The paper analyzes the demand of main consumption groups in Egypt to extraction parameter estimates of these groups. The consumer demand studies in Egypt are limited especially in addressing the demand groups. This paper considers elasticities of main consumption groups by estimating the linear approximation almost ideal demand system (LA/AIDS) using cross-sectional data from the Egyptian 2012/2013 household income and expenditure and consumption survey (HIECS). The estimated model was done by the Iterated Seemingly Unrelated Regressions (ISUR) estimator with the homogeneity and symmetry constraints imposed. The principal findings indicated that the Marshallian own-price elasticities were negative for main groups except for health, transport, and restaurants and hotels while the signs of expenditure elasticities were positive that meaning all groups are normal or luxury groups.

<p>This paper estimates substitution in consumer demand for coffee product categories in Japan using the linear approximate quadratic almost ideal demand system model (LA/QUAIDS). Three expenditure shares and demand equations for coffee beans and powder (beans/powder), canned and bottled coffee (canned/bottled) and coffee drunk at coffee shops (coffee shops) are estimated for two or more person households in forty-nine cities for the period January 2000 through February 2015. The expenditure elasticity estimates indicate that coffee shops are luxury goods while beans/powder and canned/bottled coffee are necessities in the Japanese household. The demographic effects show that persons over the age of 65 and people who earn more consume coffee at coffee shops. Moreover, seasonal effects show demand for canned and bottled coffee as mostly positive while it is mostly negative for coffee drunk at coffee shops in most of the months. The findings of this study indicate that coffee product categories in the Japanese market are substitutes for one another, which is consistent with the reality of coffee consumption in Japan.<strong></strong></p>
