In between the common subdisciplines of economics like international or financial economics, lie many much smaller specializations, for example the economics of language. The term “economics of language“ is defined by François Grin, to be “the paradigm of mainstream theoretical economics and uses the concepts and tools of economics in the study of relationships featuring linguistic variables, it focuses principally, but non exclusively, on those relationships in which economic variables also play a part”.

Which languages should be taught, aiming at what level of proficiency, for what reasons, and at what cost; these are some questions that this specific field of study analyzes with an economical approach.  In particular, most of the economics of language belongs to the micro-economic level.

One of its focus’ is on the effect of language on income, for example showing that the simple fact that belonging to a certain language group may result in a wage rate disadvantage. Some empirical studies have been conducted in order to prove the existence of significant language-based earning differentials, for example between anglophones and francophones in Canada, between migrant workers (Gastarbeiter) and native Germans in Germany, or between three language communities in Switzerland.

Another core topic in this discipline is the effect of language on markets for language-related goods and services, such as language courses, textbooks, translation services, etc. In fact, the analytical concepts of supply, demand and market for any good/service also apply to language goods.

However, the most useful application of the economics of language is its contribution to the analysis of language policy, a hot topic in a world where the knowledge of several languages is becoming increasingly important. Looking at advantages and drawbacks, the economics of language identifies and measures the elements of benefits and costs that characterize language policy options. It provides a consistent framework for the selection, design, and evaluation of language education policies, and it affects particularly university governance. As pointed out by Grin a lot of university departments in non English-speaking countries are facing a dilemma while designing study programs:

1) Should teaching and research operate in a variety of languages, even if this means resisting the trend towards doing more through the medium of language of wider circulation such as English?

2) Should teaching and research, on the contrary, strive to give such a language a greater role – as exemplified by many currently ongoing initiatives in universities around the world?

3) What reasons would we have for choosing either course of action?

Unfortunately, at the moment there is not much research addressing the above essential questions, giving economists good reason to choose this tiny but fascinating field of specialization.
