Beschreibung:
We estimate the acute effect of air pollution on cognitive performance and how the effect varies with training and task proficiency using data of over 25,000 individuals and 927,000 plays of a popular online arithmetic training game. To isolate exogenous pollution fluctuation, we interact spatial variation in NOx emissions with thermal inversion episodes. This exogenous variation negatively affects cognitive performance of proficient players, but not of beginners. Instrumenting NO2 pollution with the emissions × inversion interaction, we find that a 1 ppb concentration increase lowers the number of correct answers of proficient individuals by 0.5 and by 0.2 overall
