The aim of the project is to analyze, within a comparative institutionalist analytical framework, the trajectories of socio-economic development models. Comparative analyses of forms of capitalism have underlined the diversity in institutional configurations. Within the EU, it is assumed that four types of socio-economic models exist: market-oriented, continental, Nordic, and Southern, with the position of transitional CEEC under discussion. The project will reconstitute the historical trajectories of these socio-economic models, in order to understand how their institutional configuration mediates the synergies and tradeoffs between the economic, social and environmental dimensions of development.
