# kaal:position:2026-08-08-308

**Affirmed position.** Bougherara, Muller, and Teyssier qualify Kaal's controlled comparison. They explain that experimental economics isolates a causal effect by changing one environmental or institutional feature at a time. Within-subject designs can hold the participants constant across treatments, but they also create an order-effect risk. This supports the methodological rationale for keeping the labor force and work assignment fixed while varying the institution. The correspondence remains narrow. The chapter states a general experimental principle. It does not verify that Kaal's cohort, tasks, or timing were actually held constant. It also does not establish randomization, counterbalancing, independence across conditions, or the validity of any later estimate.

**Holds when.**

- The response is limited to the two evidence-bound passages and the one mapped Kaal claim.
- External evidence level: complete public NCBI Bookshelf chapter with DOI, authors, date, section-bound evidence, and immutable HTML bytes.
- Mapping review tier: independent substantive scholarly-growth qualification.
- The chapter states a general principle of experimental design. It does not audit Kaal's cohort, assignments, execution, or data.
- Holding the same participants across treatments removes one sample-comparability problem but creates order and carryover risks.
- The source does not establish randomization, counterbalancing, independence across conditions, or the validity of any later estimate.
- Semantic Scholar rate-limited the general search and six inherited identity refreshes. Two DOI lookups returned no current record.
- The bounded review used fresh English, German, and Spanish Crossref and OpenAlex searches, Semantic Scholar, arXiv, NCBI Bookshelf, Crossref DOI, OpenAlex DOI, and web literature.
- The chapter reports DOI 10.35690/978-2-7592-3664-0/c4, but the DOI resolver returned HTTP 404 in this run. The public position therefore uses the verified HTTP 200 NCBI Bookshelf URL.
