With these goods, their high price is associated with a high social status symbol. As such, high-income consumers find these goods more desirable at a higher price. The income effect has little impact on these goods because income is not a factor. Substitution is also a minimal factor because the goods are generally status symbols and not cross-dimensional.

Key Takeaways A Giffen good is a low income, non-luxury product for which demand increases as the price increases and vice versa. A Giffen good has an upward-sloping demand curve which is contrary to the fundamental laws of demand which are based on a downward sloping demand curve. Demand for Giffen goods is heavily influenced by a lack of close substitutes and income pressures.
Veblen goods are similar to Giffen goods but with a focus on luxury items. Article Sources. Investopedia requires writers to use primary sources to support their work. These include white papers, government data, original reporting, and interviews with industry experts. We also reference original research from other reputable publishers where appropriate. You can learn more about the standards we follow in producing accurate, unbiased content in our editorial policy. At point K price is lower than the disequilibrium 5 point L and demand is lower than supply.
Therefore price will fall, again to minus infinity. This is not plausible because both supply and demand would fall to minus infinity, whatever that means. If we land at point L and nothing else changes, no shift in supply or demand, then the market will stay there; but this is problematic, because supply and demand curves are always and ever shifting.
At point M as any other point between L and N , the demand curve is upward sloping and greater than supply, leading to increases in price, supply, and demand. At point N and above the slope of the curve changes because the price of the Giffen good has risen so much that it is now worthwhile for the individual to buy the normal good. The demand curve then starts to resemble the traditional format downward sloping. If the substitution effect never increases enough to offset the income effect, the normal good has to be a complement.
In that case the curve slope will change when the individual allocates all of his income to the inferior good yet another unrealistic scenario , and any increase in prices will necessarily cause a reduction in quantity. At any rate, as price continues to rise between N and O the quantity demanded will diminish, while the quantity supplied will increase, until an equilibrium is reached at point O.
Notice that location at any point between L and O will lead to equilibrium point O. At point P this curve behaves like a traditional supply and demand model, and greater supply than demand will cause prices to fall. This will go on until an equilibrium tends once again to be reached at O. Finally, the Z curve takes into account that a good only acquires Giffen characteristics above a certain price.
The consumer only reduces the quantity, as prices go down, in order to acquire superior goods e. Below a certain price level, however, the consumer reaches a point where the marginal utility of money spent on the Giffen good is higher than the money spent on the superior goods, because the Giffen good has become so cheap.
In other words, at this threshold the price will become low enough so that the income effect will be greater than the substitution effect. At point J between H and K , however, the curve reaches the price threshold mentioned above.
Below that point the demand curve becomes downward-sloped again, and along it quantity will increase as prices fall. Eventually prices will decrease until the equilibrium point H tends to be reached, where demand equals supply. Bellow that point demand will be greater than supply, causing prices to rise until an equilibrium is reached once again at H. Figure III the Z curve. The Z curve demonstrates that there can be no economically meaningful equilibrium in the case of a Giffen good.
Therefore, any Giffen-like characteristics must be transitory and exist only during the disequilibrium caused by a shock. Quantity and prices will tend towards an equilibrium in one of the downward sloping segments of the curve, either below Giffen prices or above them.

What Is an Inferior Good? Understanding Inferior Goods. Inferior Good Examples. Consumer Behavior. Inferior Goods and Giffen Goods. Normal Goods and Luxury Goods.
Inferior Goods FAQs. Key Takeaways An inferior good is one whose demand drops when people's incomes rise. When incomes are low or the economy contracts, inferior goods become a more affordable substitute for a more expensive good. Inferior goods are the opposite of normal goods, whose demand increases even when incomes increase.

Income Effect Definition Income effect is the change in demand for a good or service caused by a change in a consumer's purchasing power due to a change in real income. What Determines a Normal Good A normal good is a good that experiences an increase in its demand due to a rise in consumers' income.
Normal goods include food staples and clothing. What Is Luxury Item? A luxury item is not necessary for living but is deemed as highly desirable within a culture or society.
