Template assessment

The public-body-by-product purchase panel has too little common adoption-baseline and untreated fixed-effect support. The common-sample preparation leaves no estimable comparison; the source-sample coefficient itself reproduces.

No comparison point or homogeneity-test decision is assigned to this paper.

Source coefficient	Template on source sample	Source N	Template source-sample N
-0.27497	-0.27497	3101	3101

Source-to-template coefficient difference: 4.53e-14, in original outcome units.
