Summary:

The Austrian conception of marginal utility differs from that of mainstream economics. Whereas the mainstream explains diminishing marginal utility in terms of changes in one’s psychological state-​-​the declining pleasure brought by additional units of a good-​-​the Austrian explanation is not psychological but formal. For Austrians, a good’s utility is connected to our perception of its ability to help us achieve the ends we value, and diminishing marginal utility is a consequence of the fact that we apply additional units of a good toward achieving ends we value less.
