MacSharry Challenge: A Farm Simulation Study, The
用数学模型模拟了欧盟共同农业政策改革对意大利典型农场作物产量、轮作和耕作制度的影响，评估了专业和小规模生产者两种补贴方案，发现免耕虽能补偿收入但会降低产量。
A mathematical programming model is used to investigate the effects of the MacSharry Common Agricultural Policy (CAP) reform on crop yields, rotations, and tillage systems of a representative Italian farm. Both professional and small producer regimes are evaluated. The results of the simulation show the profound impact of the policy changes on farm income and land value. No-tillage is introduced to compensate for lower returns, with a strong reductive effect on crop yields. Overall, farm returns are maximized under the professional support regime.
