Abstract



In the research on influence strategies used in collective decision making in policy domains two main theoretical approaches can be distinguished: Conflict Resolution and Social Exchange theory. Until now these approaches are compared by comparing the predictions of two models of collective decision making which stem from these two approaches: the Expected Utility model of Bueno de Mesquita and the Exchange model of Stokman and Van Oosten.

However, this has lead to two problems. Although much effort is put in collecting data on collective decision-making situations, the available data sets are not yet sufficient to answer the question in which collective decision-making situations the difference in assumption on applied influence strategy lead to different predictions. Because of this, I propose to use simulated data for a more structured search.

Furthermore, since the Expected Utility model and the Exchange model differ in more respects than just applied influence strategy, it is questionable whether the differences in results stem from the difference in applied influence strategy. To study the effect of applied influence strategy, the Exchange model and Expected Utility model have to be modified in such a way that they only differ in this respect. These modifications lead to the Iterative Exchange model and the Challenge model, which are the models that will be compared.

A design for a structered search using simulated data is presented and the paper ends with some (preliminary) results.
