Pricing Congestion to Increase Traffic: The Case of Bogotá
研究了2021年波哥大改革限行政策、允许付费豁免后，交通流量增加但整体福利提升，中产阶级获益远超高收入者损失，若扩展为全面道路收费则效益可翻五倍。
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.
