How states of origin regulate the rights, obligations, and services they extend to their emigrants has remained mostly in the shadows of migration policy research. We have tackled this gap in the literature by advancing the Emigrant Policies Index (EMIX), which was designed for comparing the degree of adoption of emigrant policies – also called ‘diaspora-engagement policies’ – across countries in a whole region and, with the update provided in this paper, for the first time in a longitudinal direction. Having previously introduced the EMIX in a synchronic frame, this article presents its scores for 14 countries of Latin America and the Caribbean in 2015 and 2017. This effort already shows that some emigrant policies (e.g. citizenship policies) endure more than others (e.g. social policies). These suggestive findings support the need to compile not only cross-national, but also longitudinal datasets on these policies.

侨民参与政策是否持久？移民政策指数 (EMIX) 更新至 2017 年

原籍国如何规范他们扩展到移民的权利、义务和服务，大多仍处于移民政策研究的阴影中。我们通过推进移民政策指数 (EMIX) 解决了文献中的这一差距，该指数旨在比较整个地区各国对移民政策（也称为“侨民参与政策”）的采用程度，并与本文中提供的更新，首次在纵向方向上进行。之前在同步框架中介绍了 EMIX，本文展示了 2015 年和 2017 年拉丁美洲和加勒比地区 14 个国家的得分。 这一努力已经表明，一些移民政策（例如公民政策）比其他政策（例如社会政策）更持久）。
