美国州际公路系统的出现提供了一个有趣的实验，我用它来确定减少贸易壁垒对劳动力市场的影响。这条高速公路网的设计目的是连接城市和边境口岸，并为国防服务，作为一个意想不到的后果，它跨越了许多农村县。我发现这些县经历了贸易相关活动的增加，如卡车运输和零售。通过增加贸易，高速公路提高了技能丰富的县对熟练制造业工人的相对需求，并减少了其他地方的需求，这与赫克歇尔-奥林模型的预测一致。
The advent of the U.S. Interstate Highway System provides an interesting experiment, which I use to identify the labor market effects of reduced trade barriers. This highway network was designed to connect cities and border crossings and to serve national defense, and as an unintended consequence it crossed many rural counties. I find that these counties experienced an increase in trade-related activities, such as trucking and retail sales. By increasing trade, the highways raised the relative demand for skilled manufacturing workers in skill-abundant counties and reduced it elsewhere, consistent with the predictions of the Heckscher-Ohlin model.
