Dear-Steindl, 
I am very grateful Indeed for your comments on 
ray paper. I am also Sorry that I made the reading of the 
paper more difficult hy the error on page 12, where I 
/ y > 
intended to put down the inequality 'V 1 - m —- r >0 
rather than <1. However, your query as to page 15 is simply 
answered hy the inequality 1 
1 + 
$ 
1 - a 
nf 
l-a 
mentioned at the top of that page. / As I see that it was 
easy to miss ?t I am displaying it now more prominently /, 
I have rep\Vdsed now page 21 as to make clear that I compare 
my theory with such theories that assume a priori a constant 
degree of utilisation of equipment. 
I have in the meantime developed somewhat the 
argument on the transfer of profits from old to new equipment. 
I shall try to publish the paper in the Economic Journal but 
they may not accept it because I already published there once 
a piece on a similar subject. In this case I shall send it to 
the Review of Economic Studies. 
I received some cutt|rflngs from the Europo. - Verlag 
on the German tr slation of my book. There is only one/from 
die Weltwoche Zutrich/ that goes into the substance and this 
is fairly negative. I enclose it as an interesting material 
for the reflection on our profession / compare especially 
the two sentences I marked /. 
I am very well and I have fully resumed my lectures 
and seminars. Right now I enjoy fortnightly vacation. 
How are you getting on ? You may tell that in detail 
Sachs who takes with him this letter. 
With best regards from myself and Ada 
Yours
