Paul Romer: Ideas, Nonrivalry, and Endogenous Growth
回顾了2018年诺贝尔经济学奖得主保罗·罗默的获奖贡献，他发展了内生技术变革理论，强调追求利润的企业家和研究者对创意的探索是经济增长的核心，并指出创意的非竞争性是生活水平长期提升的根本原因。
Abstract In 2018, Paul Romer and William Nordhaus shared the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. Romer was recognized “for integrating technological innovations into long‐run macroeconomic analysis”. This article reviews his prize‐winning contributions. Romer, together with others, rejuvenated the field of economic growth. He developed the theory of endogenous technological change, in which the search for new ideas by profit‐maximizing entrepreneurs and researchers is at the heart of economic growth. Underlying this theory, he pinpointed that the nonrivalry of ideas is ultimately responsible for the rise in living standards over time.
