We reconcile two conflicting views of the network centralization effect on team performance. In one view, a centralized network is problematic because it limits knowledge transfer, making it harder for team members to discover productive combinations of their know-how and expertise. In the alternative view, the limits on knowledge transfer encourage search and experimentation, leading to the discovery of more valuable ideas. We maintain the two sides are not opposed but reflect two distinct ways centralization can affect a team’s shared problem-solving framework. The shared framework in our research is a shared language. We contend that team network centralization affects both how quickly a shared language emerges and the performance implications of the shared language that develops. We analyze the performance of 77 teams working to identify abstract symbols for 15 trials. Teams work under network conditions that vary with respect to centralization. Results indicate that centralized teams take longer to develop a shared language, but centralized teams also create a shared language that is more beneficial for performance. The findings also indicate that the highest performing teams are assigned to networks that combine elements of a centralized and a decentralized network.

We renovate a classic experiment to define a research platform that provides data on network behavior and the causal effect of access to structural holes. Our hypothesis is that people are perceived to be leaders when they behave as network brokers, which is to say, when they coordinate information across structural holes. We focus on the perception of leadership to connect with the many field studies in which access to structural holes predicts success measures keyed to leadership. Our hypothesis is clearly supported. The broker-leader association we report is very similar in strength and form to broker-success associations reported in previous research. At the same time, it is also clear that people adapt to their randomly assigned network, re-shaping it to suit preferences that in some part emerge in team deliberations or outside the experiment. A modification to our hypothesis — at least for these small laboratory teams — is that monopoly brokerage is key to being cited as team leader. Leadership is ambiguous when multiple people are positioned to be brokers unless one person emerges by his or her network behavior as a monopoly broker. Our summary conclusion is that access to structural holes can be causal to the perception of leadership, a characteristic implicit in many success measures used to document the broker-success association.

We explore the difference between the rights and obligations specified in the legally binding contracts formalizing consumer transactions and how sellers behave in practice. We argue that institutional factors such as the cost and availability of litigation and the spread of reputational information about past performance shape sellers' actions in conjunction with the formal contract. Moreover, the effects of formal contracts, reputation and the availability of litigation on the rights consumers enjoy are interdependent with each other. As a result, researchers and policy makers seeking to protect consumers cannot confine their analysis to the language of legally binding contracts.
What I'm Working on Right Now
Hagay C. Volvovsky, Collaboration at the Tower of Babel: The Meaning of Cooperation and the Foundations of Long-Term Exchange
This paper is the first to propose and validate a general process by which exchange partners arrive at a mutual understanding of what actions constitute cooperation and defection in changing and complex environments, thereby making cooperation possible. Past research has largely bracketed the process by which such shared understandings are reached. This paper shows that by directly analyzing this process, we gain unique insight into the foundations of the cooperative agreements and relationships that undergird organizations and markets. At the heart of the analytic strategy is the differentiation between two contexts: one in which exchange partners can rely on established, pre-existing, commonly known frameworks and one in which the mutual understanding cannot be achieved without the joint development of a new framework. A set of online experiments validates the key theoretical implication, which is that when established frameworks are unavailable, long-term exchange relationships help forge mutual understandings that support greater cooperation. By contrast, when relationships are not needed to forge mutual understanding, they may not be valuable for supporting cooperation.
Hagay C. Volvovsky, Revising Economic Action and Social Structure: The Role of Embeddedness in the Age of Amazon
Network scholars posit that networks provide better reputational enforcement than market reputation (i.e., the reputation that would emerge from a sample of market participants). In this view, reputational signals are local to social network neighborhoods. Because it is costly to communicate with strangers, and there is little reason to trust them, reputational signals are stronger in the presence of shared third parties and decay with network distance. Consequentially, reputational sanctions and norm enforcement are also local to the network. Yet, the rise of reputational aggregation platforms such as Amazon and eBay call these mechanisms into question. In this paper, I identify an additional mechanism driving network-based reputational enforcement, one that places a boundary condition on both network and market based reputational enforcement. I argue that the informativeness of a reputational signal from A to B about C increases in relation to B’s belief that A used the same coordination framework B would in making her evaluation of C. The closer A’s framework is to B’s, the more informative the signal. When the underlying exchange relies on a well-established coordination framework, reputational signals from socially distant actors become informative, making market reputation and the platforms that aggregate it far more effective in providing reputational enforcement than social networks and reducing actors’ reliance on social networks for partner selection. Conversely when well-established frameworks are unavailable, reputational signals from strangers about whose frameworks you have little information become uninformative, rendering platforms ineffective. When that is the case, there are good reasons to believe that frameworks - and thus reputations and reputational enforcement – are local to social network neighborhoods, and social networks continue to play a large role in facilitating cooperation and guiding partner selection.
Hagay C. Volvovsky and Lisa Bernstein, People as a Contract Provision: How Organizations Manipulate Social Networks to Bond Strategic Alliances
We explore how organizations facilitate trust, cooperation and innovation in strategic alliances via the strategic exchange of personnel. Employees transferring from one partner organization to another become brokers bridging the structural hole between the two. Their unique position allows them to successfully communicate with and understand members of both organizations, thus facilitating knowledge transfer and reducing the possibility that cultural differences will lead to a breakdown in the relationship. Furthermore, transferring employees' personal relationships in organization they depart bond their actions as agents of the organization they join. Employees leaving organization A to join organization B are far less likely to act opportunistically towards their former colleagues in A. We support these propositions using a comprehensive dataset of strategic alliances in the biotechnology industry, from its inception in the 1980's to 2010.
