The Search for the Sources of Growth: Areas of Ignorance, Old and New
指出标准增长核算对增长来源的描述具有误导性，以美国为例说明有形资本积累、教育及研发对增长的贡献掩盖了技术进步的偏向性，强调需更深入理解资本积累与技术进步的相互作用。
Many economic historians, like most economists, depend on standard growth accounts to provide some quantitative description of the proximate sources of growth, but this is misleading. American growth experience illustrates the difficulty. The seeming major contribution of tangible capital accumulation to nineteenth-century growth was the consequence of scale-dependent and capital-using technological progress. The large twentieth-century contributions of education and R&D conceal technology's new intangible capital-using bias. Additionally, reverse forces run from capital accumulation to technological progress. Without a greater understanding of these interactions, our knowledge of even the proximate sources of growth is incomplete.
