In 2000s, Russian large retailers captured a large share of the market and obtained a significant market power. This change in the market organization may enhance or deteriorate social welfare. Public interest in this issue stimulated adoption by the Russian Parliament (State Duma) of the law against the concentration of trade in the hands of ...

In Russia the chain-stores gained a considerable market power. In the paper we combine a Dixit-Stiglitz industry with a
monopolistic retailer. The questions addressed are: Does the retailer always deteriorate welfare, prices and variety of goods?
Which market structure is worse: Nash or Stackelberg behavior? What should be the public policy in this area? ...

We define a general equilibrium model with heterogeneous individuals who are endowed by identical preferences, given by utility function with constant elasticity of substitution (CES), and by heterogeneous entrepreneurial skills. We find that scale effects linked to migration are tractable in the framework of the constructed model because the migration changes the market size together ...

In Russia, chain stores have achieved considerable market power. In this work, we combine a Dixit–Stiglitz industry model with a monopolistic retailer in order to address the following questions: does the retailer always impair prices, variety of goods, and ultimately welfare? Which market structure is worse: Nash or Stackelberg? What should be the public policy in this area? ...

A contract theory model is studied in which objective functions of a regulator and of two types of firms include ecological variables. It is shown that the choice of a way of functioning of the regulating mechanism (separating or pooling) depends both on political conditions (what kind of regulator defines the mechanism and the contracts) ...

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 ...

We develop a monopolistic competition model with two sectors and heterogeneous agents who self-select into entrepreneurship, depending on entrepreneurial ability. The effect of market size on the equilibrium share of entrepreneurs crucially hinges on properties of the lower-tier utility function for differentiated varieties – its elasticity of substitution and its Arrow-Pratt index of relative risk ...

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 ...

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 ...

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 ...

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 ...

This paper offers a new theory that describes the influence of uncertainty on economic fundamentals. This theory posits that uncertainty can improve social welfare. We argue that in an economy, where spending of the customers for the differentiated good correlates with larger substitutability of its varieties, the equilibrium output decreases and the prices increase when uncertainty appears. Alternatively, if such ...

This study examines the relationship between personalisation tools in the e-commerce market on the example of e-grocery and customer satisfaction, identifies the factors which can influence positive consumer experience leading to increased customer satisfaction and, as a result, increased consumer trust. The authors consider the triad “customer satisfaction — trust — customer loyalty” and propose an algorithm for the ...

На основе известной модели монополистической конкуренции Мелица с конечным числом фирм строится ряд моделей, призванных прояснить динамическое поведение оригинальной конструкции. Рассмотрены два варианта формальной динамической модели Мелица, в одном из них найдено квазистационарное состояние. Также построены модели с созданием новых фирм за счет затрат труда и продукта. Обнаружено, что в последней при некоторых условиях на ...

The paper focuses on the specifics of government regulation of higher education market in Russia. We propose a theoretical model of price competition between universities under vertical differentiation, where each university provides services in accordance with state-funded quota and sets the price for the services produced above this quota. It is shown that efficient allocation ...

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 ...

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 ...

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 ...

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 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 ...
