Vide Alfred Marshall, Principles of Economics, London, 1907, vol. i. p. 124.
"If I put a letter in the pillar-box rather than walk half a mile to deliver it by hand, it is clear that I value the service at one penny at least, and if its true value is to be taken at less than a penny, it must be assumed that some one would have carried the letter for less than a penny if the Post Office monopoly had been absent. But to deal thoroughly with this question it would be necessary to enter on a discussion of the Austrian theory of value and Marshall's conception of 'consumer's rent.'"—E. Cannan (Memoranda on Classification and Incidence, p. 163).
