According to this suggestion, we dropped footnote 14 with the related reference.
P. 14: On section 4.5 in the first draft, I commented that “Unlike the regional cluster initiatives in Alsace and Baden, the trinational BioValley initiative has hardly had any impact in terms of intensifying cross-border interaction, confirming problems that Koschatzky (2000) had identified long before. Indeed, many INTERREG projects fail to overcome the differences in national languages, legislations and cultures, even though the regions are neighbours.” In response, the authors now cite this paper in footnote 14 in Section 3.2. to support the view that BioValley has hardly had any impact in terms of intensifying cross-border interaction. This reformulation is incorrect as the Koschatzky (2000) paper pre-dated the BioValley initiative and does not look at INTERREG either. Unfortunately, my claim regarding the limited impact of BioValley on cross-border networking draws on conversations with practitioners and a field trip to the region, but cannot be supported by a reference as far as I know. I would therefore suggest to drop this footnote altogether.
