Abstract
The study examines whether prior migration experience—that includes various social and economic interactions between migrants of the same nationality, albeit across different ethnic groups in the foreign country of employment, affects the return migrants’ preferences and beliefs in their home country about individuals of their own as well as of different ethnic groups. This project will use randomized controlled trials based on experiential priming to evaluate the changes in returnees’ in-group and out-group behaviors using different types of in-the-lab, incentivized economic decision-making games.

Experimental Details

Interventions

Intervention(s)
The intervention includes experiential priming that asks questions about the subject’s experience as a migrant, in particular his interactions with people of their own and the other ethnic group. The neutral prime asks parallel questions about the subject’s experience at school in Nepal.

Experimental Design

Experimental Design
To test the effects of prior migration experience on in-group bias, we employ a 2x2 between-subjects design. Along one dimension, we vary whether the study subject is matched with another person from his own ethnic group or from the other ethnic group. Along the other dimension, we vary whether the subject receives a “migrancy prime” or a “neutral prime”.
