Andrew T, a welcome from a lurker on this list.
Could I make a question on followings?

What is your definition of "labour quality" or "quality of labour time"? Does 
it simply mean mutiplier of labour time to simple labour of a segment (by
education, age, sex, occupation,...)?
I tend to think wage rates for individual workers or for segments are not
proportional to hourly value created. For example, we saw that wage rates for 
high-educated office workers had increased much relative to those for
factory workers in '80 in Japan. I don't believe this is the result from
more value added by the former. Rather I would say this proves the change
of management policy regarding change of labour-capital relation and/or
change of other social backgrounds.
I won't criticize any attempt to overcome the limitation of datas in order
to develope empirical study. Just a question.
