On the formation of interaction networks in social coordination games

There are many situations where two interacting individuals can benefit from coordinating their actions. We examine the endogenous choice of partners in such social coordination games and the implications for resulting play. We model the interaction pattern as a network where individuals periodically have the discretion to add or sever links to other players. With such endogenous interaction patterns we see multiple stochastically stable states of play, including some that involve play of equilibria in the coordination game that are neither efficient nor risk-dominant. Thus the endogenous network structure not only has implications for the interaction pattern that emerges, but it also has a significant impact on the play in the coordination game relative to what would arise if the same interaction network were exogenous.

Strongly stable networks

We analyze the formation of networks among individuals. In particular, we examine the existence of networks that are stable against changes in links by any coalition of individuals. We show that to investigate the existence of such strongly stable networks one can restrict focus on a component-wise egalitarian allocation of value. We show that when such strongly stable networks exist they coincide with the set of efficient networks (those maximizing the total productive value). We show that the existence of strongly stable networks is equivalent to core existence in a derived cooperative game and use that result to characterize the class of value functions for which there exist strongly stable networks via a “top convexity” condition on the value function on networks. We also consider a variation on strong stability where players can make side payments, and examine situations where value functions may be non-anonymous—depending on player labels.     

Developing social capital to achieve superior internationalization: A conceptual model

A conceptual model is proposed for analyzing the strategies of startups in the context of building social capital to achieve superior performance in internationalization. The study responds to calls for theoretical predictions based on comprehensive distinctions of network relationships, such as in the strength, number and content of ties. The effect of tie characteristics on formulating startup internationalization strategies and on subsequent performance depends on the combination of many weak ties and a few strong ties.

基于Meta分析的供应链网络嵌入性与协同创新绩效关系研究

供应链企业在合作中相互产生嵌入行为对高效整合链上资源以提高协同创新绩效至关重要,然而,两者之间的关系至今尚未形成一致性研究结论。本文利用Meta分析方法,以60篇相关文献、118个效应值、17911个独立样本作为研究对象,探究了网络嵌入性及各维度与协同创新绩效的整体效应,并运用亚组分析明晰了调节变量在两者关系中的调节作用。研究表明：网络嵌入性及其子维与协同创新绩效具有显著的正相关关系。另外,行业类型、区位因素、绩效类型及实证研究方法的不同均会导致研究结果不一致。本研究结论在一定程度上为网络嵌入性与协同创新绩效的关系研究提供了理论依据,同时也为供应链企业通过网络嵌入性提高创新能力提供了可资借鉴的参考思路。     

The use of management control mechanisms by public organizations with a network coordination role: A case study in the port industry

Our paper addresses two gaps in the literature on management control mechanisms in the context of inter-organizational relationships. Firstly, several studies have focused on one-to-one relationships, but few take a network perspective which analyses the deployment of management control mechanisms in the context of networks involving multiple interactions between organizations. Secondly, even fewer studies have specifically tackled the use of these mechanisms in the context of mixed-type networks, where a public organization acts as the network coordinator responsible for key governance activities. This is the position in Ports, which are collectives of several related organizations and in which one organization – the “port authority” – assumes the role of network coordinator. In this paper we report the results of a case study, the aims of which were: to identify the management control mechanisms deployed, or relied upon, by the Portuguese Port Authority in the Port of Aveiro in the exercise of its coordinating role; and to discern – on the basis of theoretical reasoning and empirical evidence – the factors explaining the nature and use of these mechanisms.Several conclusions emerged from the study. A general conclusion was that our prior literature-based theorization is generally consistent with the case observations. That is, in mixed-type networks, the nature and use of management control mechanisms by the public organization acting as a network coordinator seems to be shaped by its assessment of motivations to cooperate and of the contribution to network performance of the various organizations involved in the network. Other more specific conclusions are encapsulated in a “coordination framework”, which relates those assessments to specific features of the management control mechanisms. Crucially, our results provide insights into the roles of public organizations acting as network coordinators in the context of mixed-type networks, and, in general, on the nature of the numerous such public organizations in today's economy and society.

Interpartner legitimacy in regional strategic networks

Our aim is to add to the knowledge on a network level, focusing on if, and how, interpartner legitimacy affects the success or failure of network formation and development processes. Existing network theories and research tend to focus on resource exchange rather than on how actors perceive each other in terms of being legitimate or not. The purpose of the article is to analyze the interpartner legitimacy's influence on the formation and development processes of regional strategic networks (RSNs) from a network level. Two Swedish cases are discussed in terms of pragmatic, moral and cognitive interpartner legitimacy. The cases and the following discussion illuminate that interpartner legitimacy is important to incorporate into the analytical model if we wish to understand the processes of negotiations on the rules and norms which set the possibilities for survival of multi-actor interactions.
