摘要

拥堵是城市集聚中最具挑战性的问题之一。拥堵成本高于社会最优水平，设计最优政策所需的关键参数需要更多信息。本文利用纽约市出租汽车供应量的外生性减少来估算其对出行速度的影响，并记录对其他交通方式的替代模式。出租车减少 9.1% 会使出行速度每英里提高 0.45 分钟，即提高 7.2%。随着等待时间的增加和人们转向其他交通方式，提高速度所带来的消费者剩余收益也随之减少。

Stuck in traffic: Measuring congestion externalities with negative supply shocks

Congestion is one of the most challenging issues of urban agglomeration. Congestion costs are higher than socially optimal levels, and more information is needed about the key parameters required to design optimal policies. This paper exploits an exogenous reduction in for-hire vehicle supply in New York City to estimate their effect on travel speed and document substitution patterns to other transportation modes. A 9.1 percent decrease in taxis is associated with increased travel speed by 0.45 min per mile, a 7.2 percent increase. Consumer surplus gains from increased speed fade as waiting times increase and people switch to other transportation modes.

期刊介绍： Regional Science and Urban Economics facilitates and encourages high-quality scholarship on important issues in regional and urban economics. It publishes significant contributions that are theoretical or empirical, positive or normative. It solicits original papers with a spatial dimension that can be of interest to economists. Empirical papers studying causal mechanisms are expected to propose a convincing identification strategy.
