Question 5 The QG Group produces both hiking boots and insoles. Let the total cost functions associ- ated with these products be: C(QBao) I 3 'l' @ C(0,Q1) 2 3+6)? C(QB, Q1) = 4 + @ + Q12 where C(QB, 0) represents the cost of producing hiking boots alone, C(O, Q1) represents the cost of producing insoles alone7 C(QB, 62;) is the joint cost of producing boots and insoles together, QB is the quantity of boots produced, and Q1 is the quantity of insoles produced a) Without drawing the relevant cost functions, are there economies of scale associated with the production of hiking boots? Use calculations to support your reasoning. b) Why might there be economies of scope associated with the production of hiking boots and insoles? Briey explain. 0) Are there in fact economies of scope associated with the production of hiking boots and insoles? Use calculations to support your reasoning
