Article dans une revue: Recent years have witnessed an enormous amount of reorganization of the corporate sector in the United States and Europe.

Workers' empowerment and the move to a flatter organizational structure emerge as an equilibrium when competition is not too tough and not too weak. The model predicts merger waves or waves of outsourcing when countries become more integrated in the global economy as the corporate sector reorganizes in response to an increase in international competition.
