⁶ It should be noted that in Sraffa's model, luxury goods that do not enter into the production of other commodities have no affect on relative prices and the rate of profits. They can, perhaps, be considered unproductive in Becker's sense. They have, however, a very specific, quantifiable meaning in Sraffa's analysis.
