How does fractionalization affect political collaboration on reform? We develop a theory to explain observable variation in legislative output over time and policy areas. We show how the properties of a reform project determine the extent to which fractionalization affects political collaboration on reform. We apply our framework to the case of Lebanon and present mixed-methods evidence based on a novel comprehensive dataset of legislative activity and 32 interviews with parliamentarians, ex-ministers, and other high ranking officials. Our findings contribute to explaining ambiguous evidence in the literature on the political economy of reform.

分阶段改革：政治合作框架，适用于黎巴嫩

分割如何影响改革方面的政治合作？我们发展出一种理论来解释立法产出随时间和政策领域的变化。我们将展示改革项目的性质如何确定细分化在多大程度上影响改革方面的政治合作。我们将我们的框架应用于黎巴嫩案件，并基于新的立法活动综合数据集以及对议员，前部长和其他高级官员的32次采访，提出了混合方法的证据。我们的发现有助于解释有关改革政治经济学的文献中的模棱两可证据。
