We consider a model of monopolistic competition, which includes in addition to a love of variety,love for the product quality. We proposed utility function for consumers possessing the properties the love of variety and love for the product quality. States of equilibrium in the long and short term are considered.

In this paper, we consider a model of monopolistic competition with volume of product quality in the task of economic growth. For this purpose, a model of consumers has been used, in the utility function of which, in addition to the love of diversity, love of product quality is included. For this model, the Ramsey ...

We propose a general model of monopolistic competition which encompasses existing models while being flexible enough to take into account new demand and competition features. Even though preferences need not be additive and/or homothetic, the market outcome is still driven by the sole variable elasticity of substitution. We impose elementary conditions on this function to ...

We propose a model of monopolistic competition with additive preferences and variable marginal costs. Using the concept of "relative love for variety," we provide a full characterization of the free-entry equilibrium. When the relative love for variety increases with individual consumption, the market generates pro-competitive effects. When it decreases, the market mimics anti-competitive behavior. The ...

We develop a simple partial-equilibrium model of endogenous city structure formation. No
production externalities are at work, the only two forces shaping the spatial configurations of
the city being love for variety (on the consumer side) and seeking for a better access to the market
(on the firm side). We show that, unlike in existing models of a ...

Based on the well-known model of monopolistic competition by Melitz with a finite number of firms, we built a number of dynamic models, designed to clarify the dynamic behavior of the original construction. Two variants of the formal Melitz dynamic model are presented, with the quasi-steady state found in one of them. Also, the models ...

There is strong evidence suggesting that different income groups consume different bundles of goods. Hence, trade liberalization can affect welfare inequality via changes in the relative prices of goods consumed by different income groups (the price effect). In this paper, I develop a framework that enables us to explore the role of the price effect ...

The article deals with the theory of monopolistic competition under demand uncertainty. The authors consider the economy with labor immobility consisting of the high-tech sector with monopolistic competition and the standard sector with perfect competition. Preferences between sectors are specified by the Cobb – Douglas production function. It is assumed that companies make output
decisions under ...

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 consider a general equilibrium model in a multisector economy with 𝑛 high-tech sectors where singleproduct firms compete monopolistically producing a differentiated good. Homogeneous sector is characterized by perfect competition. Workers attempt to find a job in high-tech sectors because of higher wages. However, it is possible for them to remain unemployed. Wages of employees ...

We derive a simple necessary and sufficient condition on preferences for the market outcome to be socially optimal under monopolistic competition with input-output (IO) linkages. Preferences that satisfy this condition are typically non-CES and display pro-competitive effects, although they converge to the CES when IO linkages become negligibly weak. We show that the equilibrium with ...

We develop a two-factor, two-sector trade model of monopolistic competition with variable elasticity of substitution. Firm profit and firm size may increase or decrease with market integration depending on the degree of asymmetry between countries. The country in which capital is relatively abundant is a net exporter of the manufactured good, while both firms' size ...

This paper is addressed to explanation of differentiation of economics in structure of labor market and income distribution. In order to this aim the author develops a model of endogenous formation of entrepreneurship in economics with heterogeneous agents. The nature of heterogeneity is non-trivial distribution of entrepreneurial abilities across individuals. The impact of form and ...

С начала XXI века Россия и другие развивающиеся рынки бывшего СССР демонстрируют бурный рост крупных торговых сетей в потребительском секторе. Трейдеры захватили большую долю рынка и получили значительную рыночную силу. Это изменение рыночной организации может привести к негативным последствиям для общественного благосостояния, ассортимента благ и инфляции. Общественный интерес к этому вопросу привел к дебатам в ...

We develop a general equilibrium model of monopolistic competition with a traded and a nontraded sector. Using a broad class of homothetic preferences—that generate variable markups, display a simple behavior of their elasticity of substitution, and nest the ces as a limiting case— we show that trade liberalization: (i) reduces domestic markups and increases imported ...

We provide a selective survey of what has been accomplished under the heading of monopolistic competition in industrial organization and other economic fields. Among other things, we argue that monopolistic competition is a market structure in its own right, which encompasses a much broader set-up than the celebrated constant elasticity of substitution (CES) model. Although ...

We present a general equilibrium model of monopolistic competition featuring pro-competitive effects and a competitive limit, and investigate the impact of trade on welfare and efficiency. Contrary to the constant elasticity case, in which all gains from trade are due to product diversity, our model allows for a welfare decomposition between gains from product diversity ...

Inspired by advances in general equilibrium modelling with monopolistic competition were-consider the problem of the choice of firms under uncertainty, explore it in the framework of general equilibrium modelling, and develop a theory of monopolistic competition under demand uncertainty. We distinguish between two cases of uncertainty. In the first case the uncertainty disappears by the ...

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 ...

A model of monopolistic competition for a closed economy, consisting of the traditional sector and the industrial production sector, which includes multi-product companies, is built. The consumption sector consists of heterogeneous consumers with a two-level Cobb-Douglas utility function and a generalized CES utility function built into it. The generalized CES utility function, unlike the standard ...

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 ...
