RT Generic T1 Intergroup contact and nation building: evidence from military service in Spain A1 Caceres Delpiano, Julio A1 De Moragas, Antoni Italo A1 Facchini, Gabriel A1 González, Ignacio A2 Universidad Carlos III de Madrid. Departamento de Economía, AB We study the long-term effects of intergroup contact on nation building by exploiting a national lottery that randomly allocated conscripts to different military areas across Spain. For men born in regions featuring a strong regional identity, we find that being assigned to military service in a region different from one's region of birth substantially increases self-identification as Spanish and reduces the likelihood of voting for a regionalist party. Moreover, in support of intergroup contact as the main mechanism behind these results, we find that movers are more likely to have friends from another region than nonmovers SN 2340-5031 YR 2020 FD 2020-11-30 LK https://hdl.handle.net/10016/31507 UL https://hdl.handle.net/10016/31507 LA eng NO Cáceres-Delpiano gratefully acknowledges financial support fromthe Spanish Ministry of Education (Grant ECO2009-11165 and ECO2019-00419-001), the Spanish Ministryof Economy and Competitiveness (MDM 2014-0431), and the Comunidad de Madrid MadEco-CM (S2015/HUM-3444).
