What is a Giffen good and how does its unique characteristic impact consumer behavior and demand in the market?

A Giffen good is a type of product for which demand increases as the price rises, contrary to the law of demand. This unique characteristic impacts consumer behavior by creating a situation where people buy more of the good as it becomes more expensive, often due to limited income and the necessity of the good. This can lead to a higher price and increased demand, creating a feedback loop that is different from typical market behavior.
