EcoEchoes

This episode’s guest is Karen Trujillo Jara, a PhD candidate in Health Economics at Erasmus University Rotterdam and a former EcoEchoes host. She discusses her research on patient-centred care in Peruvian hospitals, exploring how patients and healthcare professionals prioritise different aspects of care using Q-methodology. The conversation covers the importance of understanding patients’ perspectives, how these findings can inform healthcare practice and policy, and the value of combining quantitative and qualitative research. Karen also reflects on her experience conducting fieldwork in Peru, her PhD journey, and the importance of recognising small achievements along the way.Guest: Karen Trujillo Jara, PhD Candidate, Erasmus University RotterdamHosts: Andrea De Palma and Owen McWilliams

Karen and Fanny talk to Niek Mouter, Associate professor at Delft University of Technology and co-founder of the start-up Populytics. We talk about the birth of the participatory value evaluation (PVE), a method which elicits peoples' preferences over the allocation of budgets for different public policies. We discuss quite in detail how to design and conduct PVEs, and briefly go over a specific case study in Peru (which was joint work with Karen).

This episode’s guest is Jonathan Sicsic, Associate professor of Economics at Université Paris Cité. We first discuss his paper "Home over institution? New insights on older adults’ care preferences from a mixed-methods study in France" together with Anaïs Cheneau and Thomas Rapp. Secondly, we discuss how they have extended the survey and discrete choice experiment about long-term care to five other countries, and what research they intend to do next.

This episode’s guest is Pieter van Baal, Professor of Public Health Economics at the Erasmus School of Health Policy & Management and head of the Health Economics department. The conversation explores pharmaceutical pricing, patents, and innovation incentives, discussing why healthcare systems negotiate medicine prices and whether the current model for developing innovative medicines is functioning effectively. Pieter reflects on the role of governments, pharmaceutical companies, and public funding in medical innovation, while also considering alternative systems that could make medicines more accessible and affordable. The episode additionally touches on academic leadership, research culture, and advice for PhD students navigating academia.

This episode’s guest is Frédérique Franken, a PhD candidate at the Erasmus School of Health Policy & Management (ESHPM). She discusses her research on the environmental sustainability of healthcare, focusing on the role of insurer–provider contract negotiations in driving greener practices. The conversation explores how healthcare systems contribute to climate change, the Dutch policy context (including the Green Deal Sustainable Healthcare), and the challenges of translating sustainability goals into concrete actions. Frédérique also reflects on her interdisciplinary path from medicine to health economics and the practical realities of conducting mixed-methods research.

This episode’s guest is Elisa de Weerd, a PhD candidate in Health Economics at the Erasmus School of Economics and incoming postdoctoral researcher at Radboud University. She discusses her research on employment and earnings dynamics before and after transgender transitioning using Dutch administrative data. The conversation explores how large-scale administrative datasets can help study labor market inequalities faced by transgender individuals, the methodological challenges of identifying transitioning events in the data, and the implications for understanding economic outcomes and wellbeing. Elisa also reflects on how the project developed during her PhD and on future research directions.

This episode features Johannes Cordier, a visiting PhD student from the University of St. Gallen at Erasmus University Rotterdam.
Johannes discusses two papers using Swiss hospital administrative data. The first examines how machine learning methods can identify under-reported sepsis cases, shedding light on how coding practices and reimbursement incentives affect data quality. The second studies how patient placement across hospital wards influences mortality, combining causal machine learning with decision-theoretic approaches to account for capacity constraints.
The episode concludes with reflections on research visits, academic conferences, and practical advice for PhD students navigating research careers and industry pathways.

This episode’s guest is Sanna Azzouz, PhD candidate in Health Technology Assessment at Erasmus University Rotterdam. She discusses her paper "Cost-effectiveness analysis of image-guided ablation versus conventional ablation in patients with recurrent ventricular tachycardia in France: results from the inEurHeart trial".
The conversation covers how ventricular tachycardia develops after myocardial infarction, the clinical and economic trade-offs between different treatment options, and how AI-based imaging can reduce procedure time and costs without compromising patient outcomes. The episode also reflects on the challenges of measuring quality of life in severe cardiac conditions and translating short-term trial results into long-term health economic insights.
In the final part, Sanna shares her experience working at the intersection of healthcare, economics, and AI, and offers personal advice for PhD students on growth, balance, and enjoying the research journey.

In this episode, Stefan Lipman, Assistant Professor at Erasmus School of Health Policy & Management (Erasmus University Rotterdam), discusses with us how financial incentives can be used to promote healthy behaviour. The conversation covers incentive design (carrots vs. sticks), ethical and equity considerations, funding and cost-effectiveness, the role of structural determinants of health, and the sustainability of behaviour change. In the final part, he shares advice for PhD students and early-career researchers on teaching, presenting, and transitioning to a PhD in Health Economics coming from a different background.

In this episode, we have a casual chat about Prithvi’s experience attending and presenting at the International Long-Term Care Policy Network (ILPN) 2024 Conference in Bilbao. We talk about what the conference was like, from the city to the general vibe, and what it’s like to present research to a mixed audience. More broadly, we chat about navigating big conferences solo, tips for meeting people and starting conversations, and general observations about conference culture.
