Migrant Remittances and Information Flows: Evidence from a Field Experiment*

Do information flows matter for remittance behavior? We design and implement a randomized control trial to quantitatively assess the role of communication between migrants and their contacts abroad on the extent and value of remittance flows. In the experiment, a random sample of 1,500 migrants residing in Ireland was offered the possibility of contacting their networks outside the host country for free over a varying number of months. We find a sizable, positive impact of our intervention on the value of migrant remittances sent. Our results exclude that the remittance effect we identify is a simple substitution effect. Instead, our analysis points to this effect being a likely result of improved information via factors such as better migrant control over remittance use, enhanced trust in remittance channels due to experience sharing, or increased remittance recipients’ social pressure on migrants.

Associativismo: A ação das associações no desenvolvimento do município de Castelo Branco

O presente estudo aborda questões como a democracia, participativa e representativa, governança, capital social e associativismo. O seu objetivo é o de perceber de que forma o associativismo, enquanto elemento de concentração de capital social, e governança enquanto mecanismo de ações participadas, podem levar ao desenvolvimento sustentável, e a uma melhor implementação da democracia. De que forma o associativismo influenciou o desenvolvimento, neste caso em particular, do município de Castelo Branco. Com base nesse objetivo foram realizadas entrevistas a várias associações do município e ao poder local, nomeadamente a três Juntas de Freguesia e à Câmara Municipal para tentar perceber se existe um modelo de governança implementado no município. Se as associações enquanto espaços de produção de capital social têm ou não uma palavra, um espaço de opinião, no que refere ao desenvolvimento da cidade nos diversos campos, social, económico, urbano, etc. Tentar compreender os motivos que levaram à criação dessas associações, sejam elas comerciais, empresariais ou recreativas, e qual o seu contributo para o processo de desenvolvimento local, apurando não só os seus níveis de atividade, mas também o seu contributo para o desenvolvimento local e com que intuito surgiram, uma vez que a participação nas associações, a um nível individual, pode ser visto como um incentivo à identificação e seleção de respostas a problemas pessoais, que ao serem transpostos para a esfera pública, os problemas vividos pelos indivíduos na esfera privada, incentivam a participação coletiva numa ação organizada visando o bem comum e a resolução de problemas de ordem social.

Assessing the role of social networks on migrant labor market outcomes: Evidence from a representative immigrant survey

What role do social networks play in determining migrant labor market outcomes? We examine this question using data from a random sample of 1500 immigrants living in Ireland. We propose a theoretical model formally predicting that immigrants with more contacts have additional access to job offers, and are therefore better able to become employed and choose higher paid jobs. Our empirical analysis confirms these findings, while focusing more generally on the relationship between migrants’ social networks and a variety of labor market outcomes (namely wages, employment, occupational choice and job security), contrary to the literature. We find evidence that having one more contact in the network is associated with an increase of 11pp in the probability of being employed and with an increase of about 100 euros in the average salary. However, our data is not suggestive of a network size effect on occupational choice and job security. Our findings are robust to sample selection and other endogeneity concerns.
