Class 7 Social Science Chapter 12: Understanding Markets

A place for buying and selling

A market is where people come to buy and to sell. That is the whole definition, and it is wider than it first looks.

The same thing goes by several names. Bazaar. Haat, in Hindi. Marukatte, in Kannada. Your own region almost certainly has its own word.

It need not be a place at all

A market can be somewhere you walk to. It can equally be something you open on a phone, and that kind is growing fast.

Through markets, goods and services reach individuals, households and businesses. People have leaned on them to meet their needs and their wants for a very long time.

And they carry more than goods

One line in the chapter is worth holding on to. Markets connect people, traditions and ideas.

Keep it in mind. The chapter returns to it much later, and it explains why a market can matter to a family for reasons that have nothing to do with prices.

Needs, and wants

Two words are used precisely here, so it is worth being precise too.

A need is something a person must have in order to live. Food. Water. Clothing. Shelter. A want is something a person would like to have but can live without. The difference is survival, not importance.

A market in sixteenth-century Karnataka

For an example the chapter reaches back five hundred years, to the Hampi Bazaar in the Vijayanagara Empire.

It stood opposite the Virupaksha temple, and it was one of the empire's prosperous markets, in a capital that was a centre of flourishing trade.

What was sold there

Foreign visitors wrote the city down, and the lists they left are long.

Grains and seeds. Milk and oil. Silk. Animals, including cows, rabbits and horses. Even birds: quails and partridges. The Portuguese traveller Domingos Paes was struck by the range.

A second traveller, and a puzzle

Another Portuguese writer, Fernao Nuniz, described craftsmen working in the streets, and jewels and precious stones of every kind laid out for sale.

What stayed with him was the contradiction. The surrounding country was barren, and the market was overflowing, and he could not account for it.

What makes a market a market

Now the features. A buyer and a seller stand in every market. That much is obvious.

The third feature is the one that does the work. The two of them have to agree on a price before anything can change hands.

What a price actually is

A price is the figure a buyer will pay and a seller will take. Notice that both halves are needed.

A seller may name a number, but a named number is not yet a price. It becomes one when somebody agrees to it.

Getting there by argument

Buyers and sellers usually negotiate. They bargain, back and forth, until they reach something both can accept.

That is not a failure of the market. It is the market doing its work, with two people who want opposite things finding one figure between them.

The first guava scenario

Take the chapter's example. A seller wants eighty rupees a kilogram for his guavas.

Buyers may not be willing to pay it. A buyer who finds the figure too high will name the price he is prepared to pay instead. If the seller will not come down, nothing is sold.

The second scenario

Now swing the other way, to twenty rupees a kilogram.

Buyers are delighted; the seller is not. He may refuse, because at that figure there is no profit in it for him. A price that suits only one side is no more workable than the first one was.

The third scenario

Over time the price of guavas settles at forty rupees a kilogram, dear enough to be worth his while and cheap enough to be paid.

Both sides can live with it, which is exactly why it holds. And the seller learns something besides.

What the seller learns

From the three attempts he can judge roughly how many guavas buyers actually want, and bring that quantity next time.

So over time, the amount sellers offer and the amount buyers require together settle a figure that fits both of them at once.

Two everyday cases to test it on

Vegetables are cheaper late at night at a weekly market than during the day. Why?

The seller does not want to carry unsold vegetables home, and they will not keep. His willingness to accept less has risen as the evening wears on.

And one more

Garment shops cut the price of woollens heavily at the end of winter.

The reason is the same shape. Few buyers now want a sweater, and the shop would rather have the money than the stock. The figure moves because what each side is willing to accept has moved.

Scenario:

Three people sell mangoes at the same weekly market. The first asks ninety rupees a kilogram and holds firm all morning, and by noon he has sold two kilograms. The second asks thirty, sells out in an hour, and tells a neighbour he has made nothing on the day. The third asks sixty, bargains with everyone, settles at fifty five with most buyers, and goes home with an empty cart and a full purse. A watching pupil says the third seller was simply luckier than the other two.

Analysis:

Three prices and three outcomes, and an explanation that reaches for luck where the chapter offers a mechanism.

Activity:

Watch a vegetable seller for ten minutes and note any price that changes during a sale.

Title:

Run the three scenarios yourself

Safety:

No hazards here.

What You Notice:

The two settled figures are rarely the same, and that is the point worth noticing. The goods did not change, so the difference comes from how much each player was willing to accept, which is exactly what moves the price of vegetables late at night.

A market is a marukatte in Kannada and a haat in Hindi.

The Hampi Bazaar stood directly opposite the Virupaksha temple.

Foreign visitors to Hampi listed quails and partridges among the goods for sale.

A market needs three things: buyer, seller, agreed price.

Eighty too high, twenty too low, forty just right.

Markets are everywhere

Markets exist all around us, and they take a great many forms.

The chapter sorts them, and the sorting is worth getting right, because it asks two separate questions rather than one.

The first question: where do you meet?

A physical market is one you go to in person. You stand in front of the seller, hand over money, and carry the goods away. It is still the commonest kind by far.

What counts as a physical market

A weekly market, or a haat, where vendors line up vegetables, essentials and handicrafts on a cart.

A local market humming with people, selling street food and knick-knacks. And in cities and towns, a mall: a multi-storey building covering a large area, with stores inside it.

Meeting without meeting

Buyers and sellers no longer have to be in the same place. They can deal from wherever is convenient, even thousands of kilometres apart.

The tools are shopping apps and websites, opened on a phone or a computer, and built by businesses that offer a wide range of goods and services.

What arrives at the door

The list runs from books, clothes, furniture and groceries up to televisions, mobile phones and laptops, all delivered to your doorstep.

It is not only households, either. A manufacturer can buy components online to use as inputs for production, which are the materials fed in before anything finished comes out.

Services, too

Goods are not the whole of it. You can take an online class without stepping outside the house, and pay for it online as well.

But some services still need a person in the room. Tailoring is the chapter's example, and there are plenty more.

A market with no goods at all

One kind of market trades neither goods nor services, and it is worth knowing the name even before you study it.

That is the share market, also called the stock market. The chapter promises to return to it later in the year.

The second question: does it cross a border?

Now the other division entirely, and it has nothing to do with how the two parties meet.

A domestic market is buying and selling that stays inside the country's own borders. The chapter's example is pleasing: the paper for this very book came from big paper mills across India, and that transaction never left the country.

When trade crosses borders

International markets lie outside a nation's boundary. A seller in one country sends its products out to another, and a buyer in one country brings in products made elsewhere.

Exporting is sending out what your own country produced, for payment. Importing is bringing in what another country made.

Why the two questions are separate

Here is the part a reader can easily miss. The two divisions cut across each other.

Order a book from a shop in your own town through an app, and that is online and domestic. Order one from abroad and it is online and international. A shipload of crude oil arriving at a port is physical and international.

India's imports, on the map

The chapter prints a map of what India sends out and brings in. Taking the arrivals first.

Crude petroleum and fertilisers come from West Asia. Diamonds from Africa. Electrical equipment from Europe. Aircraft and their components from North America. Vegetable oils from South East Asia, and mineral ores such as copper from South America.

And India's exports

Going the other way, pharmaceuticals go to Africa, and engineering goods such as food-processing machinery and boilers to Europe.

Refined petroleum products go to West Asia. Outsourced services, software among them, go to North America. Chemical products go to South America.

The pair worth noticing

Look again at West Asia. Crude petroleum arrives from there, and refined petroleum products go back.

That is not a muddle. India buys the raw oil, refines it, and sells the finished product, which is a whole industry visible in two arrows on a map.

One striking figure

No country bought more vegetable oil than India did in 2024. Palm oil, sunflower oil and soybean oil among them.

Most of the palm oil comes from three countries: Malaysia, Indonesia and Thailand.

What that figure tells you

Ask why a country with a great deal of farmland imports so much cooking oil.

The answer is the point of the whole chapter. A market exists because people need goods they cannot produce for themselves, in the quantity they need them, and a border is no barrier to that.

Scenario:

A family makes four purchases in a single week. On Monday a parent buys tomatoes from a cart at the weekly haat. On Tuesday an uncle orders a laptop through an app, and it comes from a warehouse in the next state. On Thursday the family tailor is called in to take measurements for a wedding outfit. On Saturday a cousin working at a refinery mentions that a tanker of crude petroleum has docked, bought from West Asia. A pupil is asked to sort the four. The first and third are physical markets, she says. The second is an online market, and the fourth an international one. So that makes four kinds for four purchases.

Analysis:

A neat answer, one purchase to each box, and the neatness is exactly what gives it away.

Activity:

Sort five things bought at home last month by both questions at once.

Title:

Sort by two questions, not one

Safety:

No hazards here.

What You Notice:

The online-and-international box is usually the hardest to fill from your own life, and the physical-and-domestic box is usually crowded. That is worth noticing: the commonest kind of market is still the one you walk to, inside your own country.

The paper for this textbook came from mills across India, so that was a domestic transaction.

In 2024 India was the world largest importer of vegetable oils.

Most of the palm oil India buys comes from Malaysia, Indonesia and Thailand.

Two questions: where you meet, and whether you cross.

Export sends out; import brings in.

Who stands between you and the maker

A tomato does not travel from a farm to your kitchen in one step, and neither does a shirt.

Several participants keep a market running smoothly, and each of them is there because something would otherwise go wrong.

The wholesaler buys big

Start at the top. A wholesaler buys goods in large quantities, straight from the producer or the manufacturer.

Grains, vegetables and fruit, for instance, go to a wholesaler straight off the farm. The farmer sells once, in bulk, rather than hunting for a thousand buyers.

Where the goods wait

What is bought has to be put somewhere. The produce goes into large warehouses called godowns.

For things that spoil, a warehouse may need cold storage: a building held deliberately at a low temperature so perishable goods keep. From there the goods are brought to markets called mandis.

Other wholesale markets

It is not only food. There are wholesale markets for chemicals, for electronic items and components, for construction materials, for automotive parts, and more besides.

The pattern repeats wherever goods are made in quantity and sold in small amounts.

The retailer sells small

Wholesalers supply the shops and stores near where people live, and those shopkeepers are the retailers.

They sell to final consumers, which means us. Two things mark them off from wholesalers: the quantities are small, and the goods are meant to be used rather than sold on again.

Retailers of services

A retailer need not sell goods at all. Salons, cinemas and restaurants are retail too.

What retailers do, in a single line, is increase how easily households can reach goods and services.

When the wholesaler cannot reach

Now a real difficulty. A wholesaler may find it hard to reach a great many retailers, because of the distances involved and the terrain in between.

Distributors bridge that gap. They take goods from manufacturers and wholesalers and get them to the retailers.

A chain you have met before

If this feels familiar, it should. Those milk middlemen in the Grade 6 Amul story were doing this very job.

The structure repeats across every commodity, which is why it is worth learning once properly.

Online changes the middle

For online markets the chain is different, and the difference is in the middle, not at either end.

Manufacturers send bulk quantities straight to the warehouse of the business that runs the selling app.

What an aggregator is

That business is called an aggregator. It is a website or an app that gathers offers from many sellers and puts them in one place for a buyer.

A consumer picks from the app, and the aggregator packs the product and delivers it. One organisation has absorbed the wholesaler, the distributor and the shop.

A chain worth tracing: Surat

For a worked example the chapter goes to Surat, in Gujarat, which holds Asia's oldest textile market and is known as a textile hub.

Thousands of factories there make cotton and synthetic textiles.

Where the cotton comes from

Take cotton cloth. Raw cotton reaches Surat through cotton mandis from nearby states such as Maharashtra, and from other parts of Gujarat itself.

So the chain begins in fields some distance away, in more than one state.

Each stage is its own market

Here is the detail worth holding on to. The cotton becomes finished fabric by stages. Power looms weave it. Processing units dye it. Other steps follow.

And the product moves from one stage to the next through markets. There is a market for woven fabric, one for dyed fabric, and one for finished products such as sarees and ready-made garments.

What the wholesalers do there

The manufacturing units trade their finished goods on the wholesale market, and the wholesalers there are a crucial channel of supply.

Distribution to the small shopkeeper and to the big retail store is theirs to oversee, both here and abroad. They also judge how much each retailer needs.

Why that judgement matters

That last job is the one people forget when they call a middleman unnecessary.

By assessing what retailers require, wholesalers help makers hold the right amount of stock, and keep supply to the end consumer from being interrupted.

And the diamonds

One more thing about Surat. Besides textiles, it holds the largest diamond industry in the world.

About 1.5 million artisans cut and polish diamonds there, on an enormous scale. Trade flourished in the city from the sixteenth century onwards, helped by its position on the west coast, where ports and road networks grew up that still matter. Communities of skilled artisans have lived there for centuries, passing their craft down the generations.

Scenario:

A mango farmer sells his whole crop each year to a wholesaler who comes to the orchard, and he is sure he is being underpaid. One season he decides to sell direct instead. He hires a van, drives the crop to town, and spends four days finding buyers. He sells about half. The rest ripens in the van and is thrown away. His neighbour, who sold to the wholesaler as usual, earned less per crate but more over the season. The farmer concludes that selling direct is simply impossible for a small grower.

Analysis:

A fair experiment with a clear result, and a conclusion that goes further than the evidence does.

Activity:

Ask a local shopkeeper who delivers their stock, and how often.

Title:

Draw the chain for one real product

Safety:

No hazards here.

What You Notice:

Most people can name the shop and the maker and almost nothing in between, which is the point. The links you had to guess at are exactly the ones whose work is invisible when it is being done well.

Surat holds Asia oldest textile market.

About 1.5 million artisans cut and polish diamonds in Surat.

Trade began to flourish in Surat from the sixteenth century onwards.

Producer, wholesaler, distributor, retailer, you.

Godown stores it; a mandi sells it on.

What markets are for

Markets matter a great deal in people's economic lives, and the chapter sets out why plainly.

They make transactions between producers and consumers possible. And they let individuals, households and businesses reach goods and services that they need but cannot make for themselves.

A market you cannot find

Consider Aakriti. She is a professional artist who paints in oils on canvas, and her work is admired.

Her difficulty is that she cannot find buyers. She does not know where to sell her paintings, nor what price to ask for them.

Compare her with the guava seller. Guavas have many buyers and many sellers in any town, so a price emerges from all those attempts.

Artwork has few of either, locally. With no crowd of buyers and sellers, there is nothing to settle a price against, and that is a real problem rather than a failure of her painting.

Markets carry messages

Now something markets do that is easy to miss. Suppose a great many buyers begin asking for refrigerators that use less electricity.

Producers receive an indication of what consumers will buy. They start making energy-efficient refrigerators, and society gains from it. The buyers never wrote to a factory; the market carried the message for them.

More than money changes hands

Buying and selling is an economic activity involving money. But what happens in a market often goes well beyond asking about a product or haggling over a figure.

Relationships grow between buyers and sellers, and some last across generations.

Some families keep the same tailor, the same jeweller, the same doctor for decades, trusting each of them.

Many Indian families run an account with the local grocer and settle it at the end of the month. That arrangement rests on nothing but trust, and it is one of the quietest things a market does.

A market run by women

Ima Keithal, which means Mother's Market in the Meitei language of Manipur, stands in Imphal and is unlike most markets anywhere.

Roughly 3,000 women own and run every single shop in it.

What it sells, and what it does

On sale are vegetables and local produce, handloom and handicrafts, clothes including the traditional attire of Manipur, and whatever daily essentials the city and the country around it need.

It does two jobs at once. It provides employment, and so an important income for thousands of families. And it is a meeting place where people of different communities exchange ideas and share traditions.

A tradition at the counter

In south India, sellers of haldi and kumkum, which are turmeric and vermilion, hand the buyer a small quantity of each, separately, at no charge.

It is a mark of auspiciousness and a wish of goodwill. Nobody is paid for it, and that is rather the point.

Where the government comes in

Markets work through demand from buyers meeting supply from sellers. Demand is how much buyers will take at a given price; supply is how much sellers will part with.

Sometimes that arrangement works badly, and the government has a crucial part to play. It watches over the dealings between consumers and producers, and over whether a price is fairly arrived at.

Holding prices in bounds

The first job is price control, and it runs in both directions.

The government sets a maximum that a seller may charge for certain goods: a lifesaving drug has an upper limit on its price. It also sets a minimum for essential farm products such as wheat, paddy and maize, so growers do not make a loss. And it sets minimum wages, so employers pay fairly.

Why limits need care

A price limit is not free of risk, and the chapter says so.

Set a price too low and producers have no reason to produce at all. Set it too high and buyers are the ones who suffer. The limit has to be implemented with some care.

Testing before selling

The second job is quality and safety. The government sees that manufacturers meet the required standards when making goods or providing services.

Medicines are the example. The government lays down approval procedures for drugs, and tests samples to check that what was made actually meets the standard, so no consumer's health is put at risk.

Effects beyond the sale

The third job concerns what a market does to everybody else. Some goods are made in factories that may pollute.

Single-use plastics are the chapter's case: making them harms the environment and poses health risks. The government steps in with strict regulations to reduce such damage. It also runs systems to check the weights and measures on packaged goods, so the stated net quantity is honest.

Rulers protecting buyers is nothing modern. Kautilya's Arthashastra instructs traders in clarified butter to give the buyer a fiftieth part extra.

The reason is precise: some of the ghee stays stuck to the measuring can, and the extra makes up for it.

Goods nobody profits from

The fourth job is the simplest to state. Producers make things in order to earn a profit, and some things carry no profit at all.

A public park. A road. Policing. These are public goods, meaning anything open to everyone in a society, where use today leaves it no less available tomorrow. The government provides them. And a warning goes with all four jobs: too many rules can stop a market functioning properly.

Now the buyer's own turn

That is protection from above. The last section of the chapter is about what a buyer can do unaided, starting with a question about marbles.

You have 150 rupees and a competition against the next street. You would weigh the price, the size, the strength, perhaps the colours. That weighing is quality assessment, and every consumer has to do it.

Reading a packet

Take a one-kilogram packet of gram flour. A great deal is printed on it, and each item answers a question.

How much is inside: the net quantity. How long it lasts: the best before date, with the date of manufacture. What it costs at most: the MRP. Who made it: the name and address. What is in it: the ingredients list, the nutrition facts panel, and the allergen declaration. Which batch it belongs to, if something goes wrong. And the FSSAI mark with its licence number.

Four marks worth knowing

FSSAI stands for the Food Safety and Standards Authority of India. Where its symbol appears on a food packet, the government has tested what is inside and found it safe to eat.

ISI is next. The Indian Standards Institution mark is issued by the Bureau of Indian Standards, and you will find it on electrical appliances, construction materials, car tyres and paper. AGMARK, where Ag stands for agriculture, certifies farm produce: vegetables, fruit, cereals, pulses, spices, honey. And electronics carry a BEE star rating, from the Bureau of Energy Efficiency, where more stars mean less energy used.

What a mark is actually telling you

Be precise about this. Where a government agency has certified a product, on the item or on its packaging, what is being confirmed is that the thing meets the minimum standards of quality.

Minimum, not best. It is a floor, and that is still worth a great deal when you are standing in a shop with no way to test anything yourself.

And what other buyers know

Two last sources, and neither is official. A product's reputation influences what people buy, and reputation is built by word of mouth.

Have your own family ever bought something because a friend or a relative recommended it? Online, the same thing appears as reviews and feedback from other consumers, which help a shopper decide whether to buy.

Scenario:

A family needs a kilogram of gram flour. The first shop sells it loose from an open sack, cheaply, weighed on a balance the shopkeeper adjusts himself. The second sells a sealed packet at a higher price, printed with a net quantity, a best before date, an MRP, an ingredients list and an FSSAI mark with its licence number. A neighbour advises the loose flour, saying the sealed packet is the same flour with a logo added, and that the logo is just a way of charging more. The family buys the packet anyway, and is asked to explain why.

Analysis:

The same flour by weight, two prices, and a disagreement about what the printing is actually for.

Activity:

Find three certification marks in your own kitchen and note what each product is.

Title:

Audit a label

Safety:

Do not open or taste anything to check it.

What You Notice:

Most packets carry ten or more separate items, and the batch number is the one whose purpose is hardest to guess. It exists so that if something goes wrong, every packet from the same run can be traced at once.

About 3,000 women own and run every shop in Ima Keithal.

In the Arthashastra a ghee trader had to add a fiftieth part extra.

In BEE star ratings, more stars mean less electricity used.

Government: caps prices, tests quality, curbs harm, provides parks.

FSSAI food, ISI goods, AGMARK farms, BEE energy.
