Assessing the authority of political office-holders: The leadership capital index

This article argues that the extent to which political office-holders can effectively attain and wield authority is a function of the stock of ‘leadership capital’. Drawing on the concept of political capital, the article defines leadership capital as aggregate authority composed of three dimensions: skills, relations and reputation of a leader. Leadership capital ebbs and flows over time within a trajectory of acquisition, expenditure and inevitable depreciation. The article presents a Leadership Capital Index (LCI) that systematically maps out the three broad areas combining concrete measures with interpretive aspects. This can be used as a tool for systematically tracking and comparing the political fortunes of leaders in a way that is both more nuanced and robust than exclusive reliance on the latest approval ratings. An illustrative case study of Tony Blair is used to demonstrate the LCI. The article concludes by discerning several promising paths for future development of the LCI.
