Brief summary of my research over the last five years

The emphasis of my research has been on developing theoretical and mathematical models of cooperation problems, deriving model predictions, and testing these in the laboratory. These models deal with crucial aspects of collective action problems, and include prisoners’ dilemmas and public goods.

Together with my colleagues, I have built theoretical models to understand various aspects of cooperation and coordination problems, such as cooperation on social networks (Dijkstra and van Assen 2013), cooperation driven by heuristic decision making and norms (Dijkstra 2012), and the dependence of cooperative behavior on beliefs (Dijkstra and Oude Mulders 2014). Experimentally, we have tested theoretical models of cooperation in the context of inter-group conflict and externalities (Dijkstra 2013, Mäs and Dijkstra 2014, van der Iest, Dijkstra, and Stokman 2011). Moreover, we have experimentally tested the step-level public good model developed in Dijkstra and Oude Mulders (Dijkstra and Bakker 2017). Recently, we have developed a statistical method for directly testing micro-macro mechanisms with micro-level data (Dijkstra et al., 2019).

In collaboration with Rafael Wittek, Frans Stokman and my PhD student Timo Septer, I have investigated interpersonal conflict, using a cognitive mapping approach to elicit beliefs people hold about cause–effect relations concerning organizational changes.

In recent years I have built up a lot of expertise on the analysis collective action problems. Together with Andreas Flache I supervise ongoing experimental work on the effects of normative ambiguity on cooperation (with PhD student Dieko Bakker), and observational work on the success of energy neutrality initiatives (with PhD student Fleur Goedkoop).
