Austerity is a set of political-economic policies that aim to reduce government budget deficits through spending cuts, tax increases, or a combination of both. There are three primary types of austerity measures: higher taxes to fund spending, raising taxes while cutting spending, and lower taxes and lower government spending. Austerity measures are often used by governments that find it difficult to borrow or meet their existing obligations to pay back loans. The measures are meant to reduce the budget deficit by bringing government revenues closer to expenditures. Proponents of these measures state that this reduces the amount of borrowing required and may also demonstrate a government's fiscal discipline to creditors and credit rating agencies and make borrowing easier and cheaper as a result.
