Note 201 — Chapter XI · THE ULTIMATE RELATION OF COST TO VALUE
Reading edition
He stated it in the form of an admission that, besides changes in labor cost, there can be a second cause of variations of the exchange ratios between commodities, namely a rise or fall of the general rate of interest. He first stated the second cause to be a fall or rise of the general rate of wages, but in his view this is equivalent to a rise or fall of “profits,” i. e., interest. See ante, chap. v, §§ 7 and 8.
