本文研究公共交通政策对城市污染的影响。它采用包含住宅选择和模式选择的定量均衡模型。污染来自通勤和住宅能源的使用。模型参数经过校准以复制美国大都市区的关键变量。在反事实中，我研究免费公共交通与不断增加的交通速度如何影响平衡。在基线模拟中，总污染下降了 0.4%，因为交通排放量的减少被住宅排放量的增加部分抵消。第二个反事实比较了有公共交通的城市和没有公共交通的城市。这项巨大的投资使污染减少了1.7%。当工作分散时，第一个反事实排放量下降 0.5%，第二个反事实排放量下降 3%。
This paper studies the effect of public transport policies on urban pollution. It uses a quantitative equilibrium model with residential choice and mode choice. Pollution comes from commuting and residential energy use. The model parameters are calibrated to replicate key variables for American metropolitan areas. In the counterfactual, I study how free public transport coupled with increasing transit speed affects the equilibrium. In the baseline simulation, total pollution falls by 0.4%, as decreasing emissions from transport are partly offset by rising residential emissions. A second counterfactual compares a city with and without public transit. This large investment decreases pollution by 1.7%. When jobs are decentralized, emissions fall by 0.5% in the first and by 3% in the second counterfactual.
