Exploring consistency between stated and revealed preferences for the plastic bag ban policy in Chile.

• Plastic pollution is a global concern with adverse consequences on the environment. • Ban policies has recently drawn the attention of governments to regulate plastic. • We analyze consistency of stated and revealed preferences for plastic bag ban. • Inconsistencies reduced with regulation experience and pro-environmental behavior. This paper exploits individual-level data before the implementation of a national policy to understand the factors driving avoidance of plastic consumption and explore potential inconsistencies between revealed and stated preferences for a plastic bag ban policy. We estimate a bivariate ordered probit model that allows us to account for a potential correlation between these types of preferences. The data reveals that while 71% of respondents take a reusable bag for shopping, only 58% of the sample state to strongly agree with prohibiting plastic bags. We find that gender, age, environmental concerns, environmental efforts, participation in environmental causes and pro-environmental behavior determine avoidance of plastic consumption, but no effects are found for being in favor of the prohibition. We also find inconsistencies decrease for individuals demonstrating higher pro-environmental behavior in related domains. This indicates waste management policies may benefit from local grounded knowledge from related environmental initiatives. [ABSTRACT FROM AUTHOR]
