As a general rule, supply curve slopes upwards, showing that quantity supplied rises with a rise in price. However, in certain cases, positive relationship between supply and price may not hold true. If the seller expects that the price of commodity is going to fall in near future, he will try to sell more even if the price level is very low. On the other hand, if the seller expects further rise in price of the commodity he will not sell more even if the price level is high. In the given figure, price and quantity supplied are measured along the Y-axis and the X-axis respectively.

However, there are some exceptions to the law of supply, which one should understand. If the global price of oil increases, oil companies will be motivated to extract and supply more oil to the market. This is because higher prices make oil extraction more profitable, leading to more investment in exploration, drilling, and production, which increases the overall supply of oil. In unitary elastic supply, the percentage change in the quantity supplied is exactly equal to the percentage change in price.
The Assumption, Reasons and Exceptions to Law of Supply Economics
They work on building up their inventory in anticipation of potential price increases in the future. Economists have studied the behaviour of both buyers and sellers. They have discovered the law of supply as a result of their findings. The law of supply describes the relationship between price and amount supplied when all other variables remain constant (ceteris paribus).
It works with the law of demand to explain how market economies allocate resources and determine the prices of goods and services. Conversely, if the prices of the various factors of production fall, then in lowering the cost of production, an increase in the supply occurs. If the quantity of natural resources (minerals, gas, coal, oil, etc.) increases, the cost of production decreases. “Other things remaining the same, if the price of a commodity increases its quantity supplied increases and if the price of a commodity decreases, quantity supplied also decreases”.
In the above graph, the rising slope of the supply curve (SS) indicates assumptions of law of supply a clear relationship between price and quantity supplied. The above table indicates that when the price of the commodity rises, an increasing number of units are offered for sale. It shows that there is a straight connection between the supply of goods and the price of a commodity while other factors remain stable.
When a seller wants to clear its old stock in order to store new goods, he may sell large quantity of goods at heavily discounted price. If ten people want to buy a pen, and there’s only one pen, the sale will be based on the level of demand for the pen. The supply function requires more pens, which generates more production to meet demand. In plain terms, this law means that as the price of an item goes up, suppliers will attempt to maximize their profits by increasing the number of that item that they sell.
- It would then be possible to increase the supply of agricultural products.
- In this case, the quantity supplied is less responsive to price changes.
- If better methods of production are invented, profit increases at the previous price.
- If production is hampered due to natural calamities, then supply doesn’t increase despite a price increase.
- There are some rare things the supply of which is limited and inelastic.
- Rare, artistic and precious articles are also outside the scope of law of supply.
So, at point A, the quantity supplied will be Q1 and the price will be P1, and so on. It states that, all other factors being equal, as the price of a good or service increases, the quantity of that good or service that suppliers offer will increase, and vice versa. When the supply of the commodity rises or falls due to non-price determinants, the supply is said to have increased or decreased. So, supplier’s profits are dependent on consumers’ demands and values.

She is a financial therapist and transformational coach, with a special interest in helping women learn how to invest. There exists no speculation regarding the changes in price. All these assumptions come under the phrase “other things remaining the same“. The supply curve shifts to the right of the original supply curve.

These goods are being sold at very low prices for clearing their stock. When the supply of a good is elastic, the quantity supplied responds significantly to changes in price. A small increase in price leads to a proportionally larger increase in the quantity supplied. This type of supply curve is relatively flat, reflecting a high degree of responsiveness. The law assumes that external factors, such as government intervention, price controls, or supply restrictions, do not affect the producer’s ability to supply goods.
Criteria for Good Demand Forecasting
« The law of supply states that there is a positive relationship between quantity supplied and price, ceteris paribus. » It is assumed that technological advancements or changes in production capacity do not immediately affect supply. This means that producers are able to adjust the quantity supplied to match price changes without encountering technological limitations or bottlenecks in production capacity. In the real world, however, changes in technology or capacity can influence supply dynamics. Government may enforce the firms and producers to offer production at prevailing market price. In such a situation producer may not be able to wait for the rise in price.
- However, as the price starts falling, some firms which do not expect to earn any profits at a low price either stop the production or reduce it.
- Further rise in price to Rs.40 and then to Rs.50 per kg results in increase in quantity supplied by the seller to 4kg and then to 5kg.
- For example, a business will make more video game systems if the price of those systems increases.
- When the price of a good increases, the sellers are ready to supply more goods from their stocks.
- If goods are inelastic, then a change in price leads to relatively no response in the quantity supplied.
Each of the points shows the combination of price and quantity supplied. When the price .«of goods rises, other things remain the same, the quantity that is offered for sale increases, and as the price falls, the amount available for sale decreases. The law of supply does not apply to agricultural goods as their production depends on climatic conditions. If, due to unforeseen changes in weather, the production of agricultural products is low, then their supply cannot be increased even at higher prices. Thus, the production of agricultural products cannot be increased beyond a limit. Therefore, even a rise in price cannot increase the supply of these products beyond a limit.
The higher price provides an incentive for farmers to allocate more resources to wheat production, thereby increasing the quantity supplied. In this case, the quantity supplied is less responsive to price changes. A price increase results in a smaller proportional increase in the quantity supplied. The supply curve is steeper, showing that producers cannot easily adjust their supply to price changes. Production costs like raw materials, labor costs, overhead costs and selling and administration may increase along with the increase in price. Such situations may not allow producer to offer his products at a particular increased price.
It shows that the supply of labour refers to an exception of the law of supply. The market supply data of the commodity x as shown in the supply schedule is now presented graphically. It is important to note that we are talking about a theoretical idea. In the real world, many other factors also play a huge role in determining demand-supply. For example, when a government levies taxes on certain factors of production, the per-unit cost goes up.
