What is economics?

Understanding the discipline


  • Why are some countries rich and some countries poor? 

  • Why do women earn less than men?

  • How can data help us understand the world?

  • Why do we ignore information that could help us make better decisions?

  • What causes recessions?

 Economics can help us answer these questions. Below, we’ve provided links to short articles that illustrate what economics is and how it connects to our everyday lives.

Economics can be defined in a few different ways. It’s the study of scarcity, the study of how people use resources and respond to incentives, or the study of decision-making. It often involves topics like wealth and finance, but it’s not all about money. Economics is a broad discipline that helps us understand historical trends, interpret today’s headlines, and make predictions about the coming years.

Economics ranges from the very small to the very large. The study of individual decisions is called microeconomics. The study of the economy as a whole is called macroeconomics. A microeconomist might focus on families’ medical debt, whereas a macroeconomist might focus on sovereign debt.


What do economists do?

Economists have all kinds of jobs, such as professors, government advisors, consultants, and private sector employees. Using theoretical models or empirical data, they evaluate programs, study human behavior, and explain social phenomena. And, their contributions inform everything from public policy to household decisions.

Economics intersects many disciplines. Its applications include health, gender, the environment, education, and immigration. You can check out the field’s classification system (called JEL codes) for more topics that economists study.
