The Strategic Management Journal seeks to publish the highest quality research with questions, evidence and conclusions that are relevant to strategic management and engaging to strategic management scholars. We receive manuscripts with a diverse mix of topics, framings, and methods, and our acceptances reflect this diversity.
More specifically, the Strategic Management Journal seeks to publish papers that develop and/or test theory, replicate prior studies, explore interesting phenomena, and evaluate the many methodologies used in our field. SMJ also publishes studies that demonstrate a lack of statistical support in a particular sample for specific hypotheses or research propositions. We welcome a diverse range of researcher methods and are open to papers that rely on statistical inference, qualitative studies, conceptual models, computational models and various kinds of mathematical models.
The SMJ Co-editors assign submitted manuscripts to Associate Editors based on the expertise of editors and the need to balance workload among the editors.
Guidelines Regarding Empirical Research in SMJ
Reporting Results of Statistical Analyses
SMJ no longer accepts papers for publication that report or refer to cutoff levels of statistical significance (p-values). In statistical studies, authors should report either standard errors or exact p-values (without asterisks) or both, and should interpret these values appropriately in the text. Rather than referring to specific cutoff points, the discussion could report confidence intervals, explain the standard errors and/or the probability of observing the results in the particular sample, and assess the implications for the research questions or hypotheses tested.
SMJ also now requires in papers accepted for publication that authors explicitly discuss and interpret effect sizes of relevant estimated coefficients.
As of January 1, 2016, new submissions that do not conform to these policies will be returned to the authors for revision prior to review. The SMJ editorial on “Creating Repeatable Cumulative Knowledge in Strategic Management” (2016, available online at the SMJ Wiley Online website prior to publication) provides more detailed explanation of these policies.
Replication Studies and Studies that Report “Non-results”
SMJ publishes and welcomes submissions of replication studies. Additional guidelines will be provided in the SMJ special issue on replication.
SMJ publishes and welcomes submissions of studies with non-results. These types of studies demonstrate a lack of statistical support in a particular sample for specific hypotheses or research propositions. Such hypotheses or propositions should be straightforward and logical. Studies should be conducted rigorously and assess the robustness of the non-results, such as robustness to alternative measurement, statistical specifications and estimation methodologies.
SMJ strongly supports research that seeks to address interesting and important questions in strategic management that involve complicated causal processes. SMJ recognizes that statistical analyses relevant to these questions may raise the issue of endogeneity. If relevant, authors should acknowledge this issue in submitted manuscripts, and make a good faith effort to address it. In some cases, causal inference may be impossible, but statistical correlations, especially if used to rule out some alternative hypotheses or mechanisms, may still be of interest. The SMJ editorial on “Quantitative Empirical Analysis in Strategic Management” (2014, volume 35: 949-953) provides more detailed explanation.
Data Snooping and P-hacking
SMJ strongly disapproves of data snooping and p-hacking practices in empirical research. Authors of submitted papers should not search databases for statistically significant coefficients with the intention of subsequently formulating hypotheses that fit the significant coefficients. Authors also should not adapt experimental designs with the primary intention of producing statistically significant results. In addition, authors of submitted papers should address the material significance (magnitude) of the results, in addition to statistical significance.
Open Practice Initiatives
Recognizing the importance of research transparency and data sharing to cumulative research, SMJ encourages authors to share the data supporting the results in their study by archiving them in an appropriate public repository. In partnership with the non-profit Center for Open Science (COS), SMJ will award qualifying authors an Open Practice badge recognizing their contributions to the open science movement.
The Open Data badge recognizes researchers who make their data publicly available, providing sufficient description of the data to allow researchers to reproduce research findings of published research studies. Qualifying public, open-access repositories are committed to preserving data and keeping them publicly accessible via the web into perpetuity. SMJ is making the FIVES Project data repository (http://five.dartmouth.edu) available to either store the data and documentation or provide links on the FIVES website to the data and documentation on other open access websites. Other example repositories include the Open Science Framework (OSF), the various Dataverse networks, and others listed at the Registry of Research Data Repositories (http://www.re3data.org). Personal websites and most departmental websites do not qualify as repositories.
There are, of course, circumstances in which it is not possible or advisable to share data publicly. For example, there are cases in which sharing participant data could violate confidentiality, or the data were acquired under non-disclosure agreements, or the data were acquired from private vendors or other entities that prohibit sharing their data. In these cases, the authors may provide an explanation of such circumstances in the Alternative Note section of the disclosure form. The information the authors provide will be included in the article’s Open Practices note.
As of October 2017 authors will have an opportunity at the time of manuscript submission and again at the time of acceptance to inform themselves of this initiative and to determine whether they wish to participate. Applying and qualifying for the Open Data badge is not a requirement for publishing with SMJ, but this badge is further incentive for authors to participate in the open science movement and thus to increase the visibility and transparency of their research. Participating authors will be asked to complete a disclosure form after their manuscript is accepted; the badge cannot be awarded without the completed disclosure form.
More information on badges to acknowledge open practices can be found at the OSF Wiki here.

To be sure that manuscripts move through the copyediting process please observe the following guidelines:
Title Page: Please list the full names, titles, and affiliations (with complete addresses) of all authors, including e-mail, telephone, and fax information on the title page. A running head of your choice (a short title of up to 60 characters to be used at publication) should appear on the title page as well. For indexing purposes, kindly include five (5) keywords that describe your paper.
Abstract: Please supply a one-paragraph abstract of up to 125 words for all articles, research notes, and commentaries. This, as you know, is a precise summary of your entire paper, not just your conclusions, and must be able to stand alone, separate from the rest of the paper. SMJ policy is that no citations to other works are used in the abstract.
Acknowledgements: The names of any sponsors of your research, including grant numbers, and/or people you would like to thank, may be included in an acknowledgements section that should appear immediately before your list of references when your paper is accepted for publication. When submitting a paper, acknowledgements should be included ONLY on the title page and not in the text of the paper.
The suggested limit for paper size is 35 pages, which includes figures and tables and no more than 40 pages in total length. References should be single-spaced to conserve manuscript space. The language of the journal is American English. Please be sure that your paper is double-spaced and uses a 12-point readable font and 1-inch margins on all sides. Your text, including titles of sections, must be left-justified. Research notes should not be over 20 pages in length including title page and abstract, text, figures, tables and references.
• Headings and subheadings are flush with the left-hand margin and the first line of the initial paragraph appearing under each is also left-justified. Other paragraphs in a section are indented.
• In subheadings, only the first word is capitalized.
• Do not number sections.
• Do not use ampersands (&) unless it is a commonly used expression (e.g., R&D), part of a universally known product (e.g., M&Ms), or included in a company name (e.g., Standard & Poor’s).
• Commas appear before the final ‘and’ (also ‘or’) in a series.
• Double, rather than single, quotation marks are used.
• Percent is spelled out in regular text, but a % sign is used in parenthesized text and figures.
• En dashes (–) rather than hyphens (-) are used to denote a range, for example, 1996–2000; pages 124–155.
• Em dashes (—) rather than hyphens (--) are used to separate a thought or phrase from the surrounding sentence. The sentence should be able to stand alone if the material separated by em dashes were removed.
• Commas and periods always appear inside quotation marks, even if those quotation marks are used to signify the special definition of a word or phrase.
• Commas are used in numbers of 1,000 or higher.
• Indicate in the text where tables and figures are to appear, for example, ‘Insert Table 1 here.’
• Numbers one to nine are spelled out and numbers 10 and above appear as numerals. The exceptions are when numbers refer to ratings, code numbers, or begin a sentence.
• If a sentence begins with a number, the number must be spelled out. It is usually easier to rephrase the sentence.
• Footnotes, rather than endnotes, are incorporated into the text.
• The journal uses italicized rather than underlined text.
• Blocks of long quotations are indented and single-spaced.
• et al. is always italicized.
• Spell out all abbreviations at first use in the body of the article and use abbreviated forms thereafter, for example, return on investment (ROI). If an abbreviated form is used only once, it should be spelled out. This is for the benefit of readers, including students, some of whom may not be familiar with the meanings of all abbreviations.
• A zero (0) always appears in numbers less than 1 (e.g., 0.15, not .15). This holds true for tables and figures as well as within the text and footnotes.
• Example of SMJ style: In the United States; U.S.-based; in the U.S. economy.
• Appendices are placed after references. If there is only one Appendix, no number is needed after it (i.e., Appendix 1).
Figures and tables: Please do not incorporate your figures and/or tables into the text of your article other than a separate line, such as ‘Insert Table 1 here,’ where appropriate. Figures and tables should appear at the end of the manuscript after the references section. Do not embed other programs, such as PowerPoint, into the article.
• Figure numbers and titles appear centered below the figure, while Table numbers and titles appear left-justified above the table. Only the first word of a title is capitalized.
• In tables and figures, only the first word in column and row titles is capitalized.
• Within tables and figures, a zero (0) always appears in numbers less than 1 (e.g., 0.15, not .15).
• Table values are to be aligned on the decimal except where values differ widely, such values should be centered (this can, for example, apply to the N, R2, and F values in the final rows of a table).
• You may have your figures published in color; however, Wiley may charge you to do so.
Reference and citation style:SMJ uses the author-date style of citation. Citations in the text appear as name, date within parentheses, and listed alphabetically at the end of the paper. When a cited work has four or more authors, the form (main author et al., year) is to be used. Three or fewer authors should be written out at the first text citation and et al. used thereafter (italicize et al., whenever used). When reference is made to more than one work by the same author(s) published in the same year, identify each citation in the text in the following manner: (Collins, 2005a, 2005b). Online citations should end with the date of access. Please be sure that cited works that are chapters in a book or articles in a magazine include page numbers. References should contain titles and subtitles. If necessary, cite unpublished or personal work in the text, but please do not include it in the reference list.
All references must have a corresponding citation in the text and vice versa.

SMJ welcomes quality manuscript submissions from both Singapore and overseas authors. To facilitate a smooth publication process, authors who are considering submitting their manuscripts to SMJ are strongly encouraged to read the following guidelines.
To submit a manuscript, please go to www.editorialmanager.com/singaporemedj
If you do not have an SMJ author account on the Editorial Manager, create an account and log in with your username and password. Before uploading your manuscript onto the Editorial Manager, ensure you have all the documents described in the manuscript preparation section.
A one-time, non-refundable Article Processing Charge (APC) is required upon submission. Waiver of the APC applies only to Singapore Medical Association members in good standing, members of the editorial board, and authors whose articles are invited by the editor. In addition, recipients of the SMJ Reviewer Recognition Award from the previous year will enjoy waiver of the APC for the next calendar year (e.g. recipients of SMJ Reviewer Recognition Award 2016 will enjoy waiver of APC for articles submitted between January and December 2017).
Note: The APC is a non-refundable administrative fee; payment of the APC does not guarantee acceptance of the manuscript.
When the APC has been successfully processed and the submission meets the initial screening, a tracking number will be emailed to the authors, who will be able to track the status of their manuscript online.
All material submitted for publication is assumed to be submitted exclusively to the SMJ unless stated otherwise.
Editorial Review Process
All submitted manuscripts must go through rigorous Editorial checks before they are sent for peer review. The manuscripts are checked for grammar & language, plagiarism and format. Manuscripts that do not pass the initial checks will be promptly rejected without peer review.
Manuscripts that are submitted to the SMJ undergo a double-blinded peer review and are managed online. Please suggest 3-4 individuals who are especially qualified to review this work. Suggested reviewers must not be affiliated with the same institution(s) as any of the authors, or have any potential conflicts of interests in reviewing the manuscript.
Decisions on manuscripts are made in accordance with the 'Uniform Requirements for Manuscripts Submitted to Biomedical Journals' (www.icmje.org/index.html).
A request for revision does not guarantee that the paper will be accepted. Reviewers may feel that the paper meets most criteria for publication, but needs clarification on certain areas. Authors are given approximately 12 weeks to return their revised manuscript. Note that if the revision is not received after 6 months, the Editorial Office will consider the paper as ‘withdrawn’.
Two copies of a revised paper should be submitted: an anonymised, tracked copy and a clean copy. A point-by-point reply to reviewers’ and editorial comments should exclude any identification of the authors or institutions, as this letter may be sent to the reviewers for consideration during the second round of peer review.
The journal policy is generally to publish the articles chronologically according to the acceptance dates. Each accepted manuscript will be formatted in accordance with the journal style. The Editor retains the right to determine the style, and if necessary, edit and shorten any material accepted for publication.
When the galley proof is ready, the Editorial Office will send the proof to authors to check for its completeness. Confirmation or comments from the authors must be given within 48 hours of receipt of the proof, in order to avoid delays in publication of the manuscript. Authors should note that major alterations to the text will not be entertained at this stage and they are responsible for all statements made in their work, including changes made by the Editorial team and authorised by the corresponding author.
Do note that the Journal does not publish manuscripts without the author's approval of the galley proof and a completed Copyright Form. For this reason, it is vital that a working email address and fax number are provided to the Journal office. Once the author gives approval for publication, the Editorial Office will not be held responsible for any mistakes thereafter.
Note that with effect from June 2012, the editorial office has stopped sending a complimentary copy of the journal to overseas authors in view of the rising cost of international postage. Instead the corresponding authors of all manuscripts published in the SMJ will receive a high-resolution soft copy of the article upon publication.

The Vancouver style of referencing is adopted by the Journal. The detailed style of the different types of citations can be found here.
It is the authors’ responsibility to check all references very carefully for accuracy and completeness. Authors should avoid using abstracts as references. “Unpublished observations” and “personal communications” may not be used as references; if cited, a letter (from the person quoted) granting permission must be submitted. Subject to editorial approval, the person quoted will be cited in parentheses in the text and not in the reference section.
State contributions that need to be acknowledged, but do not justify authorship. Acknowledgeable contributions include (not in exhaustive order) general support by a Department Head or Chairman, technical help, and financial and/or material support (including grants). Mention conflicts of interest, if any.

SMJ is an English language journal. The use of British English is strongly encouraged. The Editorial Office does not offer major copyediting services; therefore, it is the author's responsibility to ensure that the English language is thoroughly revised before submitting the work for publication. Note that the Editorial Office reserves the right to reject a manuscript if the use of language is deemed too poor.
Authors whose native language is not English are strongly encouraged to seek assistance from a competent linguist who is familiar with medical terminology in order to ensure that the words used convey the intended meaning both accurately and clearly.

Please be advised that all manuscripts submitted to the Journal will be screened for plagiarism using CrossCheck powered by iThenticate.
The Editorial Office has encountered cases where authors have copied entire paragraphs from previously published articles. Although these passages were duly cited and credited with reference sources derived from the articles, this has been found to be unacceptable by Journal standards. Authors are required to paraphrase allreference citations in their own words. This is necessary to prevent any future misunderstandings regarding plagiarism.
In the rare case where a certain citation would lose its original meaning and essence if paraphrasing is attempted, the Journal requires authors to enclose the citation in quotation marks (“ ”) to indicate that it is a direct quote from the source. However, excessive usage of such quotation marks is discouraged and should be utilised only when absolutely necessary.
In order to stem out this unethical practice of plagiarism, the Journal adopts a zero-tolerance stance toward wholesale copying of published works. Failure to comply with these instructions will result in the outright rejection of manuscripts without peer review.

This is meant to be a platform/starting point from which the readers will delve into the work being presented in the text.
- State the purpose of the article.
- Summarise the rationale for the study or observation.
- Provide only strictly pertinent information and references.
- Review the subject extensively.
- Include data or conclusions from the work being reported.
Describe precisely your selection of the observational/experimental subjects (patients, participants or laboratory animals, including controls). Identify the following in sufficient detail, so that there is enough information to reproduce the method presented in the study:
- Apparatus. Please list the manufacturer, city, state and country of all generic drugs, equipment and software used in parenthesis. e.g. KnifeLight® instrument (Stryker Iinstruments, Kalamazoo, MI, USA).
- All drugs and chemicals used. Please list their generic names, manufacturer’s name, city and country in parenthesis, e.g. (Zoloft, Pfizer Inc, New York, NY, USA), and their exact doses and routes of administration.
- Statistical methods should also be described in this section. There should be enough detail to enable a knowledgeable reader to verify the reported results.
- Where possible, quantify findings and present them with appropriate indicators of measurement error or uncertainty (such as confidence intervals [CI]).
- Avoid relying only on statistical hypothetical testing, such as the use of p-values, which fail to communicate important quantitative information.
- Discuss the eligibility of experimental subjects.
- Provide details about randomisation.
- Describe the methods for, and success by, blinding of observations.
- Report treatment complications.
- Report losses to observation (e.g. dropouts from a clinical trial).
Please cite the standard source (this could be a manual, textbook, or the like), with page numbers stated in the References section, for the study design and statistical methods, instead of citing it directly from the article.
Specify any general-use computer programmes used (e.g. SPSS Inc, Chicago, IL, USA). Avoid the non-technical use of technical terms in statistics; words like "random", "significant", "correlations" and "sample" should not be used unintentionally. Define statistical terms, abbreviations and symbols.
- Present your results in a logical sequence in the text, Figures (if available) and Tables (if available).
- Use Graphs as an alternative to Tables, if the Tables require too many columns/rows.
- Present the results of your statistical study/analysis.
- Emphasise or summarise only the important observations.
- Repeat all the data found in the Figures and Tables in this section.
In this section, emphasise the new and important aspects of the study, and the conclusions that follow from them.
- Include the implications of the findings and their limitations, including the implications for future research.
- For new or substantially modified methods, please also adequately evaluate their limitations.
- Relate the observations to other relevant studies, and cite their reference sources. [e.g. A study in 2000 done by Lin et al also supports this conclusion.(1)]
- Link the conclusions with the goals of the study.
- State new hypotheses when warranted, but clearly label them as such.
- Include recommendations when appropriate.
- Repeat in detail, the data or other material given in the Introduction or the Results section.
- Make statements or draw conclusions that are not completely supported by your data.
- Claim priority and allude to work that has not been completed.
