Summary
The price mechanism is a system where market forces of demand and supply interact to determine prices, performing signalling, incentivizing, and rationing functions to allocate resources. It operates in various markets including local, national, and global markets.
- Rationing Function — allocates limited resources based on price. Example: High prices limit access to scarce resources to those who can afford them.
- Signalling Function — provides information to buyers and sellers about market conditions. Example: Rising prices signal increased demand or reduced supply.
- Incentive Function — motivates buyers and sellers to change their behavior based on price changes. Example: Low prices encourage consumers to buy more, while high prices encourage producers to supply more.
