Response to reviewersDear editor, dear reviewer, Thank you to take the interest in reviewing this paper for the second time. Again, we appreciate the comments and suggestions, and adjusted the paper accordingly, so that it becomes more clear and better underpinned. Our response to the comments and the changes in the paper are indicated below. We focused in our responses first on the general comments. A short reaction to the more detailed comments follows afterwards.The authors made great strides in revising the manuscript. There are three primary concerns and several specific questions that need to be addressed before this piece could be considered publication worthy.
First comment:The first concern is the need for specific citations to back up the assertions made by the authors. Citations should be added to Table 3 or noted that this is the authors' creation if this is the case. Several blanket statements are also made throughout the piece without referencing the relevant literature. For example, on pg. 10 the authors state: "They however did not assign the right benefits to the right actors, but only calculated an overall economic benefit." What are the right benefits? Who are the right actors? How is this grounded in the literature? Some instances where clarification is needed are listed in the specific comments below, but it is recommended the authors go through the text and add citations to the piece where necessary, above and beyond those instances mentioned below. Ghent and Eindhoven (FOD Financiën, 2013;Belastingsdienst, 2013)
Second comment (a):A second area of concern is the discussion and conclusion. The authors present case study evidence about the value of their bottom-up approach for computing indirect benefits. Are these indirect benefits likely to be the same in other places? Ghent and Eindhoven are relatively small cities with a specific economic and cultural context. Isn't it likely that the magnitude of indirect benefits will vary by region, as demonstrated in recent broadband work by Mack et al., 2011 andMack and Rey, 2013, as well as classics such as Forman et al., 2005a? Another item that merits more thorough treatment is the industry specific nature of this impact. Looking at e-business across all companies does not deal explicitly with the potential for industry specific variation in indirect benefits related to the importance of agglomerative forces and industry specific business processes. Prior work by Forman et al. (2003Forman et al. ( , 2005b finds industry specific variation in dial-up adoption by firms, and this is likely the case for broadband and the indirect impacts associated with e-business. The authors mentioned this in the introduction of the original manuscript and should include it in a more thorough discussion of future work.
Second comment (b):Finally, what is the impact of the assumptions of the values chosen for the innovation and imitation coefficients of the Bass Curve? Does increasing or decreasing these values change the results or are they relatively robust? A...
