The Human Capital Stock: A Generalized Approach
重新审视了跨国收入差异研究中人力资本测量的传统方法，发现传统核算只是人力资本差异的理论下限，而广义核算可能完全解释富国与穷国间的收入差距。
This paper reconsiders the traditional approach to human capital measurement in the study of cross-country income differences. Within a broader class of neoclassical human capital aggregators, traditional accounting is found to be a theoretical lower bound on human capital differences across economies. Implementing a generalized accounting empirically illustrates the possibility that capital variation may now account (even fully) for the large income variation between rich and poor countries. These findings reject the constraints on human capital variation that traditional accounting has imposed.
