Competition (economics)
In this article, it talked about the effect of comptition, history point, and competition in real market, but it is diffcult to understand, because it does not have some example. In addition, it just consider about competition in supply market but not in demand market, it may also need to consider about competition policy for example:cartels((Motta, 2004)) In conclusion, this is a good article for people to understanding competition.
