It is usually believed that higher competition, implying more active firms, benefits consumers. We show that this may not be the case in an industry with asymmetric cost firms. A rise in the number of more cost inefficient firms makes the consumers worse-off in the presence of a welfare...

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...

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...

We try to determine whether capacity expansion timing in oligopoly among incumbents can be considered mobility deterring. We study the United Kingdom ´s petroleum refining industry between 1948 and 1998. Using tobit models, evidence is conclusive about accommodation among incumbents. We infer...

We try to get a handle on whether capacity expansion timing patterns in oligopoly among incumbents are followed. We study the United Kingdom ´s petroleum refining industry between 1948 and 1998. Using fixed-effects logit models, we find that U.K.´s refiners have not followed any definite...

Based on the simple model of the deposit the methodology of finding the optimal solution for bilateral monopoly (BM) of lignite mine and power plant is shown taking into account pit optimisation. It is proposed to treat lignite price negotiation as a kind of game. In the first stage...

We examine how Sutton’s “bounds” approach works in a small country where industries have relatively high export and import intensities. Import competition is used as an indicator for the degree of competition in the low sunk cost industries. The bounds are estimated as stochastic...

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...
