G'day Mike & Jim, I'm guessing total factor productivity is wrong in as far as it frames the actual producer as but a factor of production - one of them little ways our order unconsciously factors its bankrupt ethics/values into its 'objective science', eh? Or is Jim also talking about incommensurability here - reminding us that we can't compare TFP across time, space or sector because of stuff like technological levels and relative labour costs. I'd love to know exactly what the case against TFP is, anyway. It gets talked about all the time here - we still have a few shards of family silver left in public hands in this country, and 'efficiencies' are always the reasons we're given to justify our handing it over to the privateers (and sitting by while government wipes out unions, too, for that matter). Be nice to be a little more theoretically and rhetorically equipped for the uneven contests that ensue ... Cheers, Rob.
