Fiscal policy deals with government taxation and spending decisions. The key instruments of fiscal policy are the budget, taxation, public expenditure, public revenue, public debt, and fiscal deficit. Fiscal policy can be either expansionary, which stimulates economic growth through tax cuts or increased spending, or contractionary, which slows growth through tax increases or spending cuts. The current US fiscal policy has led to massive government debt levels, with mandatory spending on programs like Social Security, Medicare and Medicaid accounting for most of the budget. The objectives of fiscal policy include mobilizing resources, reducing inequality, price stability, employment generation, balanced regional development, improving the balance of payments, increasing national income, developing infrastructure, and earning foreign exchange.
