Networks & Organization Session 1: Introduction Instructor: Christopher Wheat
Why Study Networks? Networks & Organization – S01.2 Sociological significance Sociology is essentially about the study of social structure The relationship is one of the key uniquely sociological constructs Ubiquity of social networks Frequent claim that “it’s not what you know, but who you know” Everyone’s talking about social networking (Facebook, MySpace, etc.) © MIT Sloan School of Management
Why Study Networks…Critically? Networks & Organization – S01.3 Some studies of “social networks” aren’t so clearly sociological Is documenting the increased use of LinkedIn or country-by- country differences in MySpace usage really a network study? Some claims about “networking” aren’t self evidently true… How would you know if it’s not what you know? Main objectives: Become a critical consumer of social network research Become a proficient producer of (well-grounded) social network research © MIT Sloan School of Management
The Main Question Networks & Organization – S01.4 In what ways are relationships, exchanges, and the structure thereof implicated in social processes and outcomes? Part I: Developing Network Analytic Methods Basic Structure: e.g. Dyads, Triads, Groups & Roles Inference Methods for Identifying Structural Features Part II: Applying Network Methods to Management and Organizational Phenomena Group Processes, Labor Markets, Innovation, Strategy & Global Management © MIT Sloan School of Management
Basic Structure: Dyads Networks & Organization – S01.5 What can happen in a simple relationship? Symmetric processes: Information sharing Mutual influence Asymmetric processes: Power & Influence Method question: How can we tease apart one from the other? © MIT Sloan School of Management
Basic Structure: Triads Networks & Organization – S01.6 What can we learn from ties among three actors that we can’t learn from ties between two? Micro-processes of group formation Brokerage Differential popularity & attractiveness structures Why do we care about this in the study of social organization? © MIT Sloan School of Management
Global Structure: Complete Networks Networks & Organization – S01.7 What can you learn from a complete network that you can’t learn from local structure? Contextual centrality Small world phenomena What kinds of organizational questions does this relate to? © MIT Sloan School of Management
Networks and Role Structures Networks & Organization – S01.8 Do relationships between actors tell us anything about typologies of these actors? Defining equivalence of relational patterns Relationships between hypothesized roles as an object of study Methods to elicit role structures How do network-identified roles shape organizational outcomes? What constitutes a “sufficient” study of organizational roles? Do some roles perform better than others? © MIT Sloan School of Management
Network Dynamics Networks & Organization – S01.9 How do networks change over time? What role does the agency of individual actors play in shaping network dynamics? How can change in networks be effectively modeled? What kind of structural claims can be made without a considering dynamics? © MIT Sloan School of Management
Cognitive Networks Networks & Organization – S01.10 Do perceptions of & beliefs about networks matter? Do actors agree, in general, in their perceptions of network structure? How should we think about networks if they don’t? What are some of the consequences of actor disagreement about network structure? © MIT Sloan School of Management
Inference and Network Structure Networks & Organization – S01.11 How can we statistically assess the relevance of structural features of networks What assumptions do we need to make in order to draw statistical conclusions? Does this change the way we think about “non-parametric” social network analyses? © MIT Sloan School of Management
Networks and Group Process Networks & Organization – S01.12 How are individuals within groups affected by network structures? Homophily processes Group demography Antecedents of creativity & productivity © MIT Sloan School of Management
Networks and Labor Markets Networks & Organization – S01.13 In what ways do networks help us understand differential labor market outcomes? How do people find out about jobs? How do jobs find out about people? How do network explanations of labor market outcomes compare to other explanations? © MIT Sloan School of Management
Networks, Performance and Competition Networks & Organization – S01.14 How is firm and organizational performance affected by network position? Network position as a source of structural advantage Status-based competition Alliance & interlock structures and performance © MIT Sloan School of Management
Networks, Technology and Innovation Networks & Organization – S01.15 Are networks useful in understanding the role of technology and innovation in organizational outcomes Diffusion of technology Technology-based competition Collaboration processes between organizations © MIT Sloan School of Management
Networks and the Global Economy Networks & Organization – S01.16 Are network analytic constructs useful in explaining the social structure of the global economy? Do network positions affect states in the same ways that they affect individuals and/or organizations? Are there other explanations for global economic structures and outcomes? © MIT Sloan School of Management
Seminar Mechanics: Readings Networks & Organization – S01.17 Required reading All available on-line (for free) May change slightly—watch the website! Open to suggestions for some changes Optional reading Articles that are related but not central Reference readings from textbooks Wasserman & Faust: Good general overview if not a bit dated de Nooy, et. al.: Kind of a manual for Pajek, but helpful Scott: Interesting overview Doreian, et. al.: Very specific text on blockmodeling © MIT Sloan School of Management
