Economics is the study of how individuals, firms, governments and other organizations allocate scarce resources among competing wants and needs. This allocation process involves making choices and trade-offs between alternative uses of resources. The scarcity of resources means that people cannot have everything they want, so they must choose what they believe is most important.

Microeconomics and Macroeconomics

Economics is divided into two main branches: microeconomics and macroeconomics. Microeconomics is the study of individual economic agents, such as households, firms, and markets. It examines how these agents make decisions and interact with each other in markets, and how they respond to changes in prices, incomes, and other variables. Macroeconomics, on the other hand, is the study of the economy as a whole. It focuses on issues such as economic growth, inflation, unemployment, and international trade.

Economic Models

Economists use models to analyze economic behavior and predict how people will respond to changes in economic conditions. These models simplify the real world by making assumptions about the behavior of economic agents and the workings of markets. They can be used to test hypotheses, make predictions, and inform policy decisions.

Economics as a Social Science

Economics is a social science, which means that it is concerned with understanding human behavior. As such, it is not a hard science like physics or chemistry. Economic models are not as precise or accurate as physical models, and they are subject to a wide range of possible interpretations. Nonetheless, economics is a powerful tool for understanding how societies organize themselves and how they can improve their well-being.
