✦ Synopsis
Contrary to Duverger's Law, there exist multi-party systems in conjunction with simple majority single-ballot systems. At least three exceptions exist to this "law". offer explanations for two of the most prominent exceptions, i.e. Canada and India. 1 also discuss another exception, Great Britain. In this paper, 1 use a simple one-dimensional spatial model to show that a multi-party system can be supported under a simple majority single-ballot system. This explanation depends on the way political parties exit the system. If parties decide sequentially whether or not to exit, a multi-party system can not be maintained. If political parties make this decision simultaneously, a multi-party system may be able to sustain itself. * 1 am grateful to Evelyn Fink, Ken Shepsle, and Gordon Tullock for their very helpful comments. 1 would especially like to thank John Kautsky who introduced me to Duverger's Law.
