Hicksian demand is a way of looking at how much of an item people want to buy when its price changes. Put simply, Hicksian demand is the amount of an item people will buy after they have decided how much they can afford to spend. Let’s say a person can only afford one type of candy. When the price of that candy goes up, the person will buy less of it because they won’t be able to afford it. The amount they can afford after the price change is the Hicksian demand.
