Products, goods and services
1) Meaning of products
- When people do physical or mental work to satisfy other people’s wants through exchange, the result they provide (goods or services) is called a product or output.
- So, products include both goods and services.
2) Goods
- Goods are tangible (physical) items; they can be seen and touched.
- In economics, goods are tangible items that give satisfaction when they are used or consumed.
Examples:
- Food items: rice, wheat, meat, eggs, fish
- Clothing: shirts, trousers
- Other goods: furniture, house, car, bicycle
3) Services
- Services are intangible; they cannot be seen or touched.
- They are activities performed to satisfy human wants.
Examples:
- Services of doctors, teachers, lawyers, engineers
- Banking, insurance, transport, tourism, medical treatment
Classification of products
Products can be classified on four bases:
1) Based on productive activities
- Primary products
- Secondary products
- Tertiary products
2) Based on process of production
- Intermediate products
- Final products
3) Based on durability
- Non-durable products
- Durable products
4) Based on use
- Consumer products
- Investment (producer/capital) products
Classification based on productive activities
Economic activities are grouped into primary, secondary and tertiary activities. The products from these activities are called primary, secondary and tertiary products.
1) Primary products
- Produced by primary activities that use natural resources.
- These are basic goods directly obtained from nature.
Examples:
- Food grains: wheat, rice
- Dairy products: milk, curd, butter
- Other: fruits, vegetables, fish, wood
2) Secondary products
- Produced by secondary (industrial/manufacturing) activities.
- Natural primary products are used as raw materials to make manufactured goods.
Examples:
- Finished steel made from iron ore
- Fabrics and clothes made from cotton
- Packaged foods made from crops
3) Tertiary products
- Produced by tertiary (service) activities.
- These are service products that support primary and secondary sectors and also serve consumers.
Examples:
- Banking and insurance services
- Tourism and transport services
- Medical and educational services
Classification based on process of production
Here, products are divided into intermediate products and final products.
1) Intermediate products
- Goods produced to be used in making other goods.
- They are not meant for direct use by the final consumer.
Examples:
- Car parts (tyres, seats, glass) bought from other industries during car production
- Flour used by a bakery to make bread
2) Final products
- Goods that are ready for final use.
- Purchased by final consumers for consumption or by firms for investment.
Examples:
- A complete car sold to a customer
- A TV bought for home use
- A finished house ready for living
Classification based on durability
Here, goods are divided into non-durable and durable products.
1) Non-durable products
- Goods that are used up in a short time, often quickly and sometimes perishable.
- They give satisfaction only once or a few times.
Examples:
- Milk, bread, fruits, vegetables
- Soap, shampoo, cooking oil
2) Durable products
- Goods that last for a long period and give services many times.
- They are not fully used up in one or two uses.
Examples:
- Cars, refrigerators, TV sets
- Furniture, washing machines, computers
Classification based on use of products
Here, products are divided into consumer products and investment (producer/capital) products.
1) Consumer products (consumer goods)
- Goods that are directly consumed to satisfy human wants.
- Mainly purchased by households.
Examples:
- Food items: bread, rice, biscuits
- Clothing: shirts, trousers, shoes
- Daily-use goods: toothpaste, soap
2) Investment products (producer or capital goods)
- Goods used to produce other goods and services, not for direct consumption.
- Used mainly by firms and producers.
Examples:
- Machines and tools in a factory
- Equipment and plant
- Raw materials like steel, wood, cement used in production
Important note (same good, different use):
- A car used by a family for personal travel → consumer durable.
- A car used by a taxi company to earn income → investment (capital) good.
Real-Life Applications
1) School:
- Textbooks, notebooks → goods (consumer products).
- Teaching by teachers → service (tertiary product).
2) Home:
- Food items your family buys daily → non-durable consumer goods.
- Fridge, TV, washing machine → durable consumer goods.
3) Business:
- Factory machines, tools → investment products.
- Steel, wood used to make furniture or buildings → intermediate products / capital goods.
Key Points: Products
- Products include both goods and services, and both satisfy human wants.
- Goods are tangible, services are intangible.
- On the basis of productive activities, products are primary, secondary, or tertiary.
- On the basis of process of production, products are intermediate (inputs) or final (ready for use).
- On the basis of durability, goods are non-durable (short life) or durable (long life).
- On the basis of use, products are consumer goods (for direct consumption) or investment/capital goods (for further production).
- The same good can be consumer or investment good, depending on how it is used.
