This paper responds to the ongoing debate on the improvement of the investment support in the CAP after 2020. First, the analysis of the sector performance of the past investment supports is presented, followed by the farm level dynamic counterfactual analysis of policy results. Baseline and three alternative scenarios of distributions between income and investment support are presented as they were agreed and assessed by experts and stakeholders in two focus groups. Apart from the significant effect on the expansion of livestock production, the impacts of the modernization support (M121) on farm performance are ambiguous. Participants of the focus groups will prefer maintaining the income support at the current level while reducing the intervention stimulating farms investment activity arguing by easier adjustment of activities to the actual needs of the business.
