Le document pr\u00e9sente une analyse r\u00e9trospective de la loi f\u00e9d\u00e9rale am\u00e9ricaine \u00ab One Big Beautiful Bill Act of 2025 \u00bb (OBBBA), \u00e0 l\u2019aide de l\u2019outil CAT (U.S. Code Analysis Tool) d\u00e9velopp\u00e9 par le centre de recherche RAND. L\u2019OBBBA a proc\u00e9d\u00e9 \u00e0 634 modifications r\u00e9parties sur 20 titres du Code des \u00c9tats-Unis, dans un contexte o\u00f9 la forte interconnexion des dispositions l\u00e9gislatives rend difficile une \u00e9valuation rapide de leurs effets.<\/p>\n
L\u2019outil CAT cartographie les modifications apport\u00e9es au Code sur un graphe de dispositions et de renvois crois\u00e9s. Il permet d\u2019identifier les articles tr\u00e8s connect\u00e9s, les dispositions nouvellement cr\u00e9\u00e9es ou supprim\u00e9es, celles qui sont fortement r\u00e9\u00e9crites ou dont les relations avec d\u2019autres parties du Code sont substantiellement modifi\u00e9es. L\u2019objectif est de faciliter une \u00ab triage \u00bb rapide des textes l\u00e9gislatifs en compl\u00e9ment d\u2019autres outils utilis\u00e9s au niveau f\u00e9d\u00e9ral, tels que les chiffrages du Congressional Budget Office (CBO), les synth\u00e8ses par domaine de politique publique ou de simples comptages d\u2019amendements. CAT met l\u2019accent sur la place des modifications dans la structure globale du Code et sur leur impact potentiel sur l\u2019interpr\u00e9tation des textes, la gestion des programmes et leur mise en \u0153uvre.<\/p>\n
Dans cette \u00e9tude de cas, les auteurs ont reli\u00e9, lorsque c\u2019\u00e9tait possible, les dispositions signal\u00e9es par CAT aux estimations budg\u00e9taires du CBO, afin de fournir un contexte financier aux changements identifi\u00e9s. L\u2019analyse montre que CAT rep\u00e8re \u00e0 la fois les mesures les plus visibles de l\u2019OBBBA (notamment en mati\u00e8re de Child Tax Credit et une nouvelle d\u00e9duction fiscale pour les pourboires qualifi\u00e9s) et des modifications plus discr\u00e8tes mais potentiellement importantes pour la mise en \u0153uvre des politiques. Ces derni\u00e8res incluent des changements concernant les exigences des plans d\u2019\u00c9tat Medicaid, des restrictions relatives au logement assist\u00e9 et des r\u00e8gles applicables \u00e0 certains programmes agricoles.<\/p>\n
Les acteurs principaux mentionn\u00e9s sont le Congr\u00e8s des \u00c9tats-Unis (auteur de l\u2019OBBBA), le Congressional Budget Office (charg\u00e9 des estimations budg\u00e9taires), et RAND, institution de recherche \u00e0 but non lucratif qui a d\u00e9velopp\u00e9 l\u2019outil CAT et publi\u00e9 ce rapport. Les travaux de RAND sont soumis \u00e0 une \u00e9valuation scientifique rigoureuse et n\u2019engagent pas n\u00e9cessairement la position de ses clients ou financeurs. L\u2019utilisation de CAT appara\u00eet comme un outil m\u00e9thodologique potentiellement pertinent pour le suivi rapide de r\u00e9formes l\u00e9gislatives complexes, notamment lorsque celles-ci touchent \u00e0 des dispositifs sociaux, fiscaux, de sant\u00e9 ou d\u2019emploi aux multiples effets en cha\u00eene.(contenu r\u00e9sum\u00e9 en fran\u00e7ais par l’IA)\u00a0Lire la
