This report presents a synthesis of the workshop, summarising the presentations and discussions in the different sessions. The report is organized following the structure of the workshop. The first session of the workshop sets the scene and introduces the main topic at stake. The second session aims at providing current studies estimating the impacts of Pillar 2 measures on agricultural productivity and other main factors (e.g., growth, employment). The third session provides an overview of existing modelling approaches, general and partial equilibrium, to simulate effects of shocks in Pillar 2 payments on the EU agricultural sector. Finally, the fourth session concludes and draws some key messages on how the JRC shall proceed in future efforts on the topic.
