An Inside Look: Modeling Heterogeneity in the Organization of Scientific Work

Co-author(s): Hazhir Rahmandad (MIT)

Under second review in Organization Science, 2018

Although academic scientists work under similar institutions, norms, and incentives, they vary greatly in how they organize their research efforts and in their outputs. To understand this heterogeneity, we model scientists as publication-maximizing agents and identify two distinct organization patterns that are optimum under different parameters. When the net productivity of a research staff (e.g., PhD students and postdocs) is positive, the funded research model with an entrepreneurial scientist and a large team dominates. When the research staff’s costs exceed its productivity benefits, the hands-on research approach is optimal. Our model provides an explanatory framework for significant heterogeneity of scientists across fields in research funding, supply of scientific workforce, team size, publication output, perceived relevance gap, and stratification patterns over time. Exploratory empirical analysis finds… Read more

Topic Modeling: Method, Theory, and Application in Management Research

Co-author(s): Dev Jennings (UAlberta), Sarah Kaplan (UofT), Tim Hannigan (UAlberta), Richard Haans (Rotterdam), Vern Glaser (UAlberta), and Milo Wang (UAlberta)

Proposal accepted at Academy of Management Annals, 2018

The paper will start with a brief review of the methodological and theoretical foundations of topic modeling in content and classification analysis (e.g., Weber, 1990), along the way touching on specific issues, such as establishing corpora and their boundaries, pre-processing textual materials, and applying particular interpretive schemes. We will then focus on how topic modeling has shaped theorizing in management. We will examine subject areas where topic modeling has been applied that are relevant to management theory and some of the derived insights for the management field. Our review will finish with new directions in topic modeling research, both methodological (such as new forms of categorization and natural language processing), and theoretical (such as the application of topic models in the political analysis of organizations and interpretive schemes generated by organizational micro-processes)… Read more

Organizing for Innovation: A Contingency Perspective on Innovative Team Composition

Co-author(s): Sarah Kaplan (UofT)

R&R in Strategic Management Journal, 2018

While innovation has increasingly become a collaborative effort, we do not have a consensus about what types of team configurations might be the most useful for creating innovative outputs. Do teams need to include inventors with knowledge breadth or do they need inventors with deep expertise? Do teams need overlapping knowledge to integrate insights from diverse areas or does this redundancy get in the way of innovation? In this paper, we address these tensions by … Read more
