Homogeneity and Supply
考察了Gorman类供给函数的同质性性质，发现同质性对函数形式施加了很强的限制，这些形式有助于检验可加性与同质性。
Abstract Supply functions in the ubiquitous Gorman class are examined for their homogeneity properties. Homogeneity places surprisingly strong restrictions on functional forms. These forms facilitate testing of aggregability given homogeneity or homogeneity given aggregability or testing both.
