aeja-robustness

Use when an American Economic Journal: Applied Economics (AEJ: Applied) manuscript's headline estimate must be shown to survive specification, sample, and inference choices before submission or in an R&R. Builds the robustness suite a sophisticated referee expects; it does not establish the primary identification (aeja-identification) or format the exhibits (aeja-tables-figures).

# Robustness Suite (aeja-robustness)

## When to trigger

- The main estimate is in hand and you need to show it is not an artifact of one specification
- A referee asks "is this robust to [alternative controls / sample / functional form / inference]?"
- The result depends on a bandwidth, a clustering choice, or a sample-selection rule that could be questioned
- You suspect specification-search concerns and want to pre-empt them

## The AEJ: Applied robustness bar

AEJ: Applied referees probe whether the headline number is **stable, honestly inferred, and not the product of researcher degrees of freedom**. Robustness here is not a wall of regressions — it is a **targeted set of checks each tied to a specific threat to the design**. Map every plausible objection to the one check that answers it, and report the checks so the reader sees the estimate barely moves.
