Note 331 — Chapter III · : THE PESSIMISTS

Ricardo gives a slightly different explanation. “If with a capital of £1000 a tenant obtains 100 quarters of wheat from his land, and by the employment of a second capital of £1000 he obtains a further return of eighty-five, his landlord would have the power at the expiration of his lease of obliging him to pay fifteen quarters, or an equivalent value for additional rent, for there cannot be two rates of profit.” (Principles, ed. Gonner, p. 48.) He means to say that if profits fall because new capital is less productive than old, rent must necessarily appear, because by definition rent is what remains of the produce after deducting profits and wages. This explanation closely resembles that one given by West in his Application of Capital to Land, published in 1815, and Ricardo was not above acknowledging his indebtedness to West.
