832. J. M. Keynes to Harrod , 9 September 1938 [a]

[Replies to 827 , answered by 834 ]

9 September 1938

Dear Roy,

I quarrel with the first sentence in your letter of the 6th, where you write that in any warranted position . [1] This seems to me to be wrong in its dimensions. I suggest that the equation should run or if you like where is the rate at which income has increased. J stands for time. [2]

Otherwise I await your revised draft. I return the enclosed, [3] since I had kept a copy of it.

As regards Price History, the best plan, I think, would be if you will report the result of your negotiations and what proposals are feasible. I sent your previous letter to Austin, [4] and we are both agreed in being against any important contribution, in view of our other commitments. The question of the number of Memoranda we can take from the London and Cambridge Service is much mixed up with this, and others who are interested in these Memoranda may have their views.
