Download (339kB) | Preview
Using household surveys from Yemen and Djibouti, the paper analyzes determinants of qat consumptions in two countries. The results confirm huge importance of qat in daily life: with between one-half (in Djibouti) and 70 percent (in Yemen) of all households reporting at least one user. But in Yemen, qat consumption is remarkably flat across income groups, age, and between rural and urban areas. Qat is a normal good and there is no indication that its use substitutes for food. In Djibouti, however, qat consumption increases with income, and appears to act as a substitute for food consumption. In both countries however there is a strong gender bias in the use: men are much more likely to use qat than women.
