The relative importance of industrial relations ideas in politics: A quantitative analysis of political party manifestos across 54 countries
利用比较宣言项目数据，分析了54个国家75年间1132个政党的宣言，发现政党特征、对其他政党的回应以及经济政治条件能预测产业关系思想（如亲工人和反工会言论）的重要性，且亲工人思想在选举中对选民有影响。
Abstract Ideas are important but hard to quantify, making large‐scale, quantitative analyses difficult. Political parties are important ideational contributors, and their election year manifestos provide explicit compilations of their ideas. Using Comparative Manifesto Project data, we propose three channels through which ideas enter into manifestos and examine the fraction of manifesto content devoted to pro‐worker and anti‐union statements to measure the importance of these ideas. Multivariate analyses across 54 countries, 75 years, and 1132 parties uniquely uncover predictors of industrial relations ideas, including party characteristics, responses to other parties, and economic and political conditions. Further, pro‐worker ideas matter to voters during elections.
