Growth of the private sector and privatization of state companies around the world have led to the emergence of various stock markets, some of which are depicted by insider trading. Law literature uses the arguments of unfairness, breach of fiduciary rights and damage to others to define and rule against insider trading.

It advocates structural changes in the developing markets and examines the conditions under which the Coase Theorem would work. (shrink)
