Biproportion et offre dominante (A propos de l'article d'André Torre ‘Sur la signification théorique du modèle d'offre multisectoriel')

1996

One replies here to partisans of the reject of the supply-driven model in input-output analysis and especially to A. Torre (Revue Economique, 5, 44, 951-970). First of all, demand-driven hypothesis (Leontief) and supply-driven hypothesis (Ghosh) are symmetrical and incompatible, what forbidden to reject the second to the motive that it depends on the first. Secondly, the results earlier obtained for France of 1970 to 1985 from the method of the biproportionnal filter show that there is so much instability in the long term in the columns than in the rows of the flow matrix. Thirdly, the assimilation of the usage of allocation coefficients to the adoption of the supply-side model is excessive.

A Note on Qualitative Input-Output Analysis

1995

International audience; The paper discusses qualitative input—output methods. It is shown that information is lost. Because the binaiy relationship constructed by qualitative methods is not transitive, the model lacks economic consistency. Qualitative methods are tending to become more sophisticated, but some problems of economic interpretation are raised.

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…

Normalizing biproportional methods

2002

International audience; Biproportional methods are used to update matrices: the projection of a matrix Z to give it the column and row sums of another matrix is R Z S, where R and S are diagonal and secure the constraints of the problem (R and S have no signification at all because they are not identified). However, normalizing R or S generates important mathematical difficulties: it amounts to put constraints on Lagrange multipliers, non negativity (and so the existence of the solution) is not guaranteed at equilibrium or along the path to equilibrium.

Managerial Behavior in the Lab: Information Disclosure, Decision Process and Leadership Style

2019

This paper reports the results from a lab experiment in which subjects playing the manager role can implement either an efficient / inegalitarian allocation or an inefficient / egalitarian allocation of payoffs. The experiment simulates a stylized managerial context by allowing the manager to manipulate information and select the decision process and by allowing the stakeholders to retaliate against the manager given different choices in the decision process. We found that the inefficient allocation is often selected and that this choice depends on whether the employees can retaliate against the manager and on whether the manager can hide information about the payoffs. The social preference…

Dimensions et dynamique de la coordination des soins de ville : une analyse économique

2019

Cet article vise à clarifier la notion de coordination en santé, à expliciter ses différentes dimensions et à revenir sur son statut dans un processus de production de soins. Une appréhension plus fine de la coordination permet de mieux analyser le bien-fondé, les difficultés des coordinations promues par les politiques de santé. Nous nous appuyons à la fois sur des études de terrain menées auprès de réseaux, de dispositifs de télémédecine et de MSP, et sur des approches théoriques de la coordination couvrant différents courants de l’économie des organisations.

Wine - investment: a profitable alternative investment or a simple long term pleasure?

2014

International audience; The purpose of this work is twofold: - to make a first historic analysis of performance through an investment in wine by comparing its performance with those that would have been possible to obtain at the same time by providing financial term investments; - to introduce the regional diversity of performance by considering the situation in the three selected geographic areas.

The assignment of powers in an open-ended European Union

2003

Presented at CESIFO Conference “A Constitution for the EU”, February 2003; International audience; A major characteristic of the European Union is its transitional or evolving nature, in particular with regard to the assignment of powers between the two main levels of government. More precisely, under current constitutional arrangements, this evolving nature takes the form of an integration process which tends to be monotonous, that is, which can only with great difficulty be reversed. The paper is mainly devoted to the explanation of how this comes about and what effects this has on other features of the process. As a concluding remark, however, it suggests that an additional criterion for…

Horizontal competition in multilevel governmental settings

2013

28 pages; Governments situated on the same level of a multi-level governmental system compete with each other as well as with governments placed higher or lower. This paper is concerned with horizontal competition only. It discusses both competition based on the mobility of agents and competition based on comparisons of performance across jurisdictions - i.e., yardstick competition. With regard to the first kind, the focus is on the capacity of governments and voters to decide policies in spite of the mobility of agents. Some attention is also given to non-standard mechanisms in which mobility is manipulated so as to change the structure of the electorate. The paper considers two forms of h…
