Hi Ajit, The numeraire certainly ain't money! Re, your discussion of 93 percent correlation: if there is a 93 percent correlation over a number of 'observations', then of course there may be subsets of observations with zero correlation, and some with negative correlation too. If you think that science is no more and no less than the positing of functional relations then we disagree on our respective notions of science. I think science is the attempt to grasp real material forms (structures, mechanisms, powers, processes etc., like H20 and the powers of water, say). You interpret Sraffa to deny functional relations in economics. I take it this leaves open the possibility that non-functional relations can be established? So you have published on the labour time / price relation. Please, please, please, summarise in a paragraph for us... Do you think there is no correlation (as your discussion of 93 percent seems to imply)?

It says, "Prelude to a critique of economic theory". What does he mean by "economic theory"? He means the neoclassical economic theory because that is the predominant economic theory of the time. Why do I say "economic science"? It is because the neoclassical economic theory is designed as science such as physics. It works on functional relations that are rooted in the notion of mechanical causality. One of the points, which is very controversial and not accepted by most of the Sraffians, that I'm making is that Sraffa was attacking economics as science. In my reading, he favored economic theory to be "descriptive" rather than "predictive". That is what I'm pointing to when I say the uniqueness of Standard commodity shows the limitation of economic as science. As a matter of fact, even Amartya Sen defends LTV only from the descriptive perspective and not "predictive". By the way, numeraire does not mean money. Sooner you stop confusing the two, the clearer your theoretical understanding of economics will become. ______________________________ > > You write: 'Yes, but the statement that it has "a > positive > relationship" does not make sense.

The question of proportionality does not arise here. What I'm saying is that prices have changed but the labor content of the two commodities has remained the same. In this case where is the positive relationship? The relationship is neither 93, nor 9 or 3 percent, it is ZERO. So where does it leave your proposition. I'm not interested in getting sidetracked by reference to Stigler. I think he has misinterpreted Ricardo and I have said that here and there in some footnotes. But that's a separate issue. _________________________ > > You continue, 'Now let me hummer you > further.

It is one thing to say that changes in prices are of small magnitude due to changes in distribution, where as changes in prices are of large magnitude due to changes in labor content on the basis of a theory that determines the relative values of the commodities in the first place and completely different thing to say that there is positive relation between labor-time and price changes without having a theory that determines the prices in the first place. ________________________ > > You write, 'as far as what I think about > labor and all this--may be some other time'. > > Ajit this isn't fair!:) Come on, I've 'owned up'... > what are your > thoughts? _______________________ Well, they are available in public domain. You can look at the entry on "labour theory of value" in Readers' "Guide to Social Sciences" and also my paper in 'Value and the World Economy Today', Westra and Zuege (eds.).
