VALUE IN ECONOMIC THEORY
To understand the centrality of value
in economic theory, consider these simple situations. If I exchange an apple
with another person who is willing to exchange it for a banana, what we have
engaged in is simple barter. And the reason why we have exchanged an
apple with a banana and vice versa is that the use value of the banana
is greater to me than that of the apple, and the opposite is true for my
counterpart. In barter, the essence of use value is evident: it is a relationship
between human need and objects. Use values are the objectification of
human needs.
Now consider a different situation. I
sell an apple for one dollar from my counterpart. Next, with the dollar
obtained, I purchase a banana from a third party. Here, the ultimate
outcome for me is the same: I have obtained the use value of a banana in
exchange for the use value of an apple. But the crucial difference
is that now I have achieved this outcome not through barter, involving
strictly use values, but rather through a monetary medium, one dollar. The
difference is that now what the apple and the banana have in common are no
longer the respective use values between the bartering parties, but
rather the exchange values of the apple and the banana which are socially
quantified in the monetary medium of one dollar.
In other words, what is happening in
this monetary exchange as against the barter is that now
the transaction involves exchange values which, unlike use values, no longer
relate purely to the subjective needs of the parties involved (two for barter)
but rather to the socially objective valuation of the exchanging parties
through the monetary medium. Thus, where the monetary medium is concerned, we
can see that exchange value is socially objective instead of being subjective
as in the case of barter. Exchange value removes the direct link between human
needs and objects by introducing money as filter between them and other human
beings. Money as exchange value has now become socially objectified use value
or wealth.
The question now is: - how is it
at all possible for two very different objects, with utterly incomparable use
values – an apple and a banana – to be equated not through direct use values (I
need a banana and my counterpart needs an apple, so we agree on the barter),
but rather through an abstract socially objective validated exchange value that
is fixed through the monetary medium at one dollar? What is the quality
that one dollar indicates which makes two utterly different objects measurable
and equivalent? This common quality measurable in a socially
objective manner we call “exchange value”. But what exactly is the substance,
the content - the essence, the quintessence, the quidditas - of
this “value”?
And further we may ask: what then is
the difference between use value and exchange value? It is not
sufficient to say that use values are subjective and exchange values are
socially objective – because surely there is a social dimension to use
values as well – that is why they are exchanged through barter just as exchange
values are exchanged through money. Indeed, it may be said that use values are
more socially significant than exchange values because they relate to the
actual organic needs of human beings as against the more mercantilist or
transactional or ephemeral desires of social agents who exchange objects for
money so as to realise more money than when the exchange began! Because the
ultimate aim of agents who engage in exchange through the monetary medium is
not so much, and often it is not at all, to obtain a final use value but rather
to realise a greater quantity of the monetary medium, of socially objective
value, than the one with which they began the exchange!
And yet we know that the objectification
of exchange value, the monetary medium, must also have an ultimate use
value or human need that justifies the whole process of exchange of exchange
values through money. The difference between use value and exchange value is
that with the former the focus is on the intrinsic objective usefulness
of the object, whereas with exchange value the focus is almost exclusively on
the extrinsic ability of the object to generate a profit, on its
“exchangeability”. Certainly, in both cases, the use value of the object plays
a role. But in the case of exchange value, use value is almost irrelevant or at
least comes a distant second to the ulterior motive of the ability of
the object to generate a profit. Hence, the contrast between the two kinds
of value could not be starker: use value is founded on human needs first and
foremost, on the limited and specific function and purpose of the object;
exchange value is founded almost entirely on the endless accumulation of
exchange value as a source of profit.
The next question then arises: what
exactly is the content of exchange value as a source of endless accumulation of
value or profit? In other words, what is the use value of exchange
value? What human needs does exchange value serve or satisfy?
