jru-theory-model
Use when the decision-theoretic representation is the bottleneck for a Journal of Risk and Uncertainty (JRU) manuscript — axioms, functional form, and behavioral content for choice under risk or uncertainty. Strengthens the model; it does not invent evidence or citations.

# Theory and Model Craft (jru-theory-model)
## When to trigger
- The paper proposes or adopts a preference representation (utility + probability weighting, an ambiguity functional) but its **axiomatic foundation** or **behavioral content** is unclear
- A functional form is asserted (CRRA + Prelec weighting, α-MEU, smooth ambiguity) without saying what it rules out
- A referee asks "what does your model predict that EU does not?" and the draft has no crisp answer
- The model is being used to interpret experimental or empirical results but its parameters are not behaviorally interpretable
## The JRU theory bar
JRU is the home of decision theory under risk and uncertainty, so a model is judged on three things at once: an **axiomatic basis** (what preference conditions characterize the representation), a **functional form** that is tractable and identifiable, and **behavioral content** (the model must forbid some observable choices — a representation that fits everything explains nothing). Theory here is rarely art-for-art's-sake; even an axiomatization is expected to connect to measurable behavior, because JRU's readership lives at the theory–experiment–empirics interface.
