The West Bank olive market
构建了1968-85年西岸橄榄子部门的经济计量模型，分析影响青橄榄供需的技术和行为因素，并用于预测和优化种植者收益，对政策制定者和橄榄行业决策者有实用价值。
An econometric model of the West Bank olive subsector was constructed for the period 1968-85, to provide a means of assessing the technical and behavioural forces that regulate the supply of and demand for green olives. A system of demand-and-supply equations was estimated using the two-stage least-squares (2SLS) procedures. Farm prices of green olives were found to be significantly related to quantity and per-head food expenditures. A reduced-form solution to the structural model was derived to test the forecasting ability of the model to predict the endogenous variables when the exogenous variables are given. The model was used to determine the allocation of the West Bank olives which could maximize returns to growers. The model should be both a useful tool for policy makers and of practical value to decision makers in the olive industry.
