Do Institutional Reforms Perpetuate or Mitigate the Matthew Effect? Intellectual Property Rights and Access to International Alliances

Working Papers

We explore how intellectual property rights (IPR), a type of formal institution, affect firms’ access to global alliance networks and their positioning within those networks. We employed a difference-in-difference design to assess the impact of IPR reforms across thirteen countries.Read More

Becoming a Corporate Entrepreneur: Individual Specialization, Group Functional Diversity, and Corporate Venturing Within Firms

Working Papers

Many large firms try to encourage entrepreneurial initiatives by their employees, but the question of which employees undertake such initiatives has not been explored. In this study, we argue that the formal division of labor within a firm affects employees’ likelihood of engaging in internal corporate venturing. Read More

Optimal Network Design for Inducing Effort

Working Papers

Many companies create and manage communities where consumers observe and exchange information about the effort expended by other consumers. Such communities are especially popular in the areas of fitness, education, dieting, and financial savings. Read More

Network Externalities and Firm Innovation

Funded Research Proposal

We propose a novel theory of network externalities to explore the causal relationship between a firm’s position in an alliance network and its innovation outcomes. We posit that the network position a focal firm occupies can be unexpectedly and suddenly reshaped by the acquisitions of other firms. Read More

Small Worlds in Context: How Network Evolution and Performance Vary with Network Type

Funded Research Proposal

While much strategic management research examines network evolution through a micro-level focus on the dyads composing networks, far fewer studies have attempted to analyze network structure and evolution at the more macro level of aggregate networks. Read More

Women, Rails and Telegraphs: An Empirical Study of Information Diffusion and Collective Action

Working Papers

How do social interactions shape collective action, and how are they mediated by the availability of networked information technologies? To answer these questions, we study the Temperance Crusade, one of the earliest instances of organized political mobilization by women in the U.S. Read More

Competition–Cooperation Interplay during Multifirm Technology Coordination: The Effect of Firm Heterogeneity on Conflict and Consensus in a Technology Standards Organization

Published Research

We examine how competitive tensions and cooperative motivations together shape firms’ interactions and group‐level outcomes during technology coordination activities in multifirm settings. Read More

Skilled Immigration and Firm-Level Innovation: The U.S. H-1B Lottery

Working Papers

The growth of the global technology industry drives the migration of skilled labor towards countries like the United States that can utilize it, but the U.S. limits the immigration of skilled workers that are employed domestically by U.S. firms. Proponents argue skilled immigration allows firms to access technical skills that unavailable domestically and promote innovation, but there is little evidence of whether this firm-level effect exists.Read More

Multiplex Ties and the Diffusion of Complex Innovations: Evidence from a Microfinance Intervention

Working Papers

The networks literature examining the diffusion of complex innovations by social contagion has focused on the benefits of “multiplex” (or “wide”) ties in these processes. Multiplex ties span different types of networks to create inter-connectivity across subgraphs within a community. Read More

Networks and Innovation: Accounting for Structural and Institutional Sources of Recombination in Brokerage Triads

Published Research

Research linking interorganizational networks to innovation has focused on spanning structural boundaries as a means of knowledge recombination. Increasingly, firms also partner across institutional boundaries (countries, industries, technologies) in their search for new knowledge.Read More

Cascading Effects of Corporate Taxation in the Firm Network: Bonus Depreciation and Dividend Tax Cut Cases

Funded Research Proposal

Under the Trump administration, corporate tax policies have been recently attracting more and more attention. While there are papers studying direct effects of corporate tax, there is no research on indirect effects of corporate tax through the firm network. Read More

The Impact of Context and Model Choice on the Determinants of Strategic Alliance Formation: Evidence from a Staged Replication Study

Published Research

Endogenous characteristics of alliance network structure have repeatedly been shown to predict future alliance ties in the strategic management literature. Specifically, the concepts and measures of relational, structural, and positional embeddedness (per Gulati and Gargiulo, 1999), as well as interdependence, are foundational for many studies.Read More

Conflict, Cooperation, and Consensus in Standards-Setting

Funded Research Proposal

We study how firms simultaneously engage in competition and cooperation in technology standard-setting multipartner alliances. Departing from prior research that has typically explored competition in isolation from cooperation, we bridge these two literatures by examining firm communication and community consensus in these venues.Read More

The First Step to Successful Innovation? Choosing the Right Partners

Wharton management professor Exequiel Hernandez searches for the optimal mix of domestic and foreign partners in a firm’s network. The answer depends on what type of innovative solution a firm is trying to produce.Read More

Connecting Internal and External Networks of Cooperation: The North Star Alliance’s Roadside Wellness Centers Across Africa

Funded Research Proposal

This research project examines how organizations can develop innovative solutions to large-scale socio-economic problems in emerging markets through multi-stakeholder partnerships. The objective is to determine how these partnerships are built, what the optimal configuration of partners is, and how the partnerships should be coordinated.Read More

Competition, cooperation, and evolution in alliance networks

Funded Research Proposal

1) We examine the evolution of alliance networks by predicting ties and structure in the chemical and semiconductor industries. We compare our results to historical studies to determine how industry, timeframe, and method affect findings. 2) We explore the relationship between alliance networks and the locus of technological development which focuses on the standards-setting context.Read More
