Analysing Farm‐specific Payments for Norway using the Agrispace Model
研究利用新开发的Agrispace模型，模拟挪威当前和替代补贴政策对生产、价格、收入及农场结构变化的影响，发现短期政策支持了全国各类农场的维持，但长期结构变化受总补贴水平不变的政策改革影响较小。
Abstract Norway maintains a complex system of activity or type specific coupled payments which account for a large share of farm income. Most of the payment rates are negatively related to farm size and are higher in remote areas compared to central regions. We present and use a newly developed recursive‐dynamic multi‐commodity model (Agrispace) with CES production functions depicting regional farm clusters derived from the full farm population. Using this model, we simulate impacts of current and alternative subsidy policies on production, prices, input use, income and farm structural change. Mapping cluster results to each farm along with behavioural rules allows estimation of individual profits and farm exits. Our results indicate that, in the short run, the current policy regime seems to support the policy objective of maintaining a variety of farms in all parts of Norway. In the long run, farm structural change is less affected by a policy reform that leaves total support levels unchanged.
