What it does

Jleo Theory Model is an agent skill from brycewang-stanford/Awesome-Journal-Skills. Use when building or sharpening the formal model for a Journal of Law, Economics, and Organization (JLEO) manuscript — transaction-cost, incomplete-contracts / property-rights, principal-agent, or political-agency models of institutions and organizations. Right-sizes and disciplines the model; it does not run the empirics (jleo-identification, jleo-robustness).

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Journal-specific Claude Code/Codex skill packs covering mainstream journals — AER, QJE, Nature, Cell, 管理世界, 经济研究 & 200+ more — your fast track to getting published. | 覆盖主流期刊的… The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit 932eb23. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jleo Theory Model loads about 1.5k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 699 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when building or sharpening the formal model for a Journal of Law, Economics, and Organization (JLEO) manuscript — transaction-cost, incomplete-contracts / property-rights, principal-agent, or political-agency models of institutions and organizations. Right-sizes and disciplines the model; it does not run the empirics (jleo-identification, jleo-robustness).

Theory & Model Craft (jleo-theory-model)

When to trigger

  • A verbal institutional argument needs to be formalized into testable predictions
  • A formal model exists but its assumptions or comparative statics are not tied to the institution it describes
  • A referee asks "what is the model actually adding beyond the intuition?"
  • The paper is a pure-theory JLEO submission and must deliver a sharp, novel institutional mechanism
  • An empirical paper needs a minimal model to define the estimand and generate the sign predictions it tests

The JLEO modeling tradition

JLEO is unusual in welcoming both standalone formal theory and empirical work disciplined by a model, but in both cases the model must be a model of an institution or organization, in one of the house lineages:

  • Transaction-cost economics (Williamson): asset specificity, uncertainty, frequency → governance choice (market / hybrid / hierarchy). The model's job is to predict which governance form economizes on transaction costs.
  • Incomplete contracts / property rights (Grossman–Hart–Moore): residual control rights, non-contractible investment, ownership allocation. The model predicts who should own what.
  • Principal–agent / mechanism design: incentive provision under moral hazard or adverse selection inside organizations and contracts.
  • Positive political economy / political agency: legislators, courts, bureaucrats, voters as strategic actors; separation of powers, delegation, credible commitment, agenda control.

Pick the lightest model that delivers the institutional prediction; a model that adds notation but no new comparative static is decorative and JLEO referees say so.

Right-sizing the model

The model's jobRight amountWhere it goes
Name and discipline a mechanisma few equations / a 2-type or 2-period setupshort framework section
Generate sign predictions to test empiricallya tractable comparative-statics modelframework before results; tested in data
Adjudicate a governance/ownership comparisona TCE or GHM model with a clear cutoffdedicated theory section
Deliver a full institutional result (theory paper)a complete model with proofsthe paper's core, proofs in appendix

Craft moves JLEO referees reward

  1. Tie every assumption to the institution. An assumption that is mathematically convenient but institutionally implausible (e.g., fully contractible quality in a hold-up story) draws fire. Justify the non-contractibility, the timing, the information structure from the institution.
  2. Make the comparative statics the deliverable. State the testable predictions before the data appear (no HARKing the theory). For a theory paper, state which prediction is the surprising one.
  3. Earn the equilibrium concept. If you use a refinement (e.g., a particular off-path belief, a specific bargaining protocol), say why that protocol fits the institution and what changes under alternatives.
  4. Show robustness of the mechanism. Demonstrate the key result is not an artifact of a knife-edge assumption; relegate the general case to an appendix if it clutters.
  5. Connect to the empirics (if mixed). The model should define the estimand the empirical section recovers, and the parameters should map to measurable institutional features.

Checklist

  • The model is a model of a specific institution/organization in a JLEO lineage (TCE / GHM / agency / PPE)
  • Every substantive assumption is justified from the institutional setting, not just tractability
  • The testable comparative statics are stated before the empirics; the surprising prediction is flagged
  • The equilibrium concept / bargaining protocol fits the institution and alternatives are discussed
  • For theory papers: proofs complete and in the appendix; the main text carries intuition
  • For mixed papers: the model defines the estimand and maps parameters to measurable features

Anti-patterns

  • A "model" section that adds notation but no new prediction or governance comparison
  • Assuming away the non-contractibility / specificity that the institution actually exhibits, to gain tractability
  • Comparative statics derived after seeing the empirical results (HARKing the theory)
  • Borrowing an off-the-shelf principal-agent setup with no institutional content specific to the paper
  • A knife-edge result presented as the headline with no robustness of the mechanism

Worked vignette (illustrative)

A paper asks why public agencies use long-term sole-source contracts despite the apparent loss of competition. A bare auction model says competition is always better. A JLEO model adds non-contractible quality and relationship-specific investment: under high specificity, the long-term relationship sustains quality that competitive re-bidding would destroy, so sole-sourcing economizes on transaction costs above a specificity threshold. The comparative static — sole-sourcing rises with specificity and with the cost of quality verification — is then taken to procurement data, where the model defines exactly what to measure.
