The length of ministerial tenure in the UK, 1945-97

Abstract

We analyse the determinants of ministerial hazard rates in Britain from 1945 to 1997. We focus on three sets of attributes (i) personal characteristics of the minister; (ii) political characteristics of the minister; and (iii) characteristics pertaining to the government in which the minister serves. We find that educational background increases ministers' capacity to survive, that female ministers have lower hazard rates and older ministers have higher hazard rates. Experienced ministers have higher hazard rates than newly appointed ministers. Ministerial rank increases a minister's capacity to survive, with full cabinet members having the lowest hazard rates in our sample. We use different strategies to control for the characteristics of the government the minister serves in. Our results are robust to any of these controls.
