JUE referees are urban economists; they know the canonical frames and will test whether you have advanced one. Anchor the contribution in the specific strand you move, then state the delta precisely.
| Strand | The frame referees hold | What counts as moving it |
|---|---|---|
| Agglomeration & productivity | Marshall (sharing/matching/learning); Combes–Gobillon density-wage elasticity; sorting vs true agglomeration | new source of exogenous density variation; decomposing sorting from spillovers; new mechanism |
| Spatial equilibrium | Rosen–Roback; amenity capitalization; Diamond-style sorting | a quantitatively new wedge, amenity, or constraint in the equilibrium |
| Housing supply & prices | Glaeser–Gyourko; Saiz supply elasticity; regulation/land use | new supply-constraint measurement; causal effect of regulation; capitalization design |
| Quantitative spatial models | Ahlfeldt–Redding–Sturm–Wolf; Allen–Arkolakis; market access | new data discipline on parameters; new counterfactual margin |
| Neighborhood effects & mobility | MTO; Chetty–Hendren place effects | new identification of place vs selection; new policy lever |
| Place-based policy | enterprise/opportunity zones; transport infrastructure | credible spillover-aware evaluation; welfare incidence |
| Local public finance | Tiebout sorting; capitalization of local taxes/services | new test of sorting; fiscal incidence in space |
A reduced-form JUE paper increasingly has to speak to the quantitative-spatial-model (QSM) literature even when it does not estimate one. If your estimate is an elasticity or a magnitude that QSMs need as an input (migration, commuting, housing-supply, or agglomeration elasticity), say so — "our reduced-form estimate disciplines the [X] elasticity that ARSW-style models calibrate." This frames a clean reduced-form result as a contribution to structural work and widens the audience. Conversely, a QSM paper must position against the reduced-form estimates its parameters rest on, not only against other models.
The "why JUE" question is a positioning task, not just a venue choice. One sentence in the introduction should make the fit obvious to the editor:
Urban economists hold the field's foundational results precisely, and a miscited or misattributed canon erodes credibility on page one. Get the anchors right for your strand: Rosen and Roback for amenity capitalization in spatial equilibrium; Glaeser and Gyourko (with Saiz on supply elasticity) for housing supply constraints; Combes and Gobillon for the density-wage elasticity and the sorting-vs-agglomeration distinction; Ahlfeldt–Redding–Sturm–Wolf and Allen–Arkolakis for quantitative spatial models; Chetty–Hendren and the MTO literature for neighborhood effects. Engage these on their assumptions, not as decorative citations, and the urban-economics referee reads you as a member of the conversation.
A paper estimates the effect of minimum-lot-size zoning on house prices. Weak positioning: "the literature has not studied lot-size zoning." Strong JUE positioning: anchor in Glaeser–Gyourko supply-constraint work and Saiz elasticities, state that prior work measures aggregate regulation indices while this paper isolates one regulatory margin with a boundary design, and note the estimated supply response disciplines the housing-supply elasticity used in spatial-equilibrium models. The delta — a causal, single-instrument estimate that feeds QSM calibration — is one an urban economist accepts as new.
The single most-read positioning unit is the "contribution paragraph" near the end of the introduction. It should run: closest work and its limit → your variation/mechanism/data → the delta in one sentence → why it matters for cities. Keep it to one paragraph; a JUE referee who has to hunt across the intro for the contribution reads that as a sign the author is unsure what it is. Front the delta, not the apparatus.
