Book excerpt: Based on a highly interdisciplinary theoretical framework, Tobias Schroedler provides a comprehensive picture of the value of language skills within the Irish economy. The author manages to present and merge theories from economics, business studies, sociology, and applied linguistics making this an innovative and valuable contribution to the growing field of research on the value of multilingualism and languages. The first of two datasets presented in the book provides a macroeconomic quantification on the economic performance of four different global language communities. The second dataset consists of an expert interview study on the matter. Based on the data analysis, the author derives recommendations for economically beneficial language education policy making.
