Indifference curve analysis with its technique of looking upon the price effect as a combination of income effect and substitution effect explains relationship between price and quantity demanded in a better and more analytical way. A distinct advantage of viewing the price effect as a sum of income effect and substitution effect is that through it the nature of response of quantity purchased to a change in the price of a good can be better and easily explained. In case of most of the goods, the income effect and substitution effect work in the same direction.
Income elasticity of demand YED measures the responsiveness of demand to a change in income. A luxury good means an increase in income causes a bigger percentage increase in demand. It means that the income elasticity of demand is greater than one. When income rises, people spend a higher percentage of their income on the luxury good. An inferior good means an increase in income causes a fall in demand.

Substitution Effect, Income Effect, Normal and Inferior Goods PDF Download There are two different phenomena underlying a consumer's response to a price drop: As the price of a product declines, the lower opportunity cost will induce consumers to buy more of it since it becomes less expensive - even if they have to give up other products.
In economics and consumer theory , a Giffen good is a product that people consume more of as the price rises and vice versa—violating the basic law of demand in microeconomics. For any other sort of good, as the price of the good rises, the substitution effect makes consumers purchase less of it, and more of substitute goods ; for most goods, the income effect due to the effective decline in available income due to more being spent on existing units of this good reinforces this decline in demand for the good. But a Giffen good is so strongly an inferior good in the minds of consumers being more in demand at lower incomes that this contrary income effect more than offsets the substitution effect, and the net effect of the good's price rise is to increase demand for it. Also known as Giffen Paradox. A Giffen good is considered to be the opposite of an ordinary good. Giffen goods are named after Scottish economist Sir Robert Giffen , to whom Alfred Marshall attributed this idea in his book Principles of Economics , first published in
Economics Essays pp Cite as. According to a well-known result by W. Hildenbrand , if all consumers possess the same demand function and the density of the expenditure distribution is decreasing, than the average income effect term is non-negative even if inferior goods are present, so that the aggregate demand must be monotone. We show that if the expenditure density is uni-modal and a certain relation between the income density and individual demand is satisfied, than the average income effect term is negative and Giffen goods are not ruled out. We show that the lowest-grade rice-based Japanese spirit shochu satisfies this condition. The data suggest that this commodity might be a Giffen good.
Various types of goods are studied in economics, like normal goods, inferior goods, luxury goods, Veblen goods, Giffen goods. Giffen goods are goods whose demand increases with the increase in its price and vice versa. As the income effect of Giffen goods and Inferior goods is negative, the two are commonly juxtaposed for one another. So, this article might help you in understanding the difference between Giffen goods and Inferior goods. Basis for Comparison Giffen goods Inferior Goods Meaning Giffen goods refers to those goods whose demand goes up with the rise in the prices. Inferior goods are goods whose demand falls down with the rise in the consumer's income over a specified level.

DOI: Nesse artigo, discutimos brevemente os problemas do modelo tradicional, propondo um melhor: a curva Z. Keywords: Demand curve, supply curve, Giffen good, consumer theory. Abstract: The demand for a Giffen good is atypical, i. The traditional representation for this phenomenon is a simple upward sloping demand curve. This model is very problematic, because it implies that demand can oscillate between infinity and negative infinity, an unrealistic scenario to say the least. In this paper we briefly discuss the problems with the traditional model and propose a better one: the Z curve.
Suppose we regard consumption today and saving today leading to extra consumption tomorrow as two "goods", and that they are the only goods available. Which of the following statements must hold when an individual is maximising her utility? Are all Giffen goods inferior goods?
Answer: All Giffen goods are inferior. For a Giffen good, the income effect must be negative; that is a fall in income increases demand. Not all inferior goods will be Giffen goods too; if the income effect is small relative to the substitution effect, a usual shaped demand curve results.
