The price mechanism . It refers to how prices are determined in a market economy through the interaction of supply and demand. It helps allocate resources without direct government intervention.

How the Price Mechanism Works:

Determination of Prices:

• When demand increases, prices rise.

• When demand decreases, prices fall.

• When supply increases, prices fall.

• When supply decreases, prices rise.

Market Equilibrium:

• The equilibrium price is set where quantity demanded = quantity supplied.

Signaling Function:

• Prices signal producers and consumers about scarcity or surplus.

• High prices indicate strong demand or limited supply.

• Low prices indicate weak demand or excess supply.

Incentive Function:

• High prices encourage producers to supply more.

• Low prices encourage consumers to buy more.

Rationing Function:

• When goods are scarce, higher prices ration demand to those willing to pay more.

Advantages of the Price Mechanism:

✔ Efficient Resource Allocation – Directs resources to the most profitable uses.

✔ Consumer Choice – Buyers can decide based on price and preference.

✔ Competition & Innovation – Firms improve products and reduce costs.

✔ Flexibility – Adjusts to market changes automatically.

Disadvantages of the Price Mechanism:

❌ Market Failure – May not provide public goods (e.g., street lighting).

❌ Income Inequality – Can lead to wealth gaps.

❌ Negative Externalities – Prices may not reflect social costs (e.g., pollution).

❌ Unstable Prices – Sudden price changes can disrupt markets.

Government Intervention in the Price Mechanism:

• Price Ceilings (Maximum Prices): Prevents prices from rising too high (e.g., rent controls).

• Price Floors (Minimum Prices): Prevents prices from falling too low (e.g., minimum wages).

• Taxes and Subsidies: Adjusts prices to correct market failures.
