Market
Utterances receive their value (and their sense) only in their relation to a market, characterized by a particular law of price formation. The value of the utterance depends on the relation of power that is concretely established between the speakers' linguistic competences, understood both as their capacity for production and as their capacity for appropriation and appreciation; it depends, in other words, on the capacity of the various agents involved in the exchange to impose the criteria of appreciation most favourable to their own products.
