В статье исследуется поведение гетерогенных (неоднородных) фирм, выпускающих дифференцированные товары в условиях монополистической конкуренции. Показана важность неоднородности фирм в достижении равновесия и общественного оптимума. В статье дается характеристика различных аспектов оценки моделей равновесия на рынке монополистической конкуренции, а также оптимального общественного результата (Парето-оптимума). Основная цель работы - моделирование рыночного равновесия при переменной эластичности спроса и эндогенной неоднородности фирм, что позволит найти оптимум между количеством и разнообразием благ на рынке. Представленная модель позволяет ответить на нормативные вопросы: о выборе между количеством и разнообразием продукции; о достаточности/избыточности предлагаемых продуктов или их возможном дефиците; об эффективности технологий, используемых фирмами при производстве продуктов; об оптимальном размере конкурентно монопольных отраслей по отношению к остальной экономике; о противодействии искажениям в работе рыночного механизма, свойственным монополистически конкурентному рынку. В заключении представлены основные выводы, имеющие практическое значение для целей разработки государственной (налоговой) политики.

The article investigates the behavior of heterogeneous firms associated with the production of differentiated goods under conditions of monopolistic competition. Shows the importance of heterogeneous firms in achieving equilibrium and social optimum. Great attention is paid to the consideration of variable demand elasticity and endogenous heterogeneous firms. In the article, the various aspects of the evaluation of models of market equilibrium monopolistic competition, and social optimum (Pareto-optimum). The research is carried out through the consideration of issues such as: the number of represented products; the adequacy of our products and their possible deficit; efficiency of technology choice in the production of products; the optimal size of a monopolistic competitive industries relative to the rest of the economy. In the conclusion summarizes the key findings.
