giffen goods Definition, Latest News, and Why giffen goods is Important?



Demand is the relationship between quantity of goods and the price of goods. Imagine yourself going to market with a Rs 100 note to buy apple. If the price of apple is Rs 50 per kg, you may want to buy more quantity compared to if the price is Rs 200 per kg. The demand schedule serves as the basis for the demand curve.

A Giffen good may be defined as a non-luxury product or a commonly used product. Its demand increases when the price rises and demand falls when the price falls. Examples of Giffen goods are rice, wheat, potato, onion etc. Giffen goods cases study the effects of these variables on low-income, non-luxury goods which result in an upward sloping demand curve.

An isocost line is defined as locus of points representing various combinations of two factors, which the firm can buy with a given outlay. Higher isocost lines represent higher outlays and lower isocost lines represent lower outlays. Fixed and variable input Fixed inputs are constant for a certain level of output for a certain period of time and firms can not make any changes in it readily or in a short period. Examples of Giffen goods can include bread, rice, and wheat. These goods are commonly essentials with few near-dimensional substitutes at the same price levels.

Demand is described as being inelastic if its absolute value falls between 0 and 1; unitary elastic if it equals 1; and elastic if it exceeds 1. Inelastic demand, which has a small value, indicates that changes in price have little impact on demand. High elasticity predicts that consumers will buy significantly less of the good in response to a price increase. See the section of the article titled “Selected Price Elasticities” for examples of the elasticities of specific goods. The indifference curve is a graph in economics that displays different pairings of two items, typically consumer goods, that produce the same level of satisfaction or utility for a person.

Variable inputs are those inputs of production that a firm can use as per its requirement and make changes in it easily. For example, raw materials of production, labor, capital, etc. Giffen goods are those goods that show a negative income effect, but a positive price effect. Here “negative income effect” is common with inferior goods, that’s why all Giffen goods are inferior goods. While defining Giffen goods as well as inferior goods, we mention that both refer to those goods which shows a negative income effect.

decreased marginal utility. Therefore, the principle of diminishing

Bread is a classic example of such goods because if the price of bread increases. The poor person will still buy more bread because he cannot afford other luxury items such as meat.

A market is a place where buyers and sellers meet each other through various modes for buying and selling of goods or services. Further, the market is governed by two important forces of demand and supply. These forces help in determining the price of the product and service and market share. The market mechanism always works towards bringing equilibrium in the market. In the section one we will discuss about the demand and its determinants and the Law of Demand.


The unconventional demand for Giffen goods is influenced by income pressures and lack of close substitutes. Focus on low-cost products, whereas Veblen goods focus on luxury, unique, and premium items. When compared to Giffen items, Veblen products concentrate a greater emphasis on high-end goods and services. These factors should not arise if they arise; they affect the supply directly or indirectly. It is very easy to understand that more income will translate into more demand. With increased income, there is more disposable income in people’s hand which they would like to spend, thus there is increase in demand too.

In Economics, the law of Demand is true to the lines for most cases. For instance, even if the Price for Cigarettes goes up, its Demand won’t decrease. The exceptions to the law of demand typically suit the Giffen commodities, Veblen, and essential goods. Although the demand curve for Veblen goods has an upward slope, it is affected by a variety of factors. Perfumes promoted by celebrities or expensive wines are examples of this.

Luxury Goods

Even if the price increases, the demand for salt won’t degrade. This theory comes as the exact opposite of the law of Demand. For all the necessary goods, the demand stays the same, even in the price increment.

  • Thus, it violates the law of demand by showing an upwards-sloping curve of the demand.
  • These too are goods that show behavior like Veblen goods in terms of the abnormal demand curve i.e. demand increases with price.
  • The supply and demand for Giffen items is an extremely rare phenomenon.
  • It must constitute a substantial portion of the total consumption relative to the consumer’s budget.
  • Giffen goods can be the result of multiple market variables including supply, demand, price, income, and substitution.

Giffen goods are usually essential items as well which then incorporates both the income effect and a higher price substitution effect. Since Giffen goods are essential, consumers are willing to pay more for them but this also limits disposable income which makes buying slightly higher options even more out of reach. Overall, both the income and substitution effects are at work to create the unconventional supply and demand results. The laws of supply and demand govern macro and microeconomic theories. Economists have found that when prices rise, demand falls creating a downward sloping curve. When prices fall, demand is expected to increase creating an upward sloping curve.

There may be a significant substitution effect in addition to direct substitution. The substitution effect adds support to the basic economic theory of supply and demand because most items may be replaced. A Giffen good, a concept commonly used in economics, refers to a goods that people consume more of as the price rises. Therefore, a Giffen goods shows an upward-sloping demand curve and violates the fundamental law of demand. Giffen goods can be the result of multiple market variables including supply, demand, price, income, and substitution.

Instead, the growing demand in the capital goods industrial segment, driven by overall investments from the public and private sector, may be a preferred area of opportunity to outperform the market. To prove the idea of Giffen goods, two scientists, Nolan Miller and Robert Jensen of Harvard economist experimented in 2007 in Hunan and Gansu . The staple crop of Hunan was Rice, whereas the staple crop of Gansu was wheat. Lowering the price of Rice in Hunan through a subsidy also decreased its demand. Further, on removing the subsidy, the demand again increases. However, in Gansu, this behaviour was fragile due to the availability of other substitutes and the poverty of households.

Hus an isoquant or isoproduct curve represents different combinations of two factors of production that yield the same level of output. Inferior goods refer to those goods which show a negative income effect. In both Giffen and Veblen Goods demand curve is upward sloping and the demand for the commodity behaves unconventionally. It is a low-income product which does not confirm with the law of demand as the demand of the product decreases with the decrease in the price of the product.

  • The absence of close substitutes, as well as economic considerations, have a significant impact on the demand for Giffen products.
  • Therefore, here as we can see that even with an increase in income demand for millets reduces.
  • As indicated in the example above, rice represents 80% of the quantity demanded of grains.
  • Even if there is an increase in the price of the goods, the current good should still be an attractive option for the consumer.
  • The law of demand states that if all other factors are equal, the demand for a good is inversely proportional to the price of the good.

For instance, if the price of corn increases, consumers will be enticed to buy less corn and substitute it for other foods, resulting in a decrease in the overall amount of corn that consumers demand. The change in income of a consumer or a family also determines the Demand for a particular product. If a family’s income increases, they may choose to buy a specific product in more quantity, no matter the Price. Again, if the family’s income decreases, they can select to reduce product consumption to an extent. The total amount spent on the goods must be large relative to the consumer’s budget.

Law of diminishing marginal utility states that as we go on consuming more and more units of a product, the marginal utility keeps on decreasing. The demand curve for the majority of goods, if not all of them, follows this rule. All taxes are paid by the consumer when the demand curve is vertical and perfectly inelastic. The mindset of the consumer behind this behavior is that now he can afford wheat flour because of his increase in income. Therefore, he will switch his flour demand from jowar to wheat. Hence jowar, whose demand has fallen due to an increase in income, is the inferior good and wheat is the normal good.

The slope of the budget line is the relative price of good A in

Income elasticity -If the salary rises by 10% then the demand for the good should rise by 10% , more than 10% , less than 10% . Superior goods are those which have higher demand with increase in income of person. Will ‘sell in May and go away’ be a good idea for investors this year? Investors are questioning whether the “Sell in May and Go Away” adage will hold true after the recent 6% surge in the Nifty.

An isoquant is convex to the origin because of the diminishing giffen goods example in india rate of technical substitution. Marginal rate of technical substitution of factor X for factor Y may be defined as the amount of factor Y which can be replaced by one unit of factor X , the level of output remaining unchanged. According to the Giffen good definition, it denotes the non-luxury and inferior products with very little or no substitutes. The goods should have very little or no substitute option. If it does have any substitute, then the substitute must cost more than the actual good, even if the price of the good increases.

Each province distributed vouchers to randomly selected households in order to subsidise the purchase of basic goods and services. It was observed in Hunan houses, according to Jensen and Miller, that Giffen-like behaviour was present. Because of price decreases in response to subsidy elimination, household demand for rice decreased, whereas an increase in rice prices as a result of subsidy elimination had the opposite impact. Gansu, on the other hand, showed little signs of wheat production. A demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded by consumers. It shows the quantity of a good or service that consumers are willing and able to buy at different prices.
