📌 Introduction to Economics
Economics is a social science that studies how individuals, businesses,
governments, and societies make choices about allocating limited resources to
satisfy their unlimited wants.
In simple terms:
> "Economics is the study of scarcity and choice."
Since resources like money, land, labor, and raw materials are limited, but human
wants are unlimited, economics helps us understand how to manage these scarce
resources effectively.

📌 Meaning of Economics
The word Economics originates from the ancient Greek word Oikonomia, which means
household management.
Modern definitions:
According to Adam Smith (Father of Economics):
> "Economics is the study of the nature and causes of wealth of nations."
According to Alfred Marshall:
> "Economics is a study of mankind in the ordinary business of life. It examines
how people earn income and how they use it."
According to Lionel Robbins:
> "Economics is the science which studies human behavior as a relationship between
ends and scarce means which have alternative uses."
