Economics is the study of how
people, businesses, and governments use limited resources to satisfy unlimited
wants. अर्थशास्त्र वह विषय है जो बताता है कि व्यक्ति,
व्यवसाय और सरकार सीमित संसाधनों का उपयोग असीमित आवश्यकताओं और
इच्छाओं को पूरा करने के लिए कैसे करते हैं।
2. Needs and Wants (आवश्यकताएँ एवं
इच्छाएँ)
Needs
(आवश्यकताएँ)
- Necessary for survival.
- Essential items.
Examples
- Food (भोजन)
- Water (पानी)
- Shelter (आवास)
Wants
(इच्छाएँ)
- Improve comfort and lifestyle.
- Unlimited and keep changing.
Examples
- Mobile phone
- Car
- Vacation
Key Point
Needs are limited, but wants are
unlimited. आवश्यकताएँ सीमित होती हैं, लेकिन
इच्छाएँ असीमित होती हैं।
3. Resources and Scarcity (संसाधन एवं
दुर्लभता)
Resources
(संसाधन)
Resources are used to produce goods
and services.
Types
- Land (भूमि)
- Labour (श्रम)
- Capital (पूंजी)
- Technology (प्रौद्योगिकी)
Scarcity
(दुर्लभता)
Resources are limited while human
wants are unlimited.
Therefore, people must make choices.
Formula
Limited Resources + Unlimited Wants
= Choice (चुनाव)
4. Opportunity Cost (अवसर लागत)
Definition
The value of the next best
alternative that is sacrificed while making a choice.
किसी एक
विकल्प को चुनने पर छोड़े गए दूसरे सर्वोत्तम विकल्प का मूल्य अवसर लागत कहलाता
है।
Example
A farmer grows wheat instead of
barley.
➡
Opportunity cost = Barley production sacrificed.
5. Production Possibility Curve (PPC)
उत्पादन संभावना वक्र
Definition
Shows different combinations of
goods produced by using all available resources efficiently.
Features
- Shows trade-off
- Downward sloping curve
- Efficient use of resources
- Maximum possible production
Example
More Barley → Less Wheat
More Wheat → Less Barley
Remember
Every point on PPC represents efficient
production.

- Technology तकनीक
- Nature of product श्रम की उपलब्धता
- Labour availability सरकारी नियम
- Government laws उत्पाद
का प्रकार
