From Physical to Human Capital Accumulation: Inequality and the Process of Development
构建了一个增长理论，解释在发展过程中物质资本积累如何被人力资本积累取代成为增长的主要引擎，并论证不平等对增长的影响在这一过程中发生了逆转。
This paper develops a growth theory that captures the replacement of physical capital accumulation by human capital accumulation as a prime engine of growth along the process of development. It argues that the positive impact of inequality on the growth process was reversed in this process. In early stages of the Industrial Revolution, when physical capital accumulation was the prime source of growth, inequality stimulated development by channelling resources towards individuals with a higher propensity to save. As human capital emerged as a growth engine, equality alleviated adverse effects of credit constraints on human capital accumulation, stimulating the growth process.
