Whether or not welfare reform incentivized higher rates of labor participation it can't explain why a combination of low unemployment and relatively higher real wage didn't drive inflation up in and of themselves. And it seems to me that in classical theory reforms that served to drive up labor participation (which arguably welfare reform did) by increasing labor supply should have driven down labor price. In isolation anyway. Now you might be Abe to rescue monetary policy based on NAIRU if you could make the argument that classical NAIRU built in the assumption of a fixed supply of labor and that forcing more workers into the market and so suppressing wages simply offset the inflation effects of more people working. Theoretically of you could drive average labor compensation right down to subsistence levels you could achieve full employment while not driving inflation on goods actually consumed by capital. (BTW approximately the situation in Early Modern Britain when only the poor-and rich peoples horses-ate oats while wheat and meat were priced out of their diets altogether). But that theoretical out falls to pieces if you have more labor participation AND higher real wage and yet repressed inflation. Clearly there must be a missing piece.<br /><br />And in retrospect that missing piece is productivity. That is the way you beat goods inflation in the face of more people working at higher real wage is by inflating the goods supply at a faster rate than the combined effects of new employment and increased real wage.<br /><br />So no your argument did not assume productivity improvements. On the other hand it advanced no mechanism by which greater labor supply via welfare reform didn't result in either lower wage or higher inflation.<br /><br />Plus we could complicate everything by pointing out that standard measures of unemployment (e.g. U-3) mostly exclude welfare recipients to begin with. That is people who don't have jobs and in the absense of reform wouldn't be looking for work are not technically 'unemployed'. This welfare reform should have driven up U-3 while suppressing real wage. Which if it would have happened might have served to rescue NAIRU. But since by the data it didn't have that actual net effect leaves me scratching my head.Bruce Webbhttps://www.blogger.com/profile/13222670342780912788noreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-87675667386261788492012-02-18T04:54:37.136-05:002012-02-18T04:54:37.136-05:00Bruce, I just suggested that welfare reforms might...Bruce, I just suggested that welfare reforms might have reduced NAIRU.

But as some of those same commenters have noted the end result is all good for the bankers.<br /><br />The NAIRU debate fell out along the same lines, although data and theory were at best in uneven alignment, at least Central Bank policy served the interest of that part of the bond market that were more concerned with bond PRICE as opposed to savers looking for YIELD.<br /><br />You could sum this philosophy up as "First Do No Harm (to Billionaire's Bond Portfolios)". And you don't have to posit straight out dishonesty and still less evil, instead a lot of conventional economic theory seems designed to care for and feed capital stock. As if national wealth always and everywhere translated to national well-being.<br /><br />And it is not just NAIRU and Austerity, you see the same dynamic working among Free Trade absolutists. I mean who could quarrel with more wealth worldwide? (Except the 90% who aren't sharing much in those gains).<br /><br />It is less evil than it is a fundamental blind spot.Bruce Webbhttps://www.blogger.com/profile/13222670342780912788noreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-16270167264920861452012-02-17T11:37:08.955-05:002012-02-17T11:37:08.955-05:00Ralph,

Seems to me that Econ 101 appeals to 'supply and demand' suggest the effect should be in the opposite direction, more competition at the lowest wage level serving to drag down compensation at immediately higher levels.<br /><br />(BTW Barkley, the particular 'captcha' style used by this site is ridiculous, not everyone has 18 year old eyes or superlative powers of pattern recognition, sheesh)Bruce Webbhttps://www.blogger.com/profile/13222670342780912788noreply@blogger.comtag:blogger.com,1999:blog-4900303239154048192.post-54675916835089934812012-02-17T01:47:38.540-05:002012-02-17T01:47:38.540-05:00Barkley although I agree with your theoretical exp...Barkley although I agree with your theoretical explication, I find a different explanation in praxis.<br /><br />For my entire lifetime economic theories that posit NAIRU have at the same time served the material interests of what were known 50 years ago as the 'Coupon Clippers' but now perhaps as the 'Invisible Bond Vigilantes'.<br /><br />That is while there are theoretical arguments while policies that lead to higher levels of employment and real wage would lead to capital flight, there doesn't seem to be a lot of evidence that this works in practice. In particular violations of NAIRU haven't always led to inflation, and persistent fears that such inflation is in the cards and will inevitably lead to such capital flight (eeeek, the Chinese will liquidate Treasuries!!!!!!) haven't necessarily led to effects visible in actual capital markets. For example the TV told me today with amazement that both France and SPAIN had successful bond offerings YESTERDAY.<br /><br />Yet in the face of a couple decades of historical data and a persistent Faith in various forms of EMH there is still a demand for monetary and fiscal policy that I the short term serves the interest of the Bond market.<br /><br />Gosh it is almost like modern capitalism was organized around exploiting market power relations to maximize individual and class interest. Could it really be that capitalists are not committed to Utilitarian Greatest Good outcomes?
