Modern financial systems exhibit a high degree of interdependence, with connections between financial institutions stemming from both the asset and the liability sides of their balance sheets. Networks--broadly understood as a collection of nodes and links between nodes--can be a useful representation of financial systems. By modeling economic interactions, network analysis can better explain certain economic phenomena. In this chapter, Allen and Babus argue that the use of network theories can enrich our understanding of financial systems. They explore several critical issues. First, they address the issue of systemic risk, by studying two questions: how resilient financial networks are to contagion, and how financial institutions form connections when exposed to the risk of contagion. Second, they consider how network theory can be used to explain freezes in the interbank market. Third, they examine how social networks can improve investment decisions and corporate governance, based on recent empirical results. Fourth, they examine the role of networks in distributing primary issues of securities. Finally, they consider the role of networks as a form of mutual monitoring, as in microfinance.

Zott and Amit explore the role of business models in creating value through networks. They review earlier, firm-centric views of value creation, including Porter’s value chain, the resource-based view, and the transaction costs approach. They point out that business models go well beyond classic views of network theory (e.g., topography and structure) and include notions of purpose, acceptance, fairness, coherence, and viability. Based on their earlier framework for e-business models, they explore the role of four major interlinked value drivers: efficiency, complementarities, lock-in, and novelty. They argue that the focal firm’s business model acts as both an engine for value-creation and an invaluable construct for understanding the firm’s role in relation to other business model participants in the networks in which it is embedded.

Although any manager would recognize the importance of “networking” in finding, developing, and retaining employees, human resource management traditionally has focused on individuals. In this chapter, the authors point out that core HR processes such as recruitment and hiring, training and development, performance management, and retention all depend on networks. They consider the importance of weak ties in matching employees with jobs and “structural holes” in promoting creativity. They urge managers to make the shift from an atomized view to a network view of human resources--from focusing on the “trees” to understanding the “forest.” They show that networks can boost efficiency and productivity by facilitating information sharing, attracting talent, and strengthening employees’ commitment to the firm. But networks may also pose risks such as “lift-outs,” in which a departing employee takes other workers in his or her network. The authors explore how managers need to understand the impact of networks and how to “manage” them.

The instant messaging generation, wired and integrated into broad, flat networks almost from birth, will not function as their predecessors did when injected into the social networks that form their professional organizations. IM’ers are creating their own network styles and content, as well as their own informal, back-channel networks, different from those of their more senior coworkers, and more compatible with their personal styles and loyalties. If their adoption of workplace communications norms indeed differs from that of their predecessors, how will these individuals function differently as employees, and how will organizations need to adapt their training, their managerial styles, and their expectations of employees’ motivations, performance, and loyalty to incorporate these new employees? After reviewing the literature on social networks, the authors explore a few prominent and visible trends that affect employers and employees: (1) changing communications technologies and their implication for social organization; (2) changing perception of fact, technique, and reality, and implications for authority and decision styles; and (3) outsourcing, downsizing, and the erosion of organizational loyalty. They then offer qualitative impressions, as well as insights from an online survey (of 80 respondents), and explore implications for managers and organizations.

Global networks of firms are rapidly replacing top-down, hierarchical organizations. Such networks, thanks to information technology and global communications systems, can respond to changes in international demand faster and more flexibly than rigid corporate organizations of the past. But by drawing together diverse cultures and individuals, these networks present new challenges to leaders. Traditional styles of leadership are not enough for this emerging environment. The kind of leadership style that leads to efficient execution in these global networks is different from the “do it and do it now” approach that might work in hierarchical organizations. Based on the author’s experience in the leading global accounting firm Touche Ross, serving as dean of the Wharton School, and heading his own corporate investment firm, this chapter discusses leadership in a networked, global environment.

The locus of innovation is shifting from the firm to the network. In contrast to developing standalone products, innovators are drawing together networks that deliver a personalized, co-created experience to the customer. This chapter describes a model in which nodal firms link communities of customers with communities of prequalified vendors. It examines cases from cardiac pacemakers to addressing diabetes and explores the implications of this shift for product and service innovation, value creation, and new sources of competitive advantage.

Telecommunications is a networked business, yet it traditionally has resisted a network-based view in its strategies and business models. In this chapter, Kevin Werbach explores this paradox, contrasting the worldview of Monists such as AT&T, who see the infrastructure as inseparable from the network, and Dualists such as Google, who see the network and its applications as distinct from the underlying infrastructure. Not surprisingly, AT&T is a proponent of “tiered access” whereas Google argues for “network neutrality.” Finally, Werbach examines how a more modular future might bridge the gap between those who seek to own and capitalize on the network and those who seek to expand it through more neutral offerings.

Social networks and word-of-mouth marketing are increasingly important, yet few current practices are based on a deep understanding of how the structure of networks can affect customer behavior and marketing outcomes. This chapter offers some critical observations on current word-of-mouth marketing practices and identifies four key questions that managers need to ask themselves before engaging in campaigns designed to leverage customer networks: Can we be confident that interpersonal influence or social contagion is really important? Why exactly would social contagion occur? Should we target key influentials? Can we identify and target those influentials? The answers to these questions cannot be taken for granted.

Biology remains the most extensive and complex information network on the planet. This chapter examines the nature of biological networks, including their inherent stability and risks to their resilience. After a general introduction exploring networks and biological systems, this chapter reviews (1) the evolution of biological networks; (2) principles that govern biological networks; and (3) measures of stability, productivity, and efficiency in biological networks. The authors use examples from food (energy) transfer in rainforests and coral reefs, as well as the creation of a biological network through colonization in Darwin’s Finches of the Galapagos Islands. Research shows that while large biological networks are inherently unstable, some are more stable than others.
