Comprehensive Retrospective Voting in Mixed Electoral Systems: Evidence from the 2016 Korean Legislative Election

Abstract

AbstractPerformance-based retrospective voting is a fundamental mechanism of democracy. A good deal of scholarship has examined this electoral mechanism, but the extant studies have two omissions. First, there is little research that considers several retrospective evaluations together using an incumbent voting model. Second, there is little research that examines the difference in the effects of voters’ retrospective evaluations on two different ballots in mixed electoral systems. To fill these omissions, this article tests a comprehensive retrospective performance voting model in a mixed electoral system. Specifically, this article examines the effects of voters’ retrospective economic evaluations of economic performance at the national and personal levels, human rights, corruption, welfare protection, and foreign policy on vote choice for the incumbent party in the 2016 Korean legislative election in which voters had two ballots: one for the party list vote and one for the district vote. By using multinomial logistic regression models, this article finds that among the six retrospective evaluation categories, judgments of national economic performance at the national level, human rights, and foreign policy have a statistically significant impact on the likelihood of voting for the incumbent party in party list vote choice, whereas only voters’ evaluation of foreign policy matter in the district level vote decision. The results imply that Korean voters consider various aspects of government performance, such as the conditions of human rights and relationships with other countries, rather than just focusing on the economy. The retrospective voting behavior of Korean voters differs between party list and district level ballots.
