up to move from a given utility level to any bundle. Therefore the benefit function associates to any bundle of goods … another bundle that lies on a given indifference curve. This enables one to derive an inverse demand function which is defined … as the support price of this associated bundle. The classification of goods between complements and substitutes is then …
