CPI vsPPI: A Cointegration Analysis Allowing for Number of Breaks

The Empirical economics letters. 2017. Vol. 16. No. 2. P. 95–106.
Alatas S.

This study examinesthe relationship producer prices andconsumer prices in Turkey and econometrically investigatescointegration relationship and causality for Turkeyby employing monthly data for the period January, 1986-November, 2015. Even though consumer and producer prices are so sensitive to economic shocks and regime shifts, studies in existing literature analyzing cointegration relationshipbetween producer prices and consumer prices data do not take into account structural breaks. This paper contributes to this point and tries to close this gap for Turkey. We foundthat structural breaks havesignificantimpact on relationship between consumer prices and producer prices and some change might occur when we take into account structural breaks in data.

Игры на сетях с линейным наилучшим ответом: модели и методы управления
Petrov I., Автоматика и телемеханика 2026 № 6 С. 82–118
Системам связанных агентов и сетевому управлению посвящено большое число отечественных и зарубежных исследований. Исторически, наибольший интерес в теории управления возникал к усредняющим системам и, в частности, к задаче консенсуса. Однако сетевое взаимодействие может характеризоваться более специфическими функциями, отражающими зависимость от действий соседей по сети, что особенно явно проявляется в моделях стратегического взаимодействия на сети, которое ...

Социально-экономическая география зарубежных стран: материалы к курсу. Часть 1. Основные концепции региональной наук
Zamyatina N., Rusakov D., Evgeny V., Издательские решения, 2022.
Десятилетиями социально‑экономическая география зарубежных стран представляла собой по большей части сбор данных о размещении отраслей хозяйства — с довольно слабой концептуальной базой соответствующих процессов. Это не удивительно, если вспомнить, что отечественная экономическая география занималась размещением хозяйства в условиях социализма. Сама возможность применения отечественных концепций к «зарубежным капиталистическим странам» вызывала жаркие споры в профессиональной среде отечественных экономгеографов — многие представители старшего поколения помнят, как ломались копья в дискуссии о том, например, возможны ли территориально‑производственные комплексы в условиях капитализма. Между тем параллельно в «зарубежных капиталистических странах» формировались целые группы научных школ в сфере изучения размещения хозяйства и регионального развития, зачастую на стыке региональной экономики и собственно экономической географии (за рубежом всё чаще используется обобщающее наименование — региональная наука, или региональные исследования: regional science/regional studies). Анализируя экономико‑географические проблемы зарубежных стран, современные исследователи используют широкий набор понятий, сложившихся в последние примерно три десятилетия, и пока ещё, к сожалению, довольно слабо знакомых отечественным географам (от «перетоков знания» до «тройной спирали»). Часть зарубежных разработок — вроде теории кластерного развития — вошли и в отечественную науку; однако нередко зарубежные концепции используются в несколько суженной и искажённой трактовке (как правило, в силу инерции парадигм мышления, чуждых используемым концепциям). Зачастую исследователи, наоборот, не видят потенциал применения тех или иных концепций на нетрадиционном материале. Институт регионального консалтинга (ИРК), в котором начинали свой путь в профессиональную аналитику уже десятки выпускников кафедры социально‑экономической географии зарубежных стран географического факультета МГУ, принял решение способствовать овладению актуальными концепциями в сфере региональной науки как студентами указанной кафедры, так и всеми российскими исследователями в сфере экономической географии и регионального развития. При финансовой и организационной поддержке ИРК уже подготовлена серия учебных пособий «Институт регионального консалтинга — студентам». Ранее вышедшее пособие «Эволюционное страноведение: материалы к курсу. Часть 1. Смета траектории регионального и странового развития: разбор примеров» призвано продемонстрировать спектр возможностей применения актуальных концепций региональной науки в страноведении и анализе развития отдельных регионов России и зарубежных стран (в 2022 году подготовлено второе издание пособия, исправленное и дополненное). Для нового пособия по социально‑экономической географии зарубежных стран отобраны ключевые (на взгляд редактора) направления, необходимые современному специалисту для понимания развития мировой региональной науки. В абсолютном большинстве это концепции актуальной экономической географии; кроме того, добавлены экономические понятия, без знания которых затруднено понимание мейнстрима региональной науки (так, например, тема убывающей и возрастающей отдачи является ключевой для понимания направления так называемой «новой экономической географии» в экономике), а также системы популярных прикладных мер в региональном развитии («новая промышленная политика», понятие «зависимости от колеи» и др.). Разумеется, это не исчерпывающий спектр концепций и подходов экономической географии (не говоря уже о том, что в пособии совсем не затронуты концепции социальной и других направлений общественной географии); работа над подготовкой новых материалов продолжается. Появлению пособия в немалой степени поспособствовал труд магистранта кафедры социально‑экономической географии зарубежных стран географического факультета МГУ имени М. В. Ломоносова Фёдора Чернецкого в рамках прохождения производственной практики в Институте регионального консалтинга. Авторами разделов стали студенты указанной кафедры. В ходе практической части курса «Социально‑экономическая география зарубежных стран» они выполняли задание не только тщательно описывать методологический контекст и суть той или иной концепции, но и продемонстрировать её работу на конкретном примере — российском или зарубежном. Разработка задания и общая редакция проведена Надеждой Замятиной, их преподавателем и одновременно заместителем директора Института регионального консалтинга.
