Expenditure Elasticities for Major Food Groups in Yemen Pre and Post War

The purpose of this paper is to highlight changes in household income and estimate the elasticities of expenditure on food groups in Yemen pre and post war through a personal interview by a questionnaire form for a random sample consisting of 200 households in four Yemeni governorates, namely Sana'a, Ibb, Hadhramaut, and Aden, where then estimated expenditure elasticity for the 12 most important food groups And one non-food group is (group of cigarettes, tobacco, and qat), as it represents an important percentage of a household's daily expenditures. The expenditure elasticities estimates in post-war recorded a decrease for all food groups compared to the pre-war period, except for the expenditure elasticity of fish, which increased from -0.3 as an inferior good in pre-war to 0.5 as a necessary good after the war. And the income elasticity of cereals recorded decrease from 0.96 to 0.3. Finally, the expenditure elasticity on (group of cigarettes, tobacco, and qat), as a non-food group achieved a decrease from 1.5 as a luxury good before war to 0.9 as almost a normal good post the war period.
