THE DETERMINANTS OF HUMAN CAPITAL FORMATION DURING THE EARLY YEARS OF LIFE: THEORY, MEASUREMENT, AND POLICIES
讨论了早期人力资本积累的研究议程，重点关注发展中国家，提出了一个概念框架来组织研究，并以随机对照试验为例展示了该框架的应用。
In this paper, I discuss a research agenda on the study of human capital accumulation in the early years, with a particular focus on developing countries. I discuss several methodological issues, from the use of structural models, to the importance of measurement and the development of new measurement tools. I present a conceptual framework that can be used to frame the study of human capital accumulation and view the current challenges and gaps in knowledge within such an organizing structure. I provide an example of the use of such a framework to interpret the evidence on the impacts of an early years intervention based on randomized controlled trial.
