Field Abstract | Before We run a survey experiment to investigate the effectiveness of social norms in promoting the support to migrants. We design an intervention that presents different social norms regarding other's behaviour and attitude towards migrants and we test their influence on behavioural outcomes with respect to a control where social information is not provided. We explore the channel(s) through which a manipulation of social information is successful in affecting behaviour. | After The number of migrants moving from one country to another is bound to increase, and a considerable fraction of these flows will try to access the European countries. At the same time, public opinion towards immigration is often negative. A supportive public approach has many advantages, as it can facilitate an efficient management of the migration flows and improve the integration of migrants in our societies. Building on a theoretical model, we study a set of experimental treatments aimed at promoting support to immigration through a mechanism based on social norms. Our intervention consists of presenting a favourable social norm prevailing among the members of an "ingroup" (the natives) and test its effectiveness in reducing the social distance between a subject belonging to the ingroup and the "outgroup" (the migrants). Receiving a favourable social norm is expected to deliver a clear sign that peers of the ingroup are not against migrants, ultimately affecting behaviour. |

Field Experimental Design (Public) | Before We plan to conduct an incentivized survey and recruit British participants through the online platform Prolific Academic. Respondents in the treatment groups will receive information on the social norm, namely on what other respondents did before them in terms of donation to a charity operating in favour of migrants. Moreover, to understand to what extent the social norm is effective in changing donations per se, or due to its capability to convey information on the ingroup attitude towards the outgroup, we will also design a treatment where we directly provide information on the ingroup (favourable) attitude towards the outgroup. In the Control treatment respondentswill not receive any information on previous respondents’ behaviour or attitude. | After We plan to conduct an incentivized survey and recruit Italian participants. We will employ a survey firm to collect data for a representative sample of respondents with respect to socio-demographic characteristics. Respondents in the treatment groups will receive information on the social norm, namely on what other respondents did before them in terms of donation to a charity operating in favour of migrants. Moreover, to understand to what extent the social norm is effective in changing donations per se, or due to its capability to convey information on the ingroup attitude towards the outgroup, we will also design a treatment where we directly provide information on the ingroup (favourable) attitude towards the outgroup. In the Control treatment respondentswill not receive any information on previous respondents’ behaviour or attitude. |
