The effect of changes in prices and quotas: An example of the use of an agricultural sector model based on the Johansen Approach
利用基于Johansen方法的农业部门模型，计算了价格和配额变化对农业收入和生产的影响，并预测了1982-1987年农业发展趋势。
The consequences for agricultural income and production of price and quota changes are calculated using an agricultural sector model for the Ee as a whole. The model uses the Johansen solution method which makes it possible to avoid making unrealistic separability assumptions between inputs and outputs. The model is used to calculate the lump sum payment and the decrease in the milk price which corresponds to a reduction in the sales of milk by 5% using quota regulation. The model is also used to provide a tentative forecast for the evolution of agricultural production and income during the period 1982–1987. The results seem to suggest that agricultural production and income will increase significantly over the forecasting period even with a ‘prudent’ price policy.
