Factors Determining Market / Extent of Market

• The “extent of the market” means how wide or limited an area is covered by the buying and selling of a particular product.
• Some products have a broad market (global/national); others are only local.

1] Nature of Demand

• If a product has permanent, widespread demand (e.g., gold, silver), its market is large.
• If demand is only in a local area (e.g., regional snacks), the market is small.

2] Means of Transportation and Communication

• Good roads, railways, shipping, and internet help a market reach more places.
• Poor transport limits the market to local areas.

3] Nature of the Commodity

• Durable and portable products (e.g., smartphones) can be sold in bigger markets.
• Perishable or fragile items (e.g., milk, vegetables) cannot be sent far, so have local markets.

4] Currency and Credit 

• A good, reliable money and credit system increases trust and helps markets grow.

5] State (Government) Policy

• High taxes or bans on certain goods limit market size.
• Free trade policies expand markets.

6] Division of Labour

• More division of labour means production can be specialized and cheaper, making bigger markets possible.

7] Durability

• Non-perishable (durable) goods can be sold far away.
• Perishable goods (fresh foods) have small, local markets.

8] Portability

• Easy-to-carry items (e.g., clothes, phones) have large markets.
• Heavy or expensive-to-transport items (e.g., bricks) have small markets.
  Example: Bricks are sold locally because they are heavy and expensive to move.

9] Sampling and Grading

• If customers can judge a sample or grade (like wool, electronics), sellers can send products nationally/globally.

10] Peace, Security, and Honesty

• Business prefers peaceful, honest places (large markets).
• Unrest, dishonesty, or bad law and order reduce market size.

11] Government Restrictions

• Restrictions and bans (import/export limits) shrink market; no restrictions expand it.

12] Number of Substitutes

• More substitutes = smaller market, as buyers easily switch products.

13] Modern Trade Methods

• Advertising, storage facilities, and online selling expand markets today.

14] Internal Country Conditions

• Political stability, a good economy, and strong infrastructure help markets grow.

A smartphone is produced in one city but sold all over the world because it is durable, portable, and online trade is easy. Fresh bread, on the other hand, is usually sold only in the local area because it goes bad quickly.

• Market size depends on product, transport, policy, and more.
• Durable, portable goods = big market.
• Perishable or hard-to-transport = small market.
• Government rules can expand or limit the market.
