ABSTRACT
In Section 10.2, we shall list the type of statistical data that it would ideally be necessary to have in order to provide more detailed estimations of the contribution of different language skills to value creation, both in order to evaluate the amount of this contribution and to explain how it comes about. Such data are necessary, in particular, to generate more specifi c and disaggregated predictions regarding the sensitivity of productivity, costs and profi ts to changes affecting language-related variables. Again, our interest is not in explaining what happens in specifi c production lines, and even less what happens between given persons in a particular company, but to understand the processes at play in the economy as a whole or in given economic sectors with respect to multilingualism in general or with respect to specifi c languages.
