How does fiscal policy stimulate or restrain the economy?

"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. Look again at Exhibit 1.6 . 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. Nobody likes to pay taxes, although we grudgingly accept that we have to. 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. Taxes are, of course, the major source of revenue for our government. Every year, the president prepares a budget for the coming year based upon estimated revenues and expenditures. Congress receives the president’s report and recommendations and then, typically, debates and analyzes the proposed budget for several months. The president’s original proposal is always modified in numerous ways."
