Honestly this time I don’t want to talk in mere academic language, today I just want to express a feeling I got when reading about Price Theory. That would be: Beauty. Not because its perfection nor because is liberal, just because point out something so coordinated and complex that happen in the very same world we live and we are part of. I mean the topics on gibbons or elephants in Africa are interesting, and the history of the XVII century can be as well as a Dickens novel, but in this case is something that we are part every day of our lives. I won’t explain my understanding of this, first because I think many of my colleges can do that in a clearer way than me, but mainly because the feeling of surprise and wonder is still so fresh in my mind. The fact that thousands, millions, actually uncountable actors in the process of fixing prices, each acting but at the same time being influenced by the rest without any central authority is so beautiful that I want to share this with you.
