Effects of a flat rate introduction: shifts in farm activity and impact on farmers' income

Marchand, Fleur L.; Buysse, Jeroen; Campens, V.; … - European Association of Agricultural Economists - EAAE - 2008

Current thoughts on CAP changes, e.g. the "Health Check", emphasize the necessity to move away from payments based on historical receipts towards a "flatter rate" system. The aim of current research is to simulate the impact of a flat rate system (equal payments per hectare of cultivated land)...
