PurposeThe purpose of this article is to explain the dynamics of public appointments and present new possibilities for research in this field.Design/methodology/approachThe article is based on a systematic literature review from 2012 to 2021, identified in Web of Science, Scopus and SciELO, in English, Spanish or Portuguese. To explain the dynamics of public appointments, the following were analyzed: the nomination process; the motivations, objectives and criteria used; the results and impacts of appointments; and the profile of the nominees. The study focused only on discretionary appointments to fully public bodies and agencies.FindingsThe literature offers a limited explanation for the dynamics of appointments, by focusing on the dichotomy between loyalty and competence. Despite this, studies suggest that different contextual factors, such as administrative tradition or strategic choices, for example, determine the dynamics of appointments, indicating that it is a complex process that goes beyond the simple discussion of merit or clientelism.Originality/valueThe article presents an unprecedented analysis of the literature on the dynamics of public appointments and proposes an explanatory model that indicates that other factors, in addition to merit and loyalty, should be considered relevant for the selection criteria, the nomination process and the profile of who will be appointed. This model is useful both for the practical management of appointments and for the advancement of theory in this field and should receive improvements and future empirical evaluations.
