Based on results from the different fields of the game theoretic literature on strategic interactions and social dilemmas, gift exchange and procedural utility, we argue that corporate social responsibility and relational skills i) with other firms; ii) between employers and workers iii) among workers and iv) with stakeholders are associated to positive effects on productivity. We test our research hypothesis in a comparative perspective on small, medium and large sized Italian firms. We find that size matters when investigating the impact of relational skills on added value per worker after controlling for relevant concurring factors. The identified significant skill related components are: i) corporate policies considering strategic workers’ wellbeing; ii) team working attitudes considered as priority soft skills when hiring workers; iii) initiatives in favour of the productive network operating in the same local area; iv) involvement of stakeholders in CSR projects. Our findings show that the fourth component (stakeholder involvement) is positive and significant for all (small, medium and large) size classes, while the first (workers wellbeing) for small and medium firms, the second (team working) applies mainly to medium firms, and the third (initiative for the local productive network) to medium and large firms. Instrumental variable estimates on the relational skill principal component suggest that a causality link exists beyond these significant correlations. Our conclusion is that scale has an inverse U-shaped effect on the impact of team skills, weakens the impact of gift exchange mechanisms, while it reinforces those of investment in the local productive environment on added value per worker
