| | GIFFEN, HEINER, AND THE LAW OF DEMAND |
 | | The Giffen good, whose existence in theory is rarely denied but whose existence in reality is in serious doubt, constitutes an exception to the general Law of Demand: an increase in price is accompanied by an increase, rather than a decrease, in the quantity demanded. |
 | | The Giffen good is the result of circumstances under which the ceteris paribus assumption, even in the less-than-strict sense, cannot hold. |
 | | But allowing for the possibility of a Giffen good does not constitute a shortcoming of traditional methods; this theoretical possibility, rather, must be allowed for in the traditional theoretical framework and in any other theoretical framework, including Heiner's. |
