What do you mean by a normal good?
Advertisements
उत्तर
Those goods that share a positive relationship with income but a negative relationship with price are called normal goods. In other words, if the income of a consumer increases, then the demand for a normal good also increases. However, the demand will fall with the rise in the price of that good.
That is,
If the price of a good (Px) increases, thenthedemand for good (Dx) decreases
If a consumer’s income (M) increases, then thedemand for good Dx increases.
