This episode’s guest is Danae Arroyos-Calvera, Associate Professor in Behavioural and Experimental Economics at the University of Birmingham. She discusses her research on cooperation, moral wiggle room, and plausible deniability in public goods games. The conversation explores the challenge of translating lab findings to policy, the importance of publishing null results, and the balance between image, incentives, and fairness in human behaviour.

In this episode, Yubraj Acharya discusses his paper ‘Reducing Non-Prescription Antibiotics Use through Community Education in Low-Income Countries’. He sheds light on the growing issue of antimicrobial resistance (AMR) and shares about the intervention he conducted in Nepal, aimed at reducing non-prescribed antibiotic use among parents of children.

In this episode, Judith Bom and Gaia Bagnasco discuss their latest paper mapping care pathways for people in their last 6 years before death with dementia in the Netherlands. You can find the paper here. First, we talk about why studying ageing and dementia matters and how the Dutch long-term care system works. We then move on to discuss what their latent class analysis reveals about three distinct care trajectories: the late formal care group, the mixed care group and the early nursing home group. We also talk about the important roles of informal care, income, gender and the home environment in predicting these pathways. Finally, we discuss their upcoming research on dementia-friendly housing and cross-country comparisons.

Guest: Judith Bom (Assistant professor) and Gaia Bagnasco (PhD), both in health economics at the Erasmus School of Health Policy & Management

This episode’s guest is Anna Stirner, a PhD Candidate in Health Economics at the University of Cologne. She discusses her experimental study on physicians’ use of therapeutic decision support (DS) systems in pediatric antibiotic prescribing, examining how access, effort costs, and quality incentives shape uptake and care quality. The conversation explores the challenge of antibiotic overprescription, how younger versus more experienced physicians respond to DS, and policy implications for integrating DS into clinical practice. At the end, Anna also shares her next research steps and gives advice to PhD students.

Episode Description

This episode’s guest is Vahid, a Postdoctoral Researcher at the Erasmus School of Economics. His work is focused on the intersection between labor and health economics. In this episode, he presents his working paper on childhood mental health effects of early life exposure to paternal job loss. The discussion sheds light on a critical aspect of job loss and how this scenario can hit harder on families by emotional and psychological challenges.

This episode’s guest is Professor Hans van Kippersluis from Erasmus School of Economics. He discusses his working paper “Skipping your workout, again? Measuring and understanding time inconsistency in physical activity”, co-authored with Diarmaid Ó Ceallaigh and Kirsten Rohde. The paper studies time inconsistency in physical activity using survey data from the Dutch Lifelines cohort. They find that participants not only overestimate but also underestimate their future exercise. We talk about why present bias may not be the only explanation for the misalignment between intentions and behaviour, and how it may not be a stable personality trait. Hans also explains the use of choice matching to incentivise honest survey responses. Finally, we discuss how to write well-structured papers, the use of econometric methods for causal inference, and how Hans keeps up with developments in the econometrics literature.

This episode’s guest is Amal Ahmad, an Assistent Professor at the Development Economics group at Wageningen University. She presents her working paper on the effect of early mother's marriage on child growth in India. The authors explore this causal relationship using age at menarche as an instrumental variable. The conversation discusses the data and methods used, as well as policy implications and their political feasibility in the Indian context.

This episode's guest is Michael Haylock, a health economist now working in consulting after a postdoc at the University of Duisburg-Essen. He presents his paper “Improving the availability of stem cell donors,  a letter and email intervention” which looks at the effects of a behavioural intervention to reduce attrition among registered donors. We talk about the importance and logistics of stem cell donation, how commitment nudges can help identify more reliable donors, and the challenges of working with large registries. Michael also discusses a second paper on pro-social workplace behaviour, showing how leadership and personality shape helping cultures. The working paper is titled "Helping in the Workplace: The Role of Leadership and Employee Personality and Preferences". The episode ends with reflections on PhD life advice and transitioning to consultancy.

This episode’s guest is Benjamin Chibuye, a Postdoctoral Researcher at the Danish Centre for Health Economics (DaCHE) in Department of Public Health at the University of Southern Denmark. He presents his working paper on physician altruism and opioid prescribing, focusing on how Danish general practitioners respond to national guidelines in light of their professional motivations. The conversation explores the complexities of health provider behaviour, the role of public service motivation, and the broader policy implications for addressing opioid overuse.

This one is for the experimental economists. Fanny shares her experience attending the Economic Science Association’s European Meeting in Helsinki in September 2024. This was Fanny's first experience attending a non-health conference. Listen to find out why the conference is worth attending if you run experiments. The next European meeting will take place in Brno, Czech Republic from Wednesday 3 September until Saturday 6 September 2025. Find out more about the conference by clicking this link. Deadline for submitting an abstract is 5th May. 

Also, this episode was recorded back in October 2024, which is before we had a proper studio. Therefore, this episode has rougher audio than in our latest episodes. Thanks for your patience with the sound quality!
