  • Legislative malapportionment in Asia

    Kasuya Y., Kamahara Y., Building Inclusive Democracies in ASEAN, 2018.01

    　View Summary

    Legislative malapportionment refers to the disparity in the number of registered voters across districts. This is an aspect of the electoral system that concerns not only democracies but also autocracies with regularly held elections. In this regard, this study is not about making democracies more inclusive, but about making an institution associated with democratic politics more inclusive in both democratic and authoritarian regimes in Asia. Malapportionment is a common problem in many legislative elections. If a country uses an electoral formula with a single nationwide district, there is no malapportionment; in this instance, the country has a perfectly apportioned electoral system. By contrast, in a malapportioned system, the votes of some citizens residing in certain geographic areas carry more weight than the votes of citizens in other areas within the same country. Among the world’s electoral systems, only a few nations (e.g., Israel, Namibia, and Sierra Leone) have a single nationwide constituency, and most countries that delimit their constituencies have some degree of malapportionment.

  • The Perils of Parliamentarism: Executive Selection Systems and Democratic Transitions from Electoral Authoritarianism

    Higashijima M., Kasuya Y.

    Studies in Comparative International Development （Studies in Comparative International Development)  57 （ 2 ） 198 - 220 2022.06

    ISSN  00393606

    　View Summary

    Why are some electoral authoritarian regimes immune to democratization for decades while others not? This article explores the impact of executive selection systems on democratic transitions from electoral authoritarianism. We argue that under electoral authoritarian regimes, Parliament-based systems permit dictators to more effectively deter democratization compared to Presidential systems. This is because Parliament-based systems indirectly allow electoral manipulation to achieve a victory at the ballot box, such as through gerrymandering and malapportionment. Parliament-based systems also make it difficult for opposition parties to coordinate and incentivize autocrats and ruling elites to engage in power-sharing and thus institutionalize ruling parties. We test our hypothesis as well as the underlying mechanisms employing a dataset of 93 electoral authoritarian countries between 1946 and 2012. Cross-national statistical analyses with instrumental variables estimation provide supporting evidence for our theory.

  • Voters’ perceptions and evaluations of dynastic politics in Japan

    Miwa H., Kasuya Y., Ono Y.

    Asian Journal of Comparative Politics （Asian Journal of Comparative Politics)   2022

    ISSN  20578911

    　View Summary

    Political family dynasties are a staple part of Japanese politics. According to one study, Japan has the fourth highest number of dynastic politicians among democratic countries, after Thailand, the Philippines, and Iceland. As a result, many scholars have qualitatively studied how these political families are born and managed. In contrast to the wealth of qualitative studies on this subject, however, few quantitative studies on Japanese political dynasties focus on how voters view them. To understand this question, we conducted two nation-wide surveys. Our major findings are that while the majority of respondents dislike dynastic candidates, they also value certain attributes of those candidates, such as their political networks, their potential for ministerial appointments, and their ability to bring pork projects to their constituencies. These results fill a gap in benchmark information on dynastic politics in Japan and are a departure from existing studies that show Japanese voters are neutral regarding whether a candidate is from a dynastic family in voting decisions.

  • The shift to consensus democracy and limits of institutional design in Asia

    Kasuya Y., Reilly B.

    Pacific Review （Pacific Review)   2022

    ISSN  09512748

    　View Summary

    A ‘majoritarian turn’ identified by scholars of Asian democracy in the 1990s saw the rise of mixed-member majoritarian electoral systems and more centripetal party competition across both Northeast and Southeast Asia. In this paper, we argue that since the 2000s, the institutional pendulum has shifted, with more consensual approaches to democracy appearing to better represent key identity cleavages of gender, ethnicity, and territory—a trend evident not just in East Asia but South Asia as well. This new ‘Asian model’ typically involves increasing the proportional components of existing electoral formulas and grafting gender quotas, multiethnic party lists, and quasi-federal elements onto ostensibly majoritarian state structures. We show that these reforms have, as intended, mostly increased female and ethnic minority representation and decentralized governance structures. At the same time, however, these de jure changes are not associated with de facto political development in terms of greater democratic quality, counter to theoretical expectations. Indeed, democracy has declined across most of Asia at the same time as its democratic institutions have become more consensual.

  • Is the justice frame effective in mobilizing support for human rights violations? Evidence from the Philippines

    Calimbahin C.A.A., Kasuya Y., Miwa H.

    Asian Affairs(UK) （Asian Affairs(UK))   2022

    ISSN  00927678

    　View Summary

    Effective message framing motivates individuals to act for and defend human rights. What effective message framing motivates individuals to defend human rights? Recent experiment-based framing studies show that personal frames are more successful than informational or motivational frames in increasing the advocacy activities of human rights organizations. This study tested the justice frame using the Philippine case of extrajudicial executions. Employing internet-based survey experiments, we tested the effects of the justice frame on consensus and action mobilizations as well as the three frames mentioned above. Our results showed that combining justice and the personal frame is more effective. We also examined emotions inflicted by framing. Our results reveal an association between empathy and anger as a reaction that connects exposure to personal frame and mobilization.

  • Democratic backsliding in the Philippines: Are voters becoming illiberal?

    Kasuya Y., Calimbahin C.A.A.

    Asian Journal of Comparative Politics （Asian Journal of Comparative Politics)   2022

    ISSN  20578911

    　View Summary

    Democratic backsliding by incumbents is one of the most prevalent forms of backsliding in recent global trends of democratic erosion. Understanding the attitude of voters toward backsliding incumbents is crucial because popular support is the basis of legitimacy for these incumbents. This article studies voter attitudes in the Philippines, where democracy was subverted by the incumbent president, Rodrigo Duterte, who served from 2016 to 2022. Specifically, we examine the validity of the claim that Filipino voters are acquiring a “taste for illiberal rule” made by some scholars. First, we analyzed the survey data regarding the support for various types of political systems, where part of the data comes from our originally commissioned survey at the Social Weather Stations. Second, we explored Pulse Asia's longitudinal survey data on martial-rule support. Our investigation of these survey data did not find substantive support for the “taste for illiberal rule” proposition. Further, we argue that Filipino voters are contingent supporters of illiberal politics while supporting the procedural principles of democracy at the baseline.

  • The transformation of dominant parties in Asia: Introduction to the special issue

    Kasuya Y., Sawasdee S.

    Asian Journal of Comparative Politics (Asian Journal of Comparative Politics)  4 ( 1 ) 3 - 7 2019.03

    ISSN  20578911

    　View Summary

    © The Author(s) 2019. Dominant political parties have been the subject of study since the 1950s. As they have emerged both in democracies and non-democracies, they have become an intriguing research theme for scholars who study politics in a variety of world regions. This introductory note to the special issue on the transformation of dominant parties in Asia first reviews how “dominant parties” are defined by scholars who study this subject. Then, it turns to a discussion of the existing research on dominant parties and analyzes how scholars have examined the question of how they emerge and are sustained. Lastly, the articles included in this special issue are introduced.

    　View Summary

    This project analyses the situation, causes, and consequences of legislative malapportionment around the world. It has three research components: (1) measuring the degree of malapportionment, (2) investigating the causes of malapportionment, and (3) analyzing the its consequences. The first part yielded the database that compiles the degree of lower chamber malapportionment for 140 countries. Several papers were written on the causes of malapportionemnt. The main findings are that the degree of malapportionment increases as the electoral competition becomes more competitive, and decreases as the degree of executive constraints (such as the presence of independent judiciary). As for the consequences, members of this project found that malapportionment harms economic development of overrepresented districts in the case of Brazil. In the context of electoral authoritarianism, it reduces the electoral violence.
