Here the claim is that a statistical test, which lets the data pick any threshold, does not find 90% in that same data. This bears on how far fiscal policy debates can lean on a single debt ceiling figure. The paper also adds that lower thresholds may exist and that debt may be linked to weaker growth at moderate levels.","findings":["The nonlinear relation between debt and growth in the Reinhart–Rogoff data is not robust.","With caution, a negative link between central government debt and growth may begin at about 20% of GDP, and for general government debt at about 50%.","Country estimates vary widely: for some countries, including the United States, a nonlinear negative link appears at about 30% of GDP, while for others no nonlinearity is found."],"terms":[{"term":"econometric","means":"Using statistical methods to test relationships in economic data."},{"term":"public debt threshold","means":"A level of government debt, as a share of GDP, beyond which the relationship with economic growth is said to change."},{"term":"Reinhart–Rogoff data","means":"The cross-country data-set on public debt and growth compiled by Carmen Reinhart and Kenneth Rogoff, used in their influential work on debt and growth."}],"basis":"abstract","abstractFrom":"openalex","model":"claude-sonnet-5-5","writtenAt":"2026-10-12T07:32:12.207Z","version":"context/0.2"},"summary":{"status":"written","at":"2026-10-12T07:32:12.207Z","attempts":1,"model":"claude-sonnet-5-5","why":null},"note":"Machine-written context to help a reader: it is not evidence, it moves no number, and it may be wrong.
