在1960-2000年期间,每一条服务于美国大都市地区的新的放射状高速公路都使14%至16%的中心城市工作居民和4%至6%的工作岗位流失。模型校准结果表明,中心城市全要素生产率相对于中心城市就业相对于郊区就业的弹性在0.04到0.09之间,这意味着很大一部分集聚经济在郊区的空间尺度上运行。每增加一条高速公路,中心城市扣除通勤成本的收入最高可增加2.4%,住房成本最高可下降1.3%。在住房生产中,要素向土地的重新分配产生了新公路造成的人口分散的多元化。
Each new radial highway serving large U.S. metropolitan areas decentralized 14% to 16% of central city working residents and 4% to 6% of jobs in the 1960–2000 period. Model calibrations yield implied elasticities of central city total factor productivity to central city employment relative to suburban employment of 0.04 to 0.09, meaning a large fraction of agglomeration economies operates at submetropolitan-area spatial scales. Each additional highway causes central city income net of commuting costs to increase by up to 2.4% and housing cost to decline by up to 1.3%. Factor reallocation toward land in housing production generates the plurality of the population decentralization caused by new highways.
