Abstract
This dissertation aims to empirically study the business and societal consequences arising from the usage of emerging information technologies. The first chapter examines the unintended spillover effects of health information technology (HIT) integration in combating the opioid crisis. I find that for a focal county, its neighboring state’s integrating Prescription Drug Monitoring Program (PDMP) into local Electronic Health Records (EHR) leads to an increase in the focal county’s consumption of prescribed opioids, an undesirable spillover effect. Moreover, this undesirable spillover effect is mitigated when prescribers in the focal county have access to the neighboring state’s PDMP data via interstate PDMP data sharing. In the second chapter, I explore the effect of opting out of cookie tracking on consumer behavior on a news website. I find that consumers increase the quantity and diversity of their news consumption after disabling cookie tracking. This effect could be attributed to consumers' intrinsic value of enhanced privacy control. The results imply that protecting consumer privacy can add business value to firms.
