In order to assess the validity of this assumption, this article identifies the trajectory of specialization and coordination in four countries (New Zealand, United Kingdom, Sweden, France). The results support the assumption, although different trajectories are discernible. Also, the results point to the renewed emphasis on coordination based on hierarchy, along with markets and networks. - Reproduced.  aPublic administration  aAdministrative reform  aPeters, B.
