What is 'Supply'

Supply
The fundamental economic concept that states the total amount of a specified product or service that is available to customers is known as ‘supply.’ It is very closely related to and goes hand in hand with demand. When supply exceeds demand for a product or service, the prices of said product fall. This is known as the law of supply and demand. Their relationship highly affects the price of goods and is a very important topic in the field of economics.

What is Supply?
Supply is related to the price of the products, given that there is an incentive to supply at a higher price, as higher prices produce greater revenue and profits. Companies always want profit and, therefore, are more likely to manufacture more products at higher prices. When the price of goods or services is low, the supply is low, and when the price is high, the supply is also high. Therefore, significant price changes would also affect the equilibrium in the economic market.

Understanding Supply
The supply and demand relationship forms a solid basis for modern economics. Every product or service has its supply and demand in the market. Therefore, those products also have supply and demand patterns based on cost, utility, and preference. For example, suppose there is a significant demand for a particular good, making people willing to buy the product at a higher price. In that case, the companies will work to increase the supply. As soon as there is a high increase in supply, we see the prices fall if the demand remains the same. In an ideal case, the economic market will reach an equilibrium point where supply becomes equal to demand at a certain price. At this specific point of equilibrium, company profit becomes maximized.

As long as the equilibrium point is maintained, manufacturers keep maximizing profits, and customers maximize utility. Any push in supplies in the market will lead to companies losing profit and therefore reduce supply. This will lead to a fall in prices until an equilibrium is reached again at some point.

There are a few factors of supply for goods and services. These factors are:

• Price of goods or service
• Price of production
• Price of Input
• Production units’ number
• Technology of production
• Producer expectation
• Policies of Government

Manufacturing companies who provide the supply have to be quick to expect a change in prices and then react accordingly to changes in demand. Unfortunately, despite the best analysts in the industry, a few market factors make it hard to predict these changes accurately.

Basics of Supply
The basics of supply have their foundations in mathematical formulas and their applications. Even though anything in demand and is sold in the economic market is called supply, the term is generally used for products, goods, and services. The most important factor for supply is the price of the product. If a product’s price increases, the supply of the product will also increase. The price of related goods and input prices like energy cost, cost of raw materials, and labour also increase the product's total selling price.

The conditions of the production of the goods of supply are also important. Government regulations and policies like environmental laws, labour laws and market policies also play an important role in affecting supply. These lead to a change in the number of suppliers and expectations in the economic market.

In microeconomics, the supply equation and its respective function show the relationship between supply and the factors that affect it. For example, a supply curve expresses the relationship between the prices of a product and the quantity of the supplied product.

The law of supply and demand, which is one of the fundamentals in economics, describes the interaction between the supply of goods by firms and consumer demand. These principles help us determine suppliers' reactions to price and demand change and how that affects the overall economic market.

The various types of supply are:
Short-term supply: The ability of consumers to buy products is restricted by available supplies. They cannot buy beyond the supplied goods.

Long-term supply: The factor of availability of time when demand changes which gives the supplier a way to adjust to the quick change in demand.

Joint supply: The supply of products produced and sold jointly.

Composite supply: The supply of a product through its different sources, where the product serves more than one purpose.

Market supply: The overall desire and capability of suppliers to supply the market with specific products regularly.

Can you give an example of supply in economics?
The concept of “supply” in economics can be easily explained with the help of an example. Suppose, at Rs. 100, a fruit supplier supplies five apples. At Rs. 90, the supplier will supply just four apples. At Rs. 80, the supplier will supply three apples and so on. This shows that the fall in the price of apples decreases the supply of the same and vice versa.

Why is supply important?
Supply is essential because it ensures that enough goods are produced so that the consumer demand for those goods is maintained. Usually, if supply is lower than demand, the price of that commodity will increase. This supply schedule or curve determines how much of a good is produced at a certain price level.

How does supply affect a business?
Supply helps a business to ensure that a certain number of their produced companies are made available to the market at different price levels to meet the needs of consumer demand. If there is an oversupply, the price of that product will decrease. If there is an under-supply, the price of that product will increase. Supply affects the profit margin of a business.
