The Theory of Comprative Advantage

We are living in an increasingly global and integrated world. So much of the stuff i'm using right now, while we're doing this recording, is imported from all over the world. The headphones i'm using a japanese. And they're all made with materials which were souce from different countries around the world. I try to be a bit strategic about when i convert my money into pounds sterling, because sometimes fluctuations could make a difference of even a few hundred pounds on my end.
