We consider standard monopolistic competition models in the spirit of Dixit
and Stiglitz or Melitz with aggregate consumer's preferences defined by two well known classes of utility functions – the implicitly defined Kimball utility function
and the variable elasticity of substitution utility function. These two classes gene ralize classical constant elasticity of substitution utility function and overcome its
lack of ...

The paper studies a market of horizontally differentiated good under increasing return to scale and exogenous number of firms. Three concepts of equilibria are compared: Cournot, Bertrand and monopolistic competition. Under fairly general assumptions on consumer’s preferences, it is shown that Lerner index is the highest in Cournot case, monopolistic competition provides the lowest one ...

Standard measures of competitive toughness fail to capture the fact that, as consumers optimize intertemporally, firms operating today compete with (yet non-existent) businesses which will be started tomorrow. We develop a two-tier CES model of dynamic monopolistic competition in which the impact of product differentiation on the market outcome depends crucially on the elasticity of ...

We develop a two-factor, two-sector trade model of monopolistic competition with variable elasticity of sub- stitution. Firms' prots and sizes 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 manu- factured good, although both rm ...

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 ...

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 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, ...

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 ...

We consider a monopolistic competition model with endogenous choice of technology in the closed economy case. The aim is to make comparative statistics of equilibrium and social optimal solutions with respect to "technological innovation"; parameter which influences on costs. Key findings: with the growth of innovation and investment in the production increase; behavior of the ...

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 ...

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 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 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 ...

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 ...

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? ...

This paper studies how heterogeneous individuals, that differ by entrepreneurial skills
and productivity as a worker, endogenously choose their occupation (workers vs.
entrepreneurs) based on expected income comparison (wages vs. profits). Each entrepreneur runs a
firm that produces a single variety of a horizontally differentiated good under monopolistic
competition. We show that the cutoff for occupational selection between workers ...
