ABSTRACT
The concept of the ‘hollow core’ provides an effective image to describe a sectoral policy network with no strong central community. Heinz et al. perceive the ‘hollow core’ as cases where networks of policy makers lack central actors who stand in the middle of the system and have the ability to shape winning coalitions. That is, the ‘hollow core’ might be an image that is something like the opposite of the power elite (Heinz et al. 1993: xvi).
