Abstract

We present a two-area endogenous growth model where abstract knowledge flows at no cost across space but tacit knowledge arises from the interaction among researchers and is hampered by distance. Digital communication reduces this “cost of distance” and reinforces productive specialization, leading to an increase in the system-wide growth rate but at the cost of more inequality within and across areas. These results are consistent with evidences on the rise in the concentration of innovative activities, income inequality, and skills and income divergence across US urban areas.

两个城市的故事：交流、创新与分歧

我们提出了一个两地区内生增长模型，在这个模型中，抽象知识的跨空间流动不需要成本，但隐性知识产生于研究人员之间的互动，并受到距离的阻碍。数字通信降低了这种 "距离成本"，加强了生产专业化，从而提高了整个系统的增长率，但代价是地区内部和地区之间的不平等加剧。这些结果与美国城市地区创新活动集中度上升、收入不平等以及技能和收入分化的证据是一致的。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
