Disguised Pollution : Industrial Activities in the Dark
In this study we investigate disguised pollution by industrial firms in China. We find that sulfur dioxide (SO2) readings increase by 10.8% in monitoring stations after sunset in high factory density areas, controlling for station-year and city-hour fixed effects. Physical inspections by the Ministry of Environmental Protection can only temporarily reduce disguised pollution, suggesting that reliance on physical inspections to enforce regulations is ineffective if firms can shift increased production activities to non-daylight hours. We show that direct monitoring, as is done with some large polluters in China, can prevent this and should be cost-effective to extend to all industrial polluters
