    Abstract: This study explores how new text analysis tools can be used in strategy research that examines unstructured textual data. We build on two established Natural Language Processing (NLP) techniques, vector space models and topic modeling, to create text-based measures of several core strategy constructs – strategic change, positioning, and focus. These techniques are applied to 52,392 business descriptions in 10-K annual reports filed from 1996 to 2017. Our analysis shows that these new methods produce novel measures of strategy, opening up previously unexplored avenues of research to strategy scholars. The study advances emerging research utilizing text analysis, demonstrates that NLP techniques can overcome some limitations of traditional text analysis methods, and provides a template for how other machine learning techniques could be introduced into strategy.

    Description: Revise and Resubmit at the Strategic Management Journal.

  • MGMT101 - INTRO TO MANAGEMENT

    We all spend much of our lives in organizations. Most of us are born in organizations, educated in organizations, and work in organizations. Organizations emerge because individuals can't (or don't want to) accomplish their goals alone. Management is the art and science of helping individuals achieve their goals together. Managers in an organization determine where their organization is going and how it gets there. More formally, managers formulate strategies and implement those strategies. This course provides a framework for understanding the opportunities and challenges involved in formulating and implementing strategies by taking a "system" view of organizations,which means that we examine multiple aspects of how managers address their environments, strategy, structure, culture, tasks, people, and outputs, and how managerial decisions made in these various domains interrelate. The course will help you to understand and analyze how managers can formulate and implement strategies effectively. It will be particularly valuable if you are interested in management consulting, investment analysis, or entrepreneurship - but it will help you to better understand and be a more effective contributor to any organizations you join, whether they are large, established firms or startups. This course must be taken for a grade.
