the factorial-level interrelations between authentic leadership and psychological ownership. It can help in advancing authentic leadership theory and refining psychological ownership construct.

Around 240 B.C., Eratosthenes made what is considered to be the most famous and accurate of the ancient measurements of the circumference of the Earth.1 It was accomplished by making presumably simultaneous measurements of the angles of the shadows cast by a vertical stick at Syene (today known as Aswan) and another at Alexandria, at noon on the day of the summer solstice (about June 21 every year). From these measurements, and knowing the distance from Syene to Alexandria along the assumed same meridian of longitude, Eratosthenes was able to provide a remarkably accurate estimate of the radius of the Earth.
