Fiscal policy uses government spending and taxation to influence the economy. It aims to achieve economic stability without inflation or deflation. The government collects revenues through taxes, fees, fines, and loans, then spends money on productive investments like infrastructure and non-productive services like education and health. The budget shows estimated receipts and expenditures. Fiscal policy can be neutral, expansionary, or contractionary depending on whether spending equals, exceeds, or is less than tax revenue. While fiscal policy aims to evenly distribute wealth and resources, limitations include inadequate data and delayed decision-making.
