Meaning of Economics

Economics is a social science that studies human behaviour in relation to scarce resources which have alternative uses for the satisfaction of human wants.

Economics is concerned with:

  • Human wants
  • Scarcity of resources
  • Choice
  • Allocation of resources

Definitions by Economists

According to Lionel Robbins:

“Economics is the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.”

According to Adam Smith:

“Economics is the study of wealth.”

BASIC CONCEPTS IN ECONOMICS

1. Human Wants

Human wants are the desires people wish to satisfy.

Characteristics of Human Wants

  • They are unlimited.
  • They vary from person to person.
  • Some wants are more important than others.
  • They recur regularly.

Examples

  • Food
  • Shelter
  • Clothing
  • Education
  • Transportation

2. Scarcity

Scarcity means that the resources available to satisfy human wants are limited.

Examples of scarce resources:

  • Money
  • Time
  • Land
  • Labour

3. Choice

Since resources are limited, individuals must select the most important wants and leave others unsatisfied.

Example: A student with ₦2,000 may choose between buying a textbook or a pair of sandals.

NATURE OF ECONOMICS

Economics is:

  1. A social science.
  2. Concerned with human behaviour.
  3. Concerned with allocation of scarce resources.
  4. Both theoretical and practical.
  5. Dynamic in nature.

SCOPE OF ECONOMICS

The scope of Economics refers to the areas Economics covers.

1. Microeconomics

Microeconomics studies the behaviour of individuals, households and firms.

Examples:

  • Demand and supply
  • Price determination
  • Consumer behaviour

2. Macroeconomics

Macroeconomics studies the economy as a whole.

Examples:

  • Inflation
  • Unemployment
  • National income
  • Economic growth

IMPORTANCE OF ECONOMICS

  1. Helps individuals make wise decisions.
  2. Assists governments in policy making.
  3. Helps businesses maximize profit.
  4. Helps in the management of scarce resources.
  5. Promotes economic development.

TEACHER’S ACTIVITIES

  1. Explains the meaning of Economics.
  2. Discusses scarcity and choice using practical examples.
  3. Differentiates between microeconomics and macroeconomics.
  4. Asks students questions based on everyday economic activities.

  1. Listen attentively.
  2. Participate in class discussion.
  3. Give examples of scarce resources.
  4. Differentiate between wants and needs.

    b. Scarcity
    c. Choice

  2. Mention five examples of human wants.

  3. State three differences between microeconomics and macroeconomics.

BOARD SUMMARY

  • Economics is the study of human behaviour in relation to scarce resources.
  • Human wants are unlimited.
  • Resources are scarce.
  • Choice arises because resources are limited.
  • Economics is divided into microeconomics and macroeconomics.

CONCLUSION

The teacher revises the lesson by asking oral questions and giving further explanations where necessary.
