Anthony Bopp (1983) proposed that kerosene, a low-quality fuel used in home heating, was a Giffen good. Schmuel Baruch and Yakar Kanai (2001) suggested that shochu, a Japanese distilled beverage, "might" be a Giffen good. In both cases, the authors offered supporting econometric evidence. However, the empirical evidence has been generally considered to be incomplete. In a 2005 article, Sasha Abramsky of The Nation conjectured that gasoline, in certain circumstances, may act as a Giffen good. However, no supporting evidence was offered, and evidence from the large increases in oil prices in 2008 would suggest that quantity demanded for gasoline did actually fall as a result of increased prices. Of course, the lack of evidence at the aggregate level does not rule out that the proposed goods may have been Giffen for certain groups of consumers---in particular for poor consumers.
The great recession has raised the possibility that very safe financial assets (Treasuries, cash, gold) become Giffen goods in liquidity trap scenarios or during bad economic times. As investors fear lower returns in equities and other investments they minimize risk by purchasing more of a low return, higher price asset that is considered safer.
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.
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.

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.

The unique demand behavior of a Giffen good in the market is influenced by factors such as the lack of close substitutes, income effect outweighing the substitution effect, and the necessity of the good for basic needs.
