For new submissions after February 5, 2024
As of February 5, 2024, we have switched to a different submission tool at Open Journal Systems (OJS).
For submissions before February 5, 2024
The review process for manuscripts submitted to the GJAE prior to February 5, 2024 will continue to be handled using Editorial Express.
Instructions for Authors
1. Manuscripts must not exceed 8000 Words including References, but not including Tables and Appendices.
2. Format: At first submission, no other rules regarding formatting have to be obeyed (“your paper your way”).
Please convert your manuscript into an anonymized PDF document prior to submission!
For final production of accepted manuscripts, authors have to format their manuscript according to a template that will be provided.
This template is available in both MS-Word and Latex format.
3. Plagiarism: The GJAE uses Cossref’s Similarity Check to detect plagiarism in the submitted manuscripts. It is up to the editors to decide whether any manuscript is rejected because of plagiarism.
4. Language: The GJAE will appear in English language only. So send us your article in English.
5. Authors should have their ORCID available when starting the submission process.
6. Authors should provide each reference with the corresponding DOI.
7. Before submitting a manuscript authors should read the following guidelines carefully:
a. The primary responsibility of an author is to present their research findings accurately and concisely and to discuss its significance objectively.
b. The author list must only contain persons who contributed significantly (in a scientific sense) to the presented work. Likewise, all persons who made such contribution must be included.
c. AI tools cannot be listed as authors of a paper. Any use of AI tools in the writing of a manuscript, image/graphic generation, or in the collection and analysis of data, must be disclosed transparently in the paper by describing how and which AI tool(s) were used.
d. Acknowledgements can be included in a dedicated section in the manuscript.
e. The manuscript needs to explain in adequate detail the data and methods used in the research, permitting other scientist to replicate the work. Authors need to adhere to the journal’s policy on data and other underlying material.
f. Authors should cite publications that have been relevant to their work and that connect readers to related research and help them to understand the presented work. Privately collected information, such as in conversation, correspondence or other interactions with third parties, should not be used or published in the author’s work without explicit permission. Sometimes a critique of a published paper may be justified; however, personal critique is not deemed acceptable in either situation.
g. “Salami” publications (i.e. redundant publication) are not permitted.
h. Authors need to take care about correct spelling and grammar.
i. Authors need to obtain the reproduction permissions for any previously published material (e.g. tables and figures).
j. Authors must disclose any competing interest.
k. Authors are not permitted to submit the same manuscript to more than one journal simultaneously.
l. The manuscript has to be original and thus has not been formally published in any other peer-reviewed publication, is not under consideration by any other journal and does not infringe any existing copyright or any other third party rights.
m. Errors obtained after publication must be communicated to the journal as soon as possible.
8. After the academic part of the paper, all accepted contributions must include the following sections before the references:
Data availability statement
Please include a statement on how the data supporting the results of your article/contribution can be accessed. If the submission is not based on data or the data it is based on is restricted (third-party data, legal or ethical constraints), this has to be explained in the data availability statement, too. Ideally, data should be deposited in a FAIR-aligned public repository. A registry to find suitable data repositories is re3data.org. Reciprocal linking of data and the article/contribution through persistent identifiers (e.g. DOIs) is best practice.
Underlying and related material
If you have other material that supports your findings (e.g. model code) or is closely related to your article/contribution (e.g. supplementary material as videos, samples, etc.) deposited on a repository, please include a brief description and the respective DOI(s) here.
Please include a statement on authors’ contributions according to the CreDIT guidelines here. CRediT (Contributor Roles Taxonomy)’s intention is to recognize individual author contributions, reduce authorship disputes, and facilitate collaboration.
Competing interests arise when issues outside research may fairly be viewed as impacting the work’s neutrality. All potential competing interests must be disclosed (“The authors declare the following competing interests: …”). If there are no potential competing interests please state “The authors declare no competing interests.”
Please insert a funding statement (if applicable) here.
If you want to acknowledge persons or institutions you can do so here.
Authors publishing in GJAE grant TIB Open Publishing (Technische Informationsbibliothek (TIB), Welfengarten 1B, 30167 Hannover, Germany) the right to publish and use the article/contribution including metadata and additional material under the conditions named below and identify itself as the original publisher.
Authors publishing in GJAE retain the copyright of their article. Where an author is prevented from being the copyright holder, minor variations may apply, e.g. in case of Crown Copyright or for US government employees. Authors requiring such variation should contact TIB Open Publishing upon submission of their contribution/article.
Authors are obliged to obtain permission for the reproduction of previously published material of other copyright holders (e.g. figures or tables). Such permission is not necessary, if the reproduction is covered by a statutory citation right, if the material is in the public domain or when the authors themselves hold the copyright for the reproduced material.
Metadata incl. abstract of the articles/contributions are distributed under the conditions of the licence CC0 1.0 Universal.
The full text is published under the licence Creative Commons attribution License 4.0
The authors acknowledge, that not all clauses of the Creative-Commons-Licenses of version 4.0 are valid in Germany. If the author plans to publish sensitive content (e. g. regarding legal or medical questions, historically sensitive issues, chemical experiments) for which liability shall be excluded as far as possible, TIB Open Publishing will provide an adapted publication agreement upon request.
The submitting author warrants
that the content of this agreement is known to and approved of by all co-authors and that the submitting author is authorized by the co-authors to enter this agreement on behalf of themselves and their co-authors that the contribution/article is original, has not been formally published in any other peer-reviewed publication, is not under consideration by any other journal;
has all necessary rights and authority to allow TIB the use of the publication, abstract and metadata pursuant to the terms and conditions set forth in this agreement and that this agreement does not infringe rights of third parties (e. g. copyright, personality or publicity rights, data protection).
the contribution/article contains nothing that is unlawful, libellous, or which would, if published, constitute a breach of contract or of confidence or of commitment given to secrecy;
reproduction permissions for any previously published material were obtained, if necessary.
the authors took due care to ensure the article´s integrity.
The submitting author shall indemnify TIB against any charges, costs or damages brought forth by other registered users or third parties against TIB claiming that the use of the publication in accordance with this agreement constitutes an infringement of third party rights and shall bear the costs of a reasonable legal defence of TIB, if the submitting author can be held responsible. The parties will cooperate closely to prevent any claims by third parties.
TIB may terminate the online provision of the publication and/or remove it from its services in the event of imminent or actual infringement of rights.
TIB may transfer all rights and obligations derived from this agreement to other public or private institutions and partners, grant licenses or consent to their use of the material without explicit consent of the authors, if other institutions support or permanently take over functions and responsibilities from TIB.
In certain cases, corrections may be necessary to preserve the integrity of scientific literature. The following means to correct the scientific record can be applied:
A corrigendum should be issued if a minor part of an otherwise reliable publication is found to be inaccurate. This might be especially the case for honest errors. Also if the author list is incorrect, a corrigendum can be issued.
GJAE will follow the retraction guidelines of COPE. Retractions are accompanied with a respective note explaining the reasons.
Manuscripts can be withdrawn before publication. However, published articles will not be “unpublished”. Only in case of legal action, full texts might be removed with a corresponding statement on the article´s landing page.
Expression of concern
If they have well-founded concerns and feel that readers should be made aware of potentially misleading information contained in an article, journal editors may consider issuing an Expression of Concern. Expressions of concern can, however, be provided only if an inquiry into the problems relating to the article has proven to be inconclusive and if clear indications exist that the issues are legitimate. Editors should be mindful in all situations that an Expression of Concern brings the same risks to the reputation of a researcher as a retraction, and that in most cases it is preferable to publish a retraction until an independent investigation has reached a definitive conclusion.
Publication Ethics and Publication Malpractice Statement of the German Journal of Agricultural Economics (GJAE)
These guidelines are based on Elsevier recommendations and COPE’s Best Practice Guidelines for Journal Editors.
The publication of an article in the peer-reviewed German Journal of Agricultural Economics (GJAE) is a process of permanent knowledge improvement.
It is a direct reflection of the quality of the work of the authors and the institutions that support them. Peer-reviewed articles support and embody the scientific method. It is therefore important to agree upon standards of ethical behavior for all parties involved in the act of publishing: authors, journal editors, peer reviewers and the GEWISOLA.
The GeWiSoLa as the scientific association owning the GJAE takes its duties of guardianship over all stages of publishing extremely serious and we recognize our ethical and other responsibilities.
We are committed to ensuring that advertising, reprint or other commercial revenue have no impact or influence on editorial decisions. In addition, the Editorial Board will assist in communications with other journals and/or publishers where this is useful to the editors.
Authors of reports of original research must present an accurate account of the work performed as well as an objective discussion of its significance. Underlying data must be represented accurately in the paper. A paper should contain sufficient detail and references to permit others to replicate the work. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. For papers involving human subjects’ research, the authors must communicate to the editors before the manuscript can be reviewed, if the research involves deception of human subjects. This communication includes the documentation of the extent and nature of deception involved and the research justification for deception. The editor may return manuscripts in which deception is deemed unwarranted or excessive given the research justification.
Review and professional publication articles must also be accurate and objective, and editorial ‘opinion’ works should be clearly identified as such.
Data access and retention
Authors may be asked to provide the raw data in connection with a paper for editorial review, and must retain such data for five years after publication.
Originality and plagiarism
The authors must ensure that they have written entirely original works, and if the authors have used the work and/or words of others that these have been appropriately cited or quoted. Plagiarism takes many forms, from passing off another’s paper as the author’s own paper, to copying or paraphrasing substantial parts of another’s paper (without attribution), to claiming results from research conducted by others. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable.
Multiple, redundant or concurrent publication
An author should not in general publish manuscripts describing essentially the same research in more than one journal. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. In general, an author should not submit a previously published paper for consideration in another journal.
Acknowledgement of sources
Proper acknowledgment of the work of others must always be given. Authors should cite publications that have been influential in determining the nature of the reported work. Information obtained privately, for example in conversation, correspondence, or discussion with third parties, must not be used or reported without explicit, permission from the source. Information obtained in the course of confidential services, such as refereeing manuscripts or grant applications, must not be used without the explicit written permission of the author of the work involved in these services.
Authorship of the paper
Authorship should be limited to those who have made a significant contribution to the conception, design, execution or interpretation of the reported study. All those who have made significant contributions should be listed as co-authors. Where there are others who have participated in certain substantive aspects of the research project, they should be acknowledged or listed as contributors. The corresponding author should ensure that all co-authors have seen and approved the final version of the paper and have agreed to its submission for publication.
Hazards and human or animal subjects
If the work involves chemicals, procedures or equipment that have any unusual hazards inherent in their use, the author must clearly identify these in the manuscript. If the work involves the use of animal or human subjects, the author should ensure that the manuscript contains a statement that all procedures were performed in compliance with relevant laws and institutional guidelines. Authors
should include a statement in the manuscript that informed consent was obtained from human subjects. The privacy rights of human subjects must always be observed.
Disclosure and conflicts of interest
All authors should disclose in their manuscript any financial or other substantive conflict of interest that might be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be disclosed. Examples of potential conflicts of interest which should be disclosed include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Potential conflicts of interest should be disclosed at the earliest stage possible.
Fundamental errors in published works
When an author discovers a significant error or inaccuracy in his/her own published work, it is the author’s obligation to promptly notify the journal editor and cooperate with the editor to retract or correct the paper. If the editor learns from a third party that a published work contains a significant error, it is the obligation of the author to promptly retract or correct the paper or provide evidence to the editor of the correctness of the original paper.
The editor of a peer-reviewed journal is responsible for deciding which of the articles submitted to the journal should be published. The validation of the work in question and its importance to researchers and readers must drive such decisions. The editor is guided by the policies of the journal’s editorial board and constrained by such legal requirements as shall then be in force regarding libel, copyright infringement and plagiarism. The editor may confer with other editors or reviewers in making this decision.
An editor should evaluate manuscripts for their intellectual content without regard to the author’s race, gender, sexual orientation, religious belief, ethnic origin, citizenship or political philosophy.
The editor and any editorial staff must not disclose any information about a submitted manuscript to anyone other than the corresponding author, reviewers, potential reviewers, other editorial advisers, as appropriate.
Disclosure and conflicts of interest
Unpublished materials disclosed in a submitted manuscript must not be used in an editor’s own research without the express written consent of the author. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Editors should recuse themselves, i.e. should ask a co-editor, associate editor or other member of the editorial board to review manuscripts, in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or (possibly) institutions connected to the papers. Editors should require all contributors to disclose relevant competing interests and publish corrections if competing interests are revealed after publication. If needed, other appropriate action should be taken, such as the publication of a retraction or expression of concern. Non-peer reviewed sections of the journal should be clearly identified.
Involvement and cooperation in investigations
An editor should take reasonably responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper. Such measures will generally include contacting the author of the manuscript or paper and giving due consideration of the respective complaint or claims made, but may also include further communications to the relevant institutions and research bodies, and if the complaint is upheld, the publication of a correction, retraction, expression of concern, or other note, as may be relevant.
Every reported act of unethical publishing behavior must be investigated, even if it is discovered after publication.
Contribution to editorial decisions
Peer-review assists the editor in making editorial decisions and through the editorial communications with the author may also assist the author in improving the paper. Peer-review is an essential component of formal scholarly communication, and lies at the heart of the scientific method.
All scholars who wish to contribute to publications have an obligation to do a fair share of reviewing.
Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse him/herself from the review process.
Any manuscripts received for review must be treated confidentially. They must not be shown to or discussed with others except as authorized by the editor.
Standards of objectivity
Reviews should be conducted objectively. Personal criticism of the author is inappropriate. Referees should express their views clearly with supporting arguments.
Acknowledgement of sources
Reviewers should identify relevant published work that has not been cited by the authors. Any statement that an observation, derivation, or argument had been previously reported should be accompanied by the relevant citation. A reviewer should also call to the editor’s attention any substantial similarity or overlap between the manuscript under consideration and any other published paper of which they have personal knowledge.
Disclosure and conflict of interest
Unpublished materials disclosed in a submitted manuscript must not be used in a reviewer’s own research without the express written consent of the author. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies or institutions connected to the papers.
