Table 1. AIDS Elasticities.

Expenditure elasticity	${\mu }_i=1+\frac{({\beta }_i+{\eta }_i^{\prime }z)}{w_i}$
Non-compensated own and cross price elasticity	${ϵ}_{ij}^u=-{\delta }_{ij}+\frac{1}{w_i}({\gamma }_{ij}-[{\beta }_i+{\eta }_i^{\prime }z]\times [{\alpha }_j+{\displaystyle {\sum }_{i=1}^k}{\gamma }_{ij}\ln p_i\left]\right)$
Compensated own and cross price elasticity*	${ϵ}_{ij}^C={ϵ}_{ij}^u+{\mu }_i{w}_j$

* Compensated elasticities obtained by a Slutsky equation.
