Where the words come from
The definition of fiscal policy, expansionary and contractionary fiscal policy and the channels through which each works — Principles of Economics 2e, OpenStax, licensed CC BY 4.0. https://openstax.org/books/principles-economics-2e/pages/30-4-using-fiscal-policy-to-fight-recession-unemployment-and-inflation and https://openstax.org/books/principles-economics-2e/pages/28-3-how-a-central-bank-executes-monetary-policy. Changes: "federal" spending and grants to states dropped; "payroll taxes" dropped; the US 2009 stimulus and party-political paragraph dropped and condensed to "a political choice"; the card definitions joined from 2e's "increases the level of aggregate demand, through either increases in government spending or reductions in tax rates" and its recession and overheating-economy cases, and the contractionary one from "federal spending cuts or tax increases"; the UK Budget and the examples are ours; British spelling.
HM Treasury's role and the Office for Budget Responsibility's forecasts — GOV.UK (HM Treasury) and the Office for Budget Responsibility, Open Government Licence v3.0. https://gov.uk/government/organisations/hm-treasury and https://obr.uk/about-the-obr/what-we-do/. Changes: "maintaining control over public spending" to "controls public spending"; the OBR's description of its twice-yearly five-year forecasts condensed to the Budget forecast.
