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.

Basically, an expansionary fiscal policy will cause the total increase in aggregate demand to be greater than the initial increase in aggregate demand due to the multiplier process.

Hence, when the interest rate in an economy decreases, it is likely the result of either an expansionary practice or an open market purchase of securities by the Federal Reserve System (Fed).

According to the Keynesian theory, government spending or expenditures should be increased and taxes should be lowered when faced with a recession, in order to create employment and boost the buying power of consumers
