Impact of local and national social norm information on respondents’ choices regarding waste sorting at household level

The aim of this paper is to analyze the impact of information on social norms on Poles’ declared preferences regarding sorting waste. The conducted experiment examines effects of information on local and national social norms, represented by the proportion of residents sorting waste at households, on respondents’ declared choices on sorting at household level. The experiment was conducted in three Polish cities: Cracow, Warsaw and Bialystok; experimental conditions were created by presenting differing local and national social norms. To answer research questions, a discrete choice experiment (DCE) was employed. The results may be applied to create policy based on behavioral scheme called green nudges. They also contribute considerably to understanding of the role of social norms while referring to different − geographically closer (city level) and further (national) − groups.
