This paper argues that, as far as theories of value and money are concerned
, Man: and Menger have more in common than has been traditionally maintaine
d. Each of them had his own abstract concept of value, distinct from labour
or utility and prior to prices. Moreover, both proposed theories of value
form and provided explanations of the origin of money. These concepts and t
heories can hardly be found in the works of Smith and Ricardo, nor in those
of Jevons and Walras, because they were primarily concerned with the deter
mination of exchange ratios. Furthermore, Marx and Men,ber become more shar
ply divided owing to their similarities. They shared many questions to whic
h they offered opposite answers.
