The duration and durability of cabinet ministers

This article surveys the growing research programme on the duration of cabinet ministers. It examines some of the conceptual and methodological issues confronting research, including the nature and measurement of durability, ministerial terms and techniques. It considers some of the theories and hypotheses that have been generated by researchers. Using evidence from studies from around the world, it argues that institutional factors, including regime type, constitutional and parliamentary rules, and party systems, affect ministerial durability. Personal ministerial characteristics, such as gender, education and age, also affect durability. It examines future avenues of research in this field.
