DEFINITION: Economics is a science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.
MEANING: Ends are wants or desires that individual consumers, firms or businesses and government are constantly using their scarce resources to satisfy. They are in the form of goods and services, goals or circumstances that mankind desires.
CHARACTERISTICS OF ENDS/WANTS
1. They are unlimited.
2. They differ among individuals and over time.
3. As soon as they are satisfied, they tend to create other ends. This explains why they are unlimited.
4. They have value and command price.
5. They compete for the scarce resources.
MEANING: Means are the same as resources. They are the goods and services used to produce other goods and services to satisfy human wants.
Personal income and time are part of what are classified as means. Other terms used for means are factors of production, resources and inputs.
