This project aims to propose new measures for the social climate in companies, to understand the complexity of the factors which shape it, and the final implications on company profitability. Corporate "social responsibility" or well-being are the subject of many debates. Nevertheless, academic research suffers from the lack of reliable and neutral data, which are most often produced and disclosed by companies themselves. Furthermore, the social climate has richer and more subtle dimensions than those usually used. For example, the question of inequalities, with the position of older employees, and opportunities for social mobility, will be examined in depth. Empirically, the project also aims to distinguish the weight of macroeconomic and cultural factors from more idiosyncratic factors (union representation and financial strategy) which are specific to the company.
