Estimates of Food Demand Elasticities for Great Britain: 1972–1994
利用英国国家食品调查的时间序列数据，采用贝叶斯方法估计近乎理想需求系统，得到符合消费者静态最优的希克斯、马歇尔和支出需求弹性，发现总体食品需求缺乏价格和收入弹性，肉类除外。
This paper reports the results of the estimation of Almost Ideal Demand Systems (AIDS) for UK food demand using time series data from the National Food Survey. A Bayesian approach is used to impose curvature restrictions in the model. The aim is to obtain estimates of Hicksian, Marshallian and expenditure demand elasticities for UK food which are fully consistent with static optimisation by consumers. Overall, the results concur with expectations as aggregate food demand is both price and income inelastic and individual food categories are mostly price and income inelastic. The notable exception being meat, specifically pork, beef and chicken.
