Este caso indica que no alcanza con facilitar el papel: quedarse depende de oportunidades reales de carrera, financiamiento y estabilidad. Para la Argentina, que forma científicos muy valorados y después pierde muchos ante el exterior, la lección es que el problema no se resuelve solo con trámites. La pregunta de fondo es qué hace falta para que alguien decida quedarse.","quienFirma":"EconStor (investigación sobre universidades francesas)","confianza":"revisado","consulta":null},"sello":{"hash":"b143c80b7b83685f6c60044a7026c7ca2709a9c1e6f93185cca784c5a342afc8","sello":"2e75d4f70e85f1054033cc88871332e3ac243dc38f527d79f93b2f5f61db98f3","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6574471,"aleatorio":"8dc65bda024d9b15bc5015dca7a625bd58abcd79898d9e649dd88c7b09d4609e","tiempo":"2026-10-22T10:32:30.000Z"},"nist":{"cadena":2,"pulso":1994441,"salida":"917B00588BBAF41DD8C461E7D93EA47DC73C00983776285722380061C2505D68D1C49D178A1E9E1A422EEA35DB6367141AB79828DD0F9592CE1805F752B02469","tiempo":"2026-10-22T10:32:00.000Z"},"noAntes":"2026-10-22T10:32:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 22 10:32:40 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Researcher Visas and the Retention of Foreign PhD Graduates: Evidence from France","descripcion":"We investigate the effects of the introduction of the first visa scheme for foreign researchers in France (the carte de sejour \"scientifique-chercheur\") introduced in 1998 on the post-graduation stay rates of foreign-born doctoral graduates at French universities. We build a novel dataset containing all doctoral graduates in STEM disciplines from 1992 to 2002 and their scientific publications. We distinguish between non-EU graduates, to whom the carte de sejour applied, and French or other EU graduates, to whom it did not using a name-based ethnicity analysis. We then assess short- and long-term career stay outcomes using graduates’ post-PhD publication activity and affiliation locations, and identify those who later become doctoral supervisors themselves. Using a difference-in-differences estimation strategy with repeated cross-sectional cohorts of graduates, we find no meaningful effec","pubDate":"2026-10-16T16:24:31Z","url":"https://hdl.handle.net/10419/344145"},"indexado":"2026-10-22T10:32:02.032Z"}}
