Government survival in Western multi-party democracies

Abstract Based upon findings in other fields in the social sciences, it is proposed in this article that cooperation between government parties can be induced when parties in governments are able to exercise credible exit threats. As stability is more likely to be induced by cooperation than by defection, more durable governments can be expected. The possibility for credible exit threats in a government is operationalized via the presence of a dominant party in the government. The corresponding prediction is tested against a data set that contains 261 postwar governments in twelve western multiparty democracies. In the event history analyses of government survival, I control for variables pertaining to the bargaining environment, bargaining complexity, and the ideological diversity of the governments. It is found that the presence of dominant parties in governments does indeed enhance the survival time of governments.
