More firms, more competition? The case of the fourth operator in France's mobile phone market

2010

Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…

Strategies for Heading Off is Project Failure

2000

Although investment in information technology and information systems continues to increase, projects continue to fail. As a result, IS projects, particularly software projects, are perceived as high risk. By categorizing types of risk, this article helps IS professionals and all project sponsors to identify classes of risk and choose the appropriate managerial behavior to mitigate each of them.

Is the French mobile phone cartel really a cartel?

2009

International audience; France Telecom (FT), SFR and Bouygues Telecom (BT) have been fined by France's Conseil de la Concurrence (CC) for organizing a mobile phone cartel with stable market shares (one-half, one-third and one-sixth, respectively) and for directly exchanging commercial information. While not contesting the legal decision, it is argued here that the economic reasoning is flawed. (1) As the CC made much of the firms' stable market shares, we have first followed this line of reasoning by considering that the market shares are quotas under uniform costs. Even if there is a general incentive to form a monopolistic cartel, BT was too small for it to be worth its while to join it; it i…

Input-output matrices and structural analysis are applied to the analysis and forecast of consequences of offensive actions in the case of multiproduct multimarket large firms.

Les followers ont-ils vraiment de l'importance dans le modèle de Stackelberg?

2011

In this paper, we consider a T-stage linear model of Stackelberg oligopoly. First, we show geometrically and analytically that under the two conditions of linear market demand and identical constant marginal costs, the T-stage Stackelberg model reduces to a model where T oligopolies exploit residual demand sequentially. At any stage, leaders behave as if followers did not matter. Second, we study social welfare and convergence toward competitive equilibrium. Especially, we consider the velocity of convergence as the number of firms increases. The convergence is faster when reallocating firms from the most to the less populated cohort until equalizing the size of all cohorts.

The Role of External Environment in Upper Echelons Theory

2014

Upper echelons research has largely focused on the antecedents and consequences of top management teams (TMTs) from the team and firm levels of analysis. This paper reviews empirical research on TMTs with a specific emphasis on the role of the external environment. Applying institutional and industrial organization theories, a cross-level conceptual model outlining the direct, mediating, and moderating effects of the external environment on upper echelons is developed. This review distinguishes between industry and institutional levels of analysis and three types of environmental characteristics: stable, dynamic, and transformational. The paper further explains the relationships between ea…

Corporate social irresponsibility: review and conceptual boundaries

2017

PurposeThe purpose of this paper is to carry out a review of the academic literature about corporate social irresponsibility (CSIR) highlighting aspects that help us to define socially irresponsible behaviour and its relationship with socially responsible behaviour.Design/methodology/approachThrough a Boolean search of studies related to terms of irresponsibility undertaken from 1956 to October 2016, the authors develop a review of the literature focussing on the main perspectives used for defining the term of CSIR.FindingsThe paper provides a framework of three main dimensions for understanding the differences in the literature that defines CSIR: who defines irresponsible behaviour, an imp…

Biproportional Method for Analysing Interindustry Dynamics: the case of France

1990

Two elements are being presented in this paper: (1) A new and original method for analysing matrix dynamics, called the synthetical biproportional projector method (SBP), which can be used to project input–output tables and compare one with another. (2) Some results for France for the important period 1970–85. The paper starts with the observation that no systematic study of the change in the French productive structure as displayed In the input–output tables (tableaux entries-sorties in France) has ever been made. This is unfortunate, since a complete series of data is now available concerning a key period of the French economic evolution including the petroleum crisis, European integratio…

The London Stock Exchange: Strategic Corporate Governance Restructuring After Demutualization

2014

International audience; This study uses the London Stock Exchange (LSE), forced to demutualize due to major changes in its business environment, notably due to increased competition and technological advances, as field experiment to study corporate governance restructuring to adapt to new market conditions. The LSE improved its financial situation after demutualization and is an example of successful corporate governance restructuring. The LSE significantly restructured the composition of its board of directors following demutualization. The number of exchange members on the LSE board decreased after demutualization while the number of independent directors increased, pointing to a more “mo…
