In this case-study, we use matched worker-firm Tunisian data to elicit the roles of intra-firm human capital and modern firm features in worker remunerations. We show that the estimated return to education in wage equations is not modified when replacing in the list of regressors the firm dummies, representing observed and unobserved firm heterogeneity, by the first three factors of a Principal Component Analysis of the observed firm characteristics. These factors can be interpreted as: the activity sector, the intra-firm human capital density and the modernity of the firm. These results constitute an interesting argument in favour of the presence of intra-firm human capital externalities. Moreover, the estimated education coefficient does not change when the three factors are replaced by three surrogate variables, respectively: the textile industry dummy, the intra-firm mean education, and the firm’s age.
