在大而密集的城市环境中，公司和工人的生产率要高得多。有大量证据表明，这种集聚经济基于三种方法。第一，关于超越偶然或比较优势所能解释的生产集群。第二，工资和租金的空间格局。第三，生产力随城市环境的系统性变化。然而，需要更多地了解集聚经济的原因。我们有很好的通过共享和匹配聚集的模式，但对城市学习的理解不够深入。尽管最近取得了进展，但还需要更多的工作来区分不同的原因。
Firms and workers are much more productive in large and dense urban environments. There is substantial evidence of such agglomeration economies based on three approaches. First, on a clustering of production beyond what can be explained by chance or comparative advantage. Second, on spatial patterns in wages and rents. Third, on systematic variations in productivity with the urban environment. However, more needs to be learned about the causes of agglomeration economies. We have good models of agglomeration through sharing and matching, but not a deep enough understanding of learning in cities. Despite recent progress, more work is needed to distinguish empirically between alternative causes.
