Comparing Enhanced Models for Evaluating the Economic Impact of Airports

Round 1

Reviewer 1 Report

Is the demand model total or domestic flows? This should be made clear to avoid overestimations in the multipliers.

Formulas 1, 2 and 3 should look different. I propose to follow the guidelines of the journal Economic Systems Research.

For a thorough review I should have the files.

Reviewer 2 Report

1. Please supplement the necessary calculation data in the article so that readers could understand the calculation situation of the circular buffer, display time, and Huff models.

2. In Travel Time Models, minimum travel time could be a numerical value with time units, not a coefficient. Meanwhile, please explain why this formula calculates the minimum travel time from city i to airport k?

3.How do you calculate the travel time through specific reference points in Google Maps？

4. Huff's Gravitational Model has considered the distance factor. And the Circular Buffer Models also considered the distance factor. What is the difference between the two model? What is the necessity to consider the same factor repeatedly?

5.Accodring to figure 1, It might not be obvious how to calculate individual product and income.

Reviewer 3 Report

The authors proposed an interesting topic entitled Comparing Enhanced Models for Evaluating Economic Impact of Airports. We appreciate that on this topic, the impact of the pandemic and geopolitical conflicts bring significant changes to the projected economic development models.
Some major changes to the article are needed to get it to an acceptable format for publication.
Restructuring the introduction, highlighting the current framework and presenting the specific objectives of the research.
Completing the specialized literature with relevant sources and highlighting the impact of shocks on the development of the industry. Completing table 1.
Data update until 2022 (the study is carried out at the level of 2018!)
Completing the discussions in order to highlight the impact of the shocks on the economic evolution trends already presented.
Presentation of descriptive statistics. Interpretation of distributions in periods of calm and in periods of shock.
Completing the conclusions.

Reviewer 3 Report

The article was improved, but the authors did not respond to the recommendations made, as follows:
Restructuring the introduction, highlighting the current framework and presenting the specific objectives of the research. - Not achieved
Completing the specialized literature with relevant sources and highlighting the impact of shocks on the development of the industry. Completing table 1. - Not achieved (there are still 22 bibliographic references left and table 1 was not properly completed)
Data update until 2022 (the study is carried out at the level of 2018!) - We have not seen any additions to the limitations of the study regarding this non-compliance. The authors explained in the response that data availability is a quasi-generalized problem: "One of the main challenges we face is the delay in the publication of input-output matrices, which serve as essential data sources for our analysis. In the case of Brazil, the most recent official input-output matrix available is from 2015. These matrices are typically updated by the NEREUS platform with a delay of five years, meaning that the latest available data is from 2018. This delay restricts our ability to provide up- to-date information for the Brazilian economy. Moreover, this delay is not exclusive to the Brazilian context but is a common issue for global economic matrices as well. ... Given these limitations in data availability, it is currently infeasible to provide a more recent answer to your question. We acknowledge that future studies may shed light on this topic as newer input-output matrices become available. However, until updated data is released and made accessible, we are unable to provide an answer that reflects the impacts of pandemics ."
Completing the discussions in order to highlight the impact of the shocks on the economic evolution trends already presented.
Completing the conclusions - Not achieved

In the absence of appropriate answers to the recommendations made, we consider that the article cannot be published.
