How do sellers decide the new price when supply is high?

In one line
When supply is high, sellers usually lower the price to attract buyers.
The rule
When the supply of a product increases and demand stays the same, the price usually falls.
There is no single formula, but in economic models, this is shown as: P = D(S) where:
P = price
D = demand (how much people want)
S = supply (how much is available)
Let's understand it simply
Imagine you are at a vegetable market. If every shop has a huge pile of tomatoes, but not many people want to buy them, what happens? Sellers worry the tomatoes will spoil. To sell them quickly, they shout lower prices. If one seller drops the price, others must follow, or buyers will go to the cheaper stall. This is how high supply leads to lower prices.
How it works
Sellers notice there is a lot of the product (high supply).
Fewer buyers are interested, or demand stays the same.
Products may spoil or become old if not sold soon (like vegetables or sweets).
Sellers lower the price to attract more buyers.
Buyers see the lower price and buy more, helping sellers clear their stock.

The story behind it
This idea comes from the basic law of supply and demand. Economists have studied markets for hundreds of years. They saw that when goods are plenty, prices fall, and when goods are scarce, prices rise. This helps keep the market balanced. The supply and demand model is one of the first things students learn in economics.
Where you see it in real life
Vegetable market after a bumper harvest: Too many onions, so prices drop.
Diwali sweets after the festival: Shops have extra sweets, so they sell at discounts.
Clothes at the end of season: Shops have leftover stock, so they announce sales.
Mangoes during peak season: So many mangoes arrive that sellers lower prices.
Cricket bats after a big tournament: Extra stock, so shops offer deals.
Why it matters
Helps you understand why prices change in the market.
Useful for business owners to set prices smartly.
Important for buyers to know when to get the best deals.
This idea is the base for many topics in economics and is used in exams and real business decisions.
Common mistakes
Thinking sellers always set prices high: In reality, they must adjust to what buyers will pay.
Forgetting about demand: If demand also increases, prices may not fall even if supply is high.
Believing prices drop instantly: Sometimes, it takes time for sellers to notice and change prices.
Remember it
When supply goes up but demand does not, price comes down — like a sale after a festival.
Check yourself
If there are too many mangoes in the market, what will likely happen to the price?
The price will go down because supply is high.
Why do sellers lower prices when supply is high?
To attract more buyers and sell their extra goods before they spoil or become outdated.
What happens if both supply and demand increase together?
The price may stay the same or change only a little, depending on which increases more.
Quick recap
High supply usually leads to lower prices if demand stays the same.
Sellers lower prices to sell goods quickly and avoid losses.
This is called the law of supply and demand.
You see this in markets, shops, and during sales.
Prices do not always drop instantly; it can take time.
