Often, even great policy ideas show a lack of implementation because they require unrealistic resources such as financial but also human or infrastructural. This is why we suggest to incorporate into the research paper the potential costs of an implementation for different entities.
Example: The research argues that it would be important to enhance urban gardening in Swiss cities. Therefore, the research paper would give an idea of average costs per person for different cities (including infrastructure, trainings etc.).
We assume that policy makers might consider the idea as more relevant if they can see the actual financial impact and hence they might be more likely to implement the idea. Even more so, if the financial long-term benefits are mentioned as well.
