Good morning, I have been reading a book in which the author said that "the supermarket is not a market, because despit the large number of buyers, the seller is unique".
So, I've been wondering because according to me, even if the market has just a one seller, we can consider it as a market. Then, if we consider the competition on this market, there's only one seller and if we consider that this supermarket is the only one in a country, we could say that it's a monopolistic market (no competition).
What do you think ?
