Duverger's Law

This article tests the effects of a new electoral system that was introduced in Mongolia for the June 2016 elections. The decision to implement a first-past-the-post (FPTP) system instead of a mixed-member majoritarian (MMM) system, which was first and last used in the previous elections of 2012, was due to the April 2016 ruling of the Mongolian Constitutional Court on unconstitutionality of the list tier as one of the mechanisms for distributing seats within MMM. Through an analysis of national- and district-level results, this article addresses the question whether electoral competition at the district level was consistent with Duverger’s law and resulted in the restoration of bipartism, which had been disrupted in 2012 due to the use of MMM.

Duverger's Law

As it is well acknowledged that the electoral system is one of the fundamental rocks of our modern society, the behavior of electors engaged in a voting system is of the utmost importance. In this context, the goal of the study is to model the behavior of voters in a first-past-the-post system and to analyze its consequences on a party system. Among the assumptions of this study is Duverger’s law, which states that first-past-the-post systems favor a two-party system as the voters engage in tactical voting, choosing to vote in favor of a less preferred candidate who has better odds of winning. In order to test this assumption and to better analyze the occurrence of the strategic behavior, a laboratory experiment was created. A total of 120 persons participated in the study. An asymmetrical payoff function was created to value the voters’ preference intensity. As a result, it was observed that as voters got used to the voting system, they engaged in more tactical voting behavior in order to either maximize the gain or minimize the loss of their choice. Moreover, the iterations where voters started displaying tactical behavior featured a clustering around two main choices. The obtained results are consistent with both the empirical results of real-life elections and Duverger’s law. A further discussion regarding the change in voters’ choice completes the analysis on the strategic behavior.

Five major claims are made in our paper on strategic voting within the context of Japan's multimember single non-transferable vote (SNTV) electoral system (Fournier and Kohno, 2000). Two claims deal with the reconciliation of Steven Reed's (1990) and Gary Cox's (1997) important work on extending Duverger's law to the Japanese case, and three claims deal with the informational effects of partisan labels on strategic voting.

AbstractThis note traces the reasoning behind Riker's addenda to Duverger's law, which exempts Canada and India from its general determinism. Characteristics common to Canada and India, but not to other countries using the plurality electoral system, are examined. The study finds that the uniqueness of those two federal nations employing the simple-majority system lies in the dominance of one national party, the weakness of the conventional alternative governing party, and the persistence of ideological parties of the left.

Duverger's Law

Since the early 1990s, Steven Reed and Gary Cox have changed our understanding of Japan's multimember SNTV electoral system, by highlighting its institutional effects similar to what is known as Duverger's law in the Anglo-American context. While we offer some additional evidence to consolidate their findings, we also address an issue left unexplored in these studies, namely the role of partisan information. Under Japan's system, party labels matter in elections. We show that, while Japanese voters are generally willing to abandon the candidates without affiliation with established parties, the partisan effects produce constraints for strategic coordination.

Election Results

Akin to the previous, 2014 event, with no data on voter ethnicity, no exit polls, and few post-election analyses, the 2018 Fiji election results remain something of a mystery despite the fact that there had been a significant swing in voting in favour of Opposition political parties. There have been several studies about the election results, but most of them have been done without much quantitative analyses. This study examines voting patterns of Fiji’s 2018 election by provinces, and rural-urban localities, as well as by candidates, and also compares the 2018 and 2014 elections by spending a substantial time classifying officially released data by polling stations and individual candidates. Some of the data are then further aggregated according to the political parties to which those candidates belonged. The current electoral system in Fiji is a version of a proportional system, but its use is rare and this study will provide an interesting case study of the Open List Proportional System. At the end of the analyses, this study considers possible reasons for the swing in favour of the Opposition.

Electoral System Incentives for a Party-Serving Personal Vote

Almost All

Candidate-centric campaigns are most likely to occur when electoral system incentives to personalize do not conflict with party-based incentives. Then it makes sense for candidates to use any campaign mean to improve their chances to win a seat while also helping the party win more seats and increasing their standing within the organization. The Romanian electoral system uniquely combined mechanisms that enabled all three motivations for almost all candidates. Our analysis of the degree and determinants of personalization in the 2012 parliamentary elections illustrates that electoral system incentives were key factors driving campaign personalization as a party-congruent rather than adversarial campaign strategy.

2012 Election

While electoral discontent has been the enduring feature of constitutional democracy in Lesotho since independence, disagreement over electoral system is a fairly recent phenomenon. When the country attained independence in 1966 from Britain, electoral system was not necessarily one of the topical issues of pre-independence constitutional negotiations. The major issues were the powers of the monarch, the office of prime minister, the command of the army and many more.  It was taken for granted that the country would use the British-based plurality electoral system.  This is the system which the country used until early 2000s when the electoral laws were reformed to anchor a new mixed electoral system.  When the new electoral laws were ultimately passed in 2001, the country transitioned from a plurality electoral system to a two-ballot mixed member proportional system. By this time, electoral system had acquired prominence in politico-legal discourse in Lesotho.  In the run-up to 2007 elections, bigger political parties orchestrated the manipulation of electoral laws which culminated in clearly distorted electoral outcomes. The manipulations motivated further reforms in the run-up to 2012 election which resulted in the single-ballot mixed member proportional system. The purpose of this paper is to critically evaluate how electoral laws have anchored electoral system reforms throughout the various historical epochs in Lesotho since independence. The paper contends that while the country has been courageous, unlike most of its peers, to introduce far-reaching electoral system changes, the reform of electoral laws has not been so helpful in attaining the higher objectives of political inclusivity, constitutionalism and stability in Lesotho.
