Duopoly
Market
It
is a market where only two sellers available and they are free from each other
to take any decision. They know each other very much and other activity. They
have no agreement but if any one of them start to make a change in price or production
then it affect the other & it start a chain reaction system which is a
wrong thing for market. If they assume that there is no effect in each other
and make sourly decision then it is a good thing for market.
