Also attributed to him is the creation of the term "marginal utility" (Grenznutzen)[5] due largely to the influence of Léon Walras and Vilfredo Pareto,[6] both of the Lausanne School. This has led some scholars to not consider his later works as belonging to the Austrian School. Even his disciple Ludwig von Mises said in his autobiography Memoirs (1978) that Wieser had misunderstood the gist of the subjectivism of the Austrian School and was actually a member of the Lausanne School.[6] However, in both he also presents a clear methodological individualism and a rejection of historicism of the German School, so at first blush it is difficult to justify his exclusion from the Austrian School.
