Linear programming model and general reciprocity theorem in mathematical programming are used to ap-proach utility functions of six large-scale Russian (the Moscow Region) case farms representing different production patterns. Technological coefficients of linear programmes are defined by means...

In our previous paper, we derive the demand function in the form p=du(x)/dx and we apply the Weber-Fechner's law to the utility function and we obtain the demand function in the familiar form p=A/x. We compare our derivation of the demand function with the standard one. The differences are i)...

Given that demand for durable goods is not constant over time, we propose in this article a transformation of the utility function, which accounts for discrete time and for the effect of different levels of income in the utility of buying. With this, the original Coase paradox will collapse. The...

We apply the Weber-Fechner's law, which represents the relation between the magnitude of physical stimulus and the magnitude of psychological sense in human being, to the utility function. We conclude that the utility function of n-types of goods is of separable type...
