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.

Planeamento da alta : impacto nos indicadores de desempenho hospitalar

RESUMO - Planeamento da Alta: Impacto nos Indicadores de Desempenho Hospitalar O problema do presente trabalho reside na percentagem de hospitais do SNS que não tem um processo de planeamento de alta standartizado. Norteada pela questão de investigação: Qual o impacto do Planeamento das Altas nos indicadores de desempenho dos hospitais do SNS?; pelas hipóteses de que os hospitais com um processo de Planeamento da Alta standartizado têm uma Taxa de Reinternamento e uma Demora Média menor; e pelo objetivo geral: Conhecer o impacto do planeamento da alta standartizado nos indicadores de desempenho dos hospitais do SNS, enveredou-se pelo paradigma quantitativo e foi realizada uma análise comparativa dos indicadores de desempenho de dois grupos hospitalares. Estudou-se uma amostra da população acessível, constituída por 57 estabelecimentos hospitalares do SNS e destes foram criados dois grupos de hospitais, que diferiam no facto de ter um processo de planeamento de alta standartizado. No final obteve-se uma amostra, não probabilística, de 12 hospitais, seis que possuíam um processo standartizado e os outros seis não. A recolha de dados foi efetuada através dos sítios da ACSS, DGS e das entidades hospitalares. Os dados foram tratados através da estatística descritiva e indutiva, com recurso a programas informáticos. Da análise emergiram como principais resultados: A existência de um processo de planeamento de alta hospitalar standartizado não tem um impacto significativo nos indicadores de desempenho hospitalar, nomeadamente na redução das Taxas de Reinternamento e da Demora Média hospitalar.

An existence result for discontinuous games

We introduce a notion of upper semicontinuity, weak upper semicontinuity, and show that it, together with a weak form of payoff security, is enough to guarantee the existence of Nash equilibria in compact, quasiconcave normal form games. We show that our result generalizes the pure strategy existence theorem of Dasgupta and Maskin (1986) and that it is neither implied nor does it imply the existence theorems of Baye, Tian, and Zhou (1993) and Reny (1999). Furthermore, we show that an equilibrium may fail to exist when, while maintaining weak payoff security, weak upper semicontinuity is weakened to reciprocal upper semicontinuity.
