IHEA has three awards:

  • The Adam Wagstaff Award for Outstanding Research on the Economics of Healthcare Financing and Delivery in Low- and Middle-Income Countries;
  • The Arrow Award for the best published health economics paper; and
  • The Student Paper Prize for the best paper by a Masters or Doctoral student.

Adam Wagstaff

3 May 1959 – 10 May 2020
IHEA President 2016 – 2017

This award was established by colleagues and friends in memory of Adam Wagstaff and was funded through ‘Friends of Adam’ crowdfunding. The prize is awarded to the best IHEA congress paper on the economics of healthcare financing or delivery in a low- or middle-income country(ies) (LMIC) that is written and presented by a researcher from a LMIC. It reflects Adam’s lifelong commitment to these issues and to promoting equity in LMICs.

About the Adam Wagstaff Award

  • This award is intended for early career researchers (ECRs)/recent graduates, not those currently studying. Students are encouraged to submit an entry for the annual IHEA Student Paper Prize.
  • To be considered for the Adam Wagstaff Award, the ECR must have an abstract accepted for oral presentation at the IHEA congress. You must indicate your interest in being considered for this award during the abstract submission process.
  • The paper must focus on the economics of healthcare financing or delivery in a LMIC (this can include a country defined by the World Bank as a middle-income country until not more than a year ago, that is now classified as a high-income country). The research should be policy-relevant in that it should provide insights into how to improve healthcare financing or delivery. Papers with an equity focus are encouraged.
  • The first author of the paper (or corresponding author where authors are listed alphabetically) and presenter at the congress must be a citizen of a LMIC (using the World Bank country income classification). Co-authors on the paper are not restricted to LMIC citizens.
  • The main author and presenter at the congress must have submitted their doctorate or have completed their doctorate within the last 7 full-time equivalent years.
  • To be considered for the award, a full paper must be available three months before the congress and be submitted with a personal statement of 500 words outlining your future career plans at the time of application.
  • Submitters should be willing to commit to contributing to health economics in LMICs if they win this award. This could take the form of mentoring researchers with very limited experience, co-supervising a (post-)graduate student, serving on the Award Committee in future, or related activity, depending on the skills and preferences of the Awardee.

Can I submit a paper that analyses global data, so includes low-, middle- and high-income countries?  No, only papers that have a specific focus on LMICs will be considered.

Can a paper that considers theoretical or methodological issues be submitted?  Usually not, unless there is a very specific focus on LMICs (e.g. development of an innovative methodology for health care financing or delivery research to address data constraints in LMICs).

Can an economic evaluation paper be submitted?  Generally not. As the focus of the award is on the economics of health care financing or delivery, only economic evaluations that compare alternative service delivery options and/or include a budget impact analysis of services that address a major burden of disease in LMICs will be considered. Papers that focus purely on the effectiveness of health care interventions or an economic evaluation of a very specific clinical intervention are not eligible.

If I graduated 8 or 9 years ago, but had maternity leave and worked part-time for a year afterwards, will my paper be considered?  Yes, as long as the full-time equivalent working period after graduation is no longer than 7 years at the time of application.

If I am a citizen of a LMIC, but am currently living and working in a high-income country, will my paper be considered?  Yes, as long as the paper focuses on LMICs and your intention is to continue undertaking research focused on LMICs.

Those from a low- or middle-income country with an accepted abstract, on the economics of healthcare financing or delivery in a LMIC, for the next IHEA congress will be invited to submit a full paper for review by the selection committee three months prior to the congress. The selection criteria are comparable to those used for the Arrow Award and the Student Prize, which focus on the importance of the contribution of the paper and appropriateness and innovation in methodology.

The award includes a certificate and a cash prize, which will be presented during one of the plenary sessions of the congress. The session in which the award-winning paper is presented will be highlighted as a special session and the presentation will be followed by discussant input. In addition, the winner will be invited to present at the World Bank’s Health Finance Forum.

Lucy Xiaolu Wang

Procurement Institutions and Essential Drug Supply in Low- and Middle-Income Countries

Lucy Xiaolu Wang is a tenure-track Assistant Professor at the University of Massachusetts Amherst, a Faculty Research Fellow at the Max Planck Institute for Innovation and Competition, Germany, and a Faculty Associate at the Canadian Centre for Health Economics. Her research focuses on the economics of innovation & digitization in health care markets (national and global), particularly in the biotech, pharmaceutical, and digital health industries. Dr. Wang earned her Ph.D. in economics at Cornell University, her M.A. in economics at Duke University, and her B.A. in economics (specialty: insurance) at Central University of Finance and Economics in China.

As an early career scholar who originated from a small city in China, Dr. Wang aims to better understand and improve healthcare financing, delivery, technological innovation, and access in LMIC (Low and Middle-Income Countries/Country). Specifically, she works on two lines of research centering on LMIC healthcare.

First, the performance of novel institutions in improving healthcare financing and delivery. Dr. Wang has published work and ongoing projects examining the effectiveness of the Medicines Patent Pool as a joint licensing organization in facilitating generic drug diffusion and spillover effects on upstream innovation. She also investigates the role of procurement institutions and essential drug supply in LMIC with a complementary analytical angle.

Second, Dr. Wang studies health care technological innovation and digitization. Dr. Wang has ongoing research projects on digital interventions in the health sectors with LMIC country cases and policy discussions. She also works on understanding the current drug patent reforms in China.

Members of the initial Award Committee were selected to include at least one close colleague of Adam's from long-term collaborative research projects; at least one of Adam's colleagues from the World Bank with expertise in this sub-field; and at least one researcher with expertise in the sub-field who is based in or affiliated with a LMIC institution. The Committee members, in alphabetical order, are:

Kenneth J. Arrow

23 August 1921 – 21 February 2017

This annual award was established in honor of Kenneth Arrow and in recognition of the influence of his seminal paper from 1963 “Uncertainty and the welfare economics of medical care”. It recognizes excellence in the field of health economics, with the award presented to the author(s) of the paper judged to be the best paper published in health economics in English in the award year.

About the Arrow Award

Deadline: Annually in January

IHEA’s Arrow Award was created to recognize excellence in the field of health economics with the Award presented to the author or authors of the paper judged to be the best paper published in health economics in English in the award year. The Award was set up in honour of the late Kenneth Arrow and in recognition of the influence of his seminal paper from 1963 “Uncertainty and the welfare economics of medical care”. Professor Arrow was involved in the creation of the Award and he presented the inaugural prize in 1993.  

The Award is made every year. Each year the Award committee considers a short-list of up to ten papers, with each paper evaluated by all of the committee members in terms of importance and originality of contribution, appropriateness and innovation in methodology and clarity of presentation. You can view the most recent award winners here.  

Nominations for the Arrow Award from members of IHEA are welcome and should be sent to the Chair of the Committee (Tor Iversen:, accompanied by a copy of the paper and a brief cover letter.

The Arrow Award Committee proudly recognizes the authors of this innovative paper, which uses machine learning to study decision making in healthcare. The authors focus on how physicians diagnose heart attack. Using an algorithmic model to predict a patient’s probability of experiencing a heart attack, the authors identify instances where a physician’s testing decisions deviate from the predicted risk. 

The study reveals that physicians both undertest and overtest. From a natural experiment they find that inefficiencies cannot be explained by incentives alone and point to systematic errors in judgement. The authors find that physicians tend to use a simplistic risk model and overweight factors that are salient or representative of heart attack, such as chest pain. The authors argue that health care models should account for physician error, as focusing solely on incentives can produce large inefficiencies. The conclusion has broad implications for understanding physician decision-making and modeling physician behavior in health economics research. 

We congratulate the authors on the publication of this important paper.

Yashaswini Singh

Johns Hopkins University
“Can Private Equity Buy Referrals? Evidence from Multispecialty Physician Practice Acquisitions”

Multispecialty physician practices (MSP) incentivize referrals from generalists to specialists within the same practice.  This research found that private Equity (PE) acquisitions of MSP increase referrals within the practice, largely due to the adoption of PE’s managerial strategies.  It also explored the implications for patient welfare.

Honorable mentions go to the two runners up

Vera Zabrodina

“Timing Moral Hazard under Deductibles in Health Insurance”

The paper develops a novel approach to examine the extent to which individuals strategically time their healthcare consumption under deductibles in health insurance. 

Benedikt Janzen

“Temperature and Mental Health: Evidence from Helpline Calls”

This paper examined the negative effect of temperature extremes on mental health, reflected in an increase in the demand for telephone counselling services in Germany.

The prize winners are expected to present their papers at a special session of the 2023 IHEA Congress in Cape Town. Many thanks to all those who submitted papers for consideration, and to the Prize Committee for all their hard work.
