According to the common sense, experts, backed up by scientific methods, describe the “possible states of the world” in a value-neutral way. Then, in the political arena, delegates build on these proposals, but also consider values and interests. The present paper attempts to revise such an understanding of local economic development (LED) and argues that many of the deficiencies deriving from such a view can be remedied by deliberative participation, which is not merely a theoretical necessity, but also a practical possibility.With regard to the issue of public participation and deliberation, the paper identifies two main approaches in the LED literature: the “political” and the “apolitical”, of which the latter is mainly characterised by economic theorising. We take a closer look at the “apolitical” approach and demonstrate that in fact it is very much political. Therefore, we call for the transgression of the borderline between politics and expertise in LED, and suggest a joint democratisation of these interrelated terrains. We argue that deliberative participation is able to contribute to the quality of both the expert proposals and the working of the politics.
