PhD Cross- collaboration care

Your function

Population ageing is rapidly increasing the demand for long-term care (LTC) while labor supply is shrinking, and public expenditure is under growing pressure from pay-as-you-go pension payments. This applies across most high- and middle-income countries over the next two decades, and possibly beyond, given declining birth rates and societal reluctance to increase immigration from low-income countries.

In response, OECD countries have introduced a range of governance and financing arrangements to address barriers such as the wrong-pocket problem. These arrangements rely on horizontal coordination, meaning collaboration across sectors and stakeholders, and vertical coordination, meaning alignment across levels of government and financing arrangements. Together, these policy options aim to reduce barriers to collaboration across organizational and financial boundaries.

In the Netherlands, cross-domain collaboration in LTC was structurally embedded in legislation in 2026, opening up new opportunities to refine existing approaches and address long-standing barriers around governance complexity and cost-shifting. Building on this, more than 50 neighborhood initiatives have been launched, in which municipalities, health insurers, and care providers jointly organize and finance support for frail older adults.

The DOS PROJECT examines these initiatives along two lines. First, it develops a set of time-series models that provide timely insight into neighborhood-level future trends in care use and costs, enabling earlier responses to emerging developments. Second, it evaluates the impact of the DOS initiatives at both the neighborhood and aggregate level. The PhD candidate will dive into rich, nationwide administrative data and run advanced level causal analyses to find out how DOS initiatives actually shape people's care behavior and health outcomes.

To identify broader trends and patterns at higher levels of aggregation, the project will apply hierarchical regression models with shrinkage.

The DOS research project is conducted by the Vrije Universiteit Amsterdam (VU) and is funded by Zorgverzekeraars Nederland. The PhD candidate will be employed at the department of Ethics, Governance & Society of the School of Business and Economics and supervised by prof. dr. X. Koolman in collaboration with dr.

F. R. Portrait, dr. N. Stadhouders and dr. Y. Krabbe, the project leader.

Your duties include:

• Conduct high-quality doctoral research leading to scientific journal articles and a PhD dissertation.
• Develop now casting models, matching models, hierarchical regression models to evaluate the DOS initiatives.
• Present your work at scientific conferences and workshops with academic partners and stakeholders such as Zorgverzekeraars Nederland, the Ministry of Health, Welfare and Sport, care offices, municipalities and care providers.
• Contribute to the teaching activities of the department, including lectures, tutorials, exams and grading.

• A research master’s degree in Economics, Health Sciences, PPE or a closely related field
• Interest in health care and health care-related policy subjects
• Programming skills in R.
• Strong analytical writing skills and the ability to present research results to policymakers.
• Excellent command of English in both speaking and writing.
• Dutch language skills (spoken and written) are an advantage.

A challenging position in a socially engaged organisation. At VU Amsterdam, you contribute to education, research and service for a better world. And that is valuable. So in return for your efforts, we offer you:

• A salary of €3,059.00 (PhD) and maximum €3,881.00 (PhD) gross per month in the fourth year, for a full-time employment
• An employment contract of initially 1 year. If there is sufficient perspective, this will be extended to a total of 3 years.

We also offer you attractive fringe benefits and arrangements. Some examples:
