Summary and Exam Tips for Supply
Supply is a subtopic of The allocation of resources, which falls under the subject Economics in the Cambridge IGCSE curriculum. Supply refers to the willingness and ability of producers to offer goods and services at a given price. Market supply is the total amount of a product that all producers are willing to supply, while quantity supplied is the specific amount producers are willing to offer at a particular price.
The Law of Supply states that there is a direct relationship between price and supply: as price increases, supply increases, and vice versa. This relationship is depicted through movements along the supply curve. An increase in price leads to an extension in supply, while a decrease results in a contraction in supply.
Shifts in the supply curve occur due to factors other than price changes. An increase in supply, without a price change, shifts the curve to the right, while a decrease shifts it to the left. Factors influencing these shifts include changes in resource availability, production costs, technological advancements, and external conditions like weather or natural disasters.
