Background & Significance § Since 1970’s US Government mandated lower levels of air pollution » In order to protect public health § In the case of total suspended particles (TSPs) the Environmental Protection Agency (EPA) set maximum allowable concentrations every country is required to meet » TSPs widely thought to be most pernicious form of air pollution § Consensus on radically elevated concentration of TSPs and relationship with health » More contentious as it relates to lower levels of TSPs § In absence of randomized controlled trials, study used an event (1980-1982 recession) that caused sharp changes in TSPs across sites in narrow time frame to estimate impact on infant mortality rates Analysis compares changes in infant mortality rates across counties that had large decreases in TSPs levels with those with small or no pollution reduction Chay KY, Greenstone M. The impact of air pollution on infant mortality: evidence from geographic variation in pollution shocks induced by a recession. Quarterly Journal of Economics 2003; 1121-1167

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
