9.3, supply curve SS slope upwards from left to right, indicating direct relationship between price and quantity supplied. When the price of a specific commodity increases, potential producers are encouraged to enter the market and produce the good to make money. The market supply rises as the number of businesses increases. However, once the price begins to decline, some businesses that do not anticipate making any money at a low price may stop production or cut it back. As the number of businesses in the market declines, it decreases the supply of the given commodity.

As a result of their observations, they have arrived at the law of supply. Law of supply states the direct relationship between price and quantity supplied, keeping other factors constant (ceteris paribus). The law of supply and demand outlines the interaction between a buyer and a seller of a resource.

However, at a relatively lower price, the producers do not release big quantities from their stocks. They start increasing their inventories with a view that price may rise in near future. The law of supply is one of the most fundamental concepts in economics.

• Sometimes sellers create shortage in the market to create demand at higher prices and this is possible only when the seller community is involved in creating shortage.
• 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.
• It is also assumed that there is no change in climatic situation.
• These limitations are crucial for a more nuanced perspective on supply behavior in the real world.
• Or, supply and demand may be balanced, which means the market has reached equilibrium.
• The cost of production increases due to increase in quantity supplied.

No change in tax policy

• This occurs when the supply curve becomes less steep as the price increases, meaning that the percentage change in supply increases at a faster rate than the percentage change in price.
• The market supply data of the commodity x as shown in the supply schedule is now presented graphically.
• These assumptions of law of supply act as the invisible threads that hold the framework together, ensuring the price-supply relationship remains intact.

If sellers expect a fall in price in the future, then the law of supply may not hold true. In this situation, the sellers will be willing to sell more even at a lower price. However, if they expect the price to rise in the future, they would reduce the supply of the commodity, in order to supply the commodity later at a high price. When the price of a good increases, the sellers are ready to supply more goods from their stocks.

What is the law of supply? Meaning, assumptions, and why does the supply curve slope upward?

It helps explain the upward-sloping supply curve commonly seen in supply and demand diagrams and is a foundational concept in economics. The law of supply states that a price increase will increase production. It has implications for suppliers, specifically those who offer something of low value or availability. It also has implications for large-scale production operations, as the rising cost of resources such as raw materials and labor could harm their ability to generate a profit.

So, at point A, the quantity supplied will be Q1 and the price will be P1, and so on. The Law of Supply is a cornerstone of economic analysis, providing valuable insights into how producers respond to changes in prices and market conditions. The law of supply operates under the bold presumption that production can scale infinitely in response to rising prices.

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. The law of supply is not valid if sellers expect a fall in the price in the future. The sellers will be willing to sell more in this situation, even at a cheaper price. However, if sellers expect an increase in the future price, they will reduce supply to deliver the item later at a higher price. Price is a dominant factor in the determination of the supply of a commodity.

Business Economics Tutorial

The above table indicates that when the price of the commodity rises, an increasing number of units are offered for sale. 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.

They strip away complexities, offering a clear lens through which to view the price-supply relationship. Yet, the real world rarely abides by such neat constraints. Deviations, inconsistencies, and external influences often challenge these assumptions, reminding us of the law’s theoretical nature. Understanding these assumptions of law of supply, however, equips us to navigate the intricate realities of supply-side economics with greater clarity. In a assumptions of law of supply nutshell, we can say that assumptions of law of supply are very important to get a basic understanding of this law relating to supply. The law of supply summarizes the effect that price changes have on producer behavior.

The supply curve is a horizontal line, indicating that suppliers are highly responsive to price changes. 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. We know, price is the dominant factor in determining supply of a commodity. As price of the commodity increases, there is more supply of that commodity in the market and vice-versa. This behaviour of producers is studied under the law of supply.

Similarly, if the number of firms decreases, the supply of commodity will also decrease. According to the law of supply, if the price of a product rises, the supply of the product also rises and vice versa. Similarly, if the price of the product decreases, the supplier would decrease the supply of the product in the market as he/ she would wait for a rise in the price of the product in the future. The law of supply can be explained through a supply schedule and a supply curve.

It’s time to see the Law of Supply Graph, Table, its underlying principles, determinants, assumptions, limitations and examples. Government interventions—like subsidies or taxes—are conspicuously absent. Due to the scarcity of resources, output and supply cannot be enhanced in economically underdeveloped countries. The supply function is now explained with the help of a schedule and a curve. As we assumed the different values of ‘P’ from zero to 5, then the calculated values of Qs increases from – 2 to 8. Law is one sided as it explains only the effect of change in price on the supply, and not the effect of change in supply on the price.

The law of supply assumes in one of the different assumptions of law of supply, that their costs remain steady, creating a stable foundation for decision-making. 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. Thus, the above schedule shows that there is positive relationship in between price and quantity supplied of a commodity. Production costs like raw materials, labor costs, overhead costs and selling and administration may increase along with the increase in price.

The supply curve has a constant slope and represents a situation where the responsiveness of supply is proportionate to price changes. 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. If the firm aims to earn more profit, then the firm creates a shortage to sell at a higher price.

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). In the table above, the produce are able and willing to offer for sale 100 units of a commodity at price of $4. As the price falls, the quantity offered for sale decreases. At price of $1, the quantity offered for sale is only 40 units. The cost of production increases due to increase in quantity supplied.
