Guidelines for Submitting Manuscripts
All submissions to the Journal of Agricultural and Resource Economics must be submitted electronically to the editorial team at http://www.jareonline.org. To ensure author anonymity, JARE accepts submissions only in PDF format. Author and institutional identifications will be removed from PDF file submissions by the editorial team prior to being sent to reviewers. Receipt of manuscripts will be acknowledged by e-mail.

A) Author Certifications
Authors submitting manuscripts to JARE certify that the material in the manuscript (or modification thereof) has not been published, is not being published, and is not currently being considered for publication elsewhere. Authors also certify that the material in the manuscript, to
the best of their knowledge, does not infringe upon other published material protected by copyright. Authors also acknowledge they have read and agree to the policy on data access and estimation procedures outlined below.

B) Data Access and Estimation Procedures
Authors are expected to document their data sources, data transformations, models, and estimation procedures as thoroughly as possible. Authors are also expected to make data available at cost for replication purposes for up to 5 years from publication.

C) Title Page
In a separate PDF file, provide the title of the manuscript and author(s)’ name(s) centered and in boldface type. At the bottom of the same page, provide professional title(s), institutional affiliation(s), acknowledgments of colleague reviews and assistance, and institutional support as an unnumbered footnote. Please be sure to fully acknowledge any USDA funding source, including grant or project number(s).

D) Abstract Page
Include an abstract of 100 words or less, followed by up to eight key words (or short phrases) listed in alphabetical order. To ensure anonymity in the review process, authors should not identify themselves on the abstract page or in any headers.

E) Text
Submitted manuscripts should be no longer than 35 pages (not including reference list, tables, and figures). Double-space all text, including the abstract, acknowledgments, footnotes, and references. Place each table and figure on a separate page following the references. Make sure
that the manuscript follows the style and formatting requirements outlined below.

F) Publication Costs
Authors submitting manuscripts agree to assume obligation for payment of page charges at publication. Current page charges are $79/printed page for WAEA members and $89/printed page for nonmembers.

G) Guidelines for Accepted Manuscripts
Upon acceptance, authors must send a .doc(x) or .tex copy of the accepted manuscript to amy@precisionedits.com. Make sure that the manuscript follows the style and formatting requirements outlined below.

Title Page
The following items must be included on the title page, which must be separate from the manuscript.

A) Title
A precise, concise description of results gathered and/or analysis performed, no more than 15 words long.

  • Avoid useless words and phrases (e.g., “influence of,” “effect on,” “evaluation of,” “results of,” “impact of,” etc.).
  • Spell out abbreviations.
  • Capitalize the first and last words of the title. Capitalize all other words except for articles (e.g., “a,” “the”), conjunctions (e.g., “and,” “but,” “or”), and prepositions (e.g., “in,”     “on,” “after,” “of”) unless they are used adjectivally or adverbially (e.g., “Look Up,” “Turn Down”) or used in pairs (e.g., “With or  Without,” “Above and Below”).
  • Capitalize the second half of hyphenated words (e.g., “Spatial-Dynamic Benefits,” not “Spatial-dynamic Benefits”) unless the first half is a prefix (e.g., “Re-estimate,” not “Re-Estimate”).
  • Always lowercase the second part of a species name (e.g., Cephus cinctus).

B) Running Title
An abbreviated version of the title, no more than 40 characters, which will appear on the front cover and in the header of odd-numbered pages.

C) Author Names
The full name(s) of the author(s), on one line, separated by commas. Do not include degree abbreviations, professional titles, or contact information.

D) Author Affiliations
Authors’ full name followed by position title, departmental affiliation, and university or other organization. Do not include mailing address, telephone number, or email address.

  • Authors should be presented in the same order as listed above.
  • Do not capitalize position title.
  • Capitalize department and university name (or company name if relevant).
  • Indicate corresponding author parenthetically after the author’s name.

For example:
   “Marion W. Gushee (corresponding author) is an assistant professor of agricultural business and economics in the Department of Agricultural Science at Western Texas A&M University.”

If there are multiple authors from same institution, group them together (i.e., do not repeat the institution information); this may override the original order of authors: “Benjamin M. Johnson is a graduate student, Leslie James Tompkins (corresponding author) is an associate professor, Vasyl Szpak is an assistant professor, and Nikolai Shmelov is a graduate student in the Department of Agricultural Economics and Agribusiness and Russell C. Gourley is a professor in the Department of Chemical Engineering at the University of Arkansas.”

In some cases, it may be preferable to indicate authors’ affiliation at the time the work was produced:
    “B. Mae Tayntor is a former graduate student in the Department of Agricultural and Applied Economics, University of Georgia.”

E) Acknowledgments
Credit, acknowledgment, or thanks for material or informational assistance. Acknowledge any USDA or other funding source, including grant or project number(s). Use first person and full names (e.g., “We thank Karl Johnson for his many insights.”). Do not include titles (e.g., Dr., Prof., secretary), formal address (e.g., Mr., Mrs., Miss, Ms.), or degree abbreviations (e.g., PhD, MD).

Abstract Page
A) Title
Repeat the title of the manuscript at the top of the abstract page.

B) Abstract
A concise, self-explanatory, summary of the article, no more than 100 words. Do not duplicate the title in the abstract. Do not include citations, footnotes, or references to tables and figures in the abstract. Do not include references unless absolutely necessary. Begin page numbers on the
abstract page (page 1).

C) Additional Keywords
A list of up to eight keywords or phrases not already used in the title. List these alphabetically, separated by commas. Only capitalize proper nouns. Choose keywords to indicate the content and/or method of the manuscript. Avoid general or broad words and phrases such as “yield” or
“growth.” Keywords should not repeat words or phrases that appear in the title.

Article Text
Begin the manuscript at the top of a new page. Suggested manuscript length is no more than 25 text pages (not including references, tables, and figures). The text should be single-column format, 12-point Times New Roman font, double-spaced, with continuous line numbering— including the abstract, acknowledgments, footnotes, and references. Allow 1” margins on all sides. Do not justify right margins or use end-of-line hyphenation features.

A) Headings
Provide concise, descriptive headings for each section and subsection. The Journal of Agricultural and Resource Economics does not prescribe specific headings (e.g., “Materials and Methods,” “Results and Discussion”). The introduction should include a heading (“Introduction” is acceptable).

Headings (12-point font) should be capitalized using the main title guidelines.
• Level 1: Centered, bold
• Level 2: Left-justified, italicized
• Level 3: Left-justified, plain typeface

B) Footnotes
Use superscript Arabic numbers within the text, numbered consecutively throughout the manuscript. Place footnotes at the bottom of the page on which the footnote is referenced. If using Microsoft Word, use the automatic footnote feature.

C) Math/Equations
Display all but very short mathematical expressions centered and on a separate line. Label all displayed equations on the left margin with consecutive Arabic numerals in parentheses.

Write all equations using LaTeX, MathType, Equation Editor, or equivalent. Under no circumstances should equations be submitted as images. These will need to be rewritten by the authors.

JARE follows the National Institute of Standards and Technology guidelines for typefaces for symbols in scientific manuscripts (see https://physics.nist.gov/cuu/pdf/typefaces.pdf). Use italic typeface for variables and italic boldface for vectors and matrices—both within equations and within the text. Equations referenced in the text must be labeled and the equation number enclosed in parentheses (e.g., “equation (5),” “assumption (2)”). Do not capitalize “equation.”

When variables (or other entities) are “equal to 1,” if applicable, add “and 0 otherwise.” Do not write out “one” and “zero” in these instances.

D) Citations
Parenthetical citations should use the author(s) name, followed by a comma and the year of publication (Johnson, 1992). Separate multiple parenthetical citations using semicolons (e.g., Johnson, 1992; Bekkerman, 2003). Use “et al.” (no italics, note punctuation) for sources with
four or more authors (Smith et al., 2007). For sources with fewer than four authors, write out all of the authors’ names in the text.

When listing two or more citations parenthetically in the text, list chronologically first, then alphabetically if necessary (e.g., “Jones and Perkins, 1996; Kader, 2001; Smith, 2001”).

When one author or set of authors has more than one publication in a year, use “a,” “b,” “c,” etc. to distinguish (e.g., “USDA, 2017a,” “USDA, 2017b”, “USDA, 2017a,b,” “Johnson, 1996b”).

Quotations must appear exactly as written in the original published work (misspellings in the original work must be included as written and followed by “[sic]”).

Appendices and Online Supplements
Appendices and online supplements may be submitted with the manuscript. Appendices should include information that may be needed to understand the assumptions and/or conclusions discussed in the manuscript but that are too long to include in the main text. Examples include
short mathematical proofs, variable description tables, and additional results tables, among others. Reference each appendix at least once in the text. Appendix footnotes continue numbering from main text. Tables, figures, and equations should be labeled A1, A2, etc. Multiple appendices are A, B, etc.

Supplementary materials are those that may interest and be of import to readers but are not necessary to understand the assumptions and/or conclusions of the manuscript. Examples include lengthy mathematical derivations, tables with robustness results, and survey instruments, among others. Supply supplementary online information as a separate file. Refer to tables and figures in the text as Table S1, figure S2, etc., or more generally as “the online supplement (www.jareonline.org).” Online supplements will not be copy edited. Color figures are acceptable
in supplemental material.

References
Begin the reference section on a separate page. All citations in the text must be included in the references, and all references must be mentioned in the text. Check the reference list against literature citations in the text before submitting the manuscript for publication. Ensure that working papers and in-press articles have not been published before submitting your work. Papers submitted using LaTeX must include a bib file or equivalent and use the \cite feature.

  • Do not abbreviate departments, journal titles (e.g., “Journal of Agricultural and Resource Economics,” not “J. Agr. Res. Econ.”), or agencies (e.g., “U.S. Department of Agriculture,” not “USDA”).
  • Italicize the titles of journals, books, and reports (e.g., “Journal of Agricultural and Resource Economics”).
  • Where relevant, give full pagination (e.g., “1101–1102,” not “1101–2” or “1101–02”).
  • Use both volume and issue number, regardless of whether a journal paginates consecutively throughout the year.
  • For U.S. cities, include 2-digit state abbreviation (e.g., “New York, NY,” “Boston, MA”). For international cities, include full name of city and country (e.g., “Amsterdam, Netherlands,” “Toronto, Canada”).
  • Unpublished data or information received personally should be noted parenthetically rather than cited [e.g., “(R.L. Johnson, unpublished data)” or “(A. Bekkerman, personal communication)”].
  • If a paper or manuscripts has been accepted for publication, cite the work as “(forthcoming).”
  • Where no date is available (generally for websites or unpublished material), use “n.d.”

A) Author Names
List references alphabetically by authors’ name, then chronologically (if an author or group of
authors has more than one listed source).

  • Do not use ampersands (&) in a list of authors. Instead, use the word “and.”
  • Do not use “et al.” in the reference section. Write out all of the listed authors.
  • Do not use a long dash to indicate an identical author.
  • One author:
    Bekkerman, A.L.
  • Two authors:
    Bekkerman, A.L., and R.S. Johnson
  • Three or more authors:
    Bekkerman, A.L., R.S. Johnson, and M.W. Gourley
  • Do not abbreviate corporate or organizational authors or publishers/organizations:
  • Centers for Disease Control (not CDC),
  • U.S. Department of Agriculture (not USDA).

Where the author and publisher/organization are identical, the publisher name may be abbreviated.

B) DOIs and Web Addresses
Where available (generally for journal articles and some books/book chapters), DOIs (digital object identifiers) must be included.

Web addresses should only be included if the information would otherwise be difficult to find or access or is liable to change (as in databases). Where a web address is given, a date of access is necessary. A web address is never necessary if a DOI is available.

Tables
In manuscripts submitted for review, either embed each table in the text where it is cited or place each table on a separate page following the references. For accepted manuscripts submitted in .doc(x) format, supply each table as a separate spreadsheet (one table per sheet) in an Excel
workbook. Present only the data that should be formatted for print. In LaTeX documents, either embed tables where they are cited or place them after the references.

Number tables consecutively using Arabic numerals in the order in which they appear in the text. All tables must be referred to in the text. Capitalize the word “Table” when citing (e.g., “Table 1,” not “table 1”).

Tables should be self-contained and complement, not duplicate, information contained in the text. Place explanatory matter, including definitions of abbreviations, in a notes section beneath the table. The table, title, and notes must be concise and understandable without reference to the text. If data come from another published or unpublished paper, the original source should be cited in the notes. Use the following standard language to indicate significance:

  • “Single, double, and triple asterisks (*, **, ***) indicate [statistical] significance at the 10%, 5%, and 1% level.”

Use the notes section to explain parentheses, brackets, footnotes, abbreviations, or data descriptions used in each table. Use alphabetical notes (a, b, c, d, e, etc.) as needed. Use asterisks only to identify significance.

Capitalize table and column titles according to the rules for the manuscript title. Column headings should be brief, with units of measurement in parentheses. Parenthetical information in column titles (such as measurements) should be lowercase. Column titles should be bold. All other text (including row labels) should be capitalized in sentence style (only the first word capitalized). Do not use bold, italic, or underlined text in row labels.

Use minimal formatting. Do not use vertical lines to separate columns. Each table must have a consistent number of decimal places. In cases where more than four decimal points are required, scientific notation is preferred.

Figures
In manuscripts submitted for review, either embed figures in the text where they are cited or place each figure on a separate page following the tables.

For accepted manuscripts, figures can either be submitted as individual worksheets (one figure per sheet) in an Excel workbook or as individual image files (acceptable formats are .PNG and .JPG). Individual image files should be greyscale and of high resolution, with a minimum dpi of
300 (600 dpi is preferable for maps and photographs). Maps or photographs must be submitted as separate files. Do not embed figures in a Word document. In LaTeX documents, either embed figures where they are cited or place them after the tables.

Individually submitted figures should be no more than 5 inches wide. All text within the image must be Times New Roman, not bold or italic. Axis titles are 12-point font, sentence case. Axis labels are 10-point font, lowercase. Legends are either 10- or 12-point font, whichever works better. Figure background should be white, and the figure should not have a border.

Figures must be in greyscale to facilitate printing. All references to color (e.g., solid red line, shaded green area, etc.) must be changed to reflect this limitation.

Number figures consecutively using Arabic numerals in the order in which they appear in the text. All figures must be cited in the text. Capitalize the word “Figure” when citing (e.g., “Figure 3,” not “figure 3”). Use of two-part figure numbers (e.g., “Figure 2a” and “Figure 2b”) is discouraged except where all of the parts can fit on a single manuscript page.

Figure titles should be concise and capitalized according to the rules for the manuscript title. Place explanatory matter, including definition of abbreviations, in a notes section beneath the table. If data come from another published or unpublished paper, the original source should be
cited in the notes. It is not necessary to cite “authors’ calculations” (or similar) as a source. Do not place figure title or caption within the figure graphics box.

Style, Grammar, and Punctuation
The Journal of Agricultural and Resource Economics follows the Chicago Manual of Style, 17th ed., by the University of Chicago Press and Garner’s Modern English Usage for style, grammar, and punctuation. The journal uses American English (US) spelling, style, and grammatical
conventions. Where not addressed directly, defer to Webster’s Third New International Dictionary for correct spelling. The following are commonly queried or commonly confused points.

A) Dates

  • Spell out and lowercase centuries (e.g., twentieth century).
  • Spell out and capitalize names of days (e.g., Sunday, Monday) and months (e.g., December, July).
  • When indicating a specific date, use day-month-year (e.g., January 1, 2000). Set off year with commas.
  • When indicating a specific month and year, do not separate the year by a comma (e.g., January 2000).
  • When referring to a span of years, use the full four-year date (e.g., 1994–2004, 1979–1983).
  • When referring to a decade, add an s without an apostrophe (e.g., 1980s)

B) Numbers
As a general rule, use Arabic numerals for whole numbers. Use Arabic numerals with a unit or abbreviation of measure, including currency, proportions, rates, temperatures, percentages, dates, time, pages, and numerical designations such as “model 3.” Use Arabic numerals for all
mathematics where symbols are used, where arithmetic function is discussed (e.g., “divide by 6,” “less than 1,” “significantly different from 0”), and where exponents are used (e.g., 1010). Spell out numbers in the following cases:

  • when the number is below 10 and immediately precedes a non-SI or non-English unit of measure (e.g., “two plants” but “2 m,” “three trees” but “3 ha”);
  • when a number is used as a figure of speech (e.g., “a thousand times no”);
  • when numbers begin sentences (reword sentences where possible to avoid starting with a number or a series of numbers, or end the preceding sentence with a semicolon).

Other numerical issues to keep in mind:

  • Use a comma in numerals of four or more digits (e.g., 1,000; 12,382).
  • For decimal fractions less than 1.00, use a zero in the whole-number position (e.g. 0.01).
  • Follow the same rules as for whole numbers when using ordinals (1st year, but first survey). Do not use superscripts for ordinal numbers (e.g., 1st, not 1st).
  • Use numerals for percentages (unless the percent falls at the beginning of the sentence); the word “percent” should always be a symbol (%). Repeat the percentage sign when indicating a range (e.g., 3% to 5%, 3%–5%).
  • Where series in the text are numbered, use i), ii), iii), etc.
  • Spell out fractions when they stand alone (note hyphen) (e.g., “one-third,” “one-half,” and “two-fifths”).
  • When describing binary variables, use numerals 1 and 0.

C) Capitalization
Capitalization should follow standard rules of English. Only capitalize titles when they immediately precede a personal name (e.g., “Director of Operations Andrew Jones,” but “Andrew Jones, director of operations”).

Capitalize the first word of a full sentence after a colon. Do not capitalize numerical designations such as “model 2,” “experiment 4,” etc.

D) Punctuation
Apostrophe
• Avoid contractions (e.g., can’t, won’t, shouldn’t). Instead, write out (e.g., cannot, will not, should not).
Colon
• Use a colon after “follows” or “following” when introducing a list or thought (e.g., “The expected utility model is as follows:”)
Comma
• Use the serial (i.e., Oxford) comma (e.g., “Crops studied include apple, pear, and cherry.”)
• Which introduces nonrestrictive clauses and is preceded by a comma; that introduces restrictive clauses and is not preceded by a comma (e.g., “the production practice that farmers use extensively” vs. “this production practice, which farmers use extensively, degrades stream quality”).
• A comma should not precede the word “because” unless omitting it would cause confusion (as is sometimes the case when the primary clause is negative). Refer to http://www.chicagomanualofstyle.org/qanda/data/faq/topics/Commas/faq0018.html.
En-dash
• Use en-dash (–) to connect two (juxtaposed, separate) ideas or items, rather than a hyphen (as in a compound adjective). In Word, an en-dash is created using the Ctrl+minus keyboard shortcut.
• Use en-dash for inclusive dates (e.g., July 3–5).
• Use an en-dash in place of a hyphen in a compound adjective when one of its elements consists of an open compound or when both elements consist of hyphenated compounds (e.g. . “pre–World War II,” “non–real estate debts”).
Quotation Marks
• Use double quotation marks around direct quotations.
• Periods and commas precede closing quotation marks; colons, semi-colons, question marks, and exclamation marks follow closing quotation marks (unless they are part of the quotation itself).

D) Hyphenation
In general, do not use a hyphen after a prefix (e.g., co-, non-, re-, sub-, etc.) unless doing so would cause confusion (e.g., “suboptimal,” “comovement,” “nonrestrictive,” but “re-establish).

A compound term is a combination of two or more words that, through use together, have acquired a special meaning. Compound adjectives should generally use hyphens (e.g., “wellknown problems,” “1-year-old cattle”). Use an en-dash in place of a hyphen in a compound adjective when one of its elements consists of an open compound or when both elements consist of hyphenated compounds (e.g., “pre–World War II,” “non–real estate debts”).

Never use a hyphen for a two-word modifier if the first word ends in “ly” or if the word is “very” (e.g., “freshly harvested tomatoes” and “very high frequency”).

Hyphenate compound adjectives before the word they modify but not after the word (e.g., “variable-rate interest,” but “interest with a variable rate.” A compound modifier containing a numeral or spelled out number usually is hyphenated (e.g., “two-thirds majority,” “a 25-minute survey,” and “30-year-old farmer.”)

Hyphenate written-out fractions (e.g., “one-half of respondents,” “three-quarters of the acreage”).

E) Abbreviations
Write all abbreviations in full on their first use followed by their abbreviation (e.g., “ordinary least squares (OLS)”). The exceptions are USDA, U.K., U.S., and EU, which do not need to be spelled out in full on their first use in the text.

Abbreviate U.K. and U.S. when used as adjectives; spell out when used as nouns. Spell out the names of countries, states (in the United States), or provinces (in Canada) when they stand alone (e.g., no city is cited). Use U.S. post office abbreviations for states and provinces when they are given with the city or county. U.S. post office abbreviations are also acceptable as abbreviations in tables and figures.

F) Italics
Italicize scientific genus and species names, titles of published works, and foreign words that have not been naturalized into English. Additionally, italicize a priori, ceteris paribus, ex ante, ex post, i.i.d., and sui generis. Do not use italics to indicate emphasis, quotations, or definitions.
