This study investigates how the structure of a supply chain network in the domestic market influences the foreign direct investment (FDI) decisions of firms embedded in the network. We first describe the binary choice of firms on whether to invest through a coordination game of a fixed network with incomplete information of the firms’ profits, and we show that the unique equilibrium of the game...

There is an age-old question in all branches of network analysis. What makes an actor in a network important, courted, or sought? Both Crossley and Bonacich contend that rather than its intrinsic wealth or value, an actor's status lies in the structures of its interactions with other actors. Since pairwise relation data in a network can be stored in a two-dimensional array or matrix, graph theo...

In this paper, new measures of centrality that summarize the contact structure of social networks are proposed. The new measures use a cumulative nomination scheme based on the preliminary assumption that more central individuals will be nominated more often. Some of these measures are defined to characterize networks of different sizes and, by extension, networks made of many components. These...

The power grid is of crucial importance to the modern economy and in recent years it has drawn also the attention of researchers in the nascent field of complex network science. Most previous works in this field have been descriptive and mainly concerned with highlighting the structure that power grids share with other types of networked (e.g., small world). We propose and develop the first ste...

This paper presents QuickRank, an efficient algorithm for ranking individuals in a society, given a network that encodes their relationships, assuming that network possesses an accompanying hierarchical structure: e.g., the Enron email database together with the corporation’s organizational chart. The QuickRank design is founded on the “peer-review” principle, defined herein, and an hypothesis ...

Introduction: Bipolar Spectrum Disorders include a variety of mood disorders from bipolar II disorder to conditions characterized by hyperthymic mood states. It has been suggested that psychosocial factors also play an important role in bipolar disorders, in this study we have used social network analysis in order to better understand the social positions of those affected by bipolar spectrum d...

We study general properties of pairwise stable and Nash networks when players are ex-ante homogeneous. Rather than assuming a particular functional form utility, we impose link externality conditions on utility such as ordinal convexity strategic complements. Depending these rather weak notions externalities, show that various structure exist. For stronger versions the complements conditions, e...

The study of strategic behavior in large scale networks via standard game theoretical methods is a challenging, if not intractable, task. In this paper, we propose a way to approximate games played over networks of increasing size, by using the graph limiting concept of graphon. To this end, we introduce the new class of graphon games for populations of infinite size. We investigate existence a...

The increase in risk prevention investments the port-hinterland service network (PHSN) effectively enhances network’s ability to resist risks and improve sustainability stability of ocean transportation. Based on construction PHSN investment utility model, equilibrium strategy, related characteristics each participant complementary networks complete are analyzed. Similarly, subsidy policy gover...
