This paper investigates the impact of environmental awareness on local fiscal revenue in China. We exploit the unexpected release of the environmental documentary Under the Dome in early 2015 as an exogenous shock on residents preferences. The generalized difference-in-difference estimation shows that on average, a one standard deviation increase in the exposure to the documentary would reduce the government land sale revenue by 21.45 billion CNY. Consistent with the “vote with feet” mechanism in Tiebout model, after the release of this film, residents increase awareness of air pollution and express higher mobility intention. Local government also raises environmental investment as a response. This indicates the value of market in constraining the behavior of local governments in authoritarian states.
