This policy contribution provides up-to-date evidence of the strong heterogeneity in the relationships between the five biggest EU economies with the Southern Mediterranean Countries (SMCs). Algeria, Morocco and Tunisia are still strongly tied to France, Italy and Spain, in terms of...

This policy contribution provides up-to-date evidence of the strong heterogeneity in the relationships between the five biggest EU economies with the Southern Mediterranean Countries (SMCs). Algeria, Morocco and Tunisia are still strongly tied to France, Italy and Spain, in terms of investments,...

This paper is motivated by the recent innovations regarding the taxation of cross-border savings that took place in the European Union and the United States. We develop a model to assess the functioning of the different systems of international taxation used on both sides of the Atlantic Ocean....

This paper proposes an analysis of the effects of consensus and preference aggregation on the consistency of pairwise comparisons. We define some boundary properties for the inconsistency of group preferences and investigate their relation with different inconsistency indices. Some results are...

In decision-making processes, it often occurs that the decision maker is asked to pairwise compare alternatives. His/her judgements over a set of pairs of alternatives can be collected into a matrix and some relevant properties, for instance, consistency, can be estimated. Consistency is a...

In this paper we show that the widely used normalization constraint SUM(i=1,n) wi = 1 does not apply to the priority vectors associated with reciprocal relations, whenever additive transitivity is involved. We show that misleading applications of this type of normalization may lead to...

In this paper we propose an approach to Social Network Analysis (SNA) based on fuzzy m-ary adjacency relations. In particular, we show that the dimension of the analysis can naturally be increased and interesting results can be derived. Therefore, fuzzy m-ary adjacency relations can be computed...

We propose two straightforward methods for deriving the priority vector associated with a fuzzy preference relation. Then, using transformations between multiplicative preference relations and fuzzy preference relations, we study the relationships between the priority vectors associated with...

Pairwise comparisons are a well-known method for the representation of the subjective preferences of a decision maker. Evaluating their inconsistency has been a widely studied and discussed topic and several indices have been proposed in the literature to perform this task. As an acceptable...

In this paper we present an overview of the soft consensus model in group decision making and we investigate the dynamical patterns generated by the fundamental pairwise preference interactions on which the model is based. The dynamical mechanism of the soft consensus model is driven by the...
