Text
Transactions require both buyers and sellers. Unlike demand that describes the behavior of consumers supply refers to the behavior of sellers. Thus, demand is only one aspect of decisions about prices and the amounts of goods traded, the other is supply. So, supply is one of the two key determinants of price. The theory of supply explains the mechanisms by which prices and levels of production are set.
In economics, supply relates to the quantity of goods or services that a producer or a supplier is willing to bring into the market at a particular price in a given time period, all other things being equal.
The law of supply states that the quantity of a commodity supplied varies directly with its price, all other factors that may determine supply remaining the same. The law of supply expresses the relationship between prices and the quantity of goods and services that sellers would offer for sale at each and every price. In other words, the higher the price of a product, the higher the quantity supplied. As the price of a commodity increases relative to price of all other goods, business enterprises switch resources and production from other goods to production of this commodity, increasing the quantity supplied.
Clearly the law of supply is the opposite to the law of demand. Consumers want to pay as little as they can. They will buy more when there is a price decrease in the market. Sellers, on the other hand, want to charge as much as they can. They will be willing to make more and sell more as the price goes up. In this way they can maximize profits.
The relationship between price of a product and its quantity supplied is represented in a table called a supply schedule. The supply curve is a graphic representation of the market supply schedule and the law of supply. Each point along the supply curve represents a different price-quantity combination, showing a direct relationship between the quantities of products that firms are willing to produce and sell at various prices, all non-price factors being constant. Sloping upward from left to right the supply curve reflects that producers supply more at a higher price and less at a lower price.

The supply curve enables producers to anticipate what the supply would be for those prices falling in between the prices that are in the supply schedule.
People often confuse supply with the quantity supplied. The difference between supply and quantity supplied is that
Supply represents the amounts of items that suppliers are willing and able to offer for sale at different prices at a particular time and place, all non-price determinants being equal.
The quantity supplied refers to the amount of a certain product producers are willing to supply at a certain price. A change in the price of the product will cause a change in the quantity supplied.
Price is an important determinant of the quantities supplied. The law of supply states that the amount offered for sale rises, as the price is higher. The quantity of pairs of cut jeans producers are willing to offer for sale rises, since their price is higher primarily because they need to cover the increased costs of production.
However, there are things other than price which affect the amounts of goods and services suppliers are able to bring into the market. These things are called the non-price determinants of supply.
As it has been mentioned a change in the quantity supplied caused only by a change in the price of the product. A change in supply is caused by a change in the non-price determinants of supply. They are:
Changes in the cost of production. Production costs relate to the labour costs and other costs of doing business used in production process. The cost of production is probably one of the most important effects on production process. An increase in the costs of any input brings about the lower output. Regardless of the price that a firm can charge for its product, price must exceed costs to make a profit. Thus, the supply decision is a decision in response to changes in the cost of production.
Changes in technology. Changes in technology usually result in improved productivity. Improved technology decreases production costs and therefore increases supply.
Changes in the price of resources needed to produce goods and services. If the price of a resource used to produce the product increases, this will increase the production costs and the producer will no longer be willing to offer the same quantity at the same price. He will want to charge a higher price to cover the higher costs.
Changes in the expectations of future prices. Changes in producers' expectations about the future price can cause a change in the current supply of products. If producers anticipate a price rise in the future, they may prefer to store their products today and sell them later. As a result, the current supply of a particular product will decrease.
Changes in the profit opportunities. If a business firm produces more than one product, a change in the price of one product can change the supply of another product. For example, automobile manufacturers can produce both small and large cars. If the price of small cars rises, the producers will produce more small cars to earn higher profits. They will shift the resources of the plant from the production of large cars to the production of small ones. Therefore, the supply of small cars will increase and a supply curve will shift outward. So, profit opportunities encourage producers to produce those goods that have high prices.
Changes in the number of suppliers in the market. Potential producers are producers who can produce a product but don’t do it because of relatively low price. If price of a product rises potential suppliers will switch over production to that product to make more profit. If more producers enter a market, the supply will increase, shifting the supply curve to the right.
Making a summary it is necessary to emphasize that the understanding of concepts of supply and demand provides an explanation of how prices are determined in competitive markets.
An important concept in understanding supply and demand theories is elasticity. Comprehension of elasticity is useful to understand the response of supply to changes in consumer demand in order to achieve an expected result or avoid unforeseen consequences.
In economics, the price elasticity of supply is the degree of proportionality with which the amount of a commodity offered for sale changes in response to a given change in the going price. In other words elasticity of supply is a measure of how much the quantity supplied of a particular product responds to a change in the price of that product.
Elasticity of supply works similar to elasticity of demand. Supply is elastic if a change in price results in a large change in the quantity supplied. On the other hand, if a great change in price brings about a small change in the quantity supplied, supply is called inelastic. There are some factors that determine price elasticity of supply. The most important of them are the ability of producers to change the amount of goods they produce, time period needed to alter the output and others.

1. A supply curve slopes upward from left to right, reflecting the fact that more of a product will be brought into the market at a higher price and less at a lower price.
2. According to the law of supply an increase in supply leads to a reduced price, while a decrease in supply causes a rise in price, demand remaining constant.
3. As a result of a shift in supply, there will be a new relationship between the price and quantity of a commodity supplied.
4. Since it costs more to produce additional items, producers will supply more only if they can charge a higher price.
5. Potential producers switch resources to production of a particular product, if its price increases, and enter the market for that product to maximise their revenues.
6. Changes in suppliers’ expectations cause supply curves to shift.
7. Companies that operate in highly competitive industries provide goods or services that are very elastic because current market condition does not enable them to charge a price they would like to.
8. Supply along with demand is one of the two key determinants of price but relates to the total amount of the goods available for purchase.
