本研究使用了33个国家50年的数据，分析了总统候选人有效人数的制度决定因素。我发现总统选举公式-多数与多数决胜-有一个强大的和重要的影响，有效的候选人数量，从而提供了最实质性的支持，迄今为止，在总统一级的Duverger的主张。与以往的跨国研究不同，我还测试了现任总统候选人的存在或缺席的影响。任职者的存在对候选人的实际人数产生了重大的减少影响。
This study employs data from 33 countries over a 50-year period to analyze the institutional determinants of the effective number of presidential candidates. I find the presidential electoral formula-plurality versus majority runoff-to have a strong and significant impact on the effective number of candidates, thereby providing the most substantial support thus far for Duverger's propositions at the presidential level. Unlike previous cross-national studies, I also test for the effect of the presence or absence of an incumbent presidential candidate. The presence of an incumbent has a significant reductive effect on the effective number of candidates.
