Economic theories shape U.S. fiscal policy, influencing how the government manages the economy. Keynesian, supply-side, and monetarist approaches offer different strategies for growth and stability, guiding decisions on taxes, spending, and monetary policy.
Congress wields significant economic influence through fiscal policy tools like taxation and spending. The federal budget process, involving the president and Congress, determines funding priorities and impacts domestic policies, while economic indicators guide policy goals.
Economic Theories and Fiscal Policy
Economic theories in U.S. policy
Three major economic theories have shaped how the U.S. government approaches fiscal policy. Each one offers a different answer to the question: What should the government do to keep the economy healthy?
- Keynesian economics advocates government intervention to stabilize the economy during recessions. The idea is that when people and businesses aren't spending enough, the government should step in with increased spending and lower taxes to boost demand. The New Deal programs of the 1930s are a classic example.
- Supply-side economics focuses on the production side of the economy. It argues that cutting taxes and reducing regulation will incentivize businesses to invest and produce more, which then benefits everyone. The Reagan-era tax cuts of the 1980s ("Reaganomics") are the most well-known application.
- Monetarism emphasizes controlling the money supply as the key to economic stability. Rather than big swings in government spending, monetarists argue for steady, predictable growth in the money supply to keep inflation in check. Federal Reserve policies reflect this thinking.
Federal Budget and Domestic Policy
Congressional economic influence
Congress shapes the economy through fiscal policy, which has two main levers: taxation and government spending.
- Taxation
- Increasing taxes reduces disposable income and can slow economic growth.
- Decreasing taxes can stimulate spending and investment. The Bush tax cuts of 2001 and 2003 are a recent example.
- Tax brackets determine the rate at which income is taxed at different levels. Higher income gets taxed at a higher rate in a progressive system.
- Government spending
- Increasing spending can boost aggregate demand and create jobs (think infrastructure projects like highways and bridges).
- Decreasing spending can reduce budget deficits and help curb inflation.
Beyond deliberate policy choices, the government also has automatic stabilizers that kick in without Congress needing to pass new legislation. These adjust on their own based on economic conditions:
- Progressive income tax: When the economy slows and people earn less, they fall into lower tax brackets and automatically pay less in taxes, leaving more money in their pockets.
- Unemployment benefits: Provide temporary income for workers who lose their jobs, which rises automatically during recessions as more people file claims.
- Welfare programs: Programs like food stamps (SNAP) and Medicaid expand as more people qualify during economic downturns, cushioning the blow.
Federal budget and domestic policy
The federal budget process is how the government decides where money goes each year. It involves both the president and Congress:
- Executive budget proposal — The president submits a budget request to Congress outlining spending priorities and revenue projections. This is essentially a wish list; Congress is not bound by it.
- Congressional budget resolution — Congress sets overall spending and revenue targets, allocating money among broad categories like defense, education, and healthcare.
- Appropriations bills — These provide specific funding for agencies and programs. They must be passed by both chambers of Congress and signed by the president to take effect.
Budget deficits and surpluses are central to fiscal policy debates:
- A deficit occurs when spending exceeds revenues, leading to increased government borrowing and a higher national debt.
- A surplus occurs when revenues exceed spending, which can be used to pay down debt or fund new programs.
- A balanced budget occurs when revenues equal expenditures. This is rare at the federal level.
Budget decisions directly shape domestic policy. Funding levels for Social Security, Medicare, education, and infrastructure all depend on what Congress appropriates. Because resources are limited, trade-offs between competing priorities drive much of the political debate in Washington.
Economic Indicators and Policy Goals
Policymakers rely on a few key indicators to gauge the economy's health and guide their decisions:
- Gross Domestic Product (GDP) measures the total value of all goods and services produced within the country over a set period. It's the broadest measure of economic activity.
- Economic growth refers to the increase in production of goods and services over time, usually tracked as the percentage change in GDP.
- Inflation is the rate at which the general level of prices for goods and services rises, which erodes purchasing power. The Federal Reserve targets about 2% annual inflation as a healthy rate.
These indicators influence both budget and tax policy decisions as the government tries to maintain stability and promote growth.
Monetary Policy and Economic Regulation
Federal Reserve's economic role
While Congress controls fiscal policy, the Federal Reserve (the Fed) controls monetary policy, which involves managing the money supply and interest rates. The Fed operates independently from Congress and the president.
The Fed has three main tools:
- Setting the federal funds rate — This is the interest rate banks charge each other for overnight loans. It influences short-term interest rates across the economy. Lower rates encourage borrowing and spending; higher rates cool things down.
- Open market operations — The Fed buys or sells government securities (like Treasury bonds) to control the money supply. Buying securities puts more money into circulation; selling them pulls money out.
- Reserve requirements — This determines how much money banks must hold in reserve rather than lend out. Higher requirements reduce lending; lower requirements increase it.
Beyond monetary policy, the Fed also regulates the financial system. It supervises banks through tools like stress tests and capital requirements to prevent failures. It also enforces consumer protection laws like the Truth in Lending Act and the Fair Credit Reporting Act.
The Fed operates under a dual mandate from Congress: promote maximum employment and maintain price stability. These two goals can sometimes conflict. For example, raising interest rates to fight inflation may slow job growth, so the Fed constantly balances these trade-offs depending on current economic conditions.
