Purpose This paper aims to assess the concept of managerial discretion with respect to its theoretical and empirical usefulness for corporate governance research. Design/methodology/approach This paper scrutinises applied theoretical claims, definitions and methods, as well as a number of empirical studies on managerial discretion. Findings To date, no empirical definition of the concept has been presented and no measurement has been developed and tested for reliability and validity that contains all three factors of the managerial discretion concept, as proposed by Hambrick and Finkelstein (1987). Practical implications Research on managerial discretion does not provide owners and directors of boards with any advice on granting top managers a high or low degree of discretion. Originality/value This paper concludes that corporate governance scholarship will improve if it abandons the concept of managerial discretion.

Purpose The purpose of this paper is to question the usefulness of comparisons between theories on servant leadership and transformational leadership. Design/methodology/approach A review of scholarly works on these two theories is presented from the original works of Greenleaf, Burns and Bass to the current research. Findings Based on the four categories of construct clarity, two competing alternatives are identifiable in the scholarship of both servant and transformational leadership. There are thus 16 versions of each theory. Research limitations/implications The literature review contains no new empirical data. The many versions available today of each theory do not make comparisons meaningful. The prevalence of several versions of theories on servant leadership and transformational leadership implies that they are no longer specific and useful theories. Originality/value Critical comments are presented on the usefulness of comparisons between servant leadership and transformational leadership. Thus, the value of these theories is also questioned.
