When consumers concentrate their purchases at a single firm, a firm that offers more products than its rivals can gain market share for all its other products, as well. These spillovers induce firms to compete by offering a greater variety of products rather than lower prices, and a natural...

The article examines a differentiated-products duopoly model where the firms make entry decisions to two markets and then choose prices. The effects of product differentiation and entry costs are analyzed in two games: with and without price discrimination between the markets. Allowing price...

The distribution of consumer incomes is a key factor in determining the structure of a vertically differentiated industry when consumer's willingness to pay depends on his income. This paper computes the Shaked and Sutton (1982) model for a general specification of consumers' income distribution...

The development of the market of a product needs a wide knowledge of consumption and marketing practices relevant. This paper issue is to analyze the cashew nuts commercialization system in Bantè and Savalou regions in order to identify strengths and weaknesses relevant to the cashew nuts chain...

When focusing on firm’s risk-aversion in industry equilibrium, the number of firms may be either larger or smaller when comparing market equilibrium with and without price uncertainty. In this paper, we introduce risk-averse firms under cost uncertainty in a model of spatial differentiation...

Economies of scale in upstream production can lead both disintegrated downstream firms as well as its vertically integrated rival to outsource offshore for intermediate goods, even if offshore production has moderate cost disadvantage compared to in-house production of the vertically integrated...

A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

This paper develops a model of pricing and advertising in a matching environment with capacity constrained sellers and uncoordinated buyers. Sellers' search intensity attracts buyers only probabilistically through costly informative advertisement. Equilibrium prices and profit maximizing...
