How to Write a Journal of Economic Theory Cover Letter (With Template)
The Journal of Economic Theory cover letter has one job: make the theoretical contribution legible as an economics result and route the paper to the right co-editor. Here is the template, the required declaration, and the openers that work.

Quick answer: A strong Journal of Economic Theory cover letter (Elsevier, ISSN 0022-0531) does three things in one page: it names the economic question first, states the theorem-level increment over the closest existing result, and routes the paper to the right co-editor by field area. It also carries the exclusive-submission declaration. If the letter restates the abstract or leads with formal machinery, it does not do the editorial job JET needs before a co-editor commits referee time.
Why the cover letter decides routing at Journal of Economic Theory
The real question is not "did I attach a cover letter?" It is "could a JET co-editor outside my exact subfield see, after one page, that this theorem is an economics result worth refereeing?" JET assigns each submission to a co-editor by area, so the letter is the first routing and significance argument the journal reads.
Journal of Economic Theory submission readiness check before you open the Editorial Manager slot.
JET is the broad-interest theoretical-economics journal at Elsevier. Submissions arrive across mechanism design, game theory, decision theory, social choice, general equilibrium, market design, and theory-grounded macro and finance. That breadth means the handling co-editor may not work in the narrowest niche of your model. The cover letter has to translate the formal result into an economics result a theory-literate co-editor can judge fast, and to signal which area should handle it.
How this page was reviewed: the evidence basis is Elsevier's published JET guide for authors, Elsevier's general cover-letter guidance, the JET editorial board structure, and the recurring editorial triage pattern we see in our pre-submission review work. We did not access a private JET editorial account; the routing and declaration guidance below is built from public Elsevier materials and anonymized Manusights pre-submission manuscript observations. Use this page when the question is the JET cover letter itself, before you submit.
The three jobs every JET cover letter must do
Letter job | What to say | What to avoid |
|---|---|---|
Name the economic question | State the economic problem the theorem answers, in plain language | Opening with "Consider a class of..." before any economic question |
State the increment | Name the precise weakening, strengthening, or generalization over the nearest existing theorem | "We extend the model to N players" with no new economic insight |
Route the paper | Name the field area (mechanism design, decision theory, macro theory) so the editor can assign a co-editor | Leaving routing to the editor to infer from the proofs |
This table is Manusights editorial framing, not a JET-published checklist.
The order matters. JET co-editors scan for economics-legibility, then for the theorem-level contribution, then for fit versus the closest theory venues. A letter that names the question, the increment, and the area in that sequence is faster to route and faster to send out.
Journal of Economic Theory cover letter template
Use this as a decision framework, not a script to paste without editing. Replace every bracketed field with your own text.
Dear Editor,
We are pleased to submit our manuscript, "[MANUSCRIPT TITLE]," for
consideration at the Journal of Economic Theory.
This paper addresses the economic question of sTATE THE ECONOMIC PROBLEM IN ONE PLAIN SENTENCE, NOT THE THEOREM. Our main result shows that
sTATE THE THEOREM AS AN ECONOMICS RESULT, IN ACTIVE VOICE.
The contribution over the existing theory is precise: Theorem 1
[STRENGTHENS / WEAKENS THE ASSUMPTIONS OF / GENERALIZES] the closest prior
result in [NEAREST PAPER, AUTHOR AND YEAR], which lets us conclude
[THE NEW ECONOMIC IMPLICATION THE PRIOR RESULT DID NOT DELIVER].
The work fits the [MECHANISM DESIGN / DECISION THEORY / MACRO THEORY /
GAME THEORY] area of the journal. We considered [THEORETICAL ECONOMICS /
ECONOMETRICA / GAMES AND ECONOMIC BEHAVIOR] and believe JET is the right
venue because [ONE SENTENCE ON BROAD THEORETICAL INTEREST OR APPLIED REACH].
This manuscript is original, has not been published, and is not under
consideration for publication elsewhere. All authors have read and
approved the submission.
Sincerely,
[CORRESPONDING AUTHOR NAME, AFFILIATION, EMAIL]The template enforces discipline. If the letter grows because you keep adding proof detail or defensive context, the contribution paragraph is probably not sharp enough yet.
The exact non-duplication declaration to use
JET runs through Elsevier, so the standard exclusive-submission declaration applies. Use this verbatim sentence in the letter:
This manuscript is original, has not been published previously, and is not under consideration for publication elsewhere.
Pair it with the authorship line:
All authors have read and approved the submission, and there are no other persons who satisfied the criteria for authorship but are not listed.
Those two sentences cover originality, exclusivity, and authorship approval in one place. The declaration of competing interest and the data or code availability statement are separate: enter them in the submission system or place them in the manuscript, not in the cover letter body.
A JET opener that routes versus one that stalls
The single most decision-relevant choice is the first sentence. Compare these two openers for the same paper.
Weak opener:
We study a class of mechanisms in which a principal faces agents with heterogeneous private types, and we characterize the set of incentive-compatible allocations under a regularity condition.
Why it stalls: the co-editor reads three lines of formal setup before learning what economic question is at stake, so routing and significance both have to be reconstructed from inside the model.
Strong opener:
Whether a revenue-maximizing principal should screen heterogeneous agents with a menu or a single posted price has stayed unresolved when types are correlated. Here we show that a menu strictly dominates posted pricing precisely when the correlation crosses an explicit threshold, which gives a testable rule for when richer mechanisms are worth their complexity.
Why it routes: the economic question is named first, the result reads as an economics conclusion, the increment is concrete, and the co-editor can already place the paper in the mechanism-design area.
Article types and how the cover letter shifts
JET publishes full theoretical research articles as its primary type, and it has historically carried shorter Notes for compact theoretical results that do not need a full-length treatment. The cover letter framing changes with the type.
Article type | Cover letter emphasis | What to make explicit |
|---|---|---|
Research Article | Full theorem-level contribution and venue fit | The increment over the nearest 3 to 5 theorems, plus the economic implications |
Note | Why the result is correct, self-contained, and worth a short slot | That the result is compact, complete, and not a fragment of a larger paper |
Revision or resubmission | The prior decision context and what changed | Reference any prior editor discussion in the letter; route to the same area |
Article-type names follow Elsevier JET conventions; confirm current types on the journal's guide for authors.
If JET has consolidated to research articles only in the current guide for authors, default to the research-article framing and drop the Note row. The routing and declaration logic does not change.
Co-editor suggestion, exclusive submission, and what stays out of the letter
JET assigns each submission to a co-editor by field area, which is why the routing sentence is load-bearing. You can write that the paper fits a specific area and point to the relevant co-editor on the journal's editorial board page. Per our editorial policy, verify the current co-editor for that area on the journal's own editorial board page before quoting any name in the letter, because rosters change.
Elsevier's published cover-letter guidance is explicit about what does NOT belong in the letter body:
- Funding information is entered in the submission system, not the letter.
- Author declarations (competing interest, ethics) are completed separately, then mirrored in the manuscript.
- Suggested or excluded reviewers are entered in the Editorial Manager form, not the cover letter, and JET will request them if needed. If you do suggest referees, 2 to 4 reviewers is a normal range, and you can name reviewers to exclude where a genuine conflict exists. Suggested reviewers are not required in the cover letter body.
JET is published by Elsevier under a hybrid model and submits through Editorial Manager at Editorial Manager submission portal: subscription publication carries no submission fee and no APC, while the gold open-access option carries an Elsevier APC currently around $3,500 to $4,500 USD. Do not confuse this with Theoretical Economics, the Econometric Society's open-access alternative, which requires Econometric Society membership and a submission fee. Naming the wrong fee structure in a cover letter signals you have not read the venue you are submitting to.
If your letter references a closely related prior result in the journal, cite it precisely. Representative recent JET DOIs you can model the citation format on include 10.1016/j.jet.2023.105456, 10.1016/j.jet.2024.105789, and 10.1016/j.jet.2024.105892. Confirm the specific paper, author, year, and theorem number against the journal's own issue archive before you cite it in the letter.
The editor's view at desk
Here is what a JET co-editor is actually doing in the first minutes. They are deciding whether the main theorem is legible as an economics result, which area should own the paper, and whether the contribution clears the bar without their having to reconstruct it from the proofs. A letter that names the economic question, states the precise increment, and points to the right area lets the co-editor make all three calls in one reading.
A letter that opens with the formal setup forces the co-editor to do the author's framing work before any of those decisions, and that friction is exactly where otherwise-strong theory papers lose momentum at the desk.
In our pre-submission review work with Journal of Economic Theory submissions
In our pre-submission review work with Journal of Economic Theory submissions, the cover letter fails in three named rejection patterns that consistently precede desk friction before a co-editor sends the paper out. These are anonymized Manusights pre-submission manuscript observations matched against Elsevier's published JET guidance and recent issue patterns, and they map to the editorial triage pattern JET's mathematical-rigor-plus-theoretical-advance bar produces. JET does not publish manuscript-level desk-rejection reasons, so treat the patterns as testable checks, not journal statistics.
The theorem-first letter that buries the economic question. Across our Journal of Economic Theory reviews, the most common cover-letter failure is a first paragraph that states the formal result before naming the economic question. The letter opens with the model class, the payoff structure, and the equilibrium concept, and the economics arrives only after the proof sketch.
A JET co-editor reads the opening to decide whether the theorem is an economics result; when the letter leads with machinery, routing and significance both have to be inferred from inside the proof. The fix is testable against your own draft: the first sentence of the cover letter must name the economic question (which mechanism, which equilibrium selection, which auction format, which matching rule), and the theorem statement should follow in economics vocabulary.
The increment paragraph that cites the literature but never states the delta. In our Journal of Economic Theory review work, manuscripts routinely cite the nearest theorems but never name the precise increment over them. The letter says the paper "builds on" or "extends" prior results without stating whether it weakens an assumption, strengthens a conclusion, generalizes the payoff or signal structure, or introduces a new equilibrium concept.
A co-editor cannot assess a contribution they have to reconstruct, so the paper waits. The testable fix is a single sentence in the letter naming the closest result by author and year, the exact weakening or strengthening, and the new economic conclusion the prior result did not deliver. Run this against your introduction's contribution paragraph and proofs: if the theorem statement and the cover-letter increment claim do not match, the letter is overpromising.
The venue-misrouting letter that defaults to JET without naming the alternative. The third pattern we see across pre-submission reviews is a cover letter that defaults to JET without addressing the JET-versus-Theoretical-Economics choice, the most consequential routing decision for pure-theory work. Decision theory with axiomatic foundations, mechanism design with structural elegance, and information design often fit Theoretical Economics, while theory with applied, quantitative, or macro components and broader-audience reach fits JET.
A letter that does not name the area or justify JET over Theoretical Economics, Econometrica, or Games and Economic Behavior leaves the co-editor to guess the routing. The fix is a routing sentence that names the field area, names the closest alternative venue, and gives one reason JET is right, which also lets the co-editor assign the correct area co-editor faster.
These three are fixable before you submit. A JET cover letter and theorem-increment check scores whether the economic question leads, the increment is stated, and the routing is clear in 1 to 2 minutes.
Final cover letter checklist
Run this before you upload:
- the first sentence names the economic question, not the theorem
- the main result is stated as an economics conclusion in active voice
- the increment over the nearest existing theorem is stated precisely (weaker assumption, stronger conclusion, or new concept)
- the routing sentence names the field area and the closest alternative venue
- the exclusive-submission declaration and the all-authors-approved line are present
- funding, declarations, and suggested reviewers are in the submission form, not the letter
- the letter stays within one page and does not drift into proof detail
Submit If / Think Twice If
Submit to JET with confidence if:
- the cover letter's first sentence names an economic question, and the theorem reads as an economics conclusion
- you can state the precise increment over the nearest existing theorem in one sentence (weaker assumption, stronger conclusion, or new equilibrium concept)
- the routing sentence names the field area and justifies JET over Theoretical Economics, Econometrica, or Games and Economic Behavior
- the exclusive-submission declaration and the all-authors-approved line are present, and declarations live in the submission form, not the letter
Think twice before submitting if:
- the increment sentence only works with hedging like "we extend the model to N players" and never names a new economic implication, which usually means the result is a small extension better suited to a Note or a field journal
- the abstract and cover letter open with the model class before naming the economic question, so a co-editor has to reconstruct the significance from the proofs
- the routing keeps defaulting to JET only because it is familiar, when decision theory or mechanism design with axiomatic foundations would fit Theoretical Economics more naturally
- the proof appendix still has hand-waved lemmas or assumptions introduced after the theorem, because a confident cover letter cannot rescue an incomplete proof
If you cannot write the increment sentence without hedging, that is useful information: read five recent papers from JET and five from Theoretical Economics before you commit. The cover letter is diagnostically useful here, because it forces you to articulate the contribution and the venue fit before a co-editor has to. Run a final JET manuscript readiness check on the package before you upload.

What to read next
Frequently asked questions
Journal of Economic Theory accepts a cover letter at the Editorial Manager upload step, and a short, focused letter helps. Elsevier's own guidance asks the letter to state the aim and main finding, explain the journal fit, and name the contribution. Keep it to one page. Funding, declarations, and suggested reviewers are entered in the submission form, not the letter body.
Keep it to one page, roughly 250 to 400 words. JET co-editors read the letter to decide whether the theorem is an economics result, not only a mathematics result, and to route the paper. Lead with the economic question and the theorem-level increment over the closest existing result. Do not restate the abstract.
JET assigns each paper to a co-editor by field area, so naming the field of the contribution helps routing. You can write that the paper fits the mechanism-design, decision-theory, or macro-theory area and point to the relevant co-editor on the journal's editorial board page. Verify the current co-editor for that area on the journal's own editorial board page before naming anyone.
State that the manuscript is original, has not been published, and is not under consideration elsewhere, and that all authors have approved the submission. This exclusive-submission declaration is standard for Elsevier journals. The declaration of competing interest and the data or code availability statement are completed in the submission system or the manuscript, not the cover letter body.
Open with the economic question, then the theorem-level increment over the nearest existing result, then the venue fit versus Theoretical Economics or Econometrica. Avoid openers that start with the formal setup such as 'Consider a class of mechanisms' before naming the economic question the paper answers.
