Value is like beauty, it's an eye of the beholder thing
"
Value 'in use' is the
usefulness of this commodity, its
utility. A classical
paradox often comes up when considering this type of value. In the words of Adam Smith:
"The word VALUE, it is to be observed, has two different meanings, and sometimes expresses the utility of some particular object, and sometimes the power of purchasing other goods which the possession of that object conveys. 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.
"Nothing is more useful than water: but it will purchase scarce any thing; scarce any thing can be had in exchange for it.
"A diamond, on the contrary, has scarce any value in use; but a very great quantity of other goods may frequently be had in exchange for it. (
Wealth of Nations Book 1, chapter IV)
"Value 'in exchange' is the relative proportion with which this commodity exchanges for another commodity (in other words, its
price in the case of
money). It is relative to labor as explained by Adam Smith..."
