Verbus V. A., Kichko S., Osharin A.
The paper considers a model of monopolistic competition for the case of heterogeneous consumers, who differ from other with respect to product quality. To do this, a model of consumers, which in addition to the love of variety included a love of quality products. The industrial sector, in turn, consists of firms that produce a variety of differentiated products of different quality, focused on a certain type of buyer, i.e. the case of multi-product firms is considered. The function of supply and demand for the quality of goods is obtained, the equilibrium states in the long and short term are considered for two different situations when firms have market power in determining the quality of products and when they do not possess it.

The problem of the low quality of goods and services purchased for public needs has sharply exacerbated in a pandemic. Although the Russian state has successfully coped with the challenges of the pandemic, the problem of ensuring the quality of public procurement has not lost its relevance. The study systematizes the factors that negatively affect ...

The paper develops a two-country monopolistic competition model of trade featuring country-specifc consumer tastes. The accounting for heterogeneity in tastes is achieved by assuming diferent elasticities of substitution in the CES utility function for diferent country consumers. The proposed framework extends the canonical Krugman’s approach by revealing new efects regarding markups response to consumer heterogeneity ...

The paper builds a two-sector monopolistic competition model featuring multi-product firms and heterogeneous consumers endowed with a Cobb–Douglas utility nesting a generalized CES function. In contrast to the standard CES, the generalized CES function includes both the love of variety and the love for product quality, which makes it possible to distinguish consumers differing in their ...

The paper considers a two-sector two-country trade model of monopolistic competition featuring the heterogeneity of consumer preferences and incomes within and across countries. The incorporation of heterogeneity into a monopolistic competition setting is achieved by assuming a nested Cobb–Douglas and CES utility function exhibiting both country and sector-specific consumer tastes and expenditure shares on manufacturing ...

В статье осуществлена систематизация механизмов импортозамещения в российской системе государственных и муниципальных закупок и оценка их влияния на качество закупаемой продукции. Анализ факторов, связанных со снижением качества продукции при осуществлении закупок для государственных и муниципальных нужд, позволил сделать вывод о важности соблюдения баланса между задачей поддержки отечественных производителей и необходимостью приобретения продукции надлежащего качества. ...

The paper considers a two-country trade model of monopolistic competition featuring the heterogeneity of consumer preferences both within and across countries. The incorporation of heterogeneity into a traditional monopolistic competition setting is achieved by assuming different elasticities of substitution in the CES utility function for different consumers. The proposed setup expands on the traditional model ...

The present paper extends the traditional Dixit and Stiglitz set-up by introducing consumers’ workers’ heterogeneity into a general equilibrium model of monopolistic competition. The model obtains a closed-form solution for a symmetric equilibrium and shows how the market outcome depends on the joint distribution of consumers’/workers’ taste and labor productivities. In contrast to the traditional ...

We develop a model of monopolistic competition that accounts for consumers' heterogeneity in both incomes and preferences. This model makes it possible to study the implications of income redistribution on the toughness of competition. We show how the market outcome depends on the joint distribution of consumers' tastes and incomes and obtain a closed-form solution ...

В статье построена модель монополистической конкуренции с многопродуктовыми фирмами, невыпуклыми издержками и переменной эластичностью замещения. Изучается зависимость отраслевой концентрации фирм от размера рынка. Основным результатом является полная характеризация асимптотического поведения равновесного числа фирм и уровня концентрации при неограниченном росте размера рынка. Показано, что взаимодействие экономии от масштаба и экономии от охвата является важным фактором эмпирически ...

The paper develops a one-sector model of monopolistic competition with heterogeneous consumers, which preferences depend upon their personal income. The model is used for the analysis of the mark-ups dependence on the inequality of consumers’ income distribution and average wage. The paper shows that mark-ups can ambiguously depend upon income inequality at fixed average income, ...

The paper investigates distributional effects and market structure in a one-sector model of monopolistic competition with heterogeneous consumers. By using the CES utility function depending on consumer’s personal income the paper shows how the equilibrium prices, firm size and number of firms depend upon income distribution and intensity of competition. The proposed model extends the ...
