EVALUATION METHODS OF IDENTIFICATION INCOME DEMAND ELASTICITY COEFFICIENTS

Abstract

This paper presents different methods of income demand elasticity coefficient evaluation and also verification of these methods. It was showed, that the best statistical adaptation for research of income influence for demand measure by expenditure have the function with asymptote. The next substantial verification, and also intuitive feeling related to consumer behaviours showed, that the best imitate of food expenditures evolution got in the case of Working model (hyperbolic and logarithmic).
