Abstract
Globalization is a very up-to-date and highly debated topic, since economists have realized that the human society has really changed since the beginning of globalization. However, this observation is not new. Human society has always practiced international exchanges with trade routes like the Silk Road in Asia. Marco Polo is one of the forerunners of this trend. This open topic means different things to different people, and it is very hard to give a real definition. We may only say that globalization is very close to the ideas of a global village, single world society, and modernization. The world is becoming interdependent, and interconnected with respect to economy, as boundaries do not exist anymore.
To explain globalization we will first see what the different theories which appeared through centuries from mercantilism to International investment are. Then we will identify the link between the origins and the benefits. There are several benefits, but globalization also has limits which we cannot ignore.
