(1) upward rising Explanation: A Giffen good is a good whose consumption in-creases as its price increases. (For a normal good, as the price increases, consumption decreases.) Thus, the demand curve will be upward instead of down-ward sloping. A Giffen good has an upward sloping demand curve because it is exceptionally inferior. It has a strong negative income elasticity of demand such that when a price changes the income effect outweighs the substitution effect and this leads to perverse demand curve.
