governments establish the optimal city size when production processes involve environmental pollution. Our analysis delivers two … key insights. First, if an optimal scheme to regulate environmental pollution is implemented, cities chosen by local … governments are never too large. They are too small if pollution is purely global, but at the optimal size, if pollution is purely …

, environmental regulation, productivity, and consumer preferences have contributed to these reductions in pollution emissions. We … estimate the model's key parameters using administrative data on plant-level production and pollution decisions. We then … pollution changes. Finally, we compare the model-driven decomposition to a statistical decomposition. The model and data suggest …

Using precise measures of each worker's daily output linked to daily measures of pollution and meteorology, we find …We investigate the effect of pollution on worker productivity in the service sector by focusing on two call centers in … that higher levels of air pollution decrease worker productivity by reducing the number of calls that workers complete each …
