In my dissertation, I study unintended consequences of the adoption of EMR systems. In my three essays, I examine how the adoption of EMR systems affects neighboring hospitals (spillover effects), can be used by hospitals to further its objectives in an unconventional manner ("upcoding" of patient case mix data), and how EMR adoption may…

Youth with autism spectrum disorder often have complex medical needs. Disruptions of healthcare during the transition from pediatric to adult healthcare may put youth with autism spectrum disorder at higher risk of medical emergencies and high medical costs.

The objective of this research is to understand how a set of systems, as defined by the business process, creates value. The three studies contained in this work develop the model of process-based automation. The model states that complementarities among systems are specified by handoffs in the business process. The model also provides theory to…
