Term just price Definition: A somewhat archaic term developed by St. Thomas Aquinas that the price of a good should equal the worth generally agreed to by society. This is based on a notion of justice and fairness that goods should only be exchange for something of equal value or worth. For example, if ice cream readily sells for a dollar a scoop throughout the city, but one vendor charges two dollars, then this higher price would not be considered a just price. This view of a just price is relies on the view that each good has an intrinsic value which is inconsistent with modern views of markets, prices, and subjective values.
