Also called the rate of commodity substitution. Marginal utility—The additional utility obtained from one additional unit of a commodity, the amounts of all other commodities held constant.

A ll t he p oints on t he contract curve are Pareto efficient, so how do we determine which distribution of the two g oods ma ximizes s ocial w elfare i n o ur si mple t wo-person s ociety? To answer this question, we begin by converting the commodity consumption of our t wo co nsumers i nto a m easure o f t heir r elative u tilities. 1 that at point 3 consumer A has more of both goods X and Y and at point 1 consumer B has more of both goods. At point 2 t he g oods a re e venly d istributed. A ssuming t hat co mmodity co nsumption is equivalent to utility, we can use this information to construct a second diagram showing the relative utilities of A and B at each point on the contract curve.
