Women, Rails and Telegraphs: Information Spillovers and Collective Action

Funded Research Proposal

Social networks and media enable information diffusion in societies — and are thus at the core of collective decision making and action. The recent rise of many events which are critical for the political and corporate stakeholders, such as the Arab Spring and Occupy Wall Street, require information essential to individuals’ participation to spread among heterogeneous populations and over wide geographies.Read More

Shrouded in Structure: Challenges and Opportunities for a Friction-Based View of Network Research

Published Research

Whereas network ideas and approaches have become prominent in both the managerial and sociological literatures, we contend that the increasing emphasis on network structures and their evolution has distracted us from the important issue of whether and when networks actually work in the ways that our theories assume.Read More

Engineering Serendipity into Social and Knowledge Networks in Large Enterprises

Funded Research Proposal

An organization’s ability to innovate depends to a large extent on its ability to allow organizational learning to occur internally. It is not enough that knowledge gets imported into the organization; knowledge needs to also diffuse within the organization.Read More

Cooperation and Innovation in Green Industries: International Environmental Networks in Emerging Markets

Funded Research Proposal

To what extent do environmental stakeholders cooperate with each other? Does collaboration breed innovation? Is there collaboration across environmental issue-areas? This study will (1) map the network of international collaboration in critical environmental issue-areas and (2) reveal the precise ways in which the interactions of four key stakeholders affect competition and innovation in the field.Read More

Nuclear Research Networks in Emerging Markets: Collaboration & Competition in High-Tech Fields

Working Papers

To what extent do nuclear scientists in different countries collaborate with each other? What is the network structure of collaboration and competition? We argue that nuclear research networks, formed by reciprocal and horizontal interactions among specialists and the institutions within which they are embedded, evolve across developing economies in response to fluctuations in government spending.Read More

Balance Within and Across Domains: The Performance Implications of Exploration and Exploitation in Alliances

Published Research

Organizational research advocates that firms balance exploration and exploitation, yet it acknowledges inherent challenges in reconciling these opposing activities. To overcome these challenges, such research suggests that firms establish organizational separation between exploring and exploiting units or engage in temporal separation whereby they oscillate between exploration and exploitation over time.Read More

The Evolution of Alliance Portfolios: The Case of Unisys

Published Research

How do alliance portfolios evolve? We develop grounded theory based on Unisys’ case, which reveals how exogenous technological changes at the industry level and shifts in a firm’s strategy shape the composition of partners and the nature of alliance relationships.Read More

Balancing Exploration and Exploitation Within and Across Domains: Evaluation of Performance Implications in Alliance Portfolios

Organizational research advocates that firms balance exploration and exploitation, yet it acknowledges inherent challenges in reconciling these opposing activities. To overcome these challenges, such research suggests that firms establish organizational separation between exploring and exploiting units or engage in temporal separation whereby they oscillate between exploration and exploitation over time.Read More

Social Capital for Hire? Mobility of Technical Professionals and Firm Influence in Wireless Standards Committees

Published Research

The movement of personnel between firms has been shown to have important implications for firms, yet there has been little direct investigation of the underlying mechanisms. We propose that in addition to their human capital, mobile individuals carry social capital, affecting the outcomes of the firms they join and leave by altering the patterns of interaction between firms.Read More

Network Composition, Collaborative Ties, and Upgrading in Emerging-Market Firms: Lessons from the Argentine Autoparts Sector

Published Research

What types of relational and institutional mechanisms shape knowledge flows and the upgrading capabilities of emerging-market firms in the face of economic liberalization? We analyze the Argentine autoparts sector to distinguish the relative impact of different types of network relationships on a firm’s process and product upgrading.Read More

Home-Country Networks and Foreign Expansion

Published Research

We propose that home country network advantages shape firms’ foreign expansion. We argue that a social status advantage is transferable from one market to another as a signal of quality but that a brokerage advantage is more context-specific and difficult to transfer.Read More
