ETHICAL PRINCIPLES

• Journal of Finance Letters (Maliye ve Finans Yazıları) adheres to academic principles and ethical values in its publishing policy. It continues its publishing activities in compliance with national and international standards related to ethical principles and values. In this context, the standards set by the Committee on Publication Ethics (COPE) and the principles outlined in the Higher Education Institutions Directive on Scientific Research and Publication Ethics are taken into consideration.

• If a submitted manuscript is found to violate the accepted research and publication ethics during the review process, its publication request will be rejected. If such a violation is detected after publication, the manuscript will be retracted.

• Our journal engages in ethical, targeted, and non-intrusive communication with potential authors. We do not engage in excessive solicitation or misleading promotional practices. All marketing efforts are aligned with the journal’s academic mission and scope.

For Authors

• Authors must review, confirm, and commit to compliance with the ethical standards, publishing principles, and writing guidelines adopted by the journal before submitting their manuscripts. Our journal endorses the guidelines in Wager & Kleinert (2011)* for authors. The guidelines are summarized below. Please click here for details.
• *Wager E & Kleinert S (2011) Responsible research publication: international standards for authors. A position statement developed at the 2nd World Conference on Research Integrity, Singapore, July 22-24, 2010. Chapter 50 in: Mayer T & Steneck N (eds) Promoting Research Integrity in a Global Environment. Imperial College Press / World Scientific Publishing, Singapore (pp 309-16). (ISBN 978-981-4340-97-7)
  
  
• Soundness and Reliability
  
• Research integrity begins with rigorous methodology and ethical execution. The standards emphasize that all research must comply with legal and ethical norms, including adherence to institutional review board (IRB) approvals, animal welfare regulations, and data protection laws. Researchers must ensure their work is methodologically sound, replicable, and free from avoidable errors. This involves using appropriate analytical techniques, consulting specialists when needed, and meticulously verifying data, calculations, and interpretations at every stage of publication.
  
• A critical aspect of reliability is collective accountability. All authors must review the final manuscript to confirm accuracy and completeness. This shared responsibility discourages negligence and ensures that published findings reflect a unified commitment to truthfulness. Institutions are urged to foster environments where meticulousness and transparency are prioritized, as errors in published work can undermine public trust and scientific progress.
  
  
• Honesty in Reporting
  
• Honesty is the cornerstone of credible research. Authors must avoid fabrication (inventing data), falsification (distorting results), and inappropriate manipulation (e.g., misleading image edits in microscopy or gels). Transparent methodology is essential: publications should provide sufficient detail for independent replication, including raw data availability where feasible.
• The guidelines explicitly reject selective reporting. Negative or contradictory results must not be omitted, as they contribute to a balanced understanding of a topic. Sponsors or funders must not suppress unfavorable findings, except in rare cases involving national security. Authors are also obligated to promptly correct errors post-publication through retractions or corrigenda, reinforcing the self-correcting nature of science.
• Citations and references must reflect genuine engagement with prior work. “Citation stuffing” (irrelevant references) or copying references without reading the original work is unethical. Proper attribution safeguards intellectual property and contextualizes the study within the broader scholarly discourse.
  
  
• Balance and Contextualization
  
• Research publications must avoid bias by fairly representing existing literature. Scholarly reviews should synthesize findings regardless of whether they support the authors’ hypotheses, and opinion pieces must be clearly labeled as such. Acknowledging limitations—such as sample size constraints or methodological weaknesses—enhances credibility and guides future research.
  
  
• Originality and Plagiarism Avoidance
  
• Submissions must be original, unpublished works. Plagiarism, including “self-plagiarism” (recycling text without citation), is strictly prohibited. Authors must obtain permissions for reproduced copyrighted material (e.g., figures, tables) and disclose prior publications or overlapping analyses derived from the same dataset.
• “Salami slicing” (splitting a single study into multiple papers) is discouraged unless justified by distinct hypotheses or audiences. Translations or adaptations must credit the original work and comply with copyright laws.
  
  
• Transparency in Funding and Conflicts of Interest
  
• Full disclosure of funding sources—direct, indirect, or in-kind—is mandatory. Authors must clarify the sponsor’s role in study design, analysis, or reporting. Financial conflicts (e.g., stock ownership, consultancy fees) and non-financial biases (e.g., personal relationships, institutional affiliations) that could influence interpretation must be declared. Journals may require conflict-of-interest statements to ensure readers can assess potential biases.
  
  
• Authorship and Contribution Ethics
  
• Authorship must reflect substantive intellectual contributions, such as study design, data analysis, or critical manuscript revisions. Honorary (“gift”) authorship, ghostwriting (excluding contributors who meet criteria), and coercive inclusion (“guest” authorship) violate ethical norms. Institutions and journals should establish clear authorship criteria upfront and mediate disputes transparently.
• All authors must approve the final manuscript and any subsequent changes to the author list. The corresponding author acts as a liaison with editors but must involve co-authors in major decisions, such as responding to peer review. Misleading acknowledgments—implying endorsement by uninvolved individuals—are prohibited.
  
  
• Accountability and Post-Publication Conduct
  
• Authors must understand and endorse the entire publication. While collective responsibility is standard, individual roles (e.g., data analysis vs. writing) may be specified. Post-publication, authors should engage constructively with critiques, provide clarifications, and share data/materials upon request (within ethical and legal boundaries).
• Data hoarding for personal gain or authorship coercion contradicts collaborative ideals. Institutions and funders should establish clear data-sharing policies, balancing openness with privacy concerns.
  
  
• Adherence to Peer Review Conventions
  
• Authors must respect the peer review process by avoiding simultaneous submissions to multiple journals unless co-publication is agreed upon. Withdrawing a manuscript after peer review, or failing to address reviewer comments post-conditional acceptance, wastes editorial resources and delays knowledge dissemination.
• Press embargoes should be honored to align media coverage with publication timelines. Press releases must accurately represent findings without sensationalism, as misrepresentation can mislead policymakers and the public.
  
  
• Ethical Reporting Involving Humans or Animals
  Research involving humans or animals requires documented ethical approvals (e.g., IRB, animal care committee) and informed consent. Identifiable data should only be published with explicit participant permission, considering risks of unintended recognition in digital archives.
  
• Clinical trials must be prospectively registered, and results—positive or negative—must be published to prevent publication bias. Journals may request study protocols to verify adherence to pre-specified methods. Statistical analyses should follow pre-defined plans, with post hoc analyses clearly labeled as exploratory.
  
  
• Conclusion: Collective Responsibility for Integrity
  
• The guidelines underscore that research integrity is a shared duty. Institutions must train researchers in ethical standards, funders must avoid undue influence, and journals must enforce transparent policies. By adhering to these principles, the scholarly community can maintain public trust, foster collaboration, and advance knowledge responsibly.
  
  
• Click here for details on ethical committee approval information.
• For researches requiring ethical committee approval, information about the approval (committee name, date, and reference number) should be included in the methodology section and on one of the first or last pages of the article. In "case reports", the article should include a statement confirming that an informed voluntary consent form was signed.

SCIENTIFIC RESEARCH AND PUBLICATION ETHICS

Our journal adheres to national and international standards to prevent, detect, and manage violations of scientific research and publication ethics. In this context, the principles of the Committee on Publication Ethics (COPE) and the Higher Education Institutions Directive on Scientific

Research and Publication Ethics serve as the foundation. Below, the definitions of ethical violations, their detection and handling processes, and complaint management are explained in detail.

Scientific Research and Publication Ethics Violations

Scientific research and publication ethics violations are serious breaches that undermine academic integrity and erode trust in scientific work. Our journal recognizes the following types of violations and maintains a zero-tolerance policy against them:

• Plagiarism: Presenting others' original ideas, methods, data, or works as one’s own without proper citation according to academic standards.
  
• Fabrication: Using non-existent or falsified data in scientific research.
  
• Falsification: Altering research data or records, falsely presenting unused devices or materials as used, or distorting results due to conflicts of interest.
  
• Duplicate Publication: Presenting a previously published work as a new publication for academic promotion or appointments.
  
• Salami Slicing: Fragmenting research findings into multiple publications in a way that compromises the integrity of the study.
  
• Unjust Authorship: Including individuals who made no significant contributions as authors, excluding contributors, altering author order without justification, or demanding authorship through influence.
  
• Failure to Acknowledge Support and Contributions: Not properly crediting individuals, institutions, or organizations that provided support during the research process.
  
• Unauthorized Use of Sources: Citing unpublished theses or studies as sources without the author's permission.
  
• Violation of Ethical Rules: Breaching ethical guidelines in research involving humans or animals, or disregarding patient rights.
  
• Breach of Confidentiality: Sharing information from a submitted manuscript under review with third parties without the author’s consent.
  
• Misuse of Resources: Using research funds, facilities, or equipment for unauthorized purposes.
  
• False Allegations of Ethical Violations: Making unfounded and deliberate accusations of ethical misconduct.
  
• Violation of Participant Rights: Collecting and publishing survey or attitude research data without obtaining informed consent from participants or necessary institutional permissions.
  
• Violation of Environmental and Animal Rights: Engaging in research practices that harm animal health or ecological balance.
  
• Conducting Research Without Permission: Performing research or experiments without obtaining the necessary institutional and legal approvals.

• Failure to Fulfill the Duty of Disclosure: Not informing relevant parties about potential harmful consequences of research.
  
• Violation of Data and Information Security: Using data obtained from other individuals or institutions beyond the permitted scope or failing to comply with confidentiality rules.
  

Process for Identifying and Addressing Scientific Research and Publication Ethics Violations

Our journal adopts a proactive approach to uphold the integrity of academic publishing and implements the following processes to prevent, detect, and manage ethical violations:

• Preventive Measures: Editors and publishers take active measures to prevent misconduct such as plagiarism, data fabrication, and citation manipulation.
  
• Editorial Screening: Submitted manuscripts are checked using plagiarism detection software. Manuscripts with a similarity rate exceeding 20% are rejected.
  
• Independent Investigation: If misconduct is suspected, the editorial board initiates a neutral and confidential investigation.
  
• Expert Review: If necessary, independent experts or ethics committees are consulted for assessment.
  
• Interim Measures: The review or publication process of a manuscript may be suspended during an investigation.
  
• Correction or Retraction: If misconduct is confirmed, the manuscript is corrected, retracted, or an editorial note is published. Retractions are publicly announced on open-access platforms.
