Frank Fetter and his contributions have been overlooked for the most part, including various theories of rent, interest, price, exploitation, and their foundations and relations to the subjective theory of value. Fetter was seen as one of the leading Austrians, only to be surpassed by Mises himself a few decades later, more specifically in the area of subjective value theory. Matthew McCaffery has been an active revivalist of Fetter's ideas, relationships, contentions, and contributions.
