When two lines on a diagram cross, this intersection usually means something. At any other price, the quantity demanded does not equal the quantity supplied, so the market is not in equilibrium at that price.

The demand curve is decreasing — lower prices are associated with higher quantities demanded, higher prices are associated with lower quantities demanded. The supply curve is increasing — lower prices are associated with lower supply, and higher prices are associated with higher quantities supplied. Suppose that the price is set at the equilibrium price, so that the quantity demanded equals the quantity supplied. Now think about the folks who are represented on the left of the equilibrium point.

Changes in equilibrium price and quantity when supply and demand change

When the supply and demand curves intersect, the market is in equilibrium. This is where the quantity demanded and quantity supplied are equal. The corresponding price is the equilibrium price or market-clearing price, the quantity is the equilibrium quantity. At this price level, market is in equilibrium. Market is clear. Surplus and shortage:.

If the market price is above the equilibrium price, quantity supplied is greater than quantity demanded, creating a surplus. Market price will fall. Example: if you are the producer, you have a lot of excess inventory that cannot sell.

Will you put them on sale? It is most likely yes. Therefore, surplus drives price down. If the market price is below the equilibrium price, quantity supplied is less than quantity demanded, creating a shortage. The market is not clear. It is in shortage. Market price will rise because of this shortage. Example: if you are the producer, your product is always out of stock.

Will you raise the price to make more profit? Most for-profit firms will say yes. Therefore, shortage drives price up. If a surplus exist, price must fall in order to entice additional quantity demanded and reduce quantity supplied until the surplus is eliminated. If a shortage exists, price must rise in order to entice additional supply and reduce quantity demanded until the shortage is eliminated.

Market is in surplus. Market is not clear. Market is in shortage. Government regulations will create surpluses and shortages in the market. When a price ceiling is set, there will be a shortage.

When there is a price floor, there will be a surplus. Equilibrium price and quantity are determined by the intersection of supply and demand. A change in supply, or demand, or both, will necessarily change the equilibrium price, quantity or both. It is highly unlikely that the change in supply and demand perfectly offset one another so that equilibrium remains the same.

Example: This example is based on the assumption of Ceteris Paribus. An increase in demand will create a shortage, which increases the equilibrium price and equilibrium quantity. An increase in supply will create a surplus, which lowers the equilibrium price and increase the equilibrium quantity. From the above analysis, we can tell that equilibrium quantity will be higher. Therefore, the change in equilibrium price cannot be determined unless more details are provided.

Detail information should include the exact quantity the exporter and importer is engaged in. By comparing the quantity between importer and exporter, we can determine who has more impact on the market. In the following table, an example of demand and supply increase is illustrated.

The new curve intersects the original supply curve at a new point. At this point, the equilibrium price market price is higher, and equilibrium quantity is higher also. In this graph, demand is constant, and supply increases. The new curve intersects the original demand curve at a new point. At this point, the equilibrium price market price is lower, and the equilibrium quantity is higher.

In this graph, the increased demand curve and increased supply were drawn together. The new intersection point is located on the right hand side of the original intersection point.

This new equilibrium point indicated an equilibrium quantity which is higher than the original equilibrium quantity. The equilibrium price is also higher. It is because demand has increased relatively more than supply in this case. This supply and demand factor exercises may help you better apply these concepts.

Price Floor: is legally imposed minimum price on the market. Transactions below this price is prohibited. Price Ceiling: is legally imposed maximum price on the market. Transactions above this price is prohibited.

Putting the supply and demand curves from the previous sections together. In this graph, supply is constant, demand increases.

As the new demand curve Demand 2 has shown, the new curve is located on the right hand side of the original demand curve.

Changes in equilibrium price and quantity when supply and demand change

When the supply and demand curves intersect, the market is in equilibrium. This is where the quantity demanded and quantity supplied are equal. The corresponding price is the equilibrium price or market-clearing price, the quantity is the equilibrium quantity. At this price level, market is in equilibrium. Market is clear.


Market Equilibrium. Quantity Demanded = Quantity Supplied. Finding the equilibrium price and quantity levels.. In general,. Demand Function: QD = a + bP.


Supply and demand

The equilibrium of supply and demand in each market determines the price and quantity of that item. The model is so The following are the determinants of the supply: 1. Effectively, there is an increase in both the equilibrium price and quantity.
