Idea Flows and Economic Growth
回顾了关于学习的新理论，强调学习者或创新者与其知识环境的不同角色，并应用于个人收入生命周期、组织内知识扩散、企业动态以及贸易在创意扩散中的作用。
We review new theories of learning that posit specific, distinct roles for the learner or innovator and their intellectual environment. We consider applications to the dynamics of individual earnings over the life cycle, the diffusion of knowledge within an organization and firm dynamics, and the role of trade in the diffusion of ideas.
