Abstract: | Using monthly regional panel data on air quality and large retail store sales in Korea, we empirically examine the effect of air pollution on retail sales. We account for regional heterogeneity in air pollution and control for various macroeconomic and climatic factors that can affect retail sales. We also use the air quality indicator in the west coastal islands (affected by trans‐border pollution but uncorrelated with the economic activity in the mainland) as an instrumental variable. The estimation results show that, in general, 1 additional day of PM10 level higher than 80 μg/m3 reduces monthly retail sales by approximately 0.1 percent. Nonetheless, an adaptive pattern emerges over time, particularly when the level of air pollution in the previous month was severe. |
