Fifty-five years of managerial shared leadership research: A review of an empirical field

Managerial shared leadership is a practice that goes beyond traditional ways of organising leadership functions. It is an organisational phenomenon where a few individuals share responsibility for the tasks of a managerial position. This paper reviews 67 empirical papers published in scientific journals. The review covers 55 years (1965–2019). The aim is to contribute knowledge about managerial shared leadership as a research field and offer some relevant theoretical concepts. No review to date has specifically focused on managerial shared leadership, and this paper intends to close this knowledge gap. The paper details the start of managerial shared leadership as a research field, presents a bibliometric analysis and the methodological approaches used, and describes the structural characteristics of managerial shared leadership. The paper includes a thematic content analysis of necessary and enabling antecedents and outcomes. Historically, the imprecise use of concepts has hampered managerial shared leadership’s development into a cohesive research field, so this paper develops and uses theoretical concepts to form a theoretical construct for the entire field. This construct is briefly discussed in relation to general shared leadership theory and critical leadership studies. In practice, managerial shared leadership may provide leadership solutions where there is an imbalance between demands and resources while managing complex situations.
