How does the GDP measure productivity? All it measures is aggregate prices. If the same worker can produce more goods, and the price drops, looking at the aggregate price doesn't tell you diddly about productivity. I suspect that there is no way to unambiguously measure productivity, even if 'productivity' itself could be meaningfully defined. It is relatively clear that SB is right in there being at least two kinds of productivity, a unit labor productivity measured in widgets produced by an individual worker's hour of labor, and an overall productivity measured in some kind of total output divided by some kind of total labor. I don't see an alternative to using prices and money for this, but this adds its own new array of measurement problems. In the simplest unit productivity case, an individual is enabled to increase his unit productivity by being provided with a machine to increase his output. But even this has unaddressed measurement issues. What if the machine is really just an enclosure to hide the work of a dozen undocumented workers inside? Any real machine actually does enclose the production of other workers in the manufacture of the capital production equipment, so the hidden workers may not be that far off. In the end productivity is a means to an end, and not a goal in and of itself. The real goal is an improved standard of living, and every ongoing economy achieves this on an ongoing basis, due to the fact that changes to production are continually made, and are retained if they improve things, and rejected if they do not. To the extent that a real, even if unmeasured, productivity increase must sit somewhere behind an improving standard of living, productivity growth does not depend on technology advances, but rather simply on man's choices to improve his lot and economize on the utilization of all kinds of resources.
