Quick questions on The price mechanism and resource allocation (QCE Economics Unit 1)

Because resources are scarce (the basic economic problem), every economy must decide what to produce, how to produce it, and for whom. In a market economy these decisions are made not by a central planner but by millions of decentralised buyers and sellers responding to prices. Adam Smith called this coordination the "invisible hand": self-interested decisions, guided by prices, produce a coordinated allocation of resources.

The real power of the price mechanism is dynamic: it reallocates resources automatically when conditions change.

Prices carry information. A rising price signals that buyers want more of a good than is currently available; a falling price signals the opposite. Producers and consumers do not need to know why demand or supply changed; the price change itself tells them to act.

Prices reward action. A higher price raises potential profit, giving producers an incentive to supply more and attracting resources into that market. A lower price gives consumers an incentive to buy more and producers an incentive to leave.

When a good is scarce relative to demand, a rising price rations it to those willing and able to pay. Higher prices choke off some quantity demanded and encourage some extra supply, eliminating the shortage. Price is the rationing device that clears the market without queues or rules.

Prices reward producers and consumers for responding to those signals (profit and purchasing decisions).
