The fundamental economic model explaining how prices and quantities of goods and services are determined in a market based on their availability and individuals' purchasing desires.
Supply and Demand is a foundational economic model that describes how the prices and quantities of goods and services are established in a free market. This model suggests that the price level is determined by the intersection of the supply curve (availability of goods) and the demand curve (consumer willingness to purchase).
Supply represents how much of a good or service the market can offer. The quantity supplied refers to the amount of a certain good producers are willing to and able to sell at various prices, all else being equal.
The law of supply states that, all else being equal, an increase in the price of a good will increase the quantity supplied:
Demand signifies how much of a good or service consumers are ready to purchase at various price points. The quantity demanded is the specific amount of a good or service that buyers are willing to buy at a given price.
The law of demand states that, all else being equal, an increase in the price of a good will decrease the quantity demanded:
The equilibrium price is where the quantity of a good supplied matches the quantity demanded. This point is also known as the market-clearing price:
Changes in the factors affecting supply or demand can shift these curves, impacting the equilibrium price and quantity.
Elasticity measures how much the quantity supplied or demanded responds to price changes.
When the quantity supplied or demanded is relatively unresponsive to price changes, it is described as inelastic.
Supply and Demand principles are applicable in various fields such as finance, marketing, business strategy, and public policy. Understanding these concepts is crucial for making informed business decisions and understanding market dynamics.
