The other training centre is in Liverpool. The manager of the Liverpool centre is
meeting with the manager of the London centre to discuss the possibility of the
London centre using trainers from the Liverpool centre instead of external trainers.
They have agreed this arrangement in principle, but need to agree a daily fee that
the London centre should pay the Liverpool centre for these of its trainers.
It has been estimated that if trainers from the Liverpool centre are used in London,
the variable costs incurred will be £200 per day, plus £250 per day for travel and
accommodation costs. These costs will be paid by the Liverpool centre.
Required
Identify the optimal charge per day for the use of Liverpool trainers by the London
training centre, in each of the following circumstances:
(a) assuming that the Liverpool centre has spare consulting capacity
(b) assuming that the Liverpool training centre is fully occupied charging clients
£750 per trainer day
(c) assuming that the Liverpool training centre is fully occupied charging clients
£1,100 per trainer day.
58 Shadow price
Division A supplies a special chemical to Division B, another profit centre in the
same group. The output capacity for making the special chemical in Division A is
limited.
The variable cost of making the chemical is $500 per kilo.
There is no external intermediate market for the chemical.
Division B uses the chemical to manufacture a tablet. Each tablet uses ten grams
of the chemical.
Sales demand for the tablet exceeds the production capacity of Divisions A and B.
The selling price for each tablet is $10. Further variable processing costs in Division
B to make the tablet from the special chemical are $2 per tablet.
Required
(a) Calculate the shadow price of each kilo of the special chemical. (The shadow
price of the special chemical is the amount by which total contribution would
be reduced (or increased) if one unit less (or more) of the chemical were
available.)
(b) Identify the ideal transfer price.
(c) Suggest whether this transfer price will provide a suitable basis for
performance evaluation of the two divisions.
