To which extent are counter-cyclical payments more distorting than single farm payments? Evidence from a farm household model
比较了反周期支付和单一农场支付对农场生产决策的影响，发现反周期支付更具扭曲性，但扭曲程度小于WTO谈判中假设的差异。
The distinction between single farm payments (SFP) and counter-cyclical payments (CCPs) is mainly based on theory. Due to a lack of empirical comparative studies between these payments, it is difficult to confirm the claim that CCPs are more distorting. This paper provides a comparative analysis of these payments and quantifies the impact of such payments in the presence of debt constraints. The main findings are that CCPs are more distorting than SFP. However, the magnitude of the impact estimates is not as large as suggested by the different treatment received by both support programmes in the WTO negotiations.
