The global properties of the two minflex Laurent flexible functional forms

Abstract The minflex Laurent flexible functional form is a special case of a second-order Laurent series expansion. The minflex Laurent, when constructed in square roots, is called the minflex Laurent (ML) generalized Leontief. The minflex Laurent (ML) translog model is the minflex Laurent in logarithms. We find that the regular region of the ML translog is most often even larger than that of the ML generalized Leontief model, except when substitutability is very low. We previously have shown that the regular region of the ML generalized Leontief is substantially larger than that of the usual translog and generalized Leontief models.
