题目：air pollution and consumers’ avoidance behavior: evidence from high-frequency payment data in china
摘要：
this paper estimates the impact of air pollution on consumers’ offline consumption behavior using high-frequency, bankcard transaction-level payment data from china in 2015 and 2016. employing a panel regression approach with thermal inversion as the instrumental variable for daily local air pollution exposure, we find a statistically and economically significant, negative relationship between pollution exposure and consumer spending. on average, a 100 μg/m³ increase in daily pm2.5 concentration leads to a 14% reduction in daily offline consumer expenditures paid via bankcards. the adverse impacts are particularly pronounced for spending on deferrable goods, groceries, and daily life services; and consumers significantly reduce outdoor shopping activities—including travel distance to intra-city shopping venues—during periods of elevated pollution, consistent with avoidance behavior. older individuals, high-spending consumers, and holiday shoppers exhibit stronger response to pollution. our findings underscore the potential economic co-benefits, in terms of consumption, achievable through policies improving air quality.
