Do blockchain capabilities help overcome supply and operational risks: Insights from firm market returns during COVID-19
Uncertainty and risk have become increasingly prominent issues in firm operating environments. Addressing uncertainties and risks brought by the historically disruptive COVID-19 pandemic crisis requires organizations to establish reliable, visible, and traceable information processing and sharing capabilities. Blockchain is a disruptive technology that can build capabilities to support operational resilience where uncertainty may manifest as risk or opportunity. Using an event study, we examine the COVID-19 pandemic relationship to stock returns for 217 blockchain-related firms—those that develop or apply blockchain technology—over five major pandemic life cycle periods. Our results indicate firms with blockchain capabilities have less mean negative stock price reaction—on average, a reduced 8.24 % shareholder value loss across crisis stages. Different blockchain application fields exhibit varied shareholder value effects—in general, production blockchain applications can help firms reduce more negative impact while financial blockchain applications show no significant mitigation effects. We further demonstrate how blockchain operational characteristics affect stock returns. Overall, blockchain technology provides effective risk buffer capabilities and can help manage shifting institutional fields—which the market views as building resilient capabilities resulting in competitive advantage to overcome known and unknown uncertainties and risks.
期刊介绍:
Omega reports on developments in management, including the latest research results and applications. Original contributions and review articles describe the state of the art in specific fields or functions of management, while there are shorter critical assessments of particular management techniques. Other features of the journal are the "Memoranda" section for short communications and "Feedback", a correspondence column. Omega is both stimulating reading and an important source for practising managers, specialists in management services, operational research workers and management scientists, management consultants, academics, students and research personnel throughout the world. The material published is of high quality and relevance, written in a manner which makes it accessible to all of this wide-ranging readership. Preference will be given to papers with implications to the practice of management. Submissions of purely theoretical papers are discouraged. The review of material for publication in the journal reflects this aim.
