The purpose of this article is to present a novel method to approximately solve the Multiple-Scenario Max-Min Knapsack Problem (MSM2KP). This problem models many real world situations, e.g. when for many scenarios noted $\pi \in \mathcal P=\{1,\ldots,P\}$, the aim is to identify the one offering...

The purpose of this paper is to introduce the area of Green Logistics and to describe some of the problems that arise in this subject which can be formulated as combinatorial optimization problems. The paper particularly considers the topics of reverse logistics, waste management and vehicle...

The basic Vehicle Routing and Scheduling Problem (VRSP) is described followed by an outline of solution approaches. Different variations of the basic VRSP are examined that involve the consideration of additional constraints or other changes in the structure of the appropriate model. An...

Pensions reforms have been accelerating in Europe since the 1990s and the beginning of the 2000s : a common trend consists of strengthening the link between the individual contribution period and the level of pension. In a first part of the paper, we show that this common trend takes place...

I examine in detail the motives of bilateral aid allocation decisions, as they are revealed by data on bilateral aid commitments. I identify both self-interest and recipient needs and merits motives in aid allocation. Self-interest motives are related to economic and political ties between...

Most studies on the green tax reform issue point out that environmental taxes exacerbate pre-existing tax distortions, thereby increasing the welfare costs associated with the overall tax code. As a result, the optimal environmental tax should lie below the Pigovian level (or marginal social...

In this paper, we study the on-line version of the bin-packing problem. We analyze the approximation behaviour of an on-line bin-packing algorithm under an approximation criterion called differential ratio. We are interested in two types of results : the differential competitivity ratio...

The aim of this paper is to scope the different institutional possibilities offered to the Europeans infrastructure managers into obtaining the most efficient cooperation between them and evaluate the possible effects of the European commission policy on this topic. The goal of this cooperation...

This paper investigates the relative importance of different types of news in driving significant stock price changes of firms in the defense industry. We implement a systematic event study with a sample of the 58 largest publicly listed companies in the defense industry, over the time period...

We introduce a two-period general equilibrium model with uncertainty and incomplete financial markets, where default is allowed and agents face in case they do default an utility penalty, which is their own private information. In this setting, if agents have heterogeneous characteristics they...
