Sabbatical Sandra Rousseau: Economic modeling of alternative business models for a circular transition

In terms of content, my research would focus on the economic modeling of the circular transition.
Together with Prof. Arguedas and Prof. André, I would like to take the time to discuss our theoretical work on the welfare implications of the presence of a (secondary) sub-market next to a (primary)
developing the product market. We are currently working on the first publication on this subject and we have already identified many questions for further research that we would like to collaborate on. These research questions are, among others, 1) can we use the presence of network externalities to model the frictions in the submarket endogenously?, 2) how does the behavior of economic agents change if the supply on the submarket does not change from the
households only comes from the provider on the primary market?, or 3) are our insights preserved if we use dynamic instead of a static model?.
In addition, together with Prof. Arguedas investigate how the type of organization – for profit, non-profit versus social enterprise – and the associated differences in objective function influence the strategic behavior of these organizations. Specifically, we want to examine how these types of organizations make decisions about their environmental impact and compliance with environmental regulations. This model will allow us to advise on the adjustments that may be needed to enforcement policy in response to these societal changes.
Finally, I would also like to thank the collaboration with Prof. Taking Earnhart back to look at the different elements of the circular transition from an American perspective. This would be a first exploration to determine which elements are interesting for further research.
