My response to Paul C's points is

I'm still working from memory (my copy of F+M is in deep storage at
the moment -- but surely their claim is that the rate of profit and
rate of wage bill will be gamma, not the profit share?

If I'm wrong, I'd be grateful for a reference.

I'm happy with the idea that s/v is in practice a non-degenerate
random variable tightly concentrated round 1.

Just checking, but is this company data, or what?

Locke's test implements the Lukacs Theorem idea involving the
characterisation of the gamma and is your starting point if you want
to go beyond a Kolmogorov-Smirnov g.o.f. test (but see Shapiro and
Chen (2001) for comments and alternatives).

at the OPE-L archive and bring myself up-to-date...

Quite -- however, I find that 50:50 Earl Grey:English Breakfast
provides sufficient impulse to get me out of the house in the morning
