Performance implications of centrality in franchisee advice networks

Although the literature has provided ample evidence for the decisiveness of the franchisor–franchisee relationship in explaining organizational success or failure, performance effects of franchisee–franchisee relationships remain largely unexplored. Yet a growing body of research indicates that by building interfranchisee relationships, franchisees can form advice networks in the chain. Such networks offer privileged access to resources such as knowledge, information, and best practices that help individual franchisees to become more productive. In this context, we study linkages between a franchisee's centrality in franchisee relationships and various individual performance outcomes, using comprehensive data from franchisees in 3 different chains in the largest European franchise market, France. We find that conditional on the specific governance structure of each chain, the results document a strong impact of centrality in advice networks on franchisee performance. Accordingly, we offer theoretical contributions concerning knowledge‐sharing processes in franchise chains, and managerial implications as regards more effective cooperation management in practice, from the perspective of both a franchisee and a franchisor.     

The influence of supply network structure on firm innovation

In this study, we examine the structural characteristics of supply networks and investigate the relationship between a firm's supply network accessibility and interconnectedness and its innovation output. We also examine potential moderating effects of absorptive capacity and supply network partner innovativeness on innovation output. We hypothesize that firms will experience greater innovation output from (1) higher levels of supply network accessibility and supply network interconnectedness, (2) the interaction between the levels of these two structural characteristics, (3) the moderating role of absorptive capacity on supply network accessibility and the moderating role of supply network partner innovativeness on supply network interconnectedness. Supply network partner relationships are drawn in the context of the electronics industry using data from multiple sources. We use social network analysis to create measures for each supply network structural characteristic. Using regression techniques to test the relationship between these structural characteristics and firm innovation for a sample of 390 firms, our findings suggest that supply network accessibility has a significant association with a firm's innovation output. The results also indicate that interconnected supply networks strengthen the association between supply network accessibility and innovation output. Moreover, the influence of the two structural characteristics on innovation output can be enhanced by a firm's absorptive capacity and level of supply network partner innovativeness. By addressing the need for deeper structural analysis, this study contributes to supply chain research by accounting for the embedded nature of ties in supply networks, and showing how these structural characteristics influence the knowledge and information flows residing within a firm's supply network.     

Research on e-commerce transaction networks using multi-agent modelling and open application programming interface

We provide a formal definition of an e-commerce transaction network. Agent-based modelling is used to simulate e-commerce transaction networks. For real-world analysis, we studied the open application programming interfaces (APIs) from eBay and Taobao e-commerce websites and captured real transaction data. Pajek is used to visualise the agent relationships in the transaction network. We derived one-mode networks from the transaction network and analysed them using degree and betweenness centrality. Integrating multi-agent modelling, open APIs and social network analysis, we propose a new way to study large-scale e-commerce systems.     

Opinion dynamics and wisdom under conformity

We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors’ expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an agent׳s social influence on the long-run group opinion is increasing in network centrality and decreasing in conformity. Concerning efficiency of information aggregation or “wisdom” of the society, it turns out that misrepresentation of opinions need not undermine wisdom, but may even enhance it. Given the network, we provide the optimal distribution of conformity levels in the society and show which agents should be more conforming in order to increase wisdom.     

Public–Private Partnerships in Health Services Delivery

Abstract

In this article, we conceptualize public–private partnerships (PPPs) from a network organizations perspective, and apply interorganizational relations (IOR) to study fifteen PPPs in a district health system in the state of Rajasthan in India. We find that the Government occupies a dominant position in the network because of the centrality of its functions, authority and control over resources and information. There is greater reliance on formal mechanisms of co-ordination. For effective network governance, it is imperative to reduce the power asymmetry, develop horizontal co-ordination, trust and social capital, and enhance public managers’ capacity for effectively managing interorganizational relationships.     

How Do Social Networks Influence the Employment Prospects of People with Disabilities?

We explore the role of social networks used by people with disabilities for finding employment. In addition, we outline obstacles to network building for those with a disability. We contend that this group is often constrained and they underutilize their networks during job searches. Both factors are likely to result in negative employment outcomes and contribute to the employment gap between those with and without a disability. We outline how key network characteristics such as homophily, tie strength, and centrality influence job search outcomes for those with a disability differently than for those without a disability. Furthermore, we propose that although individuals with disabilities develop and rely upon networks that are comprised of close bonds with similar individuals that are either unemployed or underemployed in lower status positions, optimal networks for employment purposes should consist of diverse acquaintances that occupy central positions and higher status jobs within organizations. Finally, we outline propositions to guide future research on this neglected topic and also suggest practical implications.     

A network approach to work-family conflict

Most human behaviours, including those instrumental for reducing Work–Family Conflict (WFC), take place in the context of social relationships. However, the role of social networks in an individual's WFC goal pursuit process has not received sufficient attention, as most current research is dominated by an agentic perspective that argues that individuals possess the capabilities to change the demands and resources associated with their roles freely. We believe that the reality faced by many workers is more composite, as the various work and family stakeholders present in an individual's network can create significant constraints and opportunities that are capable of inhibiting or enhancing their agency. In this paper, we aim to examine how the ecosystem of network relationships in an individual’ social network can influence his or her overall capability to minimise WFC. Building on insights from dynamic network theory, a recently introduced framework in the social network literature, we propose a conceptual model that explains the specific roles that work and family stakeholders (i.e., supporters, preventers, resistors, reactors, negators, interactants, or observers) can assume with respect to goal strivers' attempts to manage WFC. Building on prior work-family and social network research, we illustrate how two characteristics of the network in which an individual is embedded (i.e., centrality and density) can shape the magnitude of social network influence on WFC. Implications for theory and practice are also discussed.     

董事联结能抑制薪酬粘性吗?——管理层权力的中介效应研究

作为一种信息传导路径与资源共享平台,董事联结能为高管权力监督、薪酬粘性治理发挥重要功效。基于社会网络理论与弱联结优势理论,考察董事联结对高管薪酬粘性的影响机理,并探究管理层权力在其中的作用路径。研究发现,董事网络中心度越高,高管薪酬粘性越弱;管理层权力在二者关系中存在部分中介效应,约束管理层权力是网络位置降低薪酬粘性的一条有效路径。进一步区分联结强度后发现,内部董事强联结通过扩大管理层权力加剧高管薪酬粘性,外部董事弱联结通过约束管理层权力抑制高管薪酬粘性,且弱联结优势下管理层权力的中介效应比例最大。以高管任期作为管理层权力的工具变量缓解潜在的内生性影响,基准回归结论比较稳健。     

Making the right friends: A social network perspective on newcomer socialization in teams

Despite the prevalence of work teams in organizations, how newcomers become integrated into teams remains an understudied area. Drawing on research related to indirect social resources, in this paper we employ a social network perspective to examine how close teammates' friendship centrality can facilitate newcomers' adjustment by fostering the newcomers' own social capital in teams and promoting their subsequent task performance. Furthermore, our model incorporates institutionalized socialization tactics and political skill as two contingencies that can further strengthen the positive effects of indirect social resources on newcomers' adjustment. In a time-lagged study using multiple sources of data, we found good support for our hypotheses. Specifically, close teammates' friendship centrality was positively related to newcomers' task performance through the mediating effect of newcomers' own friendship centrality in teams. The two moderators further strengthened this indirect effect. Overall, this study highlights the importance of “making the right friends” to facilitate newcomer adjustment into teams.

An institutional perspective of public policy and network effects in the renewable energy industry: enablers or disablers of entrepreneurial behaviour and innovation?

This study extends theory on the effects of public policies stimulating technology demand and of industry network ties on firm-level entrepreneurial behaviour. We take an institutional perspective to develop a theoretical model examining the mechanisms through which public policies, regulatory uncertainty, and industry network ties affect firm-level entrepreneurial decision-making processes and the ability to introduce highly innovative products and to sustain superior performance. We focus on firm-level effects, which enables the study of the tension between institutional pressures of homogeneity and competitive pressures of heterogeneity for entrepreneurial decision-making processes in environments characterized by policy-induced market demands. To test our hypotheses, we draw on data from a large-scale survey among German renewable energy firms. Our results show that public policies can constrain firm innovativeness and risk-taking behaviour because they steer firms towards a more conservative attitude and discourage the pursuit of high-risk innovation projects. However, firms can counteract these influences and enhance their innovativeness by maintaining close network ties with research associations as we find that innovativeness and a highly innovative product portfolio are key success factors. In summary, these findings provide important implications for the study of public policy effects, industry network ties and entrepreneurial behaviour.

Passion Isn't Always a Good Thing: Examining Entrepreneurs' Network Centrality and Financial Performance with a Dualistic Model of Passion

We propose a conceptual model that links entrepreneurs' passion, network centrality, and financial performance, and test this model with small business managers in formal business networking groups. Drawing on the dualistic model of passion, we explore the relationships that harmonious and obsessive passion have with financial performance, mediated by network centrality. Results indicate that harmoniously passionate entrepreneurs had higher out‐degree centrality in their networking group (i.e., they were more inclined to seek out members to discuss work issues), which increased the income they received from peer referrals and, ultimately, business income. Obsessively passionate entrepreneurs had lower in‐degree centrality (i.e., they were less likely to be approached by peers), and in turn received less income from referrals and less business income. These findings highlight that entrepreneurial passion does not always result in positive financial outcomes – the type of passion makes a difference. Implications for research and practice are discussed.     

Networks vs. market methods in high-tech venture fundraising: the impact of institutional environment

This study examines how institutional environmental factors, including cultural norm, state regulatory system and venture capital market, influence the high-tech entrepreneur's choice for using network vs. market methods when approaching prospective investors at the early stage of their new venture creation. We collected comparative data through on-site interviews and questionnaire survey with 128 high-tech entrepreneurs in Singapore (a newly industrialised economy) and 250 in Beijing, China (an emerging economy). Our findings suggest that a culture emphasising the value of social obligation, the under-development of the legal/regulatory system and the immaturity of the venture capital market increased the proclivity of entrepreneurs to use network methods. Moreover, entrepreneurs who value networks higher in social obligation than in information transfer are more likely to choose personal ties instead of business ties. This study enhances our understanding of how high-tech entrepreneurs in emerging economies choose between networks and market methods in venture fundraising, and offers suggestions on how public policy makers in these economies can improve the institutional environment of their regions to promote high-tech new venture creation.     

Collaboration,Co-Production,Networks: Convergence of theories

Abstract

This article suggests a framework to study service delivery networks that draws on the theories of collaboration, co-production, and networks combined. We introduce four dimensions of co-production under ‘coproduction-oriented collaborations’. This framework allows us to ‘zoom in and zoom out’ when we study networks. Using the case method approach, the framework is applied to analyse four networks in Singapore. Findings suggest that network process, network structure, and characteristics of actors are crucial to a network’s performance and coproduction’s effectiveness. This article also offers implications for practice that in certain contexts the usage of these concepts is for managerial effectiveness and not for enhancing democratic values.     

The Role of Information and Influence in Social Networks

A bstract .   This article examines two mechanisms through which social networks are related to job mobility: (1) access to diverse sources of information about job openings and (2) nonredundant sources of influence. Using data on job changing and social networks among television station managers, we assess the extent to which job information and influence variables mediate the relationship between social network structure and getting a better job. Results indicate that there is an association between job mobility and having nonredundant contacts, but our measures of the information and influence mechanisms are not significant mediators. We conclude by reexamining the network-resource model that forms the basis for much of the research on the relationship between social networks and job mobility.     

The problem of employees' network centrality and supervisors' error in performance appraisal: A multilevel theory

This article reveals an unexplored paradox for HR managers: the centrality of an employee in the social network benefits performance but hampers performance appraisal because it affects supervisors' rating errors. Central employees can be erroneously rated high on performance even when they are not high performers because supervisors tend to overappraise their performance. A distinction is made between rating precision, which depends on supervisors' uncertainty regarding employees' performance, and rating accuracy, which depends on supervisors' bias in favor of employees. Employee centrality is posited to be beneficial to precision but deleterious to accuracy because it regulates the diffusion of positive information, status, and power, all of which distort supervisors' capacity and motivation to accurately appraise performance. It is then argued that rating errors caused by network centrality affect aggregate perceptions of justice in organizations. When employees are highly connected to each other in a dense network, organizations have a strong and positive justice climate. Yet when some employees are more central than others in a centralized network, organizations have a negative and weak justice climate. The article contributes to the literature because it identifies an unexplored dark side of network centrality and offers recommendations for HR managers to cope with its deleterious consequences and for scholars to study them.     

Social networks,employment and worker discouragement: Evidence from South Africa

Social networks are increasingly being recognized as having an important influence on labour market outcomes, since they facilitate the exchange of job related information. Access to information about job opportunities as well as perceptions about the buoyancy of the labour market depend critically on the social structures and the social networks to which labour market participants belong. In this paper, we examine the impact of information externalities generated through network membership on labour market status. Using Census data from South Africa, a country characterized by high levels of unemployment and worker discouragement, we adopt an econometric approach that aims to minimise the problems of omitted variable bias that have plagued many previous studies of the impact of social networks. Our results suggest that social networks may enhance employment probabilities by an additional 3–12%, and that failure to adequately control for omitted variables would lead to substantial over-estimates of the network co-efficient. In contrast, the impact of social networks on reducing worker discouragement is much smaller, at between 1 and 2%.     

Heterogeneity and Specificity of Inter-Firm Knowledge Flows in Innovation Networks

abstract    Literature on innovation networks reveals little of to what extent different types of knowledge are exchanged and combined by collaborating firms to foster innovation. Based on field research in the aerospace industrial cluster of Rome, this study investigates the exchange of technological, market and managerial knowledge. Using social network analysis, the paper shows that the three types of knowledge are unevenly distributed and exchanged, thus revealing that the process of exchange is knowledge-specific. Further, it is found that in most collaborative relationships, partners exchange technological knowledge together with market and managerial knowledge, emphasizing the complex nature of the innovation process which requires access to and recombination of diverse knowledge. This phenomenon concerns not only large companies, but also small-to-medium enterprises. The reconsideration of the relative salience of the three types of knowledge has remarkable managerial and theoretical implications, which are developed in terms of propositions offered for further research.     

Method towards discovering potential opportunity information during cross-organisational business processes using role identification analysis within complex social network

ABSTRACT

The key to discover potential opportunity information in cross-organisation business processes (COBPs) is to identify the primary roles and actors, i.e. how to obtain their associations according to the interactive behaviours within the complex social networks. The information of roles in COBPs is commonly considered important and explicitly related with activities contained in COBPs. In this paper, we define a role as a configurable resource model integrating the capabilities and knowledge required to the qualified actors. Furthermore, we introduce two networks named as role-based interactive behaviour network and handover of work social network to investigate the information on roles. How to build the complex social network mapped on roles from COBPs is also discussed, and an approach to obtain the potential opportunity information is proposed by combining with the significance of roles and actors. The simulation result shows that the primary roles may not completely correspond to the central position in networks, but they are closely associated with more reliable actors.
