According to Kathleen (1989) agency theory has developed developed along 2 lines. One of them is positivist have focused almost exclussively on the special case of the principal-agent relationship between owners and manargers of large public corporations. Second one is Principal-agent line.

So I think that this theory very helpful for our future work. SHould learn it….
