monopsony

Origin

From Ancient Greek μόνος (mónos, “alone, solitary; singular, unique”) + ὀψωνέω (opsōnéō, “to buy fish or victuals in general”) + -y, modelled after monopoly. ὀψωνέω is from ὄψον (ópson, “delicacies”) + ὠνέομαι (ōnéomai, “to buy, purchase”). The English word was coined by British classics scholar Bertrand Hallward (1901-2003), and popularized by British economist Joan Robinson (1903-1983) in her book The Economics of Imperfect Competition (1933): see the quotation.
