Friday Afternoon Workshop

The Friday Afternoon Workshops offer an opportunity for faculty and students to enjoy academic research presentations by scholars from around the world in their areas of expertise. Papers being presented are available for review prior to the workshop on our web site.

Following most workshop events, the Barstool Economists group meets at a local eatery, where the discussions with the speaker can be continued in a less formal environment. The workshops are open to all SJSU students, Faculty and invited guests.

"Public Reporting and Self-Regulation: Hospital Compare’s Effect on Brain and Sinus Computed Tomography Utilization" (co-author Danny R. Hughes)

Presentation Slides (pdf)

In an effort to reduce inappropriate and unnecessary medical imaging, provisions under the Affordable Care Act (ACA) led the Centers for Medicare and Medicaid Services to establish six outpatient imaging efficiency metrics (IEM) that would be publicly reported on Hospital Compare. However, there are no explicit benchmarks, financial incentives, or penalties associated with the IEM metrics. Complicating this form of regulation, the incentives of ordering physicians may not always be aligned with those of hospitals. Together, these issues raise questions regarding the efficacy of this kind of self-regulation to curb inappropriate care. We develop a model describing both hospital and physician behavior in response to this regulation. Using this framework, we employ a logistic difference-in-difference regression to test whether introducing IEMs were associated with reductions in imaging utilization. We focus on OP-14 which reports rates of same day brain and sinus computed tomography (CT). Preliminary results indicate that OP-14 was associated with a small but significant change in the rate of same day brain and sinus CT orders. However, when hospitals were separated into high-utilization and low-utilization groups, we found a large increase in same day brain and sinus CT orders for the low-utilization group. These preliminary results were qualitatively similar after testing other model specifications such as controlling for same day brain and sinus CTs in hospital emergency departments, which are responsible for much of the growth in CT utilization over time.

Darwyyn Deyo is an Assistant Professor of Economics at San Jose State University who teaches law and economics and labor economics. She has researched the impact of occupational licensing on service quality, the labor supply of criminals, and topics in health economics such as the impact of tort reform and the Affordable Care Act on health care utilization.
She earned a Doctorate in Economics and a Masters in Economics from George Mason University. She is also an alumni of Saint Mary’s College of California where she earned a dual Bachelor of Science in Economics and a Bachelor of Arts in International Area Studies. She has also worked as a Research Fellow with the Harvey L. Neiman Health Policy Institute and was an affiliate scholar with the Center for Micro-Economic Policy Research at George Mason University. Before beginning her doctorate, she worked as a journalist covering political news out of Pennsylvania.
Dr. Deyo is a California native and also enjoys competitive highland dancing and reading science fiction.

Liam Rose

Ph.D. candidate, UC Santa Cruz
Abstract: Liam's research paper utilizes census records, multiple comprehensive surveys, and mortality records from England to trace out the effect of reaching retirement age on retirement status, health behaviors, health care utilization, and health outcomes. Applying a regression discontinuity design leveraging the pension age, I find that retirement substantially improves well-being and satisfaction with health, along with fewer individuals reporting having health issues. However, I find no immediate effect of retirement on behavioral outcomes such as smoking or exercising, and no evidence of changes to cognitive ability or healthcare utilization. Finally, death certificate data indicate that retirement does not affect mortality. While prior literature have considered the effects of retirement on specific outcomes, this paper is the first to systematically examine the full range of health-related outcomes with administrative and survey data in a unified context.
