Agreement and disagreement between expectations and realizations
1990
The objective of the paper is to measure the intensity of the relation between expectations and realizations for strategic variables of firms, such as production, demand or prices. An anticipation error reveals a disagreement which can be associated with the rational expectations hypothesis. The agreement coefficient between classifications, given by COHEN (1968) and LIGHT (1971) and calculated from a probability matrix, is used to define a direct measure of the disagreement between classifications. Comparison of the coefficients is used to test the rational expectations hypothesis.The coefficients are applied to business survey data of INSEE for France between 1974 and 1986.
Recursive estimators 1
1991
In this paper, we present first the recursive estimation of parameters of linear regression models and we show the link between a matrix of projection and a matrix of gain. Two cases are examined : constant parameters and parameters changing over time. In the second part the recursion formulae for the two stage least squares are given.
Des capacités de choix aux probabilités de choix (un théorème de conversion)
1992
Une partie importante de la théorie des choix discrets concerne les développements du modèle de Luce 1959]. Cette place privilégiée provient sans nul doute de l’extrême élégance de PAxiome du Choix qui permet d’une part, d’introduire une sorte de rationalité imparfaite du comportement en autorisant la construction de probabilités de choix et d’autre part, de décrire un processus de choix qui semble raisonnablement réaliste : en effet, il est suggéré que l’agent faisant face à un ensemble fini d’actions, choisit dans un premier temps un sous-ensemble, puis finalement, à l ’intérieur de ce sous-ensemble, une action. Il existe de nombreuses versions de ce modèle ( Yellot [1977], Strauss [1980]…
La combinaison de prévisions multiples en présence d'objectifs multiples
1989
L'idée de combiner plusieurs prédicteurs pour générer des prévisions combinées plus fiables semble ne dater que de 1969, date de la publication de l'article de Bâtes et Granger (1969). Depuis lors on a constaté un foisonnement de publications tant théoriques qu'empiriques dans ce domaine et l'utilité pratique de la combinaison de prévisions individuelles y a été amplement démontrée.

Brand social representations: strategic perspectives for a fitness club
2009
International audience; The aim of this study was to identify an accurate tool to enable fitness club managers to discover those opinions or stereotypes which represent obstacles to joining their organisations. Starting with brand image, the analysis then considered social representations as relevant constructs for apprehending these opinions or prejudices. The use of a word association task and the model of basic cognitive schemes (Rouquette, 1990; 1994) provided access to the salient elements of the social representations of a particular sport brand and the way they are structured. The procedure combining these two stages represented a diagnostic tool for identifying the attractive and un…
Using uncertain preferential information from stakeholders to assess the acceptability of alternative forest management plans
2017
In forest management planning, participatory planning processes are often encouraged as a means to acquire relevant information and to enhance the stakeholders' acceptability of alternative plans. This requires the aggregation of the stakeholders' preferences that can be done in a wide variety of manners. The aggregation process strives to reduce the information into a single set of preferences that simplifies the information and allows for the use of discrete decision support tools. Depending on how the preferences are aggregated, a wide range of plan rankings can emerge. Although this range of ranking complicates the issue of plan selection, it does highlight the uncertainty involved in a…
Impact of supplier-specific investments in inter-organisational information systems on strategic electronic coordination: the moderation effect of bu…
2018
Abstract This paper examines the factors which influence sharing of the strategic information (in other words, electronic coordination) in a buyer–supplier dyad. The antecedents of this coordination are examined rather well in the transaction cost economics (TCE) theory and resource-dependency theory (RDT), while the supply chain management perspective is contemplated. The mentioned frameworks are used in the analysis. However, the research focus is narrowed down to the exploration of the antecedents of information exchange conducted via inter-organisational information systems (IOS). The empirical analysis is based on 198 observations of Norwegian companies operating in different types of …
