INCOME ELASTICITIES OF DEMANDS FOR FOODS IN GREAT BRITAIN
利用英国家庭调查数据，分析收入与家庭构成对脂肪、奶酪和胴体肉等食品需求的影响，采用几乎理想需求模型处理零支出问题。
This paper describes analysis of data from the National Food Survey to determine the influences of household income and composition on household demand for foods in 1974, 1979, 1980 and 1982. The paper focuses on fats, cheese and carcase meats. The analysis uses household level data, regarding zero expenditures as arising because of infrequent purchasing and the expenditure‐income relationship used in the Almost Ideal Demand Model. This is in contrast with the analysis reported by the National Food Survey Committee which uses a constant elasticity model and averaged income and expenditure data.
