unit costs Suppose the firm's eost CUlVe is given by the expression C(ql''h) = G(ql) +

H(q:z} + J(ql''l2), where eaeh plOduet's marginal eost is strietly positive. Verify that holding ql eonstant, and with J(~,'l2) a nonzelO eonstant, the unit eost of the first varies with output of the second if we use units of output or relative separable eost to alloeate the joint eost.
