Commerce department figures on Friday showed that total sales in 2010 were up 6.8 per cent from 2009, marking the sharpest such increase in more than a decade…
Industrial output is up by 5.9 per cent year-on-year.
Yet the labor market is still "eh." Here is more, but again note it is wrong to reject the AD factor altogether, though it seems to be becoming less relevant over time. Arguably AD and AS are interacting in unusual and presumably deleterious ways.
I have read too many blog posts attacking a caricatured version of either RBC theory or a narrowly defined notion of "structural unemployment" which requires excess demand for labor in significant parts of the economy. As Arnold Kling points out, the labor market shock can be asymmetric in its effects.
From a different direction, here is Scott Sumner criticizing the recalculation argument. I read Scott as establishing the conclusion that both AD and AS must be at work.
