发布日期：2018-06-11 10:10 来源：大陆成人直播-成人直播中文
经济学讲座
时间：2018年6月11日（周一）14:00-15:30
地点：Zhifu Xuan Conference Room, NSD, PKU
北大国发院/中国经济研究中心致福轩会议室
主持人：席天扬
主讲人：Professor Matthew Turner, Brown University
题目：Subways and Urban Air Pollution
简介：
We investigate the relationship between the opening of a city’s subway network and its air quality. We find that particulate concentrations drop by 4% in a 10km radius disk surrounding a city center following a subway system opening. The effect is larger near the city center and persists over the longest time horizon that we can measure with our data, about eight years. We estimate that a new subway system provides an external mortality benefit of about $594m per year. Although available subway capital cost estimates are crude, the estimated external mortality effects represent a significant fraction of construction costs.
