The law of demand states that individual demand curves are negatively sloped. To date, the Giffen Paradox represents the only analytically valid exception to the law under standard assumptions. This article shows that if consumption externalities exist, it is possible for the individual's demand curve to slope upward. In particular, the condition under which demand becomes upward-sloping can be delineated in terms of measures of elasticity of demand. (JEL D11, D62).
