Outline of Final Research Achievements	This project explained whether and how vote buying occurred in external voting focusing on the case of Mexican immigrants in the US and combining the methods of survey experiments and interviews. Specifically, we conducted a list experiment using an online survey targeting Mexican immigrants in the US in the context of the 2018 presidential elections of Mexico. We found that approximately 32 percent of the respondents experienced vote-buying. Furthermore, this experimental analysis was complemented by qualitative interviews for retuned immigrants and migrant families in Puebla, Mexico as well as the leaders of Mexican immigrant organizations in Chicago, Los Angeles, and New York. As a result, we verified the causal mechanism by which buying vote across borders occurred in external voting: political parties or candidates attempted to buy the expatriates’ votes, expecting they influence voting decisions of their families in Mexico through a dense cross-border networks.
Free Research Field	政治学
Academic Significance and Societal Importance of the Research Achievements	近年、世界規模で、経済的・政治的理由から他国への移民が増加する中、移民が送り出し国・受入国の政治に与える影響は増しつつある。こうした背景の下、本研究は、３つの点で重要な学術的・社会的意義を有する。第１に、国外で行われた票買収を分析の射程に含めることで、票買収を中心とする選挙不正の実態の解明を目指し、選挙不正研究の地平を広げる。第２に、サーベイ実験により、票買収による在外市民の民主的利益代表の阻害が阻まれたのかどうか、正確に把握することが可能となる。第３に、移民の越境的なネットワークを分析枠組みに組み込むことにより、国際移民研究の発展にもつながりうる。
