Social resources research has linked activated ties to outcomes-but not to the core networks from which the ties came. This study shifts the focus to the question of how networks allocate resources. The activation of core network ties is analyzed in a nonroutine situation-a hurricane-to determine how core network structure affects the degree to which individuals activate core network ties to gain one type of social resource-informal support. Results show that the structures of individuals' core networks affect the degree to which individuals activate ties from those networks to gain informal support. Individuals embedded in higher-density core networks (i.e., alters are connected to one another), core networks with more gender diversity (i.e., a mix of men and women), and networks that contain higher proportions of men, kin, and younger individuals, activated core network ties for informal support to a greater degree than did individuals embedded in core networks lacking these characteristics. The conclusions consider the study's implications for understanding resource activation in the contexts of social support and job searches.

Interfirm contracts represent common economic relations in the marketplace; they are also deeply embedded in social relations and social institutions. In the context of China's transitional economy, this study examines how three mechanisms-economizing transaction costs, network-based social relations, and institutional links-- affect interfirm contractual relationships in (1) the choice of search channels for contractual partners, (2) the formality and provisions in a contract, and (3) the intensity of social interaction in contract implementation. Empirical evidence is drawn from information collected on 877 contracts from 620 firms in two Chinese cities, Beijing and Guangzhou. The authors find distinct roles of social relations, institutional links, and regulatory environments in the initiation of contractual partners and the forms of contracts adopted, whereas transaction-specific factors play a significant role in the intensity of social interaction in contract implementation. These findings suggest the interplay among economic calculativeness, social networks and institutional links, and the complementarity in the underlying theoretical ideas.

The article investigates how social embeddedness affects an organization's acquisition and cost of financial capital in middle-market banking-a lucrative but understudied financial sector. Using existing theory and original fieldwork, Author develops a framework to explain how embeddedness can influence which firms get capital and at what cost. I then statistically examine my claims using national data on small-business lending. At the level of dyadic ties, author finds that firms that embed their commercial transactions with their lender in social attachments receive lower interest rates on loans. At the network level, firms are more likely to get loans and to receive lower interest rates on loans if their network of bank ties has a mix of embedded ties and arm's-length ties. These network effects arise because embedded ties motivate network partners to share private resources, while arm's-length ties facilitate access to public information on market prices and loan opportunities so that the benefits of different types of ties are optimized within one network. Author concludes with a discussion of how the value produced by a network is at a premium when it creates a bridge that links the public information of markets with the private resources of relationships.

Economic actors confront various forms of uncertainty making decisions, and how they deal with these obstacles may affect their success in accomplishing their goals. This study examines the means by which relationship managers in a major commercial bank attempt to close transactions with their corporate customers. It is hypothesized that under conditions of high uncertainty, bankers will rely on colleagues with whom they are strongly tied for advice on and support of their deals. Drawing on recent network theory, it is also hypothesized that transactions in which bankers use relatively sparse approval networks are more likely to successfully close than are transactions involving dense approval networks. Both hypotheses are supported. Bankers are faced with a strategic paradox: Their tendency to rely on those they trust in dealing with uncertainty creates conditions that render deals less likely to be closed successfully. This paradox represents an example of unanticipated consequences of purposive social action.
Hazards of the Market: The Continuity and Dissolution of Interorganizational Market Relationships [статья]
Опубликовано на портале: 22-05-2004Wayne E. Baker, Robert R. Faulkner, Gene A. Fisher American Sociological Review. 1998. Vol. 63. No. 2. P. 147-176.
We propose a theory of the market as an "intertemporal" process that integrates multiple theoretical perspectives. Using event-history methods, we analyze the dissolution of interorganizational market ties between advertising agencies and their clients as a function of three forces-competition, power, and institutional forces. The informal "rules of exchange" institutionalized in the "emergence" phase of the advertising services market include exclusivity (sole-source) and loyalty (infrequent switching). We find that most exchange relationships between advertising agencies and their clients are indeed exclusive, and most last for several years; but competition, power, and institutional forces support or undermine these rules. Most institutional forces reduce the risk of dissolution of agency-client ties. Powerful advertising agencies mobilize resources to increase tie stability, but powerful clients mobilize resources to increase or decrease stability. Competition is the weakest market force, but it has a consistent and substantial effect on tie dissolution: Competition always increases the risk of dissolution. We conclude that the market is institutionalized as imperfectly repeated patterns of exchange, because competition and changing norms about the duration of market ties destabilize market relationships.

We examine how the structure and content of individuals' networks in the workplace affect intraorganizational mobility. Consistent with prior research, we find that an individual's mobility is enhanced by having a large, sparse network of informal ties for acquiring information and resources. However, in contrast to previous work, we emphasize the importance of consistent role expectations for performance and mobility. We find evidence that well-defined performance expectations are more likely to arise from a small, dense network of individuals. We develop a typology of network contents and document the interaction between network structure and content in analyses of mobility among employees of a high-technology firm. We also examine how the effects of tie duration on mobility vary by tie content. We discuss the implications of our results for theory and research on networks and organizational mobility.

Most research on social networks and immigrant incorporation focuses on the short-term and positive functions of networks, neglecting changes in networks over time. Author present a dynamic and variable portrayal of networks to demonstrate how they gradually assume different forms and functions for women and for men that differentially affect settlement outcomes, particularly opportunities to become legal. The gendered social relations of neighborhood, work, and voluntary associations interact to produce this outcome. The conclusions suggest that social networks can both strengthen and weaken over time, can change differentially for different segments of the immigrant community, and therefore can have disparate effects on incorporation.

Although questions about social cohesion lie at the core of our discipline, definitions are often vague and difficult to operationalize. Here, research on social cohesion and social embeddedness is linked by developing a concept of structural cohesion based on network node connectivity. Structural cohesion is defined as the minimum number of actors who, if removed from a group, would disconnect the group. A structural dimension of embeddedness can then be defined through the hierarchical nesting of these cohesive structures. The empirical applicability of nestedness is demonstrated in two dramatically different substantive settings, and additional theoretical implications with reference to a wide array of substantive fields are discussed.
The structure of founding teams: Homophily, strong ties, and isolation among U.S. entrepreneurs [статья]

The mechanisms governing the composition of formal social groups (e.g., task groups, organizational founding teams) remain poorly understood, owing to (1) a lack of representative sampling from groups found in the general population, (2) a "success" bias among researchers that leads them to consider only those groups that actually emerge and survive, and (3) a restrictive focus on some theorized mechanisms of group composition (e.g., homophily) to the exclusion of others. These shortcomings are addressed by analyzing a unique, representative data set of organizational founding teams sampled from the U.S. population. Rather than simply considering the properties of those founding teams that are empirically observed, a novel quantitative methodology generates the distribution of all possible teams, based on combinations of individual and relational characteristics. This methodology permits the exploration of five mechanisms of group composition-those based on homophily, functionality, status expectations, network constraint, and ecological constraint. Findings suggest that homophily and network constraints based on strong ties have the most pronounced effect on group composition. Social isolation (i.e., exclusion from a group) is more likely to occur as a result of ecological constraints on the availability of similar alters in a locality than as a result of status varying membership choices.
