Dear lir J imp son,
Prof, Soraers wrote to me that he accepted the article
as an annex to my book but did not know whether the editor
agrees. I am waiting for his reaction.
Since the other papers included as annexes in my book
have been published elsewhere before, I wonder whether not i|y
my article could be published in Fconometrica and, somewhat
later, in my book on Econometrics. In that way both your
preference and my promise to Prof. Somers could be taken
account of. If you think this is duplication, I could understand your point of view and *huld then leave it to Prof.
Soraers to decide. If the editor v;ould not follow Prof, j^v .^
Somers' suggestion for publication in the book I would of sparse
course appreciate publication in Econometrica all the more.
Yours very sincerely.
