In the Dumenil-Foley approach, the ratio of labour-value-added (LVA) to
money-value-added (MVA) is the value of money (VM), and its inverse is the
monetary expression of value. This is all in value added terms; it is not
the ratio of total value to total price, which is in gross rather than net
terms. It is this latter to which I think (but am not sure) that Andrew is
more sympathetic.
Also, the value of labour-power per hour of labour-power hired (VLP) is the
wage rate per hour (w) multiplied by VM. So
VLP = wVM
Multiply both sides by L. On the left hand side interpret L as the number of
hours of labour-power hired, and on the right hand side as the number of
hours of labour worked, which needs a strong underlying assumption.
Then VLP.L = wL.VM where wL is total wages W. So
VLP.L = W.VM
Hence total wages multiplied by the value of money is total variable capital.

Unfortunately, when I wrote
When V is multiplied by the value of money it is then the total wage bill
I should have written
When V is multiplied by the monetary expression of value it is then the
total wage bill.

Does that answer your query?
