JUSTIFICATION OF THE USE OF PROPERTIES OF INEQUALITIES IN THE QUESTION OF FORMING PRICE INDICES

Studies on the formation of price indices, taking into account the economic situation, have never lost their relevance. The number of proposed methods for constructing indices is in the tens. Therefore, in addition to analyzing specific methods, their classification is necessary. To do this, you need to introduce general rules for describing the family of index generation methods. The paper proves inequalities for the numerical values of the indices obtained by different methods used for cutting off unsatisfactory methods that give offsets, establishes acceptable methods that are adequate to the best economic conditions. . Based on the analysis carried out, a notation system was introduced that was introduced to classify and describe various numerical methods. Special attention was paid to identifying systematic inequalities arising from the formulas for calculating indices, establishing obviously unsatisfactory methods, for which an analysis of methods for calculating indices that establish a regular bias was used. On the basis of the conducted studies, it was confirmed that the presented approach, which is the most preferable in calculating price indices, in the case of using methods based on baseline data taken from the price of products and the volumes of these products in a specific time period. The analysis confirms the adequacy of theoretical calculations, as well as the fact of the use of additional initial information in the case of the formation of analytical indices.
