The appointment of executive heads in UN treaty-based organizations

The research reported in this article seeks to understand how and why individuals are appointed to serve as executive heads of international organizations. A simple statement of the behavioral rule used in selection of executive heads is developed in the form of an executive head appointment function. The type of data available for the analysis of the appointment of executive heads in international organizations is identified, and an empirical examination of changes in emphasis in the selection of executive heads is reported. The executive head appointment function utilized in the study views appointment as an executive head as a function of six factors (three organizational, one national, and two personal). Discriminant function analysis is used to determine if the function would distinguish between individuals appointed during the period 1945-57 and those appointed from 1958-70 as executive heads in UN treaty-based organizations. It is possible to distinguish, on the basis of the specified executive head appointment function, between executive heads appointed during the two halves of the time period under study. It is therefore reasonable to conclude that the emphasis involved in the selection of executive heads has changed over time in UN treaty-based organization
