Price discrimination bans for dominant firms<\/p>\n

Jan Bouckaert (Universiteit Antwerpen)
\nPaper<\/a><\/p>\n

Abstract<\/em>:
\nCompetition authorities and regulatory agencies sometimes impose pricing restrictions on firms with substantial market power — \u00ab\u00a0dominant\u00a0\u00bb firms. We analyze the welfare effects of a ban on behavior-based price discriminination in a setting where the market displays a competitive and a sheltered segment. A ban on \u00ab\u00a0higher-prices-to-sheltered-consumers\u00a0\u00bb decreases prices in the sheltered segment, relaxes competition in the competitive segment, increases the rival’s profits, and may harm the dominant firm’s profits. Our paper shows that banning \u00ab\u00a0higher-prices-to-sheltered-consumers\u00a0\u00bb increases the dominant firm’s share of the first-period market. A ban on \u00ab\u00a0lower-prices-to-rival’s-customers\u00a0\u00bb decreases prices in the competitive segment, lowers rival’s profits, and augments consumer surplus. In particular, while second-period competition is relaxed by a ban on \u00ab\u00a0lower-prices-to-rival’s-customers\u00a0\u00bb, first-period competition intensifies substantially leading to lower prices \u00ab\u00a0on-average\u00a0\u00bb over the two periods. Our findings therefore highlight that a dynamic two-period analysis may lead to opposite conclusions as compared to a static one-period analysis.<\/td>\n<\/tr>\n

Uncertain Lifetime, Redistribution and Nonlinear Pricing of Annuities<\/p>\n

presented by Marie-Louise Leroux (CORE, Universit\u00e9 Catholique de Louvain)<\/p>\n

(co-authors: Antoine Bommier (TSE) and Jean Marie Lozachmeur (TSE))Abstract<\/em>
\nThis paper studies the problem of redistribution between individuals with different survival rates. We use a continuous time model in which there are two types of individuals characterized by different survival probability path. We use a generalized life cycle utility function which can exhibit some risk aversion with respect to the length of life. We thus compare successively utilitarian allocations when individuals are risk neutral or risk averse towards the length of life. This problem is analyzed both with full infomation and asymmetric information.

The role of organisational commitment in the analysis of resistance to change : mediating or moderator effects?<\/p>\n

presentation<\/em><\/a><\/p>\n

Abstract<\/em>
\nHigh levels of resistance to change (RTC) and low levels of organisational commitment (OC) are often linked to similar actions, expressions of disorientation and organisational dissent. This study aims to examine in greater depth the relationship between RTC and OC in order to verify whether OC acts as a mediating variable (Research Model 1) or as a moderator variable (Research Model 2). To test this in the field, an empirical study was carried out among over three hundred middle managers in a service provider company undergoing a radical process of change. The hypotheses tested are placed within a research model wherein the extent to which middle managers perceive a gain or a loss as a consequence of the change process, and the extent to which they feel involved are the antecedents of RTC. From the results of the research, it can be deduced that organisational commitment has a mediating effect on RTC, while its hypothetical moderator effect does not receive any empirical confirmation. As a consequence, practical implications related to the use of HRM tools are discussed for more effective change management.

Why environmental regulation may lead to no-regret pollution abatement<\/p>\n

M. Pierre-Andr\u00e9 JOUVET
\nEconomiX, Universit\u00e9 Paris X Nanterre
\n(co-author: Thierry Br\u00e9chet, CORE, UCL)
\nPaper<\/a><\/p>\n

Empirical evidence support the existence of pollution abatement possibilities at negative costs, the so-called `no-regret options’. We provide a microeconomic rationale for the existence of such potential at the firm’s level under environmental regulation. An econometric application confirms that marginal pollution abatement cost curves with no-regret options are compatible with a standard production function, as stated in our theoretical model.<\/p>\n<\/td>\n<\/tr>\n

Le Design du Syst\u00e8me de Contr\u00f4le de Gestion : influence des sp\u00e9cificit\u00e9s de la PME<\/p>\n

Melles Sarah Santin, Nathalie Crutzen et Rima Rouhana
\nUER Management, HEC-ULg.<\/p>\n

Si l\u2019\u00e9tude du design du syst\u00e8me de contr\u00f4le de gestion constitue actuellement une des th\u00e9matiques privil\u00e9gi\u00e9es au sein de la recherche en contr\u00f4le de gestion, le contexte sp\u00e9cifique de la PME reste cependant peu envisag\u00e9. La pr\u00e9sente contribution propose, dans un premier temps, une revue des \u00e9tudes consacr\u00e9es aux crit\u00e8res permettant de d\u00e9finir le syst\u00e8me de contr\u00f4le de gestion d\u2019une entreprise et aux sp\u00e9cificit\u00e9s que manifestent les PME \u00e0 cet \u00e9gard. Dans un second temps, elle propose et explore, au d\u00e9part de l\u2019analyse de sept \u00e9tudes de cas, un mod\u00e8le, synth\u00e9tique, contingent et repr\u00e9sentatif des crit\u00e8res pertinents, permettant, d\u2019une part, de caract\u00e9riser le design du syst\u00e8me de contr\u00f4le de gestion en contexte PME et, d\u2019autre part, de comprendre la mani\u00e8re dont il se structure et \u00e9volue dans une qu\u00eate constante de stabilit\u00e9 adaptative.<\/td>\n<\/tr>\n

City Branding: A Brand Concept Map Analysis of a university town
\n<\/span>How is a large university town as Li\u00e8ge perceived by students ?<\/span><\/p>\n

Melle C\u00e9line Brandt
\nUER Management, HEC-ULg.<\/p>\n

We use Brand Concept Maps (BCM) as well as the Zaltman Metaphor Elicitation Technique (ZMET) to determine this perception. First, we explain what the important attributes for a university town are from the students\u2019 point of view. Then, we develop a Brand Concept Map for Li\u00e8ge as a university town. Importance-performance measures allow us to demonstrate the convergent validity, while the split-half reliability test shows the validity of our results. Finally we analyze the divergent perceptions of local and foreign students. Mainly, the goal is to validate the BCM method in the area of city branding and identify how Li\u00e8ge is perceived by local and foreign students.<\/span><\/td>\n<\/tr>\n

Faut-il br\u00fbler la flexicurit\u00e9 ?<\/span>
\nLes conditions d\u2019un compromis \u00e9conomiquement et socialement responsable<\/p>\n

Mme Virginie Xhauflair
\nLENTIC, HEC-ULg.<\/p>\n

Le terme Flexicurit\u00e9 est d\u00e9sormais pass\u00e9 dans le langage courant. S\u2019il suscite l\u2019engouement d\u2019un certain nombre d\u2019acteurs, il engendre \u00e9galement de nombreuses controverses, portant essentiellement sur l\u2019opportunit\u00e9 de r\u00e9former les march\u00e9s du travail en fonction de ce \u00ab mod\u00e8le \u00bb, et sur sa transf\u00e9rabilit\u00e9.<\/p>\n

Nous entendons contribuer \u00e0 ce d\u00e9bat en privil\u00e9giant une approche pragmatique, centr\u00e9e sur l\u2019analyse des pratiques effectives mises en \u0153uvre au niveau des entreprises et des territoires (dispositifs de mutualisation de personnel, portage salarial, skill pooling, plate-forme RH, etc.).<\/p>\n

Cette r\u00e9flexion participative nous a permis de cerner un certain nombre de conditions de succ\u00e8s des pratiques de conciliation de la flexibilit\u00e9 et de la s\u00e9curit\u00e9, et de d\u00e9gager diverses pistes d\u2019actions concr\u00e8tes \u00e0 destination de tout acteur du march\u00e9 du travail d\u00e9sireux de s\u2019engager dans une telle dynamique.<\/p>\n

\nGEMO-ESDES (Universit\u00e9 Catholique de Lyon)<\/p>\n

L\u2019analyse dominante de la notion de RSE qui prend appui sur la Th\u00e9orie des parties prenantes (TPP) laisse dans un angle mort des faits pourtant majeurs pour en saisir la port\u00e9e. Cet article montre que ces insuffisances d\u00e9coulent du fait que la TPP ne constitue pas une th\u00e9orie de la firme \u00ab compl\u00e8te \u00bb. La r\u00e9duction de ces angles morts invite \u00e0 comprendre la RSE comme une \u00e9volution institutionnelle qui participerait du passage d\u2019une gouvernance d\u2019entreprise \u00e0 une gouvernance de r\u00e9seau.<\/p>\n

Geometry of cutting plane generation in integer programming<\/strong><\/em><\/p>\n

M. Quentin Louveaux
\nCharg\u00e9 de cours, Mont\u00e9fiore (FSA – ULg).<\/p>\n

Abstract<\/em>:
\nAfter a brief overview of some common applications of integer programming, we review the most current method for solving integer programs, i.e. the branch-and-cut. We then discuss a geometric approach to the generation of cutting planes. In particular we focus on the generation of cutting planes from one and two rows of a simplex tableau. Our model consists, from two rows of the simplex tableau, in keeping two integer variables (relaxing nonnegativity) and relaxing the integrality of the remaining variables (keeping nonnegativity). The main result is that every facet of a basic two row-problem can be found from three or four variables. From the geometric point of view, every facet is either a triangle or a quadrilateral.
