aeri-theory-model

Use when a model — a full theory paper's argument or the structural/conceptual scaffolding behind an empirical AER: Insights short-format manuscript — needs to be made minimal, so it carries the single insight in a few pages. Keeps only what the insight requires; it does not develop a general framework.

# Theory / Model — Minimal to Carry One Insight (aeri-theory-model)

## When to trigger

- A theory paper's single result (a theorem, an impossibility, a sharp comparative static) needs a tight model
- An empirical paper carries a structural or conceptual model that has grown beyond what the result needs
- The model section is eating the word budget that the result and identification need
- A referee might ask "why all this machinery for one point?"

## The AER: Insights modeling discipline

AER: Insights rewards a **single, surprising, clean theoretical or modeling insight** delivered with **the smallest model that produces it**. The question is never "is the framework general?" but "**what is the most economical model whose one result is important and surprising?**" Generality, extensions, and robustness of the modeling go to the Supplemental Appendix; the main text states the assumptions, the one key result, and the intuition. A theory paper here is *short and pointed*, the opposite of a foundational framework paper for AER or a field journal.

## Two cases
