PaulC:
It depends upon how you construct the i/o matrix. If, it is constructed on
a per industry basis, then the intsensity of labour is irrelevant
and the labour power and labour vectors can be used indistinguishably.

This is because wat counts as simple labour is labour of average intensity
and skill, which can only be meaninfully defined within the context of a
single industry. If on the other hand the input output table is
constructed on a per firm basis then the intensity of labour is very relevant,
since the firms with the more intense labour will tend to have a higher physical
productivity and higher profits.
