Generalized Leontief Cost Function--Elasticities 221 TABLE 7.3 Hicks­Allen Elasticities for Generalized Leontief Cost Model Parameter KL KE KM LM EM LE Cross-Price Elasticities, ij 6.84 -1.98 -0.87 1.04 0.15 11.14 Parameter KK LL EE MM Own-Price Elasticities, ii -5.50 -1.27 -13.72 -0.09 In this case, Hicks­Allen partial elasticities of substitution for a general dual-cost function with n inputs are computed as ij = C*C ij =C i *C j , (7.58) where i, j are the first and second partial derivatives of the cost function with respect to input prices (p , p ) and i, j = 1, , n.
