Abstract

In the vernacular, ‘efficiency’ typically concerns means. I can choose efficient rather than inefficient means to accomplish my ends. Or more generally, I can be efficient or inefficient in allocating my limited resources. If we could measure the aggregate utility or welfare of a society, as in Benthamite utilitarianism, we could say that a society is efficient in an analogous sense: it uses effective institutions to achieve the greatest possible welfare. But the normative notion of efficiency commonly in use in social and political theory today is about social choices without aggregative welfare measures. Efficiency is invoked as an alternative to such aggregative measures.
