This article examines the influence of equity ownership structure (stock market listing and identity of shareholders) on human resource management practices. The empirical analysis uses the 2004-2005 Workplace Industrial Relations Survey (REPONSE survey), based on a sample of 2930 establishments with 20 employees or more, representative of the French private sector. Our findings confirm the importance of listing and, to a lesser extent, of the identity of shareholders as determinants of human resource management practices, considering temporary work arrangements (agency work, fixed-term contracts and sub-contracting), pay policy (wage levels and use of variable pay) and training expenditures.
