本文考察了1960 - 2000年间城市公路建设与各行业工作和工人居住地分散的关系。据估计，高速公路引起的居住区的分散程度远远大于工作的分散程度.这些处理效果的识别依赖于联邦公路系统规划部分的外生变化，以及由于这些城市的相对位置而导致的城市间公路数量的变化。每一条放射状的高速公路都取代了大约16%的中心城市工作人口，但只有6%的工作转移到郊区。这些估计在整个行业中相当一致。这些结果支持的想法，当地的溢出效应仍然是一个重要的激励. RMS集群空间，即使在面对运输成本的降低。� 初步和不完整。未经允许，请勿引用。
This paper investigates the relationships between urban highway construction and the de- centralization of jobs and workers'residential locations by industry between 1960 and 2000. Estimates indicate that highways cause signi…cantly greater amounts of residential than job de- centralization. Identi…cation of these treatment eects relies on exogenous variation available from planned portions of the federal highway system and variation across cities in the number of highways received due to these cities'relative locations. Each radial highway displaced an estimated 16 percent of the central city working population but only 6 percent of the jobs to the suburbs. These estimates are fairly consistent across industry. These results support the idea that local spillovers remain an important incentive for …rms to to cluster spatially, even in the face of transportation cost reductions. � Preliminary and Incomplete.
