The psychological effect of electoral systems in founding elections

In this research note, I revisit the conventional wisdom about when the psychological effect of electoral systems is observed. I rely on data from the first presidential and legislative elections in 45 third- and fourth-wave presidential and semi-presidential regimes to show that the psychological effect of electoral systems manifests itself in the first election. The effective number of legislative parties is significantly higher than the effective number of presidential candidates in the first election when the electoral system in legislative elections is more permissive than in presidential elections
