Modelling demand and price equations of the Italian agricultural sector
构建了一个模型，用于确定食品消费、零售价格、进口和营销服务，将食品分为动物源和植物源，发现消费者食品支出缺乏收入弹性和价格弹性，而进口对收入变化敏感但对价格变化不敏感。
A model is presented, which determines consumption, retail prices, imports and marketing services of food products, separated into food of animal and $$$ vegetable origin. The relations are specified employing distributed lags, the coefficients of which are restricted so as to secure long run dynamic equilibrium. The resulting equations indicate income and price inelastic consumer food expenditure, whereas imports are very sensitive to income changes, but not to price changes. Retail price changes are found to be dominated by marketing service price changes.
