As an engine of economic growth as well as in the distribution of income that is the fruits of economic growth, the role of human capital accumulation has been increasing. Hence, constructing a growth model with human and physical capital accumulation, we have provided a policy rule that ensures the optimal resource allocation between human and physical capital. Also, we have pointed out that a skill-premium puzzle, which is characterized by an increase in income inequality withincreased skill-labor supply, takes place when the cost of human capital investment (or skill-acquisition cost) changes with technical progress. In addition, it is shown that an increase in uncertainty on human capital investment costs tends to fix inequality over generations.

作为经济增长的引擎，以及作为经济增长成果的收入分配，人力资本积累的作用越来越大。因此，通过构建人力资本和物质资本积累的增长模型，我们提供了保证人力资本和物质资本之间资源最优配置的政策规则。此外，我们还指出，当人力资本投资成本(或技能获取成本)随着技术进步而变化时，就会出现以收入不平等加剧和技能劳动力供给增加为特征的技能溢价之谜。此外，研究表明，人力资本投资成本不确定性的增加往往会解决世代之间的不平等问题。
