We fundamentally reorganized our manuscript so that its story and structure might be much clearer in the revision. In Section 2.2 we explicitly presented three hypotheses that are tested and discussed in later sections using information on six cluster cases. Section 5 also was reorganized so that the relationship of local cluster management to basic conditions and to national cluster polity, respectively, could be tested for each country using some cases of clusters and cluster management.
It looks as if one interview was done with the cluster manager in the six regions, but the authors also claim to have interviewed ‘the presidents of cluster firms’ (p. 8, line 20) without indicating the number.
