In recent years, information security has been gaining increasing public attention and has become a high priority for organizations across various industries. Despite the substantial investment in improving security posture, cyber risks continue to escalate as digital transformations are growing rapidly, and new areas of cyber-vulnerability are exposed and exploited. Thus, a critical question for managers, stakeholders, and policymakers is: How to strategically ensure the security of digital assets? To explore the question, my dissertation explores and advances three critical themes in the economics of the information security field. These themes include: 1) unraveling antecedents of risks, 2) determining the optimal level of investment in cybersecurity, and 3) investigating how cybersecurity affects market dynamics. Essay 1 is motivated by security concerns in sharing data across organizations and empirically evaluates the impact of joining a Health Information Exchange (HIE) initiative on a hospital’s data breach risks and corresponding mechanisms. Essay 2 uses a game theoretical model to investigate how to design a cost-effective crowdsourcing solution to help organizations leverage crowds’ wisdom in vulnerability management. Essay 3 examines the role of peer cyber incidents in information asymmetry issues in the financial market and analyze how peer data breaches affect the quality of a firm’s cyber risk disclosure in its financial report. The dissertation sheds light on three crucial factors in information security management: information systems interdependency, innovated cybersecurity solutions, and cyber information asymmetry. / Business Administration/Management Information Systems
