| 研究実績の概要 |
This research explores the relationship between the ideological positioning of traditional mainstream parties and the electoral fortunes of challenger parties across liberal democracies in and outside the European Union. It applies a wide range of empirical techniques to demonstrate that when the mainstream parties converge, voters are more likely to switch to challenger parties. The empirical analyses focus on both party ideology using manifesto data and voter perceptions using survey data. The findings are organized into two papers. A first paper examines the effects of European integration on actual and perceived mainstream party convergence using regressions and matching methods. A second paper tests the effects of party convergence on the electoral performance of challenger parties.

| 今後の研究の推進方策 |
In 2023, I will conduct a survey experiment in Italy to test the effects of European integration on perceived mainstream party convergence. Other surveys on the ideology and values of voters may be conducted in Japan, New Zealand, Germany and Italy.

| 次年度使用額が生じた理由 |
In the next fiscal year, I will travel to Buenos Aires (Argentina) and Los Angeles (US) to present my research at the International Political Science Association and the American Political Science Association, respectively. I will also turn these conferences papers into research articles to be published in academic journals. Furthermore, I will conduct surveys in several countries to add to the current findings.
