The project will first attempt to explain the main determining factors behind employee shareholding in France, and secondly to guide corporate decision making as to which tools to use for the income they provide to their workers. First, many political leaders stress the importance of profit sharing, whatever its form may be. A recent example in France was the 2012 Gallois report. The research community has demonstrated that profit sharing results in higher productivity. However, the levels of sharing which were measured seem quite low compared to the levels whished by leaders and researchers alike. This project will thus focus on explaining why the level is so low, and analyze several public policies aimed at stimulating profit sharing.
