Hey /biz/
What are some recommended reads in relation to biz and economics textbooks.
In the last year I've built a fairly successful business and concepts I learnt in high school which I thought were useless have become extremely beneficial to me and in a major way has set me apart from competition. Concepts like vertical integration, opportunity cost, complimentary services etc. (I know it may seem basic but it's like i'm operating on another level to these guys.)
The few books i've read are more like biographies and self help or baby's first book for business like "Input - Output = Profit" but i want a more advanced, hard facts book to efficiently learn more of these invaluable concepts.
Your /adv/ is appreciated.
