Автор предлагает на основе существующей методологии построения индексов (аксиоматического, экономического и стохастического подходов) решение проблемы адекватности статистических измерений динамики потребительских цен в случае, когда в результате изменения цен в потребительской корзине относительно дорогой товар заменяется покупателем на относительно более дешевый. В статье обосновывается использование формулы Торнквиста, обладающей лучшими свойствами по сравнению с другими формулами, применяемыми при построении гиперболических индексов. На основе методологии и данных Росстата произведен расчет индекса потребительских цен для России по формуле Торнквиста с использованием квартальных групповых индексов цен и долей потребительских расходов на уровне страны. Для оценки результатов эмпирических апробаций был рассчитан индекс потребительских цен, определенный по формуле Ласпейреса, с использованием тех же квартальных данных, что и индекс Торнквиста. Значения индекса цен по формуле Торнквиста в большинстве случаев ниже, чем показатели динамики цен, полученные по формуле Ласпейреса. Это заключение обосновано как теоретически, так и эмпирически и подтверждено для России. Однако в силу несоблюдения условий плавных трендов цен в отдельных кварталах различие между значениями индексов Торнквиста и Ласпейреса оказывается существенно большим, чем представлено в эмпирических исследованиях в других странах. Индекс потребительских цен, рассчитанный по формуле Торнквиста, в системе показателей статистики цен в России можно определить как показатель, уточняющий основной индекс потребительских цен. Расчет его значения необходим для реалистичного описания процессов, происходящих на потребительском рынке.</p></abstract><trans-abstract xml:lang="en"><p>The article reflects the author’s position on the adjustment of the so-called substitution bias, which affects the value of the consumer price index, currently calculated using the Laspeyres formula. The author proposes a solution to the problem of the adequacy of statistical measurements of the dynamics of consumer prices in the case when, as a result of changing cost of the consumer basket, a buyer replaces a relatively expensive product with a relatively cheaper one. This solution is based on the existing index construction methodology (axiomatic, economic and stochastic approaches). The article substantiates the use of the Törnqvist formula, which has better properties in comparison with other formulae used in the construction of superlative indices. The authors calculated the Törnqvist price index for Russia based on Rosstat methodology and data using country-level quarterly group price indices and shares of consumer spending. To evaluate the results of empirical testing Laspeyres price index was compiled using the same quarterly data as the Törnqvist index. The values of the Törnqvist price index in most cases are less than the price dynamics obtained according to the Laspeyres formula. This conclusion is proved both theoretically and empirically, and it is confirmed for Russia as well. However, due to the non-observance of the conditions of smooth trends in consumer prices, the difference between the values of the Törnqvist and Laspeyres indices is significantly larger in certain quarters than that presented in empirical studies in other countries. Consumer price index, calculated using the Törnqvist formula, in the system of indicators of price statistics in Russia can be defined as an indicator that specifies the main consumer price index. Calculation of its value is necessary for a more realistic description of the processes taking place in the consumer market.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>индекс стоимости жизни</kwd><kwd>индекс потребительских цен</kwd><kwd>формула Ласпейреса</kwd><kwd>эффект замещения</kwd><kwd>формула Торнквиста</kwd><kwd>гиперболический индекс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cost-of-living index</kwd><kwd>consumer price index</kwd><kwd>Laspeyres formula</kwd><kwd>substitution bias</kwd><kwd>Törnqvist formula</kwd><kwd>superlative index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Козлова М.А.
