As his students used to say in MIT Sloan (where he teaches), if Pindyck ever teaches a class in anything, just take it, he's so good. This book makes business economics simple and relevant. It is at the same time thorough and advanced. After having gone through it, you'll be surprised at how much can you learn in such a short time. This is possibly also among the best books about business strategy that you'll find. Those that criticize "text-book economics" as irrelevant to every-day business have not read Pindyck-Rubinfield's Microeconomics.
