Paradox of value Totally Explained

Everything about The Paradox Of Value totally explained

The paradox of value (also known as the diamond-water paradox) is the apparent contradiction, or paradox, that although water is on the whole more useful, in terms of survival, than diamonds, diamonds command a higher price in the market. The economist Adam Smith is often considered to be the classic presenter of this paradox. Nicolaus Copernicus, John Locke, John Law and others had previously tried to explain the disparity.

Labor theory of value

Adam Smith explained the paradox by arguing that value had two different meanings: ť The one may be called 'value in use ;' the other, 'value in exchange.' The things which have the greatest value in use have frequently little or no value in exchange; and on the contrary, those which have the greatest value in exchange have frequently little or no value in use.

Furthermore, he explained the value in exchange as being determined by labor:
ť The real price of every thing, what every thing really costs to the man who wants to acquire it, is the toil and trouble of acquiring it.
Hence, Smith denied a necessary relationship between price and utility. Price on this view was related to a factor of production (namely, labor) and not to the point of view of the consumer. Proponents of the labor theory of value saw that as the resolution of the paradox.
The labor theory of value has lost popularity in mainstream economics and has been replaced by the theory of marginal utility.

Marginalism

The theory of marginal utility, which is based on the subjective theory of value, says that the price at which an object trades in the market is determined neither by how much labor was exerted in its production, as in the labor theory of value, nor on how useful it's on a whole (total utility). Rather, its price is determined by its marginal utility. The marginal utility of a good is its least important use to a person. The reasoning goes like this. If someone possesses a good, he'll use it to satisfy some need or want. Which one? Naturally, the one that takes highest-priority. Eugen von Böhm-Bawerk illustrated this with the example of a farmer having five sacks of grain. With the first, he'll make bread to survive. With the second, he'll make more bread, in order to be strong enough to work. With the next, he'll feed his farm animals. The next is used to make whisky, and the last one he feeds to the pigeons. If one of those bags is stolen, he won't reduce each of those activities by one-fifth; instead he'll stop feeding the pigeons. So the value of one bag of grain is equal to the satisfaction he gets from feeding the pigeons. If he sells that bag and neglects the pigeons, his least productive use of the remaining grain is to make whisky, so the value of one more bag of grain is the value of his whisky. Only if he loses four bags of grain will he start eating less; that's the most productive use of his grain. The last bag of grain is worth his life.
In explaining the diamond-water paradox, marginalists explain that it isn't the total usefulness of diamonds or water that matters, but the usefulness of each unit of water or diamonds. It is true that the total utility of water to people is tremendous, because they need it to survive. However, since water is in such large supply in the world, the marginal utility of water is low. In other words, each additional unit of water that becomes available can be applied to less urgent uses as more urgent uses for water are satisfied. Therefore, any particular unit of water becomes worth less to people as the supply of water increases. On the other hand, diamonds are in much lower supply. They are of such low supply that the usefulness of one diamond is greater than the usefulness of one glass of water which is in abundant supply. Thus, diamonds are worth more to people. Therefore, those who want diamonds are willing to pay a higher price for one diamond than for one glass of water, and sellers of diamonds ask a price for one diamond that's higher than for one glass of water.

Objectivism

One objection (raised by Objectivists, that's followers of philosopher Ayn Rand), is that the concept of marginal utility ignores the fact that items have some inherent properties that make them useful. The fact that the farmer has chosen to store grain in sacks and not pebbles, is because grain has the property of being edible, a property that pebbles lack.
