Players are assumed to be reflexive: each player conjectures about the strategies of all other players. As a result, the subsets of players with different Stackelberg leadership levels are formed in this game (a game with multilevel leadership). The reflexion of players is formalized by conjectural variations, i.e., players’ expectations regarding the impact of their actions on the counterparty’s action. The problem of controlling the strategy of one player (the controlled player) by the other (n −1) players (the Principal) is investigated, and an optimal Nash equilibrium is established in terms of the Principal’s utility criterion. A hierarchical game model of players’ interactions is proposed, and the dependence of the maximum of the Principal’s utility function on the vector of the sums of conjectural variations (SCV) of all players is found within this model. The dependence is used to calculate the controlled player’s SCV value optimizing the Principal’s utility function. An informational control method is developed, enabling the Principal to induce the controlled player to choose the reaction function optimal from the former’s standpoint.</p></abstract><trans-abstract xml:lang="ru"><p>Рассматривается игра олигополии n лиц при объемной конкуренции для случая функций спроса и издержек общего вида. Игроки считаются рефлексирующими, т.е. выдвигают предположения о стратегиях других игроков, в результате чего в игре образуются подмножества игроков с различными уровнями лидерства по Штакельбергу, т.е. рассматривается игра с многоуровневым лидерством. Рефлексия игроков формализована в виде предположительных вариаций, т.е. предположений игроков о влиянии их действий на действие контрагента. Исследуется проблема управления стратегией одного игрока (управляемого игрока) со стороны остальных n − 1 игроков (Центра), в результате чего устанавливается равновесие Нэша, оптимальное по функциям полезности игроков Центра. Предложена модель взаимодействий игроков в виде иерархической игры, для которой найдена зависимость максимума функции полезности Центра от вектора сумм предположительных вариаций (СПВ) всех игроков, позволяющая вычислить значение СПВуправляемого игрока, оптимизирующее функцию полезности Центра. Разработан способ информационного управления действиями игрока, осуществляемого Центром путем управляющего воздействия, побуждающего игрока выбрать оптимальную для Центра функцию реакции.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>олигополия</kwd><kwd>предположительная вариация</kwd><kwd>лидерство по Штакельбергу</kwd><kwd>иерархическая игра</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oligopoly</kwd><kwd>conjectural variation</kwd><kwd>Stackelberg leadership</kwd><kwd>hierarchical game</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Anderson, S.P., Erkal, N., and Piccinin, D., Aggregative Games and Oligopoly Theory: Short-Run and Long-Run Analysis, RAND J.
