Abstract
Appeals to group identities can increase contributions to public goods and induce pro-social behavior. But humans have inescapably plural identities. Therefore politicians, companies and NGOs that want to make use of group identities in public campaigns or in private messages face a tough choice between the multiple identities of their audience in any particular context. In 2014, the Indian Prime Minister Narendra Modi launched the Clean India Campaign which aims at changing social norms for littering and open-defecation. This project will test whether appeals to group identities can reduce littering in a field experiment in Bengaluru, India, and whether local identities or the national identiy are more effective.

Experimental Design

Experimental Design
The field experiment will be conducted in public locations in Bangalore with a high rate of littering: at smoking shops. In India, smoking in public is forbidden by law, but socially accepted around small smoking shops. Most shops sell individual cigarettes to smokers alongside the infamous masala tea, served in one way paper cups.

Posters containing identity-based messages and anti-littering norms are pinned in the smoking area. An appeal to national identity is tested against an appeal to local community identity and control.

A survey is conducted after subjects left the smoking area. The survey measures the senses of identification with the identities tested alongside socio-demographic characteristics. The individual survey data is linked to the individual observational data, which provides for a very rich data set.
