What is macroeconomics?

Macroeconomics is the study of the overall economy. This branch of economics includes all players in the economy -- the markets, businesses, consumers, and governments. It also considers all aspects of the economy, including inflation, gross domestic product (GDP), and unemployment.

Macroeconomics is a top-down look at the economy. It analyzes the impact that governments and countries can have on the economy. Macroeconomics differs from microeconomics, which is a more bottom-up view focused on the decisions of individuals and businesses.

A macroeconomics example

The Federal Reserve is a diligent student of macroeconomics. The Fed scrutinizes macroeconomic data because its dual mandate is to promote maximum employment while ensuring stable prices and moderate long-term interest rates. It can measure these criteria only on a macroeconomic level.

Macroeconomic information drives the Federal Reserve's policy moves. For example, if prices become unstable due to surging inflation data, the Fed will often adjust its interest rate policy by increasing the federal funds rate. That increases borrowing costs, which tends to lower GDP, helping reduce prices. On the other hand, if prices are stable, yet the unemployment rate is rising, the Fed will often reduce the federal funds rate. That lowers borrowing costs, giving companies and businesses more money to spend. That eventually increases GDP, which generally helps reduce the unemployment rate.
