A Giffen good is a type of product that people buy more of as the price increases, contrary to the law of demand. This is because the good is considered a necessity and consumers are willing to sacrifice other goods to afford it. This differs from other goods where demand decreases as price increases, following the law of demand.
The phrase "All Giffen goods are inferior goods, but not all inferior goods are Giffen goods" implies that a company called Giffen only creates goods that would be deemed inferior. By contrast, however, it cannot be assumed that any inferior good has been produced by the Giffen company.
Yes, but not all inferior goods are Giffen goods!
All Giffen goods are inferior goods. But not all inferior goods are Giffen goods. For inferior goods, the negative substitution effect will more than offset the positive income effect, so that total price effect will be negative. For Giffen goods, the positive income is positive and very strong that the law of demand does not hold. Price elasticity of Giffen good is positive. Inferior Goods: Cheap goods Giffen Goods: Rice, wheat, noodles are Giffen goods in China
Giffen and Veblen goods are examples of the violation of the law of demand. For these two commodity types, as price increases, so does demand for them.

Goods that have an increase in quantity demanded in response to an increase in price are called Giffen goods. Evidence of the existence of Giffen goods is extremely limited and there are no known examples of Giffen goods.

=giffen goods are mostly maent for show off while inferoir gods are maent for convinience=demand for giffen goods goes up when their prices go up while demand for inferior goods remains constant despite price fluctuations
The Engel curve shows how household expenditure on goods changes with rising income. Giffen goods are inferior goods. As household income rises, instead of consuming more of the Giffen goods, expenditure is switched to better quality goods. Consequently, the demand for a Giffen good falls as income rises and this results in a downward sloping curve. Incidentally, a curve that slopes "negatively downward" is actually a curve that slopes positively upwards!

Proof that all Giffen goods are inferior goods but not all inferior goods are Giffen goods. A Giffen good is defined as dx/dp > 0 (i.e. quantity demanded increases with own-price). An inferior good is defined as dx/dm < 0 (i.e. quantity demanded decreases with income). The own-price Slutsky equation tells that: dx/dp = dh/dp - x(dx/dm) (own-price elasticity of demand = substitution effect - income effect), where h is the Hicksian demand. dh/dp is always negative. If the good is Giffen, then the left hand side of the Slutsky equation is positive. Since dh/dp is negative, then it must be the case that dx/dm is negative (i.e. the good is inferior), since otherwise a positive income effect subtracted from the substitution effect would give a negative result. Therefore, all Giffen goods are inferior goods. Yet, it may be the case that x(dx/dm) is negative, an inferior good, but that the income effect is lesser than the substitution effect, so that the left hand side of the equation remains negative. Thus, not all inferior goods are Giffen.
In economics, Hicksian demand refers to the quantity of a good or service that a consumer is willing to buy at a given price, assuming their income and preferences remain constant. Giffen goods are a rare type of good where the demand increases as the price rises, contradicting the law of demand. The relationship between Hicksian demand and Giffen goods is that Hicksian demand does not apply to Giffen goods because their demand does not follow the typical downward-sloping demand curve.
