Explanation:

Fiscal policy in economics refers to the use of government expenditures (spending) and revenues (taxation) in order to influence macroeconomic conditions such as Aggregate Demand (AD), inflation, and employment within a country. Fiscal policy is in relation to the Keynesian macroeconomic theory by John Maynard Keynes.

A fiscal policy affects combined demand through changes in government policies, spending and taxation which eventually impacts employment and standard of living plus consumer spending and investment.

Generally, the national government of a country might use a contractionary policy to slow down the economy when inflation is high and gross domestic product (GDP) is growing too.

Hence, a contractionary fiscal policy is a policy that is typically used by the government to reduce aggregate demand by decreasing government purchases.

Aggregate demand (AD) can be defined as the total quantity of output (final goods and services) that is demanded by consumers at all possible price levels in an economy at a particular time.

An aggregate demand curve gives a negative relationship between the aggregate price level for goods or services and the quantity of aggregate output demanded in an economy at a specific period of time.
