Long-Run Policy Analysis and Long-Run Growth
构建了一类模型，说明各国经济增长率的巨大差异可能源于政府政策的不同，这些差异还会激励劳动力从慢增长国向快增长国迁移。模型中的增长是内生的，即使没有规模报酬递增，因为存在一个核心资本品，其生产不需要不可积累要素的直接或间接贡献。
The wide cross-country disparity in rates of economic growth is the most puzzling feature of the development process. This paper describes a class of models in which this heterogeneity in growth experiences can be the result of cross-country differences in government policy. These differences can also create incentives for labor migration from slow-growing to fast-growing countries. In the models considered, growth is endogenous, despite the absence of increasing returns, because there is a "core" of capital goods that can be produced without the direct or indirect contribution of factors that cannot be accumulated, such as land.
