How Languages Build Economies:

  • Employees who speak a second language often earn more than monolinguals.
  • The ability to speak a second language often positively affects earnings both directly and indirectly through educational achievement, a wider range of opportunities for involvement in local and global markets, and by signalling enhanced communicative and cognitive abilities and skills to potential employers.
  • Second-language skills afford individuals greater mobility in both local and international markets and allow them to serve a wider range of clientele.
  • Second-language skills are often highly valued and expected by potential employers.
  • Second-language skills have large-scale economic benefits, as they make businesses more competitive in the global economy and boost international trade.

The above statements come from the Literature on the Impact of Second-Language Learning (2017).
