From Our Executive Director

Visibility Icon

Looking back on our 55th year, the Leonard Davis Institute of Health Economics remained strong and more relevant than ever. As Penn’s hub for research on population health, the health care system, and health policy, LDI continues to support, connect, engage, and amplify the research of over 400 Senior Fellows from across Penn’s campus. We have invested in the talents and visibility of our faculty to increase their reach and impact, built new research partnerships and learning laboratories that will enable faculty to do high-impact and timely work to address critical challenges in health policy, and led important evidence-informed conversations to advance health policy.

In this Year in Review, I hope that you will enjoy revisiting work that was impactful to you and discovering new things that you may have missed. I am proud of everything that we achieved in 2022 and I look forward building on this year’s work to further advance our priorities in 2023.

How a Federal Policy for Pharmacoequity Keeps Falling Short

The 340B program requires pharmaceutical companies to provide steep drug discounts to eligible safety net hospitals and clinics.

Jalpa Doshi and colleagues examined the effects of this program on availability of pharmacies, finding that while the total number of 340B pharmacies increased, pharmacies in disadvantaged neighborhoods decreased. 


Penn LDI hosted a full schedule of events in 2022. Our virtual policy seminars reached a wide, interdisciplinary, national audience of thousands, and were supplemented by in-person seminars, workshops, and events. In total we hosted over 25 events in 2022 on campus, online, and in Washington, D.C. See recaps of selected events below.

Featured Partnership: Penn LDI Research Initiative on Improving Management of Chronic Kidney Disease

Penn LDI launched a new initiative to support research to transform health care delivery for patients with chronic kidney disease (CKD). The Penn LDI Research Initiative on Improving Management of Chronic Kidney Disease will fund rapid-turnaround high-impact research projects that will have a meaningful and measurable impact on improving the delivery of care for individuals with CKD, with a particular focus on projects that addresses disparities in care, including structural barriers and racial inequities. We anticipate funding up to five research projects of up to $350,000 each over three years (through two Requests for Proposals). This program is made possible by a generous gift from Monogram Health.
