本文以曼哈顿的广告代理业为研究对象，旨在推断空间邻近的广告代理商之间的网络效益。我们使用经济普查数据，使我们能够在地理细节的精细水平上区分位置，从而推断出拥有更多邻近广告公司的邻居对生产力的强烈影响。密切关注识别问题，我们发现，然而，有非常迅速的空间衰减的好处，更近的邻居，即使在近距离的南部曼哈顿，一个新的发现的文献。这表明，类似商业机构的高密度对于提高大城市工业的当地生产力非常重要，而信息共享在大城市中发挥着关键作用。我们的研究结果表明，更多的近邻的好处主要是资本化的租金，而不是工资，挑战现有的文献，估计工资方程单独推断集聚效益。
This paper studies the advertising agency industry in Manhattan to infer networking benefits among agencies in close spatial proximity. We use economic census data that allow us to distinguish locations at a fine level of geographic detail, so as to infer the strong effect on productivity of having more near advertising agency neighbours. Paying close attention to identification issues, we show, however, that there is extremely rapid spatial decay in the benefits of more near neighbours, even in the close quarters of southern Manhattan, a finding that is new to the literature. This suggests that high density of similar commercial establishments is important in enhancing local productivity for those industries found in large cities, where information sharing plays a critical role. Our results indicate that the benefits of more near neighbours are largely capitalized into rents rather than wages, challenging an existing literature, which estimates wage equations alone to infer agglomeration benefits.
