The Political Economy of the Prussian Three-Class Franchise
研究了普鲁士三级选举制度（经济精英在政治上被过度代表）如何影响政策，发现选区投票不平等程度越高，议员越倾向支持自由主义政策，尤其在大型工业地区更明显。
How did the Prussian three-class franchise, which politically over-represented the economic elite, affect policies? Contrary to the predominant and simplistic view that the system allowed the landed elites to capture most political rents, we find that members of parliament from constituencies with a higher vote inequality support more liberal policies, gauging their political orientation from the universe of roll call votes cast in parliament during Prussia’s rapid industrialization (1867–1903). Consistent with the characteristics of German liberalism that aligned with economic interests of business, the link between vote inequality and liberal voting is stronger in regions with large-scale industry.
