内容摘要：We study the 2013 seachange in pollution information availability when China rolled out a nationalpollution monitoring network in three waves to disclose real-time air qualityin more than 300 cities. We document a surge in media mention as well ascitizens’ interest in pollution topics. We then show how short- and long-runavoidance behavior change with better information. First, we use detailedpoint-of-sale (POS) credit and debit card transaction data to show that highoutdoor pollution suppresses daily purchase trips, much more so when the publicgained access to information. Second, the spatial variation in pollution levelseither across cities or across communities within a city is better reflected inhousing prices post disclosure. Finally, we use national disease surveillancedata to show that the correspondence between air pollution exposure andmortality rate weakens post disclosure. The estimates from our analysis suggestthat the information program has reduced premature deaths attributable to airpollution exposure by nearly 9%.
