我们研究了广告代理行业解体和增长过程中的知识溢出和外部性。一个简单的高需求、低工资和与相关产业集群相关的外部性模型可以解释广告公司就业在各州之间的分散。其他因素影响了各州的行业增长率。与雅各布斯和波特一致，但与马歇尔、阿罗和罗默相反，竞争而不是专业化促进了增长。根据Porter（1990）的研究，增长随着买方集群规模的增加而增加。多样性对生长没有影响。尽管电信和交通的进步缩短了有效距离，但位置仍然很重要。
We investigate knowledge spillovers and externalities in the disagglomeration and growth of the advertising-agency industry. A simple model of high demand, low wages, and externalities associated with clusters of related industries can explain the dispersion of advertising agency employment across states. Other factors affected the industry growth rate within states. Consistent with Jacobs and Porter but contrary to Marshall, Arrow, and Romer, competition, but not specialization, enhanced growth. In accord with Porter (1990), growth increased with buyer cluster size. Diversity had no effect on growth. Despite improvements in telecommunications and transportation reducing effective distances, location still matters.
