Indifference Curves - Income and Substitution Effects for Inferior Goods

​In this revision video we look at the income and substitution effects for an inferior good.
​When the price falls, the substitution effect is NEVER perverse, it will always cause more to be demanded. But in the case of an inferior product, the income effect works in the opposite direction to the substitution effect.
Only if the substitution effect outweighs the income effect will demand expand when the price falls.

I have one question you have make the graph for price decrease but in the case of price increase than would we make that graph other than budget line moves to left?

Hello! Will the concept and the diagram apply to giffen goods as well or do giffen goods have a different diagram?

[@cocodee7863]

Giffen goods will be different because the income effect tends to be bigger than the substitution effect. That's how I try to differentiate between the 2

In this example, does this make Nuts a normal good (as we buy more nuts due to the income effect) or can we not tell from this graph?

[@francescomondini7065]

how do inferior goods react when their price increases?

[@tutor2u-official]

Sales fall because the substitution effect out weighs the income effect
