The Propagation of the Economic Impact through Supply Chains: The Case of a Mega-City Lockdown against the Spread of COVID-19


Dear Dr. Inoue,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Authors have provided a theoretically rigorous framework to analyze the influence that COVID-10 brought to the world. Two peer reviewers suggest that further modification and supplement are necessary before fully acception by PLOS ONE, and I hold the same view.

Please submit your revised manuscript by Sep 10 2020 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at When you're ready to submit your revision, log on to and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in to enhance the reproducibility of your results. assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see:

We look forward to receiving your revised manuscript.

Kind regards,

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

Reviewer #1: Partly

Reviewer #2: Yes


2. Has the statistical analysis been performed appropriately and rigorously?

Reviewer #1: N/A

Reviewer #2: Yes


3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes


4. Is the manuscript presented in an intelligible fashion and written in standard English?

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The Paper is written in well mannered. In introduction section, author (s) are requested to explain the pinpoint background and the objective of the research. This leads to a greater interest by the reader.

Literature review section is not enough to describe the research problem. Author (s) are requested to provide strong literature for present research.

The conclusions should show the novel results with the past situation research for this authors are advices to include the general findings of the research. It is advisable to provide the limitation of this research in a very concise manner.

The overall work done by the author is good.

Reviewer #2: This paper aims to quantify the economic effect of a possible lockdown of Tokyo to prevent the spread of COVID-19 by applying an agent-based model with the actual supply chains of nearly 1.6 million firms in Japan, which is a hot topic and provides a relatively quality paper. Especially in 2020, COVID-19 produces dramatically negative effect on global supply chain and many scholars pay more attention to that. There are some minor comments for the authors.

1. As we know, supply chains whether in a country or in the world is a network. Using network quantitative method to explore supply chains is also a major way. This paper employs the dynamic agent-based model of Inoue and Todo that is an extension of the model of Hallegatte, I would like to see the authors spend more time to introduce the differences between the method mentioned in the paper and network quantitative method.

2. COVID-19 likes a kind of shock or emergency and many scholars have studied policy shock and public emergency bring about impact on economic or social development, so the author need to show relative literatures published to deeply illustrate the paper’s highlights.

3. This study attempts to quantify the economic effect of COVID-19 by taking into account the propagation effect across regions through inter-firm supply chains, why does this paper choose firm-level data? I don’t quite clear to see the main contributions at the end of the introduction.

4. Please explain further what does Lockdown means and what the actual prerequisites of Lockdown are?

5. I would like to see the process of how to match firm-level data with IO industry-level data?


6. PLOS authors have the option to publish the peer review history of their article (what does this mean?). If published, this will include your full peer review and any attached files.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
