&gt; But WHICH rate of profit and WHICH THEORY of the rate of profit? <br
/>&gt; Whether or not this theorem is true depends on one&rsquo;s theory
of the rate <br />&gt; of profit. It may be true for one theory of the
rate of profit, but <br />&gt; not true for other theories of the rate of
profit. <br />&gt; <br />&gt; The TSSI and the Okishio theorem are based
on DIFFERENT rates of <br />&gt; profit. The Okishio theorem is based on
linear production theory and <br />&gt; simultaneous determination and the
TSSI is based on temporal <br />&gt; determination. The Okishio theorem is
true in terms of its own theory <br />&gt; of the rate of profit, but it
is not true in terms of the temporal <br />&gt; theory of the rate of
profit. As Anders said in a recent post: &ldquo;The <br />&gt; premises of
Okishio is clearly different from Marx&rsquo;s.&rdquo;&nbsp;<br /><br />Hi
Fred:<br /><br />There&nbsp;are&nbsp;many theories of profit rate
determination, including (but not limited to)&nbsp;:<br /><br />a)
Okishio's &nbsp;theory of the profit rate.&nbsp;<br /><br />b) the TSS
theory&nbsp;of the profit rate.<br /><br />c) Marx's theory of the profit
rate.<br /><br />You are saying above that a) and b) are different.&nbsp;
I agree with you. In any event, that's<br />obvious and
non-controversial.<br /><br />However, for the TSSI claims to have
validity --&nbsp; since it claims to be an interpretation&nbsp;<br />of
Marx -- b) must&nbsp;equal c).&nbsp;&nbsp;&nbsp; If b) does not equal c)
then -- even if&nbsp; a) does not equal c)<br />--&nbsp; the TSSI claims
fail.&nbsp; <br /><br />In solidarity, Jerry
