Résumé : The authors of this paper use detailed linked employer-employee data from a 2003 survey in Belgium to examine how collective bargaining features affect the extent of rent-sharing. Their results show that there is substantially more rent-sharing in decentralized than in centralized industries, even when controlling for the endogeneity of profits, for heterogeneity among workers and firms and for differences in characteristics between bargaining regimes. Moreover, in centralized industries, rent-sharing is found only for workers that are covered by a firm agreement. Finally, results indicate that within decentralized industries, both firm and industry bargaining generate rent-sharing to the same extent.
