With standard Cobb-Douglas technology Y = K^a L^(1-a), marginal product = wage = (1-a)Y/L. If "a" goes up over time, wages will rise more slowly than average productivity. This is the idea of "capital-biased" technological change that e.g. Paul Krugman wrote about recently - I'm not saying that this is really what happened, but such an explanation would surely be consistent with MPT.<br /><br />And while I'm writing this, your criticisms of general equilibrium are pretty off-mark too. I'll just point out that your preferred Sraffa's model can be reinterpreted in general equilibrium framework (Hahn 1982, Mandler 1999), so it can hardly be considered "more realistic", at least on an abstract level. Of course a particular (with specific values for technology, etc.) Sraffian model could be more realistic than some particular GE model, but that would be an entirely different dicussion.<br /><br />F.

Since one of the things driving me mad is that economists in the 1960's took an interest in technological improvements, which always seemed sensible to me, and modern day economists seem to have no interest in expanding science and rtechnology. And I'd really like to know ehat changed their minds.mike shupphttps://www.blogger.com/profile/08383379836883992742noreply@blogger.comtag:blogger.com,1999:blog-1740670447258719504.post-36182432639337035692013-03-18T13:08:32.427-04:002013-03-18T13:08:32.427-04:00Not to mention you don't evaluate marginal pro...Not to mention you don't evaluate marginal productivity by looking at average productivity and average wages.Alex Tabarrokhttp://www.marginalrevolution.comnoreply@blogger.com
