In the consumer’s theory, a crucial problem is to determine the substitution effect and the revenue effect in the case of one good price’s modifing. There exists two theories due to John Richard Hicks and Eugen Slutsky which allocates differents shares of the total change of the consumption...

In this paper we shall give a generalization of Cobb-Douglas, CES, Lu-Fletcher, Liu-Hildebrand, VES, Kadiyala production functions. We compute the principal indicators like the marginal products, the marginal rate of substitution, the elasticities of factors and the elasticity of substitution....

The article treats the reduction of quadratic forms to the normal form by Gauss's method taking in discussing various determinants whose behavior will determine its nature. Applications of this method are illustrated for the most common production functions: Cobb-Douglas and CES.
