中文摘要

2021年9月,波哥大市对其单双号限行政策(Pico y Placa)实施了一项重大的市场化改革。此后,驾驶者可以选择缴纳每日拥堵费以豁免限行。我们发现,尽管这项改革增加了交通量,但总体上带来了福利收益:中等收入群体因如今更频繁地使用汽车而获得的福利收益,远远超过了较高收入群体因如今在交通拥堵中耗费更多时间而遭受的损失。此外,我们表明,如果波哥大将这项改革扩展为一套全面的道路收费方案,这些总体收益可能增至五倍,更不用说空气质量改善带来的额外收益。

Abstract

Abstract In September 2021, the city of Bogotá introduced a major market-based reform to its odd–even driving restriction, known as Pico y Placa. Since then, drivers have had the option to pay a daily congestion fee to be exempt from the restriction. We find that while the reform increased traffic, it brought overall benefits. The welfare gains of middle-income individuals, who now use their cars more often, far outweighed the losses experienced by their higher-income counterparts, who now spend more time in traffic. Additionally, we show that these overall benefits could quintuple if Bogotá were to expand the reform into a comprehensive road-pricing scheme, not to mention the extra gains in air quality.
