The question of policy instruments is therefore central for the governmentality tradition of research revived in particular in the UK around Rose and Miller as much as for the governance research agenda. This raises the delicate question of conceptualizing and differentiating govervance and government. This would require a more detailed discussion that is made perilous by the fact that the conceptualization of both governmentality and governance are not stabilized. Without too much of theoretical syncretism and at the risk of confusion, it makes sense to argue that some questions are part of a parallel research agenda, e.g. policy instruments.
