In the decision rendered on February 10, 2009 in Allianz S.p.A., Assicurazioni Generali S.p.A. v. West Tankers Inc. (Case C-185/07) ("West Tankers"), the European Court of Justice ("ECJ") quashed another procedural remedy which is typical of common law countries only and deeply rooted in such countries' history: the anti-suit injunction. Under such remedy, the court issues an order, directed to one of the parties to the proceedings pending before it, not to begin or continue another proceedings before a foreign court. The lack of performing the order results in heavy sanctions ...

A Dual-Process Model of Interactivity Effects

Although interactivity is often considered to have a positive influence on persuasion, research on interactivity effects is actually very mixed. This paper argues that under certain circumstances, interactivity may either enhance or inhibit persuasion. A dual-process model of interactivity effects is proposed and tested that posits differential effects of interactivity on persuasion depending on person and situation factors. Results of an experiment that manipulated level of Web site interactivity and task involvement, and measured user ability (Internet usage experience), show that under low-involvement conditions, the mere presence of interactivity served as a peripheral cue that led to more positive attitudes regardless of ability (experience). Under high-involvement conditions, however, interactivity elicited more positive attitudes for experienced users but less positive attitudes for inexperienced users. Implications for the use of interactivity in advertising and promotions are discussed

A Dynamic Model of the Limit Order Book

pas sous affiliation hecThis paper presents a model of an order-driven market where fully strategic, symmetrically informed liquidity traders dynamically choose between limit and market orders, trading off execution price and waiting costs. In equilibrium, the bid and ask prices depend only on the numbers of buy and sell orders in the book. The model has a number of empirical predictions: (i) higher trading activity and higher trading competition cause smaller spreads and lower price impact; (ii) market orders lead to a temporary price impact larger than the permanent price impact, therefore to price overshooting; (iii) buy and sell orders can cluster away from the bid-ask spread, generating a hump-shaped order book; (iv) bid and ask prices display a comovement effect: after, e.g., a sell market order moves the bid price down, the ask price also falls, by a smaller amount, so the bid-ask spread widens; (v) when the order book is full, traders may submit quick, or fleeting, limit orders.

Analysis and Optimization of a Combined Make-to-Stock and Make-to-Order Multiproduct Manufacturing System

We consider a single-stage multiproduct manufacturing facility producing several end-products for delivery to customers with a required customer lead-time. The end-products can be split in two classes: few products with high volume demands and a large number of products with low-volume demands. In order to reduce inventory costs, it seems efficient to produce the high-volume products according to an MTS policy and the low volume products according to an MTO policy. The purpose of this paper is to analyze and compare the impact of the scheduling policy on the overall inventory costs, under customer lead-time service level constraints. We consider two policies: the classical FIFO policy and a priority policy (PR) which gives priority to low volume products over high volume products. We show that for some range of parameters, the PR rule can significantly outperform the FIFO rule. In these ranges, the service level constraints are satisfied by the PR rule with much lower inventory costs.

Behavior in the loss domain: An experiment using the probability trade-off consistency condition


Journal of Economic Psychology

Départements : GREGHEC (CNRS)

Abstract: In gambles with two or more outcomes, the two versions of prospect theory, i.e., original prospect theory and cumulative prospect theory, make use of different composition rules and therefore yield different valuations of gambles. We test these composition rules in the loss domain using the probability trade-off consistency condition. The probability trade-off consistency condition offers a convenient and efficient way to compare gambles under risk and decision makers' behavior. Experimental findings suggest that the rank dependent version of prospect theory, or cumulative prospect theory, cannot be rejected in the loss domain while original prospect theory is clearly rejected when a certainty effect is taken into account.

Belief-free equilibria in games with incomplete information

We define belief-free equilibria in two-player games with incomplete information as se- quential equilibria for which players' continuation strategies are best-replies, after every history, independently of their beliefs about the state of nature. We characterize a setof payoffs that includes all belief-free equilibrium payoffs. Conversely, any payoff in the interior of this set is a belief-free equilibrium payoff.Keywords: repeated game with incomplete information; Harsanyi doctrine; belief-free equilibria.

Causation needs more attention in strategy research. Confusion prevails around the statistical or causal nature of core relationships between resources, competitive advantage, and performance in the strategy corpus. Based on a discussion of alternative epistemological perspectives on causation, we define epistemological conditions that help to both dispel some of this confusion and to provide a basis for a counterfactual approach to causation. In particular, we argue that a counterfactual approach ' that builds on a systematic analysis of 'what-if' questions ' can advance our understanding of key causal mechanisms in strategy research. We offer two concrete methodologies ' counterfactual history and causal modeling ' as methodological solutions for causal strategy research. We show that counterfactual methods can open up new avenues for historical analysis, which has been very limited in our field, but maintain that such studies should take into account the inherent cognitive biases of retrospective constructions. We also illustrate that causal modeling provides opportunities for new conceptualizations and empirical testing of the relationships between resources and performance. In particular, resource properties can be regarded as mediating mechanisms in these causal relationships.
