2.11 - Relationships Between Different Markets
Alternative demand and substitute goods
Alternative demand involves products that can replace each other in meeting consumer needs. These are known as substitute goods, where changes in the price of one affect the demand for the other.
Substitute goods
- Substitute goods are alternatives that consumers can choose between.
- If the price of one substitute rises, demand for it decreases as consumers switch to the cheaper option, leading to higher demand and possibly a price increase for the alternative.
- This shift occurs because buyers seek better value, making substitutes directly competitive in the market.
Joint demand and complementary goods
Joint demand refers to products that are used together, where the demand for one influences the other. These are called complementary goods, and their relationship affects pricing and supply decisions.
Complementary goods
- Complementary goods are items consumed alongside each other.
- The link exists because these goods enhance each other's value, encouraging combined purchases.
- An increase in the supply of one complementary good lowers its price, which boosts demand for the paired product as consumers are more likely to buy both.
Derived demand in production
Derived demand occurs when the need for a resource or input stems from the demand for the final product it helps create. This concept is key in understanding supply chains and production processes.
How derived demand works
- A rise in demand for the end product increases the demand for the inputs involved in its production.
- The need for these inputs is not direct but comes from the overall market for the finished goods or services.
Joint supply of products
Joint supply happens when multiple products are generated from the same production process, even if they serve different purposes. This creates interconnected supply dynamics between the items.
How joint supply works
- Joint supply involves goods produced simultaneously from one source.
- This relationship arises because the manufacturing or extraction process naturally yields both items, linking their availability in the market.
- If demand for one jointly supplied product grows, producers increase output, which raises the supply of the related product and can cause its price to drop.
