Départements : Economie et Sciences de la décision, GREGHEC (CNRS)


The paper discusses the sense in which the changes undergone by normative economics in the 20th century can be said to be progressive. A simple criterion is proposed to decide whether a sequence of normative theories is progressive. This criterion is put to use on the historical transition from the new welfare economics to social choice theory. The paper reconstructs this classic case, and eventually concludes that the latter theory was progressive compared with the former. It also briefly comments on the recent developments in normative economics and their connection with the previous two stages

Why do managers choose one sales compensation form rather than another? Theoretical answers typically focus on the type of plans managers should design, not on the factors that managers actually consider. Managers from various national origins pursue and weigh objectives through experience in a way that theoretical models may not capture. Incorporating conceptualizations from a wide range of disciplines, we specify a model examining the influence of cultural factors on sales compensation decisions of managers (incentive vs. fixed pay and parity vs. equity allocation). The model, tested with data collected from bank managers across six European countries, illustrates the importance of considering national culture when designing sales force compensation policies applied across multiple countries. We also find evidence that most European bank managers accept incentive pay to motivate salespeople but, perhaps paradoxically, overwhelmingly reject equity allocations to achieve control and parity. We discuss the implications of our findings for research on international governance systems and the diffusion of sales force management practices Keywords: Distributive justice; Compensation; Performance pay; Sales force management; National culture

A Note on Risk Aversion and Herd Behavior in Financial Markets

J. Decamps, S. LOVO

Geneva Papers on Risk and Insurance Theory

We show that differences in market participants risk aversion can generate herd behavior in stock markets where assets are traded sequentially. This in turn prevents learning of market's fundamentals. These results are obtained without introducing multidimensional uncertainty or transaction cost

Adoption and appropriation: towards a new theoretical framework. An exploratory research on mobile technologies in French companies

Départements : Management et Ressources Humaines, GREGHEC (CNRS)


L'objectif de cette recherche est de proposer un modèle alternatif qui dépasse les approches classiques de l'adoption et de l'appropriation. En effet, les approches théoriques de l'appropriation ignorent souvent la question de l'adoption des technologies par les individus. Or, les technologies mobiles sont utilisées dans la sphère privée et les individus possèdent souvent une expérience antérieure à leur utilisation dans le cadre professionnel. Par conséquent l'analyse de l'adoption et de l'appropriation au sein des organisations devrait intégrer l'analyse de l'adoption au niveau individuel. Cette recherche tente d'identifier dans une perspective exploratoire, au travers de 76 entretiens semi-directifs centrés auprès de managers dans huit entreprises françaises. L'analyse empirique met en évidence une influence certaine des logiques d'adoption individuelles sur les différentes formes d'appropriation organisationnelle. Un modèle théorique combinant l'adoption et l'appropriation est proposé en conclusion. MOTS CLEAdoption, Appropriation, Technologies mobiles, Téléphone mobile, Ordinateur portable.

Ascending auctions for multiple objects: the case for the Japanese design

We consider two ascending auctions for multiple objects, namely, an English and a Japanese auction, and derive a perfect Bayesian equilibrium of the Japanese auction by exploiting its strategic equivalence with the survival auction, which consists of a finite sequence of sealed-bid auctions. Thus an equilibrium of a continuous time game is derived by means of backward induction in finitely many steps. We then show that all equilibria of the Japanese auction induce equilibria of the English auction, but that many collusive or signaling equilibria of the English auction do not have a counterpart in the Japanese auction

Bid Ask Price Competition with Asymmetric Information Between Market Makers

R. Calcagno, S. LOVO

Review of Economic Studies

avril 2006, vol. 73, n°2, pp.329-355

Départements : Finance, GREGHEC (CNRS)


This paper studies the effect of asymmetric information on the price formation process in a quote-driven market. One market maker receives private information on the value of the quoted asset, and repeatedly competes with market makers who are uninformed. We show that despite the fact that the informed market maker's quotes are public, the market is never strong-form efficient with certainty until the last stage. We characterize a reputational equilibrium in which the informed market-maker influences and possibly misleads the uninformed market makers' beliefs. At this equilibrium, a price leadership effect arises, the informed market maker's expected payoff is positive and the rate of price discovery increases in the last stages of trade

In this article, we use Transaction Cost Economics (TCE) and the Resource-Based View (RBV) of the firm to study outsourcing agreements. We develop an original approach of contract complexity and analyse the links among exchange hazards (i.e. specificity and environmental uncertainty), the contractual aspects of outsourcing (control, incentives, penalties, price and flexibility clauses) and the level of ex post transaction costs. Both contract complexity and ex post transaction costs are operationalized and measured. Our empirical research analyses 82 outsourcing contracts. This article uses three different dimensions (proximity to the core business, switching costs and adaptation costs) to assess the strategic importance of an outsourced activity. Our findings extend TCE's validity for the outsourcing of activities with a strategic value. Finally, this study offers an indirect measurement of ex post transaction costs. In short, to restrict vendor opportunism, contracts must contain incentives and penalties, as well as pricing and monitoring clauses
