Its main aim is to prove that this spread can be attributed to the workings of policy diffusion. Through a qualitative analysis of primary sources, such as municipal assembly minutes, the thesis establishes that the spread of this policy is indeed largely the result of an interdependence between local governments' policy choices. It explains this interdependence through a combination of the analytical frameworks of rational choice institutionalism and normative institutionalism. Both competition for status as well as the ability to learn from preceding governments' policies are found to have played a role. While the thesis does not find compelling evidence for the supposed role of regional proximity, its findings do suggest that core cities are more likely to be influenced by other core cities, and that designated cities are more likely to be influenced by other designated cities.Show less
