摘要

This paper examines how air pollution affects consumption decisions through income and substitution channels by linking daily air pollution data with monthly records of individual consumption and labor productivity. Exploiting a quasi-experimental setting in a prison in Shenzhen City, China, we find that a 10-unit increase in the daily air pollution index reduces monthly consumption by 3.6%, with 78% of the effect explained by the income channel. The impact is heterogeneous across demographic groups and pollution levels. By jointly analyzing productivity and consumption responses, the paper contributes to a growing literature on the behavioral and economic consequences of environmental exposure.
