Abstract
Linear versions of the Almost Ideal Demand System are estimated for US and German coffee imports with the intent of testing for homothetic a nd non-homothetic weak separability and calculating elasticities. Thre e different separable groupings are tested and separability restrictio ns are rejected. Elasticities indicate both elastic and inelastic dema nd for coffee by country of origin, and also that roasters consider su ch coffees as both substitutes and complements.
