Subways and Urban Air Pollution with Matthew Turner
Tuesday, February 06, 2018 at 12:30pm to 2:00pm
The MIT-CFC seminar series, debuting this spring semester, is a monthly or bimonthly gathering of scholars from a variety of fields interested in urban China research. We will invite distinguished scholars to share their research and insights on a wide range of topics that could provoke discussions and exchange of ideas that matter for China’s urbanization and sustainable growth.
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.
