Topology of the World Trade Web

Economy, and consequently trade, is a fundamental part of human social organization which, until now, has not been studied within the network modelling framework. Networks are mathematical tools used in the modelling of a wide variety of systems in social and natural science. Examples of these networks range from metabolic and cell networks to technological webs. Here we present the first empirical characterization of the world trade web, that is, the network built upon the trade relationships between different countries in the world. This network displays the typical properties of complex networks, namely, scale-free degree distribution, the {\it small world} property, a high clustering coefficient and, in addition, degree-degree correlation between different vertices. All these properties make the world trade web a complex network, which is far from being well-described through a classical random network description

Managing supplier satisfaction: Social capital and resource dependence frameworks

Recently, supplier satisfaction has gained more attention both in practice and in academic research. However, the knowledge accumulation process is still in an embryonic and explorative phase. Likewise, supplier satisfaction measuring in practice may still benefit from an impetus from academia to be more widely used. This paper aims at considerably expanding understanding of supplier satisfaction by proposing to apply a social capital and a resource dependence theory perspective. We expect an abundance of social capital in a relationship to relate positively to supplier satisfaction, whilst power disequilibrium and dependence from the buyer are expected to negatively relate to supplier satisfaction. It is worth highlighting that, according to research rooted in Hofstede's cultural dimensions model, the perception and acceptance of power differences resulting from a situation of dependency is highly culture specific. We therefore further hypothesise that supplier satisfaction will be moderated by cultural differences and ask researchers to take the cultural dimension into accoun

Ensuring dynamic strategic fit of firms that compete globally in alliances and networks: proposing the Global SNA - Strategic Network Analysis - framework

In order to sustain their competitive advantage in the current increasingly globalized and turbulent context, more and more firms are competing globally in alliances and networks that oblige them to adopt new managerial paradigms and tools. However, their strategic analyses rarely take into account the strategic implications of these alliances and networks, considering their global relational characteristics, admittedly because of a lack of adequate tools to do so. This paper contributes to research that seeks to fill this gap by proposing the Global Strategic Network Analysis - SNA - framework. Its purpose is to help firms that compete globally in alliances and networks to carry out their strategic assessments and decision-making with a view to ensuring dynamic strategic fit from both a global and relational perspective
