Assistant Professor At The University Of Groningen

After being a Postdoctoral Researcher at the Department of Spatial Planning and Environment of the Faculty of Spatial Sciences at the University of Groningen for about 2,5 years, I am very happy to have been appointed Assistant Professor in Infrastructure Planning, Governance & Methodology (tenured) at the same department. I will contribute to the development of governance and methodological courses at the Faculty, supervise students in their thesis projects at the Bachelor, Master, and PhD levels, and aim to intensify the relationships between research and teaching. In doing so, I will continue to collaborate with governmental partners such as Rijkswaterstaat. More information can be found on the staff webpage of the university.

What Makes Decisions About Urban Water Infrastructure Forward Looking? A Fuzzy-Set Qualitative Comparative Analysis Of Investment Decisions In 40 Dutch Municipalities

Municipalities worldwide are confronted with the need to take long-term decisions about ageing water infrastructure in the face of unpredictable future developments. Previous studies on long-term decision making have proposed solutions targeted at the domain of either politics or planning. This study combines insights from the domains of policy, politics, and planning by using the Multiple Streams Framework to explain what enables municipalities to take forward-looking investment decisions. We combine the configurational MSF perspective with an explicitly configurational method, namely fuzzy-set qualitative comparative analysis, and apply this to 40 cases of Dutch municipalities. We conclude that enabling conditions differ for small versus medium-to-large municipalities. Furthermore, forward-looking investment decisions can be achieved regardless of the municipalities’ organizational analytical capacity. In fact, and contrasting to the requirement of the MSF, not all streams necessarily have to be present for forward-looking decisions to occur. For medium-to-large municipalities, forward-looking investment decisions are stimulated by: (1) the presence of organizational analytical capacity, (2) transactional/networking political leadership in situations without focusing events, or (3) entrepreneurial/transformative political leadership in situations with focusing events. For small municipalities, forward-looking investment decisions are stimulated by networking/interpersonal political leadership combined with the occurrence of focusing events.

Evaluating Infrastructure Project Planning And Implementation: A Study Using Qualitative Comparative Analysis

Many evaluations of infrastructure projects rely on methods that ignore the complexity of the projects. Although case studies are attentive to project complexity, it is difficult to identify general patterns that would apply to a larger sample of projects. Qualitative comparative analysis is a method that preserves the complexity of projects and generates insights across cases. In this contribution, we discuss our experiences with using qualitative comparative analysis for the evaluation of the planning and implementation of complex infrastructure projects. We will provide a short introduction into the main properties of the method (complex causality, systematic comparison) as well as describe some of the main operations (calibration, truth table analysis, interpretation). This will serve to demonstrate why qualitative comparative analysis is a fitting evaluation method in project development and implementation. Next, we will show how we used the method in a research project that aimed to find out under what conditions unplanned events in the implementation of infrastructure projects were dealt with satisfactorily, that is, what it took to respond to these events in an apt manner. Based on our experiences, we will summarize main lessons learned for conducting qualitative comparative analysis proper and provide suggestions for further reading.

Call For Papers: Case-Oriented & Set-Theoretic Approaches To Comparative Policy Analysis

Together with Eva Thomann and Valérie Pattyn, I invite you to submit a paper proposal for our panel Case-Oriented and Set-Theoretic Approaches to Comparative Policy Analysis at the International Conference on Public Policy (ICPP4) in Montreal, organized by the International Public Policy Association. The deadline for your paper proposal is January 30th, 2019. More information about the Call for Papers can be found here. If you have any questions about the call, please do not hesitate to contact me.

The policy process is characterized by a considerable degree of complexity regarding institutional settings, actor and preference constellations, policy goals, contents, and tools. Simultaneously, there is a practical demand for better knowledge of “what works” in public policies and under what conditions or in what contexts. In order to better match methods with theories and empirical realities, the analysis of public policies faces several challenging tasks (Brans & Pattyn, 2017). First, it needs to model the complexity that characterizes the policy process and trace the underlying mechanisms. Second, comparative policy analysis detects regularities and achieves a modest degree of generalization. Finally, comparative policy analysis often deals with small or intermediate numbers of cases.

Case-oriented and set-theoretic approaches to comparative policy analysis, such as Qualitative Comparative Analysis (QCA), Coincidence Analysis (CNA), explanatory typologies, and comparative process tracing, are designed to address these challenges. Situated within a “critical realist” paradigm of social research (Gerrits & Verweij, 2013), they model different aspects of causal complexity, such as configurations of different factors leading to policy outputs or outcomes, equifinality (multiple configurations can result in the same outcome), contextual contingencies, and causal asymmetry. Moreover, they can be applied within a variety of small-N or large-N research approaches to evaluate as well as generate theories through a combination of systematic comparison with targeted in-depth case studies (Thomann & Maggetti, 2017). As interactive and iterative methods, they also lend themselves to interpretative comparative analysis (Brans & Pattyn, 2017).

Set-theoretic and case-oriented methods are increasingly common in comparative policy analysis (see e.g., Rihoux et al., 2011; Thomann, 2019), particularly in policy implementation and evaluation research (Gerrits & Verweij, 2018; Pattyn et al., 2017). This panel gathers both theoretical, conceptual, and empirical contributions that deal with the state of the art of case-oriented and set-theoretic approaches and illustrate their potential and limitations to contribute to the theory and practice of policy analysis.

Meerwaarde Door PPS: Welke Meerwaarde?

Publiek-Private Samenwerking (PPS) in de transportinfrastructuur is populair vanuit het idee dat samenwerking meerwaarde zou opleveren voor de betrokken partijen. Sterker nog, het zou meerwaarde opleveren die anders niet bereikt kan worden. Maar de wens lijkt de vader van de gedachte. Het bewijs voor meerwaarde door samenwerking in PPS is schaars.
