Government spending is a component of real GDP: Y = C + I + G + NX This makes it appear as though increases in government spending increase output—and hence other relevant economic variables like employment. However some economists argue that government spending simply shifts employment from one group to another—it does not increase total employment. • This debate was particularly important after the 2007-2009 recession: can the government use discretionary fiscal policy to increase employment?

(State taxes and spending are not generally aimed at affecting national-level objectives.) Some forms of government spending and taxes automatically increase or decrease along with the business cycle; these are automatic stabilizers. Example: Unemployment insurance payments are larger during a recession. Discretionary fiscal policy, on the other hand, refers to intentional actions the government takes to change spending or taxes

Federal purchases consist of defense spending and “everything else”, like salaries of FBI agents, operating national parks, and funding scientific research. Around half of federal expenditures are spent on transfer payments, like Social Security, Medicare, and unemployment insurance. The rest is spent on grants to state and local governments to support their activities, like crime prevention and education; and on paying interest on the federal debt.

Taxes on corporate profits constitute about one-seventh of federal receipts. The remainder of federal revenue comes from excise taxes (on cigarettes, gasoline, etc.), tariffs on imports, and other fees from firms and individuals. Federal government revenue, 2012 Figure 16.4

Social Security and Medicare have helped to reduce poverty among the elderly, while Medicaid helps improve the health of poor people. • But the aging population and rising health care costs are combining to put those programs in jeopardy. • Through 2090, the budget shortfall for these programs is estimated to be enormous: almost $60 trillion

It is likely that a combination of these measures will eventually need to be adopted: • Increasing taxes • Decreasing benefits (including slower benefit growth, perhaps differently for different income groups) • Decreasing eligibility (SSI age already increasing from 65 to 67) But perhaps the most important element will be finding a way to reduce medical costs
