Replacing Cabinet Ministers : patterns of ministerial stability in parliamentary democracies - New York, NY : Cambrige University Press, May 2008

We examine the stability of individual ministers across parliamentary democracies. Our data show that this stability is only loosely related to the stability of cabinets, making it impossible to rely primarily on arguments about cabinet duration to explain patterns of individual stability. We argue that to explain patterns of individual stability, it is useful to focus on the problems that party leaders have in identifying which individuals have the qualities necessary to do their jobs well. The institutional powers of ministers, coalition attributes, and party-specific variables should affect the uncertainty that party leaders have about which individuals will be successful ministers, on one hand, and the ability of party leaders to replace unsuccessful ministers, on the other. Our empirical tests support these arguments. The analysis therefore has implications for expectations regarding the circumstances under which minister stability should positively or negatively influence the policymaking performance of government
