TIME VARYING DEMAND FOR ORANGES IN THE EEC
研究了欧共体橙子需求随时间的变化，使用时变参数模型评估贸易政策影响并预测1990年前的消费量，对农业经济学家和政策制定者有参考价值。
Orange consumption is of special interest to the EEC since three new citrus‐producing countries are scheduled to enter into the community. Demand for sweet oranges has changed over time as EEC trade policies change. Time varying parameters procedures are used to evaluate the dynamics of orange demand in the community of nine. The demand estimates are then used to make consumption projections through 1990. The merits of TVP models are contrasted to those of OLS.
