Electoral Rules and Legislative Parties in the Ukrainian Rada

Critics of Ukraine's single-member district majoritarian and mixed-member majoritarian electoral systems argue that they undermined the efficiency of the Supreme Rada by permitting nonpartisan single-member district deputies to enter the legislature in large numbers. Such deputies changed parties and ignored party positions. This article argues that the effect of the differences in how legislators are elected is dependent upon whether legislators are partisans. The statistical analysis of party switching and party cohesion in the Rada from 1998 to 2002 shows that nonpartisan single-member district deputies were the most likely to switch parties and the least cohesive.
