Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

As I have already defined negative externality in another question. However, Let's us understand it once more. Negative externality is the cost to the third party or the society in an economic transaction whether consumption or production. For example, I purchase a speaker which costs something to me. Now, if I play this speaker very loudly, I will surely disturb my neighbours which is nothing but a kind of cost to my neighbours or whatever which we call negative externality. Hence, in case of negative externality, social cost is greater than the private cost.
