Resources are limited
Since our resources are limited, more of one good can be produced only at the expense of producing fewer of other goods. If the cost of producing a given commodity rises the supply curve moves to the left and price rises. In this way the higher cost is signaled to consumers who can then decide to what extent they are prepared to pay these higher costs by foregoing other goods.
