我们开发了一个城市增长模型，其中人力资本溢出促进了异质性城市的创业和学习。现有居民通过规划法规限制城市扩张，这样通勤和住房成本就不会超过生产力收益。该模型建立在强大的微观基础上，符合城市和整个经济层面的关键规律，并产生新的预测，我们为其提供证据。它可以依靠几个参数进行量化，为估计主要参数提供基础，并且在其机制方面保持透明。我们考察了各种反事实，以定量评估城市对经济增长和总收入的影响。
We develop an urban growth model where human capital spillovers foster entrepreneurship and learning in heterogenous cities. Incumbent residents limit city expansion through planning regulations so that commuting and housing costs do not outweigh productivity gains. The model builds on strong microfoundations, matches key regularities at the city and economy-wide levels, and generates novel predictions for which we provide evidence. It can be quantified relying on few parameters, provides a basis to estimate the main ones, and remains transparent regarding its mechanisms. We examine various counterfactuals to assess quantitatively the effect of cities on economic growth and aggregate income.
