For example, a ration of water might be used to sustain oneself, a dog, or a rose bush. Say that a given person gives her own sustenance highest priority, that of the dog next highest priority, and lowest priority to saving the roses. In that case, if the individual has two rations of water, then the marginal utility of either of those rations is that of sustaining the dog. The marginal utility of a third unit would be that of watering the roses.

It may be no more than a purely ordinal change. [7] [8] The notion that marginal utilities are diminishing across the ranges relevant to decision- making is called “the law of diminishing marginal utility” (and also known as a Gossen 's First Law”). However, it will not always hold. The case of the person, dog, and roses is one in which potential uses operate independently — there is no complementarity across the three uses. Sometimes an amount added brings things past a desired tipping point , or an amount subtracted causes them to fall short. In such cases, the marginal utility of a good or service might actually be increasing . The law of supply and demand states that in a competitive free market , the price for a good will move towards the level where supply and demand for that good are equal. The Production Possibility Frontier Consider the case of an island economy that produces only two goods: wine and grain. In a given period of time, the islanders may choose to produce only wine, only grain, or a combination of the two according to the following table: Production Possibility Table Wine (thousands of bottles) Grain (thousands of bushels) 0 15 5 14 9 12 12 9 14 5 15 0 The production possibility frontier (PPF) is the curve resulting when the above data is graphed, as shown below:
