A Contribution to the Empirics of Economic Growth
检验索洛增长模型能否解释各国生活水平的差异，发现加入人力资本的扩展索洛模型能很好拟合跨国数据，并验证了在控制人口增长和资本积累后，各国生活水平会以模型预测的速度收敛。
This paper examines whether the Solow growth model is consistent with the international variation in the standard of living. It shows that an augmented Solow model that includes accumulation of human as well as physical capital provides an excellent description of the cross-country data. The paper also examines the implications of the Solow model for convergence in standards of living, that is, for whether poor countries tend to grow faster than rich countries. The evidence indicates that, holding population growth and capital accumulation constant, countries converge at about the rate the augmented Solow model predicts.
