The growth, range and complexity of problems facing the modern corporation mean that many managers must acquire new skills.

I didn't have anything to read, and I had three hours of travel, so I skimmed through this entire book, just because it was colored violet. It was much too technical for me, although I was able to imbibe its general principles: economics is merely an approximation, because the choices made by most people aren't rational. For example, I'm a medical doctor, but decided to read this book just because I didn't have anything to do and it had a violet cover.
Those idiosyncrasies aren't covered by economics. I still think, however, that the book is a compendium of illuminating articles for the hardcore economist. The first and final sections of the book were intriguing, even to me.
