A new study published in the Journal of the Association of Environmental and Resource Economists looks at the causal relationship between outdoor air pollution levels on nationwide university entry examination day and students’ cognitive performance in Brazil.

In “The Effects of Air Pollution on Students’ Cognitive Performance: Evidence from Brazilian University Entrance Tests,” authors Juliana Carneiro, Matthew A. Cole, and  Eric Strobl use Brazilian data on concentrations of ozone (O3) and particulate matter (PM10) and a data set of students’ scores to examine the impact of air pollution on academic performance in national examinations. The air pollution data focuses on Rio de Janeiro and São Paulo—Brazil’s most industrialized states—using air pollution and weather monitoring station data to build a unique data panel from 2015–17.
