В статье исследуется жесткость цен на продовольственные, непродовольственные товары и услуги. Использованы ежедневные данные онлайн-ритейлеров Москвы за период с февраля 2019 года по май 2020-го. Обнаружено, что средний период неизменности цен составляет 19,5 дня. Распространены малые изменения цен: так, доля изменений цен, не превышающих 5% в абсолютном выражении, составила 34% всех изменений цен и 39% изменений, не связанных с распродажами. Кроме того, наблюдается значительная гетерогенность в частоте изменений цен: так, частота изменения цен на продукты выше, чем на непродовольственные товары, а стоимость услуг меняется реже всего. Наблюдаемое поведение цен демонстрирует, что их изменения зависят и от времени, и от состояния экономики. На зависимость от времени указывает, например, резкий рост вероятности изменения цен на 335-й и 353-й день их неизменности. Этот факт подтверждает выводы ряда зарубежных исследований о том, что их изменение более вероятно в конце и начале года. Проведенный анализ также показывает, что в марте — мае 2020 года фирмы стали изменять цены чаще и на меньшую величину — очевидно, в связи с ростом неопределенности из-за пандемии коронавируса. Если с марта по май 2019 года повышение цен наблюдалось в 50,2% случаев их изменения, то за аналогичный период 2020 года — в 62,7% случаев. Увеличилось количество дней с повышением цен — с 65 до 84 (из 92 дней марта — мая). Таким образом, частота изменений цен определяется как временем, так и ситуацией в экономике.</p></abstract><trans-abstract xml:lang="en"><p>The article studies price rigidity for food, non-food products and services based on daily data of online retailers in Moscow collected for the period from February 2019 to May 2020. It was found that the average price invariance period was 19.5 days. In addition, there is significant heterogeneity in the frequency of price changes: food prices change more often than non-food ones, and the cost of services changes the least often. The observed price behavior confirms the implications of time- and state-dependent models. The dependence on time is indicated, for example, by the fact that the probability of price changes sharply increases by days 335 and 353 of their invariability. This fact reinforces the conclusions on the presence of seasonality in price changes found in a number of foreign studies. The analysis also suggests that, in March–May 2020, growth in uncertainty caused by the coronavirus pandemic led to firms beginning to change prices more often and by a smaller magnitude. As a result, the share of price increases went up from 50.2% in March–May 2019 to 62.7% in March–May 2020. The number of days in which prices for any goods and services increased rose from 65 to 84 (out of 92 days in March–May). Thus, the results of this paper confirm that pricing behavior on the e-commerce market can vary significantly depending on economic conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>жесткость цен</kwd><kwd>денежно-кредитная политика</kwd><kwd>издержки меню</kwd><kwd>функция риска</kwd><kwd>потребительские цены.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>price rigidity</kwd><kwd>e-commerce market</kwd><kwd>menu costs</kwd><kwd>hazard function</kwd><kwd>price changes.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена в рамках выполнения научно-исследовательской работы государственного задания РАНХиГС.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Божечкова А., Гребенкина А., Евсеев А.
