The Causes and Consequences of Development Clusters: State Capacity, Peace, and Income*
探讨了人均收入、国家能力与政治暴力缺失这三个发展维度在国家层面的相关性，分析了共同驱动因素和互补性两种解释，并提出了初步政策启示和未来研究方向。
Three important aspects of development—per capita income, state capabilities, and (the absence of) political violence—are correlated with each other at the country level. This article discusses the causes of such development clusters and highlights two explanations: common economic, political, and social drivers and complementarities (two-way positive feedbacks). It also draws out preliminary policy implications of these patterns of development and proposes topics for further research.
