英文摘要 | Data from the survey of family income and expenditure, conducted by Directorate General of Budge, Accounting and Statistics, in 1984 and 1993 are employed for analyzing structural changes in household food expenditures. An explicit Engel function is specified as the empirical model. The results of Chow-test inducate there exist structural changes on the demand parameters of 17 food groups between two sample years. Furthemore, the empirical results indicate that most of the changes in food expenditures are caused by the changes in income, demographics, and social - economic factors between two the sample years, with changes in demand parameters playing a secondary role. |
