On the Performance of the U.S. Transportation System: Caution Ahead
评估美国交通系统的表现，通过分析公共与私人提供的最优组合，发现政府政策损害了交通系统，建议改善公共提供或扩大私人部门角色。
Transportation is a vital sector of the U.S. economy based on consumers', firms', and government's enormous expenditures in money and time and on its effect on virtually all other sectors in the economy. I assess the performance of the transportation system and consider how it could be improved by analyzing whether the United States has the optimal mix of public and private provision. The empirical evidence indicates that our hugely important transportation system has been compromised by various government policies and the significant welfare costs motivate either vastly improving public provision or expanding the role of the private sector.
