Individual and Collective Performance and the Tenureof British Ministers 1945-1997

Abstract

We study the effects of individual and collective ministerial performance on the length oftime a minister serves in British government from 1945-97, using the number ofresignation calls for a minister as an individual performance indicator and the cumulativenumber of such calls as an indicator of government performance. Our analysis lendssupport to a 'two-strike rule': ministers facing a second call for their resignation have asignificantly higher hazard than those facing their first, irrespective of the performance ofthe government. A minister's hazard rate is decreasing in the cumulative number ofresignation calls; but conditional on receiving a first resignation call, the hazard rateincreases with the number of calls that all government ministers have faced in the past.Our message is that collective ministerial performance is a key determinant of whether aminister survives his first resignation call.
