This paper explores the impact of new universities established in the USA between 1931 and 1980 on population density, GDP and market size measured from 1930 to 2010. The analysis is based on differences in differences on counties selected through propensity score matching, as well as an instrumental variable approach. The evidence suggests that counties hosting a university for the first time grew by between 1% and 3% annually on top of the general trends of population density and GDP growth, and that this effect expanded to neighboring counties. Controlling for research intensity and interstate road infrastructure shows that the potential gains from these new universities were severely constrained by the ease of access, which eventually resulted in higher congestion costs. These results point to a situation where new universities create spillover effects that eventually fade away if not accompanied by additional investments.

大学会产生空间溢出吗?1930 年至 2010 年美国各县的证据

本文探讨了 1931 年至 1980 年间在美国建立的新大学对 1930 年至 2010 年测量的人口密度、GDP 和市场规模的影响。该分析基于通过倾向得分匹配选择的县的差异,以及工具变量法。证据表明,除了人口密度和 GDP 增长的总体趋势之外,首次举办大学的县每年增长 1% 至 3%,并且这种影响扩大到邻近县。控制研究强度和州际公路基础设施表明,这些新大学的潜在收益受到交通便利的严重限制,最终导致更高的拥堵成本。
