Urban Air Quality

9311881亨德森本研究的目的是分析1970年至1987年之间空气质量管制对（1）各种制造业的城市位置和生产率的影响，以及对（2）大都市地区和中心城市与郊区之间空气质量的影响。 1987年关于地点、就业增长和生产率的方程将根据当前和历史的工业环境和监管情况直接估算，考虑到不确定性、审查和选择性等问题。 虽然对未达标地区的监管可能导致工业活动在大都市地区的重新分配，并相应地提高和降低生产力，但未达标地区环境质量的改善通过降低工资对工业产生了积极影响。 Hedonic工资函数捕捉空气质量和工资之间的联系将被估计，占的问题的一致性和联合工资地租的决定。 这个项目很重要，因为它将揭示空气污染法规的经济效应和对城市空气质量的影响。 ***

9311881 Henderson The purpose of this research is to analyze the impact of air quality regulation between 1970 and 1987 on (1) urban location and productivity for a variety of manufacturing industries, and on (2) air quality across metropolitan areas and between central cities and suburbs. Equations for 1987 concerning location, employment growth, and productivity will be estimated directly, based upon current and historical industrial environments and regulation, accounting for issues of simultaneity, censoring, and selectivity. While regulation in non-attainment areas may have resulted in a reallocation of industrial activity across metropolitan areas, with corresponding productivity gains and losses, improved environmental quality in non-attainment areas has positive impact for industry through lower wages. Hedonic wage functions capturing the link between air quality and wages will be estimated, accounting for issues of simultaneity and joint wage-land rent determination. This project is important because it will shed new light on the economic effects and impact on urban air quality of air pollution regulations. ***
