Introduction to Macroeconomics: The Big Picture of Economic Science

Macroeconomics is an intriguing and broad field of study in economics. It’s where we zoom out to examine the larger, global economic framework instead of focusing on individual units within an economy. This branch of economics investigates the behavior of aggregate indicators like GDP, unemployment rates, and price indices.

The Scope of Macroeconomics

Macroeconomics studies the structure, behavior, decision-making, and performance of an economy as a whole. This includes regional, national, and global economies. Several key concepts and elements play critical roles in the understanding of macroeconomics.

Gross Domestic Product (GDP)

Gross Domestic Product is a comprehensive scorecard of the economic health of a country. It is the monetary value of all finished goods and services made within a country during a specific period. GDP provides an economic snapshot of a country, useful in comparing the economic health and growth of countries.

Inflation and Deflation

These two terms refer to the rate at which the general level of prices for goods and services is rising or falling, and subsequently, purchasing power is falling or rising. Central banks attempt to limit inflation — and avoid deflation — to keep the economy running smoothly.


Unemployment refers to the state of being without a job, while actively looking for one. The unemployment rate is a measure of the prevalence of unemployment and it’s calculated as a percentage by dividing the number of unemployed individuals by all individuals currently in the labor force.

Macroeconomic Models and Theories

The Keynesian School and the Monetarist School have produced some of the most influential theories in macroeconomics.

The Keynesian School

The Keynesian School, founded by John Maynard Keynes, argues that government intervention can stabilize the economy. According to Keynesian economics, state intervention is necessary to moderate the “boom and bust” cycles of economic activity.

The Monetarist School

The Monetarist School, led by Milton Friedman, argues that changes in the money supply are the most significant determinants of the rate of economic growth and the behavior of the business cycle. This school opposes the Keynesian view and believes that the government should not intervene in the economy.

The Relationship Between Macro and Microeconomics

While macroeconomics focuses on economies at the aggregate level, microeconomics delves into the individual units that make up the economy. These two branches of economics are interrelated and influence each other. Understanding both can provide a well-rounded picture of economic behavior and trends.

To use a metaphor from the world of trading, consider an economy as a stock market and each individual sector within the economy as a different stock. Macroeconomics would be similar to technical analysis, looking at the whole market to understand trends and patterns. In contrast, microeconomics would be like fundamental analysis, investigating each individual stock or company.

The Bottom Line

Macroeconomics plays a vital role in understanding the overall health of an economy and guiding policy decisions. It provides the big picture that’s essential for both policymakers and investors, allowing them to make informed decisions. By understanding macroeconomics, we can better comprehend the complex world of economics and how it affects our daily lives.

In the subsequent articles of this series, we will delve deeper into the various facets of macroeconomics, exploring topics like fiscal and monetary policy, international trade, and economic growth models. Understanding these aspects will further equip you with the tools necessary to evaluate the macroeconomic environment and its impacts on various sectors.
