Two preliminary quarterly real-GDP declines support a narrow descriptive statement and trigger investigation. They do not mechanically reproduce the NBER committee's U.S. chronology.

The reviewer asks about breadth, depth, duration, real income, payroll and household employment, industrial production, sales, monthly timing, revisions, and the authority whose definition is being invoked. A current forecast and a later peak-to-trough date are different products.

Even a well-supported recession date does not identify cause. A claim about policy, credit, energy, disease, inventories, or expectations needs a causal design and competing explanations. A portfolio, budget, or policy response also needs objectives, alternatives, uncertainty, constraints, and authority.
