What Is Value? (And Who Decides?)
"Price is what you pay. Value is what you get." — Warren Buffett
The Ring That Was Worth a Kingdom
In the summer of 1947, as India was being torn apart by Partition, millions of families packed whatever they could carry and crossed newly drawn borders. Some carried gold. Some carried deeds to land they would never see again. Some carried nothing at all.
There is a story — told in many versions, because many families lived it — of a woman from Lahore who fled with her family to Delhi. She carried, stitched into the hem of her sari, a gold ring. It had been her grandmother's. It was not particularly large or ornate. In Lahore, in ordinary times, a jeweler might have appraised it at fifty rupees.
But on that train, packed with frightened people who had not eaten in two days, she traded that ring for three rotis and a cup of water for her children.
Fifty rupees worth of gold. Three rotis and some water. Was it a fair trade?
Here is the thing: in that moment, on that train, it was. The ring could not feed her children. The rotis could. The value of that ring was not some number stamped on it by a jeweler in peacetime. Its value was what it could do for her, right then, in that place, under those circumstances.
And the person who had the rotis? They now had gold — which would be worth a great deal once they reached safety.
Both sides gained something they valued more than what they gave up. That is the deepest secret of value: it is not a number. It is a relationship between a person, a thing, and a moment.
Look Around You
Think of something you own that has little monetary value but that you would never sell. A letter from someone you love. Your grandmother's recipe book. A photograph. Now think of something expensive that sits unused — a gadget you bought and barely touched, clothes with tags still on them.
Which is worth more? To whom? And who gets to decide?
The Oldest Question in Economics
What makes something valuable?
This sounds like a simple question. It is not. It has occupied the greatest minds in economics for centuries, and they still have not fully agreed.
Let us start with what seems obvious. Water is essential for life. Without it, you die within days. Diamonds are pretty stones. You can live your entire life without ever touching one.
And yet — a glass of water costs almost nothing. A diamond costs a fortune.
This puzzle was first articulated clearly by Adam Smith in 1776, and it has haunted economics ever since. He called it the paradox of value:
"Nothing is more useful than water: but it will purchase scarce anything; scarce anything can be had in exchange for it. A diamond, on the contrary, though it has scarce any use-value, will purchase a great deal." — Adam Smith, The Wealth of Nations (1776)
How can something essential be cheap while something unnecessary is expensive?
The answer, it turns out, is not one thing. It is several things layered on top of each other, and different economists have peeled different layers.
Two Kinds of Value
Before we solve the paradox, we need to understand a distinction that goes back to Aristotle — yes, people have been thinking about this for that long.
Use-value is the usefulness of a thing. Water has enormous use-value. It quenches thirst, grows crops, cleans wounds. A blanket has use-value on a cold night. Medicine has use-value when you are sick.
Exchange-value is what you can get for a thing in trade. A diamond has high exchange-value. So does a piece of land in Mumbai. So does a rare painting, even if you personally find it ugly.
These two kinds of value often diverge wildly.
The air you breathe has infinite use-value — you cannot live without it for more than a few minutes. Its exchange-value is zero. Nobody will pay you for ordinary air.
A rare postage stamp might have zero use-value — you cannot eat it, wear it, or shelter under it. But collectors will pay thousands for it.
USE-VALUE vs EXCHANGE-VALUE
===========================
WATER DIAMOND
┌─────────────────┐ ┌─────────────────┐
│ Use-value: │ │ Use-value: │
│ ████████████████ │ (HIGH) │ ██ │ (LOW)
│ │ │ │
│ Exchange-value: │ │ Exchange-value: │
│ ██ │ (LOW) │ ████████████████ │ (HIGH)
└─────────────────┘ └─────────────────┘
AIR RARE STAMP
┌─────────────────┐ ┌─────────────────┐
│ Use-value: │ │ Use-value: │

│ │ │ │
│ Exchange-value: │ │ Exchange-value: │
│ │ (ZERO) │ ████████████████ │ (HIGH)
└─────────────────┘ └─────────────────┘
Why the gap? That is the question.
Understanding why use-value and exchange-value diverge is one of the most important things economics can teach you. Because the gap between them is where exploitation happens — and also where opportunity lives.
The Labor Theory: Value Comes from Work
One of the oldest answers to "what creates value?" is this: labor.
If a potter takes a lump of clay worth one rupee and spends a day shaping it into a beautiful pot, that pot is now worth fifty rupees. Where did the extra forty-nine rupees of value come from? From the potter's skill and labor.
This idea has deep roots. It appears in the thinking of John Locke, who argued in 1689 that when you mix your labor with something in nature, you create value and therefore have a right to own it.
Adam Smith developed it further. He argued that the "real price" of everything is the toil and trouble of acquiring it. The reason a deer might trade for two beavers in a hunting economy is that it takes twice as long to catch a deer.
David Ricardo refined it in 1817: the value of a good is determined by the total labor required to produce it, including the labor that went into the tools and materials.
And Karl Marx took it further still. In Das Kapital (1867), Marx argued that all value comes from human labor. When a factory owner pays a worker fifty rupees for a day's work that produces goods worth two hundred rupees, the difference — one hundred and fifty rupees — is "surplus value," extracted by the owner. This, Marx said, is the fundamental mechanism of exploitation under capitalism.
The labor theory is powerful. It captures something real. When you buy a hand-woven Banarasi sari, you are buying months of a weaver's life — the skill passed down through generations, the hours bent over the loom, the artistry in every thread. That labor is the core of the sari's value.
But the labor theory has problems.
If value comes purely from labor, then a bad potter who takes a week to make an ugly pot has created more value than a skilled potter who makes a beautiful one in a day. That does not match reality.
And what about a diamond found lying on the ground? Almost no labor — but enormous value.
What about land? Nobody made the land. Yet land in South Mumbai sells for more per square foot than almost anywhere on Earth.
The labor theory captures something true — that human effort creates much of what we value — but it cannot explain everything.
What Actually Happened
In Soviet Russia, where the labor theory of value was official doctrine, planners tried to set prices based on how much labor went into each product. The results were often absurd. Bread was priced so low that farmers fed it to their pigs — it was cheaper than grain. Meanwhile, goods that nobody wanted sat in warehouses because their "labor value" said they should be expensive. A system built on the labor theory alone could not figure out what people actually needed and wanted.
The Utility Theory: Value Comes from Desire
In the 1870s, three economists working independently — William Stanley Jevons in England, Carl Menger in Austria, and Leon Walras in Switzerland — proposed a radically different answer.
Value, they said, does not come from the labor that went into a thing. It comes from the usefulness — the utility — that the thing provides to the person buying it.
And here is the key insight: marginal utility. The value of something depends on how much of it you already have.
Think about water. The first glass of water when you are dying of thirst is worth everything you own. The second glass is worth a lot. The tenth glass is worth less. The hundredth glass? You would pay nothing — you might even pay someone to take it away.
This is why water is cheap. Not because it is unimportant, but because it is abundant. Most of us have access to enough water that the next glass — the marginal glass — is worth very little to us.
Diamonds are expensive not because they are inherently more valuable than water, but because they are rare. The marginal diamond — the next one available — is scarce, so people will pay a great deal for it.
THE DIAMOND-WATER PARADOX — SOLVED?
=====================================
Value of each additional unit:
WATER DIAMONDS
Worth ^ Worth ^
to you | to you |
|* |*
| * | *
| * | *
| ** | **
| *** | ***
| **** | ****
| ****** | ******
+──────────────────> +──────────────────>
Quantity available Quantity available
You have LOTS of water, You have FEW diamonds,
so the next glass is so the next diamond is
worth very little. worth a great deal.
TOTAL value of all water >>>>>> TOTAL value of all diamonds
MARGINAL value of water <<<<<< MARGINAL value of a diamond
Price reflects MARGINAL value, not TOTAL value.
The utility theory elegantly solved the diamond-water paradox. And it captured something the labor theory missed: the same object can have different value to different people at different times, because value is subjective.
A bottle of water at your home: five rupees. That same bottle in a desert: five hundred? Five thousand? Your life savings?
But Wait — Is Value Really Just in Your Head?
The utility theory swung the pendulum all the way to the other side. If the labor theory said value is entirely objective — determined by the hours of work — the utility theory said value is entirely subjective — determined by individual desire.
Both are half-truths.
Consider a Tata Nano and a Mercedes-Benz. The Mercedes costs twenty times more. Does it provide twenty times more utility in getting you from point A to point B? Of course not. Both have four wheels, an engine, and seats. The Nano might actually be more useful in crowded Indian cities.
So why the price difference? Because the Mercedes provides something beyond transportation — status, comfort, identity, a signal to the world about who you are. Is that "utility"? The theory says yes, but now we have stretched "utility" to include social meaning, which is something quite different from individual desire.
And consider this: why do people desire diamonds at all? Partly because the De Beers company spent a century running one of the most successful marketing campaigns in history. The slogan "A Diamond Is Forever" was invented in 1947 by an advertising agency. Before that campaign, diamond engagement rings were not common in most of the world.
Value was manufactured. Desire was created. Then the market priced the diamond based on a desire that did not exist until someone invented it.
"The value of a thing is the amount of laboring or work that its possession will save the possessor." — Henry George
"Value is not inherent in goods but in the relation of goods to the needs of man." — Carl Menger
The Same Object, Different Values
Let us do a thought experiment. Take a simple object — a liter of clean drinking water — and see how its value changes with context.
THE SAME LITER OF WATER — DIFFERENT VALUES
=============================================
Context │ Value to you │ Why?
────────────────────────────┼─────────────────┼──────────────────────
At home, tap running │ Nearly zero │ Abundant, easy access
────────────────────────────┼─────────────────┼──────────────────────
At a cinema hall │ ₹20-50 │ Captive audience,
│ │ no alternatives
────────────────────────────┼─────────────────┼──────────────────────
On a train in summer │ ₹50-100 │ Hot, limited supply
────────────────────────────┼─────────────────┼──────────────────────
Lost in the Thar Desert │ Everything │ Survival at stake
────────────────────────────┼─────────────────┼──────────────────────
In a flood │ Negative │ Too much water is a
│ │ disaster
────────────────────────────┼─────────────────┼──────────────────────
Bottled, branded, │ ₹20 (same │ Brand creates
"Himalayan spring" │ water, higher │ perceived difference
│ price) │
────────────────────────────┼─────────────────┼──────────────────────
In a village with │ Hours of labor │ Scarcity + no market
no clean water source │ per day │ access
────────────────────────────┼─────────────────┼──────────────────────
Same water. Same H₂O molecules. Wildly different values.
The object did not change. YOU changed. The CONTEXT changed.
This tells us something profound. Value is not a property of things. It is a property of the relationship between things, people, and circumstances.
The liter of water did not become "more valuable" in the desert. It became more valuable to you, in that moment, under those conditions. Value is relational.
Value as Social Agreement
Here is where it gets really interesting. Much of what we call "value" is not about individual utility at all. It is about social agreement.
Why is gold valuable? Not because you can eat it or build shelter with it. Not because it is particularly useful (though it does have some industrial applications). Gold is valuable because human beings, across cultures and centuries, have agreed that it is valuable.
This sounds circular — and it is. Gold is valuable because we believe it is valuable, and we believe it is valuable because it has always been valuable. The circle sustains itself through collective belief.
The same is true for money. A five-hundred-rupee note is a piece of paper. Its use-value is nearly zero. Its exchange-value — five hundred rupees of goods and services — exists only because everyone in India agrees to honor it. If tomorrow everyone stopped believing in the rupee, the note would be worth nothing.
This is not a flaw in the system. It is the system. Value, at the deepest level, is a social agreement. And social agreements can change.
Consider saffron. In medieval Europe, saffron was worth more than gold by weight. It was used as medicine, dye, and spice, and it was extremely scarce in northern climates. Wars were fought over saffron shipments. Today, saffron is still expensive, but it is no longer worth more than gold. The social agreement shifted as trade routes opened and alternatives became available.
Consider tulips. In the Netherlands of 1637, a single tulip bulb sold for the price of a house. People genuinely believed tulip bulbs were that valuable. Then, in February 1637, the belief collapsed. Prices fell by ninety percent in weeks. The tulips had not changed. The social agreement had.
The Power Behind the Price Tag
If value is a social agreement, then the question becomes: who gets to shape that agreement?
This is the political economy of value — and it matters more than any theory.
When the British East India Company bought Indian muslin at rock-bottom prices and sold it in London at enormous markups, the muslin's "value" in India was kept artificially low through colonial power. The weavers who made it — some of the most skilled textile workers in world history — were paid a pittance. The value they created through their labor was captured by merchants and colonial administrators an ocean away.
When a brand like Nike buys shoes manufactured in Vietnam for three dollars and sells them for one hundred and fifty dollars, where is the value? In the labor of the Vietnamese worker? In the design by the American team? In the brand image built by billions of dollars of advertising? In the desire created in the consumer's mind?
The answer is: in all of these. But the distribution of that value — who gets paid what — is not determined by any natural law. It is determined by power.
"All that is solid melts into air, all that is holy is profaned, and man is at last compelled to face with sober senses his real conditions of life, and his relations with his kind." — Karl Marx, The Communist Manifesto (1848)
Value in Indian Thought
The concept of artha — the very word that titles this book — offers a richer understanding of value than either the labor theory or the utility theory alone.
In the Indian philosophical tradition, artha means material prosperity, but it is embedded in a larger framework. The Arthashastra of Kautilya (roughly 300 BCE) treats economic value not as an abstraction but as a practical matter tied to the well-being of the kingdom. The value of grain is not just its market price but its strategic importance for food security. The value of a trade route is not just the tolls collected but the prosperity it brings to surrounding villages.
Buddhist economics, articulated in modern times by E.F. Schumacher, suggests that the value of work is not just the product it creates but the dignity and purpose it gives the worker. A livelihood that produces useful goods while enriching the person who produces them has more "value" than one that produces useless goods while degrading the worker — even if the market prices say otherwise.
Gandhi's concept of swadeshi — self-reliance — was at its core an argument about value. When you buy cloth woven in your own village, the value stays in the village. When you buy imported cloth, the value flows out. The cloth might be the same. The value, in Gandhi's framework, is profoundly different.
"A thing has value only when it is useful and when it has been produced with just means." — Mahatma Gandhi
The Deeper Paradox
Let us return to the diamond-water paradox with fresh eyes.
The marginal utility explanation is clever and partly true. But it hides something important.
Water is cheap in places where it is abundant and where there are systems — reservoirs, pipes, purification plants, government subsidies — that ensure supply. In places without these systems, water is not cheap at all. In parts of Rajasthan and Bundelkhand, families spend hours every day fetching water. The effective "price" of water — measured in time, labor, and health consequences — is enormous.
The diamond-water paradox is really a paradox of privilege. If you live in a city with functioning water infrastructure, water seems cheap. If you live in a village without it, the paradox does not exist. Water is the most expensive thing in your life.
And diamonds? Their high price is maintained partly through artificial scarcity. De Beers historically controlled the global diamond supply and deliberately restricted the number of diamonds released to the market. The "scarcity" that makes diamonds expensive is partly manufactured.
So the diamond-water paradox is not just about marginal utility. It is about infrastructure, power, monopoly, and who gets to control supply.
This is the recurring lesson: value is never just an economic concept. It is always tangled up with politics, power, history, and social structure.
Think About It
A farmer grows rice that feeds hundreds of people. A social media influencer makes videos about luxury handbags. The influencer earns ten times more. What does this tell us about how our society measures value?
Clean air has no market price. Does that mean it has no value? If a factory pollutes the air in your village, how would you calculate the value of what was lost?
Your grandmother's recipe for dal might be the most delicious thing you have ever tasted. A famous restaurant charges eight hundred rupees for a bowl of dal that is not as good. What determines the "value" of each?
When a pharmaceutical company holds a patent on a life-saving drug and charges a price that most patients cannot afford, is it capturing value or destroying it?
The Many Faces of Value
Let us gather what we have learned.
Value is not one thing. It is many things at once:
Value is labor. The hours, skill, and effort that go into creating something are real. When a Kashmiri artisan spends months carving a walnut wood table, that labor is embedded in the object. The labor theory is not wrong — it is incomplete.
Value is utility. The usefulness of something to a specific person in a specific moment is real. The marginal utility framework explains much of how prices work in markets. But utility is shaped by culture, advertising, and power — it is not some pure, individual calculation.
Value is scarcity. When something is rare relative to demand, its exchange-value rises. But scarcity can be natural (there is only so much gold) or manufactured (De Beers limiting diamond supply, a landlord holding land empty to drive up prices).
Value is social agreement. Gold, money, brands, degrees — much of what we value, we value because everyone around us agrees to value it. These agreements are powerful, but they can shift.
Value is power. Who gets to capture value — the worker who makes the shoe, the designer who imagines it, the brand owner who markets it, the retailer who sells it — is determined not by natural law but by bargaining power, legal frameworks, and social structures.
Understanding this is not just academic. It is practical. Every time you buy something, sell something, negotiate a salary, vote on a policy, or argue about what matters — you are making claims about value. The more clearly you see value for what it is, the better your decisions will be.

The Bigger Picture
We started this chapter with a woman trading a gold ring for three rotis on a train during Partition. That story contains everything.
The ring had one kind of value in peacetime Lahore — a beautiful heirloom, worth a modest sum in exchange. On that train, its exchange-value collapsed and its use-value was zero. The rotis had modest exchange-value in an ordinary market. On that train, they were worth gold.
Value shifted because the world shifted. And the world shifts all the time — not always as dramatically as Partition, but constantly. A drought changes the value of water. A new technology changes the value of an old skill. A change in fashion changes the value of a fabric. A government policy changes the value of a crop.
If you understand value only as a number on a price tag, you will be confused by the world. If you understand it as a living, shifting relationship between people, things, circumstances, and power — you will begin to see clearly.
In the next chapter, we will follow value as it moves — through supply chains, across borders, from villages to cities, from the hands that make things to the pockets that profit from them. Because understanding what value is matters less than understanding where it goes.
And where value goes, so goes the wealth of nations.
"The real price of everything, what everything really costs to the man who wants to acquire it, is the toil and trouble of acquiring it." — Adam Smith, The Wealth of Nations (1776)
