PRICE DISCRIMINATION

This means that exploiting demand characteristics to allow the sum product to be sold at various prices unrelated to the cost of supply

In short we can say that in the markets a single consumer may be charged different prices for different units of a good bought or different consumers may be charged different prices for the same product or services  

This price discrimination is divided into three types

1)prefect price discrimination:

This is 1^st degree in this it identifies each individuals and charge price accordingly

For example we can take auctions

2) market/segment based price discrimination:

This is well defined segment u cant change from one to other and in this price vary from segment to segment

For example if student has less money the goods and prices for them will vary from well salaried employee

3)self selection by price discrimination:

In this u have the right to select your price

For example we can see many movie theaters in which there will be different classes according to the income of the customers
