Learn It 2.4.5: Macroeconomics

Fiscal Policy

The other economic tool used by the government is fiscal policy, its program of taxation and spending. By cutting taxes or by increasing spending, the government can stimulate the economy. The more government buys from businesses, the greater the business revenues and output. Likewise, if consumers or businesses have to pay less in taxes, they will have more income to spend for goods and services. Tax policies in the United States therefore affect business decisions. High corporate taxes can make it harder for U.S. firms to compete with companies in countries with lower taxes. As a result, companies may choose to locate facilities overseas to reduce their tax burden.

Why Taxes Matter

Nobody likes to pay taxes, but without tax revenue, there would be no way for the government to pay for things like repairing roads and running public schools. Although most U.S. citizens complain that they are overtaxed, we pay lower taxes per capita (per person) than citizens in many countries similar to ours. In addition, our taxes represent a lower percentage of gross income and GDP compared to most countries.

The Impact of Government Spending

While fiscal policy has a major impact on business and consumers, continual increases in government spending raises another important issue. When government takes more money from business and consumers (the private sector), a phenomenon known as crowding out occurs. Here are three examples of crowding out:

  1. The government spends more on public libraries, and individuals buy fewer books at bookstores.
  2. The government spends more on public education, and individuals spend less on private education.
  3. The government spends more on public transportation, and individuals spend less on private transportation.

Budget Deficits and the National Debt

If the government spends more for programs (social services, education, defense) than it collects in taxes, the result is a federal budget deficit. To balance the budget, the government can cut its spending, increase taxes, or do some combination of the two. When it cannot balance the budget, the government must make up any shortfalls by borrowing (just like any business or household).

From Surplus to Soaring Deficit

In 1998, for the first time in a generation, there was a federal budget surplus (revenue exceeding spending) of about $71 billion. That budget surplus was short lived, however. In 2022, the federal deficit was $1.38 trillion.[1] The U.S. government has run budget deficits for many years. The accumulated total of these past deficits is the national debt, which now amounts to about $31.5 trillion.[2] To pay for the deficit, the U.S. government borrows money from people and businesses in the form of Treasury bills, Treasury notes, and Treasury bonds. These are securities that represent the promise of the federal government to pay interest to their owners.
