abstract:In economics, a complementary good is a good with a negative cross elasticity of demand, in contrast to a substitute good. This means a good's demand is increased when the price of another good is decreased.
If it can make the disposable part of the operation, the one-serving K-cups, ubiquitous and cheap, and available in a lot of valued brands, then it can charge high prices for those aspirational machines, the long-lasting complementarygood.
But I think that's where the AU, the African Union, and the UN and the international community can play a goodcomplementary role with the Africans leading the mediation, and the international community making sure that everybody knows that the pressure is there.
