Political Institutions and Policy Choices: Evidence from the United States
利用美国丰富的制度多样性，综述了制度规则、政治代表与政策结果关系的实证证据，并更新了相关研究，提出新的探索性研究方向。
A rich array of institutional diversity makes the United States an excellent place to study the relationship between political institutions and public policy outcomes. This essay has three main aims. First, it reviews existing empirical evidence on the relationship between institutional rules, political representation and policy outcomes. It aims to place the literature into a broader context of theoretical and empirical work in the field of political economy. Second, it develops a parallel empirical analysis that updates studies in the literature and re-examines some of the claims made, in a setting unified both in terms of policy outcomes and the period under study. Third, the paper develops some new directions for research, presenting a small number of novel exploratory results.
