Branch of economics that studies aggregated indicators.

Macroeconomics is a branch of economics that studies the behavior and performance of an economy as a whole. It focuses on the aggregate changes in the economy such as unemployment, growth rate, gross domestic product (GDP), and inflation.

Definition of Macroeconomics

Macroeconomics is derived from the Greek prefix "makro-" meaning "large" and economics. As its name suggests, macroeconomics is a study of economics on a large scale. It analyzes entire industries and economies, rather than individual markets. Macroeconomics examines economy-wide phenomena such as changes in unemployment, national income, rate of growth, GDP, inflation, and price levels.

Difference between Macroeconomics and Microeconomics

While both fields are part of economics, they focus on different aspects. Microeconomics is the study of individuals and business decisions, while macroeconomics looks at the decisions of countries and governments.

Microeconomics focuses on supply and demand, and other forces that determine price levels for specific goods and services in an economy, while macroeconomics aims to understand the factors that influence positive and negative growth in the GDP, and other large-scale economic factors.

Key Concepts in Macroeconomics

Gross Domestic Product (GDP)

GDP is the total value of all goods and services produced by a country in a specific time period. It serves as a comprehensive measure of a nation’s overall economic activity.


Inflation is the rate at which the general level of prices for goods and services is rising, and subsequently, purchasing power is falling. Central banks attempt to limit inflation, and avoid deflation, in order to keep the economy running smoothly.


Unemployment refers to the number of people in an economy who are willing and able to work, but are not working. The unemployment rate is the number of unemployed people divided by the total number of people in the workforce.

Fiscal Policy

Fiscal policy refers to the use of government spending and tax policies to influence macroeconomic conditions, including aggregate demand, employment, inflation and economic growth.

Monetary Policy

Monetary policy is the policy adopted by the monetary authority of a country that controls either the interest rate payable on very short-term borrowing or the money supply, often targeting inflation or the interest rate to ensure price stability and general trust in the currency.

The Role of Macroeconomics in Society

Macroeconomics plays a vital role in society. It is used by governments to understand how to allocate resources, how to respond to crises, and how to build policies and plans. For individuals, understanding macroeconomics can help make informed decisions about spending and saving, investments, and job prospects.

In conclusion, macroeconomics provides a high-level view of an economy and the forces that move it. It helps us understand the workings of a complex modern economy, and provides the tools for policy-makers to improve it.
