Unsuccessful Success? Failed No-Confidence Motions,Competence Signals,and Electoral Support

Abstract

If no-confidence motions are primarily motivated by bringing down governments, why do only approximately 5% of no-confidence motions in advanced parliamentary democracies from 1960 result in the termination of government? In this project the author addresses this puzzle by developing a formal model of the electoral benefits of no-confidence motions and tests these hypotheses with the use of an original data set. No-confidence motions represent highly visible opportunities for opposition parties to highlight their strength or ability compared to the government in the hopes of improving their vote shares. The author finds support for the signal-based theory on a sample of 20 advanced parliamentary democracies from 1960 to 2008. Although no-confidence motions result in decreases for the government parties, the opposition parties that propose the motion experience boosts in vote share. This relationship is even stronger when the proposing party is an alternative governing possibility—illustrated by the conditioning impacts of the number of parliamentary parties and the opposition party’s ideological extremism. This provides an explanation as to why opposition parties would continue to challenge the government even though the motions are likely to fail.
